Energy News – Issue 16 3

Dear Reader,In recent years we have seen an increasing number of problems with, or potentialthreats to, energy supply in various countries around the world. Power cuts havebecome more common and as consumption is increasing to the level of installedcapacity, the price of energy, in particular during peak periods, has increasedconsiderably. The general uncertainty in the world economy that has continued forsome time already has kept new power plant investments at a low level andconsequently the situation in many countries has become unbearable.

These circumstances are favouring decentralized energy solutions, either based onelectricity production only or on combined heat and power production. Small-scaleplants offer a myriad of advantages: they can be built fast, the investment is financiallyreasonable, and they can easily be used for peak shaving. As these plants are oftenbuilt close to the consumers they are ideal for combined heat and power production,which in terms of total efficiency far outweighs separate electricity production.

Wärtsilä is increasing and intensifying its range of decentralized energy solutions.During the past few years we have delivered an increasing number of large gas-firedplants alongside the more traditional oil-fired power plants. These plants have provento be very successful.

We are pleased to present to you in this issue articles on the efficiency and otheradvantages of large engine-based, gas-fired power plants and how they compare withother technologies. I hope you find this issue of Energy News both informative anduseful.

Wärtsilä Large Gas Plants –challenging the gas turbines

Wärtsilä offers a winningconcept, large gasengine power plants,that provide a real

alternative to gas turbines indecentralized applications.Advantages include higherefficiency, lower maintenancecosts, less sensitivity to deratingat altitudes, efficient part loadoperation and flexibility fordifferent applications.

Gas is fast becoming the most popularfuel for power generation today. Oneimportant reason for its increasing useis the construction of big gas powerstations using Gas Turbine CombinedCycle (GTCC) technology. Thesestations have to be big in order to beefficient and to reach a competitiveinvestment cost.

However, the introduction of large,high-efficiency gas engines makes this

technology a competitive alternative tobig GTCC plants through their suitabilityfor decentralized applications. Largegas engines reach efficiencies close to50% in simple cycle operation.

Gas engines come of ageIn the past ten years the number of gasengines has increased in gas powerplants with lower outputs, especially inthe range under 5 MW. The diagramsshow how gas turbines dominate thebigger unit sizes and how smaller unitsare dominated by reciprocating gasengines. Figure 1 describes the wholerange while Figure 2 focuses on unitsizes up to 120 MW.

Gas engine power plants areparticularly suitable for CHPinstallations, for district heat productionand for industrial heat recoveryapplications. Along with the increase ingas engine installations the technologyhas also developed considerably in

recent years and gas engines are nowreliable units offering superior efficiencywith low maintenance cost.

The world’s biggest spark-ignitedgas engine is the Wärtsilä 20V34SGengine, which is currently undergoingendurance tests at the increased outputof 9 MW in an installation in Spain.

The biggest gas engine available onthe market today is the Wärtsilä18V50DF engine. This is a dual-fuelengine capable of running on HFO, LFOand gas. In this engine the gas is ignitedby a small amount of LFO pilot fuel. Thisengine has a nominal output of 17 MWand electrical efficiency of 48%.

These engines are closing the gapwith the GTCCs through high efficienciesand competitive investment price, withthe additional benefit of being small anddecentralized.

Theoretical conditionsIf we analyse only the nominal

performance at full load in normalconditions the GTCC still has a smalladvantage. The reality, however, issubstantially different. Figure 3 presentsthe investment costs and efficiencies ofsimple cycle gas turbines. The curvesare the average values for all turbines.Figure 4 gives the correspondingdiagram for GT combined cycles. Thesecurves are for ISO conditions, i.e. at sealevel, an ambient temperature of 15 ºCand no pressure drops.

The average investment cost of asimple cycle gas turbine with an outputof around 50 MW is 300 $/kW and theindicated electrical efficiency isapproximately 35%. The correspondingfigures in Figure 4 give an investmentcost of 700 $/kW and indicatedelectrical efficiency of about 50% for a50 MW GTCC plant.

The investment cost of the best gasengine, the Wärtsilä 18V50DF, in a50 MW turnkey installation is in the

range of 500 $/kW with an indicatedefficiency of 48%. This is a simple cycleinstallation offering fast delivery andgood load response. Based on thesevalues the comparison between gasengines and gas turbines indicates thatthey are equally competitive. That maybe the situation in ideal ISO conditions.

Differences in real conditionsThere is, however, a fundamentaldifference in the derating of gas turbinesand gas engines. The gas engine startsto derate at higher outdoortemperatures, normally well over 25 ºC,which tips the scales in favour of gasengines. Derating also means that thespecific kW cost increases accordingly.

The second big difference betweengas turbines and gas engines is howtheir performance derates withincreased altitude. Here the output of agas turbine starts to decrease as soonas the altitude increases whereas gas

engines do not start to derate untilaltitudes of over 2000 m above sea levelare reached. Figures 5 and 6 showFigures 3 and 4 updated for an altitudeof 1500 m and ambient temperature of25 ºC.

Derating affects both efficiency andinvestment cost. For a 50 MW outputthe gas turbine’s investment cost hasrisen to over 400 $/kW although itsefficiency is still largely unchanged. Thecorresponding values for the GTCC arealmost 900 $/kW and an electricalefficiency of around 48%, indicating thatin these conditions the gas engineoffers clear advantages.

Another factor heavily affecting GTperformance is efficiency at part loads.The part load efficiency of the gasengine remains virtually unchanged welldown to 50% load. Since gas engineplants are normally built up of severalengine units the difference is even morepronounced as individual engines are

Hence, comparing GTs to gasengines depends entirely on ambientconditions and load profiles. Inbaseload applications at sea level andwith low average ambient temperaturesthe comparison between a GTCC andgas engine plant can indicate anadvantage for the GTCC plant.

Plant size is also quite important inthe comparison; for the GTCC, bigger isbetter in order to be competitive. Sizealso creates other problems. Thebackup power needed must be

dimensioned according to the biggestinstalled production unit in the plant. Bigunit sizes demand big backup powerdemand. In the case of a gas engineinstallation with multiple engine units,only one additional engine need to beinstalled to provide the necessarystandby capacity.

The simple, modular design andconstruction of gas engine plantsmakes their installation fast and givesthem the flexibility of incrementalexpansion as needs change. Hence theowner can start with a small plant thatmeets current power demand andenlarge the plant later if power demand

changes. This ensures fast revenue flowwith the ability to keep productionoptimized to demand. Figure 8 shows across section of a 100 MW power plantbased on six 18V50DF units.

Financial considerationsUncertainty in the power market andvariable fuel prices are creating newchallenges for power plant investors.When the fuel price varies the plant’seconomics can change considerably.A plant originally designed for baseloadproduction can end up running atintermediate load when the fuel priceincreases. This not only affects thefinancial side of the plant through lowerincome from power sales, it also has alarge impact on the O&M costs.

As noted above, a big plant designedfor baseload operation does not reach itsoptimal performance at part load. If theload variation is so big that the plantneeds to be shut down during thenight-time, the impact on income can beenormous. GTs, especially the industrialtype of turbine mostly used in GTCCs,suffer heavily from frequent starts andstops. The steam cycle of the GTCCcannot keep pace with the fast startup ofGTs. When comparing startup of GTCCsto simple cycle GTs we are talking abouthours instead of minutes.

The GTCC, though efficient in certainbase load applications, will in this casebe a low-efficiency plant with high O&Mcosts whereas gas engines come intotheir own. The simple plant designenables fast and easy startup. The

nature of these plants also makes themsuitable for both baseload andintermediate load applications.

This also has other advantages. Forexample, in markets with a large shareof hydropower, the gas plants will beoperated according to hydropowerproduction. As the market changes thiscan also mean that existing baseloadplants will be operated as intermediateor even standby plants later on. Theplant technology, therefore, has a bigimpact on the plant’s financialperformance at a later stage.

Progressive development of gasengine technology has also reduced themaintenance costs of these engines.Many satisfied customers operating gasengine plants today report lower O&Mcosts than with aero-derivative gasturbines. The O&M costs are at thesame level as for industrial gas turbines.

Investing in Wärtsilä gas engineplants is also a safe choice from theO&M point of view. Wärtsilä offers totalO&M packages that minimize theowner’s risk.

As today’s power market movesincreasingly towards deregulation anddecentralization, the right solution willbe small- to medium-sized power plantswith high efficiency, low O&M costs andlow emissions levels. Locating theseplants close to the power and heatconsumers will reduce the need forinvestments in transmission lines andbackup power. Looking at the totalpicture these plants will be the clearwinners for their owners. �

Wärtsilä lean-burn gas engine replaces gasturbine at Ringkøbing Fjernvarmeværk

Ringkøbing district heatingcompany in Denmark hasinvested 4.2 M€ to installthe world’s biggest

spark-ignited lean-burn gasengine. This is also Wärtsilä’sfirst commercial 20-cylinder gasengine.

The new Wärtsilä 20V34SG generatingset is situated in the Rindum plant, asubstation in RingkøbingFjernvarmeværk’s district heatingnetwork. Weighing 130 tonnes, it has anet output of 8 MWe and 9.6 MWth. Thenew plant delivers heat to the town’s3,500 consumers and electricity to thelocal utility company RAH.

“The engine design is built on thewell known Wärtsilä technology and forthat reason we had no reservations

about investing in this large engine,”says Jesper Skovhus Andersen, PlantManager at RingkøbingFjernvarmeværk.

A major reason for selecting areciprocating engine, he continues, wasthe fact that the Wärtsilä engineproduces twice as much electricalpower as the gas turbine it replaced.

“When we invested in the gas turbineover a decade ago, we found that gasturbines had the edge over gas engines.But gas engine technology today isclearly superior to gas turbinetechnology and we had no hesitation inchoosing a gas engine when we had tochange.”

The electrical efficiency of the gasturbine was 27% while the efficiency ofthis 20-cylinder gas engine is almost44%.

“We were faced with toughenvironmental demands from theauthorities to reduce the NOX emissionsfrom the gas turbine, in addition towhich a major overhaul was scheduledfor the gas turbine. So we felt it was theright time to consider new productiontechnology.”

Fast-track deliveryThe old gas turbine was resold to thesupplier and the Wärtsilä 20V34SG wasinstalled at the Rindum substationwhere an existing building and stackwere perfect for the new engine. Thenew engine was delivered to the site inSeptember 2002 and the installationwork was carried out as a fast-trackproject with the engine in full operation,delivering heat and electricity to thetown of Ringkøbing just three months

later in December 2002.“We have entered into a

maintenance and service contract withWärtsilä covering all services on theengine up to major overhaul. Thisagreement is cheaper than the contractwe had with the gas turbine supplier,”Jesper Skovhus Andersen adds.

A typical CHP installation in Denmarkoperates 15 hours a day, except forextremely cold days in wintertime whenit is necessary to operate 24 hours aday. This operating pattern does notfavour gas turbines since these operatewith high thermal stress; every startdeducts a minimum of 10 operationhours from the total lifetime, whichnaturally leads to higher operatingcosts.

Technical and economicperformance improvedIt was 13 years ago that RingkøbingFjernvarmeværk, one of the first districtheating companies in western Jutland,decided to convert a coal-fired boiler to

a natural-gas-fired cogeneration plant.At the same time natural gas wasintroduced to Ringkøbing.

At the time, Vestkraft built adecentralized cogeneration plant at theRingkøbings main heat station in thecentre of Ringkøbing. This is equippedwith a 6.2 MW gas turbine owned byELSAM but operated by RingkøbingFjernvarmeværk. National regulationsrequire that at least 90% of the heat isproduced by cogeneration. To complywith this regulation it was necessary tobuild the Rindum substation with a4.1 MW gas turbine.

“Since then the situation haschanged rapidly. The gas turbine is nolonger the optimal solution now that therevenue from electric power productioncontributes substantially to the paybackscheme of the plant,” Jesper SkovhusAndersen explains.

With the Wärtsilä 20V34SG engineinstalled, Ringkøbing Fjernvarmeværk’stechnical and economic performancehas changed drastically. Based on

present estimates, the cost of heatproduction from the Rindum plant hasbeen reduced by 20%, compared withcontinuing operation of the gas turbine.

Wärtsilä, having installed 170 MW ofgas engines in 26 district heatingcogeneration plants in Denmark, has awell-established service network in thecountry. The Ringkøbing plant is servedby the Esbjerg service branch.

The new gas engine plant has nowbeen in operation for four months andhas gained 2300 running hours withoutany major problems.

The total efficiency of the plant isalmost 5% higher than for the gasturbine plant. This is because theoxygen content in the exhaust gasesfrom the gas engine is lower andtherefore a bigger share of theevaporation heat from the exhaustgases can be recovered. The high totalefficiency of the plant is very importantas it gives the owner maximum securityin an open market where fuel andpower prices are volatile. �

The Wärtsilä R&D project forultra low air emissions withgas engines for the USmarket started early in

2000. As a result of this effortthe first commercial project withthis solution was in fulloperation at the beginning of2002.The Ultra Low Emissions (ULE) Solutionis based on secondary emissionreduction technologies, a selectivecatalytic reduction (SCR) system forcontrol of nitrogen oxides (NOX), and anefficient oxidation catalyst system forcarbon monoxide (CO) and volatileorganic compound (VOC) control. Thesystem is specifically designed forWärtsilä SG gas engines.

The first Wärtsilä dual-fuel (DF)engines applying a similar solution willbe commissioned later this year.Feedback from the field is showingpositive results, which gives usconfidence in the future development ofemission reduction technologies for gasengines.

Environmental impact of gasplantsAll power plants have environmentalimpacts. The Wärtsilä lean-burn gasengine, however, is considered anenvironmentally sound alternative in thedistributed power generation business.

The major environmental impacts ofa gas power plant are the atmospheric

emissions. The effective lean-burncombustion technology and the highthermal efficiency of the Wärtsilä gasengines ensure that the air emissionsper kilowatt-hour of electricity producedare relatively low.

The Wärtsilä gas engine can betuned for different NOX emission levelsto meet project-specific needs. Sulphurdioxide (SO2) and particulate emissionsare very low compared to operation onliquid fuels. The emissions of SO2 aredirectly proportional to the sulphurcontent of the fuel being burned. Ingaseous fuels sulphur can be present inthe form of gas odorants and hydrogensulphide (H2S).

Gas suppliers usually remove H2Sfrom the gaseous fuels, resulting innegligible SO2 emissions from gasengines. Abatement efficiencies up to80% of CO can easily be achieved witha CO oxidation catalyst.

Moderate reduction of VOC,aldehyde and other hazardous airpollutant (HAP) compounds can also beachieved with this oxidation catalyst.Besides being dependent on engineoptimization the VOC and aldehydeemissions from the gas engine are alsostrongly dependent on fuel quality, i.e.the composition of the natural gas.

Market demandsA gas engine as such or equipped witha CO oxidation catalyst can in mostcases fulfil the emission limits. However,

in some countries local authorities areapplying stricter emission limits than thestipulated national or federalregulations, especially if the plant will belocated in a sensitive area or degradedairshed.

In the USA it is common practice torestrict the emission limits for maximumallowable emitted tonnes per year,which is stipulated in the plant operationpermit. In practice this means that thehigher the capacity of the plant andrequested annual running hours, thestricter the actual emission limits ing/kWh will be. This makes the majorityof projects in the US unique. It isessential that all environmentalregulations are identified early and takeninto consideration at the planning anddesign phase of the project.

The Ultra Low EmissionsSolutionThe Ultra Low Emissions (ULE) Solutionis based on secondary emissionreduction technologies.

A conventional platinum-basedoxidation catalyst for CO and moderatehydrocarbon emission control have beeninstalled on Wärtsilä gas engines(~700 MW) worldwide since themid-1990s. The control method usescatalyst active metals to accelerate theoxidation reactions between combustiblecomponents and flue gas residualoxygen to carbon dioxide and water.

In order to reach very low emission

levels (ULE) the plant has to beequipped with a more efficient oxidationcatalyst. The active materials in such anoxidation catalyst are usually based onboth platinum and palladium.

The use of Selective CatalyticReduction (SCR) for removing NOX

emissions is a well known technologywithin Wärtsilä. SCR units have beeninstalled on a few Wärtsilä gas enginesand on many Wärtsilä diesel engines(500 MW) since early 1990.

In the SCR process, nitrogen oxidesare reduced by injection of anammonium-based compound to

nitrogen (N2, the major component ofair) and water (H2O). The system can bedesigned to apply either an aqueousurea (32-40%-wt) solution or aqueousammonia (25%-wt) as the reductionagent.

The main components of the UltraLow Emissions Solution consist of thereactor(s) with catalyst, reagent storage,injection and a control system. Figure 1shows two different types of catalystconfigurations based on the Ultra LowEmissions Solutions that are installedwith Wärtsilä gas engines. Theconfiguration is optimized for

project-specific requirements and thetechnical solution of the catalyst vendor.

Important factors in the SCR designare the mixing stage, flue gasdistribution, the amount of catalyticmaterial and the control system. Unlessthere is a perfect mixing of the reagentand exhaust gas in combination with aperfect reactor design, the lastammonia (NH3) molecules will not ‘find’and convert the last few NOX

molecules. This will lead to excessiveammonia injection (NH3/NOX ratiolarger than 1.0), which will eventuallycause ammonia slip in the exhaust gas.

Many different compounds fall underthe collective term VOC. The VOCcomponents are oxidized at differentrates. Saturated VOC, especiallypropane, react the slowest.Unsaturated, oxygen-containing organiccompounds and polycyclic aromaticsreact considerably faster. Theperformance of the oxidation catalystdepends on exhaust gas temperature,the quantity of noble metals (tailor-made

for ULE), the catalyst volume and thedesign (space velocity).

As mentioned earlier the Wärtsilä gasengine can be optimized either foroptimal heat rate or for low NOX

emissions. The latter alternative has asmall negative effect on heat rate andalso on emissions of incompletecombustion products, such as CO andVOC emissions. Calculations show thatthe high efficiency engine setting isfavourable for the ultra low emissionssolution design.

Table 1 presents the emissionguarantees in the commercial projectsin the USA that were used as a designbasis for the Ultra Low EmissionsSolution.

The ammonia slip requirements were0.028-0.047 g/kWh, which correspondsto 5-8 ppm (in wet gas, 15%-vol O2)

A main limitation for the SCRtechnology to reach very low ppm NOX

values originates from the NH3 sliprequirement. In order to achieve verylow NOX and ammonia emissionssimultaneously, the catalyst and controlsystem must be designed with care.

The SCR control system is based onthe engine load signal and a feedbacksignal from the NOX analyser. The ureainjection rate versus engine load curveis set during commissioning of the SCRsystem. The analyser is continuously (orsemi-continuously if the analyser istime-shared between several engines)

analysing the NOX concentration at thereactor outlet in order to adjust thereagent injection rate. This way thesystem corrects for engine NOX

fluctuation due to variations in ambientconditions and consequently theguarantee values can be achieved at alltimes during normal stable loadoperation.

The exhaust temperature from theengine is optimal for SCR operation anddoes not require heat recovery prior orparallel to the mixing ducting of the SCRsystem as is the case in gas turbineinstallations. Both from a mechanicaland operational point of view this is asimple and integrated system.

Good experience from the fieldFeedback from the ULE solutioninstallations is showing positive results.The measured emission values duringcommissioning have all been well belowthe guarantee levels (Table 1) at allinstallations.

Comprehensive pilot testing andsuccessful commissioning is importantin order to develop ULE further. It is alsoessential to follow up the long-termexperience on such installations in orderto optimize and develop theperformance and reliability of thissolution.

What does it cost?The ULE solution has significant

operation and maintenance costs inaddition to the initial investment cost.

The investment, operation andmaintenance costs for a catalyst systemdepend on the capacity of the engine,the uncontrolled emissionconcentration, the desired emissionabatement and the annual operatinghours of the engine. The prices of thecatalytic materials also follow the worldmarket prices of the catalytic activemetals, such as platinum, palladium andvanadium.

Table 2 shows typical investmentcost for different catalyst abatementefficiency systems. Prices are based ona 23 MW power plant operating onnatural gas. Note that the VOC limit andcorresponding percent reduction isheavily dependent on the natural gasspecification. Values for the VOC aretherefore only indicative.

Table 3 presents typical catalystoperating costs for different operationscenarios. The reagent price isdependent on specific site delivery cost,though 370 euros per ton of ureasolution (40%-wt) has been used inthese calculations. In the calculation itwas assumed that the catalyst materialhas to be changed over a 5-year period.The catalyst replacement intervals aredependent on plant-specific operationconditions and will therefore vary fromcase to case.

It is a challenge for the regulatory

authority to focus on the totalenvironmental impact. The totalenvironmental impact includesproduction of the catalyst (containingheavy metals) and reagent (ammonia orurea), transportation of the catalyst andreagent to the site, disposal or recyclingof the used catalyst, as well as addedammonia emissions to the atmosphererather than the last few NOX moleculesin the exhaust gas.

The cost of secondary emissioncontrols to achieve very low emissionlevels, mainly considering NOX, mightbecome excessive, i.e. the overallenvironmental impact may actuallybecome worse. It might not be worththe price to attempt to reach zero level.

Wärtsilä offers reliableenvironmental solutionsBesides the ongoing development ofprimary emission reduction technologiesfor engines, i.e. increasing engineefficiency and optimizing thecombustion processes, the secondarycleaning techniques for ultra lowemission levels are here to stay. It is aninspiring task for Wärtsilä to developsecondary emission reductiontechniques together with oursub-suppliers and to utilize thesetechniques in combination with ourengines as successful solutions. �

Sarayacu crude oilpump station choosesWärtsilä 12V32LN

The Ecuadorian oil sector is divided into 32 blocks.Foreign oil companies have signed agreements with thegovernment in order to receive the rights to explore anddevelop the different blocks.

Perenco, with headquarters in Paris, London and theBahamas, bought the rights to explore Blocks 7 and 21located in the Oriente region in 2002. To get the crude oil tothe market, Perenco needed to construct a pipeline about 50km long to connect to an existing pipeline owned by AGIP. Tokeep the oil flowing, a new pumping station will be built atSarayacu.

1300 m above sea level

The Sarayacu pumping station is located in the Ecuadorianjungle 1300m above sea level at the borderline of Block 21.The pumping station will start to feed the new pipeline withheavy crude oil during 2003.

The site belongs to AGIP, who have been the forerunner inusing crude-oil-fired Wärtsilä engines at their AGIP Villano oilfield in the neighbouring Block 10. With 3 x 16V32LN(21.5 MW) in operation at the Villano field since 1998, AGIPhas proven the technical and economic reliability of this newpower production concept in Ecuador. They are at thismoment installing the fourth 16V32LN for the expansion of theVillano field.

Technology of choice

With this pumping station in operation, Perenco will be able toincrease their production capacity in Ecuador to 20,000 bpdand fill their initial quota established for the OCP pipeline.

The Sarayacu pump station will be equipped with twoWärtsilä 12V32LN generating sets burning crude oil. Thisorder is a follow-up to the three Wärtsilä 12V32LN unitsPerenco bought last year for the power plant facility at theYuralpa field in Block 21. The gensets will be delivered fourmonths from order.

Wärtsilä 32LN engines have become the technology ofchoice for oil companies needing crude-oil-burning engines togenerate power efficiently. With more than 3000 MW inoperation, onshore and offshore, Wärtsilä has an abundanceof experience in a number of different oil and gas fieldapplications. �

Seven new orders forbioenergy plantsWärtsilä Biopower has gained orders for seven biofuelled energy plants during thefirst few months of 2003. Wärtsilä will supply both complete bioenergy plants andprocess equipment to Sweden, Russia and the Baltic countries. These neworders are an important step in Wärtsilä’s strategy of becoming the first globalsupplier of small-scale biopower plants.

Demand for small power and heating plants for decentralized energyproduction is growing fast and the use of biofuels in electricity generation is risingin Europe.

Plants to SwedenTwo of the new orders are for Sweden. District heating company VilhelminaVärmeverk AB has ordered a 10 MWth process equipment package to meetlocal district heating and sawmill needs.

Tekniska Verken i Linköping AB, a heating utility owned by the city ofLinköping, has placed a turnkey order for a 3 MWth bioenergy plant and a 5 MWth

oil-fired boiler plant to produce energy for the local district heating network.Wärtsilä has previously supplied the same customer with a combined heat andpower plant based on gas-diesel engines.

Bioenergy for Russia and EstoniaThe Finnish-Russian joint venture ZAO Pestovo Novo has ordered a turnkey10 MWth bioenergy plant for the town of Pestovo in the Novgorod region, whereFinnish UPM-Kymmene will supply a sawmill in co-operation with a Russiantimber company.

Wärtsilä has also been contracted to deliver three bioenergy plants to Estonia;two plants for sawmills and one for district heating.

AS Näpi Saeveski, part of Estonia’s largest sawmill company SylvesterGroup, has ordered process equipment for a 6 MWth bioenergy plant inLääne-Virumaa. The new plant, which will replace an old plant, will burn sawmillwaste.

AS Sauga Saeveski has ordered a 6 MWth bioenergy plant for a sawmill inSauga. This plant will produce heat from bark, chippings and sawdust for thesawmill’s drying process. OÜ Pogi has ordered a turnkey 8 MWth bioenergy plantfor the town of Paide.

Lithuania’s firstUAB Sylvester Alytus in Lithuania has ordered a turnkey 8 MWth bioenergyplant for the town of Alytus, Wärtsilä’s first power plant order in Lithuania andtherefore a breakthrough in this market. �

What´s new

As NOX emission limits becomeincreasingly stringent Wärtsilähas successfully tested thecompatibility of selective

catalytic reduction (SCR) with gas anddual-fuel engines for extremely lowemission levels.

Parallel with the first commercial installations of theUltra Low Emissions (ULE) Solution with WärtsiläSG gas engines, Wärtsilä has continueddevelopment of the ULE solution for dual-fuelengines. In a dual-fuel engine, ignition of the leanair-fuel mixture is initiated with injection of a smallamount of LFO as the pilot fuel. The engine canalso be run in pure liquid fuel mode.

During the tests, the compatibility of the SCRsolution with the specific features of the DF enginewere confirmed and further optimized. Apart frompushing the limits for NOX abatement, this wasalso an excellent opportunity to collect extensiveinformation on other emission components andtheir abatement in the selective catalytic reduction(SCR) system.

The near future can be expected to generateprojects where NOX and other emissions need tobe reduced to even lower levels. In these projects,an in-depth knowledge of emission technology willcertainly be a great asset.

SCR TheoryThe catalyst elements in the SCR lower theactivation energy between NOX molecules in theexhaust gas and injected ammonia (NH3).Harmless nitrogen (N2) and water (H2O) are formedas a result of reactions (1) and (2) below.4 NO + 4 NH3 + O2 � 4N2+6 H2O (1)6 NO2 + 8 NH3 � 7 N2 + 12 H2O (2)

Reducing NOX emissions close to zero ppm-vwithout NH3 slip puts high demands on the designof the SCR system:� For the NOX and NH3 molecules to get into

contact with each other, the reagent (NH3)needs to be well mixed with the exhaust gasbefore entering the catalyst.

� The retention time of the reagents in the SCRmust be long enough for all NOX and NH3

molecules to have time to react on the catalystsurface. That is, the catalyst volume needs tobe large enough.

� A delicate balance between the NOX in theexhaust gas and the injected NH3 is needed.Too little NH3 will not allow all NOX to bereduced. Conversely, a surplus of NH3 will leadto emissions of NH3, usually referred to as NH3

slip.Apart from their ability to catalyse the reduction ofNOX, the SCR elements have many otherinteresting properties, including their activitytowards oxidation of higher hydrocarbons. Therealso exist modified SCR elements with additional

properties such as a high activitytowards oxidation of CO and organiccompounds as well as activity towardsoxidation of excess NH3 to harmlessN2.

Test set-upThe test was performed at full scale byupgrading an existing SCR system. TheSCR was installed after a Wärtsilä 32DFengine with an electrical output of5.8 MWe. The upgrading included morethan doubling the catalyst volume andoptimizing the NH3 injection system.

During the test campaign, a NOX

analyser was connected to the SCRcontrol system to enable feedbackcontrol of the NH3 injection. To complywith local CO legislation, the originalSCR system already included an SCRcatalyst layer with enhanced oxidationability.

After the system was upgraded,extensive testing was performed on thefresh catalyst. The measuredcomponents included NOX, NH3,particulate matter, polycyclic aromatichydrocarbons (PAH), hydrocarbons andmore exotic components. Follow-uptesting was performed after one year

(6000 running hours) following a similarmeasurement plan.

During the campaign, SCRperformance was tested with differentsets of catalyst element loading. Itemssuch as pressure drop, control systemperformance, and catalyst performancedrop with time were monitored toensure problem-free long-termoperation in commercial installations.

Test resultsSimultaneous measurements of bothNH3 and NOX verified that it is possibleto achieve both the targeted NOX

emissions and NH3 slip. Figure 1 showsrecorded NOX emissions after the SCRand a calculated 30-minute average.The 30-minute average stayed below5 ppm-v, 15% O2, dry, during themeasurement period.

Simultaneous sampling of NH3

showed that the NH3 slip was wellbelow the targeted 5 ppm-v, at 15%O2, dry. With better settings, especiallyfor the control system, even higherperformance was indicated. Thefollow-up measurements confirmed thesame high performance after one yearof running.

The measurement campaign alsoprovided interesting results for manyother emissions components than NOX

and NH3. This included bothuncontrolled and controlled emissions,thus also indicating the abatementefficiency of these emissions in theSCR. From a long list of test results, theefficient abatement of formaldehyde andPAH in the SCR, as well as theoxidation of NH3 slip in the special SCRelements can be highlighted.

ConclusionsThe R&D project has further verified theSCR design for an Ultra Low EmissionsSolution for gas and dual-fuel engineinstallations. Apart from proving theNOX abatement, the test addedvaluable information on a broad rangeof emissions, both engine emissionsand the effect of the SCR on theseemissions.

The project also provided a lot ofinsight into the critical design issues forlow-emission gas plants and furtherenhances Wärtsilä’s ability to offer gaspower plant solutions for even stricteremission requirements in the future. �

The Power Division launchedits new functionalorganization in January2003. The previous matrix

organization with its variousbusiness units had served itspurpose well but the time wasnow right to focus on thedivision’s overall range ofproducts and services to meetcustomer needs morecompletely.

A new function, Solutions Management,was established that brings marketinformation and product developmentinto a new and closer harmony.

Why Solutions Management?Solutions Management collects andprocesses market information andforecasts, analyses this information, andpasses on the results for continuousdevelopment of new plant solutions andengines. It also contributes to daily

sales activities and customer support.To perform these tasks, the below

Product Groups were set up withinSolutions Management as well as threesupport functions: Market Intelligence,Marketing Communication and OfferingSystems.The Product Groups are:� Power Systems. This consists of two

dedicated product groups: SmallPower Systems and Large PowerSystems. The power ranges are(1-15 MW) and (15-300 MW). Theplants are based on engines burningHFO, LFO and in the Small PowerSystems also gas.

� Large Gas Engine Plants(15-150 MW) based on gas anddual-fuel engines.

� Combined Heat and Power Systems(2-60 MW) incorporating both powergeneration and heat recovery.

� Mechanical Drives based onWärtsilä’s pumping and compressorunits.

Three new Product GroupsWe strongly believe that Wärtsilä canprovide an enlarged portfolio of powergeneration solutions to existing and newcustomers.

Wärtsilä’s traditional plant solutionsare Small and Large Power Systemsfrom 1 to 300 MW operating on gas,LFO and HFO. They are workingextremely well and represent the bulk ofWärtsilä’s annual power plant deliveries,on average over 1700 MW per year,Figure 1.

However, we are now in a position tointroduce three new focused solutionswith state-of-the-art plant and enginetechnologies in power sectors whereWärtsilä has so far not had a significantpresence.

Large Gas Plants are aimed at theutility market that has traditionally beenthe domain of gas turbines. CombinedHeat and Power systems will provideoptimal management of heat loads

according to customer needs, whileMechanical Drives takes Wärtsilä closerto the big oil and gas companiesworldwide with a broader scope ofproven products and technology.

Large Gas PlantsA few years ago the biggest gasengines on the market had unit outputsof 5.5 MW. Today Wärtsilä reciprocatinggas engines offer a net plant electricalefficiency of over 46% in single cycleand unit sizes up to 16 MW. Based onthese units, the plant sizes can easily belarger than 150 MW.

References are accumulating welland we are now ready to install theseengines in really large plants. Thebiggest Wärtsilä gas plant in operationso far has an output of more than110 MW.

These plant concepts enable us tocompete effectively against the maindisadvantages of gas turbines today:low single-cycle efficiency, power and

heat rate derating at high temperaturesand altitudes, and ageing turbine rotors,Figure 2.

Combined Heat and PowerWhere there is a captive heat load or adistrict heating network close by, thereis often a striking opportunity to build aCHP system into the plant design forgreater profitability.

Wärtsilä power plants withreciprocating engine technology aremore suitable than traditional gasturbine technologies for hot waterproduction. This team are also expertsin providing solutions for combinedcycle plants where maximized electricitygeneration is the aim.

Mechanical DrivesThe first Wärtsilä pumping units in thefield today are running on heavy crudeoil. Our two major pumping orders,OCP in Ecuador and BTC in Turkey,each have more than 100 MW of total

installed power.The world’s first 5000 - 10,000 hp

class of separable reciprocatingcompressor sets have to date operatedfor 10,000 hours with excellent results.Major benefits experienced by the oiland gas companies from theseproducts are their reliable heavy crudeoil running capabilities and the large gasengine units’ high efficiency, Figure 3.

The future is distributed powerThe world power market is movingtowards distributed power generation.This also means increasingly diversifiedcustomer needs.

To meet these demands Wärtsilä isnow launching focused Product Groupsbased on its already proven plant andengine technologies. Wärtsilä’s broadspectrum of long-standing customerswill shape the continuous developmentof Solutions Management. �

At Wärtsilä we have alwaysunderstood this statement tobe inherently true: if we satisfyour customers, they will gladly

return to us with more business, orrecommend us to others. In today’sbusiness climate, this has neverbeen more true. Repeat business, orbusiness generated fromrecommendations, is an importantsales opportunity for us.

In the United States, Wärtsilä NorthAmerica Inc. have recognized theimportance of enhanced customersatisfaction, and made decisive moves tonot only meet, but exceed customers’needs. In order to meet and exceed, thefirst step was to listen and acknowledgewhat customers were looking for – in thisrespect, Wärtsilä North America has formeda customer user’s group, called theCustomer OpEx Forum.

Customer OpEx Forum:a users’ groupThe Customer Operative Excellence Forum(Customer OpEx Forum) was formed in2002 specifically to help US gas enginecustomers interact with Wärtsilä and witheach other to optimize the operations oftheir gas engine power plants. It began insummer 2002 with a team of Wärtsiläspecialists touring several of the plants, andwith a Customer Satisfaction survey of allgas power plants in which the customers

informed Wärtsilä of their impressions ofour technology and way of working.

The first Customer OpEx Forum washeld in November 2002. Frank Donnelly,Vice President of Power Plants for WärtsiläNorth America, outlined the goals of thisOpEx Forum:� Improved relationships between Wärtsilä

and its customers� More efficient feedback and response� Learning new ways to operate our plants

efficiently and profitably� Successful operations� Expanded opportunitiesAt this OpEx forum, Wärtsilä was able toget direct feedback from the participantsand to inform about actions taken or to betaken in response to the feedback. Othertopics of the OpEx Forum includedtroubleshooting training, optimizingreliability, employing ‘tricks of the trade’,remote monitoring, technology update andapplication overview.

In an informal discussion format, theparticipants gave further input actionsneeded to increase communicationbetween all the parties, in an effort toenhance the experience the customershave in dealing with Wärtsilä.

Overall, the Customer OpEx Forum was aresounding success. Customers havereported improved interaction on site withWärtsilä employees. They have also seenincreased documentation of site visits and arelooking forward to even more improvementsto be made on a go-forward basis.

In a follow-up meeting to discuss globalissues this February in Fort Lauderdale,Florida, a representative from TGP (a gascompression plant with six Wärtsilä18V34SG-CD engines) said, “This is a goodstart. The OpEx Forum has already begunto make a difference in how we worktogether. Today it’s easier for us to keep upwith what Wärtsilä is doing, and how it’sgoing to help us, and that’s making ourguys a lot happier.”

Delivering satisfactionSo, what are the results of this firstCustomer OpEx Forum?

For one, there is improveddocumentation of site visits, which hasbeen noted and appreciated by theoperators of Wärtsilä plants. A policy wasenacted in which a satisfaction surveyquestionnaire is now enclosed in all servicereports submitted to the customer.

Regular teleconferencing meetingsbetween Wärtsilä and customers haveproven very effective in resolvingoutstanding site issues.

A website has been set up forcustomers to post discussions on plantoperations, to retrieve the latest servicebulletins and product upgrades, and to findout the latest Wärtsilä news. The feedbackon this website has been very positive todate, and has served as a ‘virtual meetingplace’ for Wärtsilä customers to postquestions about the operations of theirplants.


Optimizing performance

Satisfying our customersis the key to our success

by Kelly SpeakesBusiness Development ManagerWärtsilä North America Inc.

A number of technical issues werediscussed during the OpEx Forum. Withactive information sharing and interactionbetween the participants, many of theissues were addressed there and then. Onsome issues, further action programs wereagreed with active participation by bothWärtsilä and its customers.

One WärtsiläIn February 2003 a group of Wärtsiläemployees took two days to assess thework done in response to customers’needs, what remains to be done, and howthis will be accomplished. An importantrealization from the meeting is that theachievement of a high level of customersatisfaction will drive increased employeesatisfaction and create shareholder value.

The Customer OpEx Forum in theUnited Sates has set itself a specific target– to increase the satisfaction level of its UScustomers. This is accomplished throughincreased employee satisfaction, andthrough meeting and exceeding thecustomers’ needs.

Although the Customer OpEx Forum istoday focused on the US market, the goalsand directives for customer satisfaction areindeed global. One Wärtsilä, one that actsboth cross-divisionally andcross-continentally, will make thedifference between a good company andan excellent one. �


Two Wärtsilä BioPower plantsto Finnforest sawmills

Wärtsilä is to supply two biopowerplants for combined heat andpower production to FinnforestCorporation’s Vilppula and Renko

sawmills. Finnforest Corporation is Europe’sbiggest wood group.

Finnforest’s Vilppula sawmill is the largestin Europe. At the Vilppula sawmill, Wärtsiläwill build a BioPower 5 plant which willproduce electricity and heat, as well as aBioEnergy plant producing heat only. Theelectrical output of both plants is 2.9 MWand the total heat output is 22.5 MW.Together these plants will produce over70% of the electricity needed and 100% ofthe heat needed to dry wood at the sawmill,and they will also provide all the heatrequired for the town of Vilppula.

The plant at the Renko sawmill, aBioPower 2, will be smaller in scale, with1.3 MW electrical output and 8 MW heatoutput. It will produce the majority of theheat needed for the drying processes at thesawmill and approximately 50% of theelectricity required by the sawmill.

The fuel used at Vilppula and Renko willbe byproducts of the sawing process,primarily bark and sawdust. The powerplants will be operational during the currentyear.

These new plants represent Wärtsilä’sown modularized BioPower concept andare a breakthrough for this type of productin Finland. Other important markets forthese products besides Finland and the EUare North America and certain LatinAmerican countries.

BioGrate for wet biomassCo-operation between Wärtsilä andFinnforest dates back to 1994, when thefirst plant was delivered to Soinlahti – thiswas also the first bioenergy plant deliveredwith BioGrate technology.

Today all Wärtsilä bioplants use thispatented combustion technology, which is

especially suitable for burning extremely wetwood residues, wood chips, bark andsawdust. Since the Soinlahti project, Wärtsilähas delivered five more bioenergy plants toFinnforest’s sawmills for producing heat forthe drying process.

These new projects are an important stepin both Wärtsilä’s and Finnforest’s goal ofdeveloping environmentally sound solutions.Finnforest’s policy is to ensure that itsproducts and manufacturing processes arein harmony with the principle of sustainabledevelopment.

A winning concept“When it became necessary to resolve thequestion of energy generation at our Vilppulaand Renko sawmills, we considered anumber of alternatives,” says MarkkuKauppinen, Technical Director of FinnforestCorporation.

“Our decision was supported by the statesubsidy provided by the Ministry of Tradeand Industry for biopower plants, coupledwith Wärtsilä’s biopower concept based oncombined heat and power. Building suchplants is now an economically feasible optionand it also supports the principle ofsustainable development.”

FinnforestFinnforest Corporation, owned by theMetsäliitto Group, is Europe’s biggest woodgroup with net sales of EUR 1.8 billion.Finnforest offers product and servicepackages based on wood to its customersin construction, industry, distribution and theretail sector.

Operations are grouped into two industrialdivisions: solid wood and engineered wood.Finnforest operates in over 20 countries.Scandinavian operations are theresponsibility of the Norwegian subsidiaryMoelven. Finnforest employs over 7700people. �

What´s new

Today’s power supply situation inHungary is very similar to that ofthe rest of the European Unionsince the country’s UCTE power

system is linked with other EUcountries. Around 40% of the country’senergy is produced by four 440 MWnuclear power plant units today, while afurther 30% is based on gas and lignite.

However, the largest built-in capacityis based on gas, namely gas boilers andgas turbines, for system load controllingpurposes. Since 1999, the Hungariangas engine business has grown to morethan 100 units with an average capacityof 1 MW being installed.

Demand for cogenerationThere are currently no large power plantinvestments in Hungary; marketderegulation came into effect this yearat a time when overcapacity is not yet aproblem in Hungary. This has madeopportunities in the region scarce andinvestors regard the situation inHungary as low priority.

A decentralized cogeneration plantwith an average monthly efficiency of65% has the potential to generateelectricity that can be sold at65 €/MWh. Gas purchase prices arestill under regulation and are kept at alow level of 15 €/MWh on average. Thismeans that cogeneration units are

booming in the country, in order toupgrade the old district heating system.

The power market in Hungary isforecast to slow down due to marketderegulation, a lack of incentives forinvestors and low gas prices. Closuresof some old plants are expected,however, if these plants are replacedwith the viable option of GTCC (gasturbine combined-cycle) or gas engineplants, the small-scale installationscould be operated by local engineers.

Hungarian district heating utilities areexpanding their commercial activities intoelectricity production. This new businessmove will produce extra income for theutilities from the sale of electricity toHungary’s national grid. This has beenbrought about by recent Hungarianlegislation, which enables a districtheating company to sell electricity below20 MW to the national grid.

Three power plant contractsWärtsilä was awarded three power plantcontracts by Hungarian district heatingcompanies in 2002 following toughinternational competition. These areWärtsilä’s first significant power plantprojects in Hungary. The contractawards were based on the high electricalefficiency of Wärtsilä’s engines.

For the first two contracts, SinergyKft, one of Hungary’s leading

investment companies, chose Wärtsiläto supply engines for two new powerplants in Kazincbarcika andTiszaújváros. The plants use three18V220SG gas engines atKazincbarcika and two 18V220SG gasengines at Tiszaújváros, with 3.2 MWe

power per unit to generate electricity.The engines were supplied to the

sites in April 2002 and the plantsbegan commercial operation duringSeptember of the same year. Wärtsiläand Sinergy also made a 10-yearmaintenance agreement.

Medium-speed enginesoffer decisive benefitsIn the third contract, Gy �orh �o DistrictHeating Company, which supplies heatto the City of Gy �or,chose Wärtsilä tosupply engines for its new power plant.The installation utilizes two 18V34SGgas engines to produce a heat output of10,920 kWth and electrical output of12,000 kWe.

The engines were supplied to the sitein the summer of 2002 and the powerplant was fully operational in October2002. This contract award also includesa 10-year maintenance contract.

The main reason for the choice ofWärtsilä was the very high efficiency ofthe Wärtsilä medium-speed enginescompared to a high-speed solution.



Focus on Hungary:providing energy and service

by Pilot Communications

This also meant that fewer engine unitswere required for the necessary output,which reduced the plant’s constructioncost and considerably speeded up theconstruction time. In the client’s opinionthe lower engine speed also makes forlonger component lifetimes.

The plant was engineered, supplied,built and started up in close teamworkinvolving Gy �orh �o, Wärtsilä and thecontractors. Commenting on theWärtsilä solution, the client specificallysingled out the careful design of thecomplex heat recovery automationsystem, which contributed significantly

to the plant’s rapid commissioning.All in all the customer is very satisfied

with the installation and has ordered athird engine which should be inoperation in October 2003.

Maintenance supportAs well as quick construction, bothSinergy Kft and Gy �orh �o District HeatingCompany requested 10-yearmaintenance contracts and training fortheir power plant operators andengineers. This was because thetechnology was fairly complex and theengine sizes were unlike any otherinstallations in Hungary at the time.

Typically, Wärtsilä maintenancecontracts in Hungary will cover allaspects of a plant’s maintenanceincluding: complete project mobilization,preventive & predictive maintenanceplanning, project planning, plantperformance, efficiency monitoring,safety compliance, integrated logisticssupport and inventory management.Complete plant and technical training,

assessments and reporting allcontribute to allow the customer to seethe economic and technical value of aWärtsilä Service contract.

Market favours smallpower plantsHungary in the future is unlikely to seebig changes in the way power isproduced although it is likely that allinstallations will be decentralized withinthe next few years.

Hungary currently imports gas fromRussia using the only existing pipelinebetween the two countries, and gas willstill remain the primary fuel used inHungary. With little change forecast,large power plant contracts are unlikelyto materialize from Hungary. Wärtsilä,however, is well placed to increase itsmarket share in the country due to itsproven fast-track construction methodsand because the majority of new powerplant owners are opting formaintenance agreements. �

Wärtsilä Power Modulesprove their worth

Awash and Kaliti, Ethiopia:14 Power ModulesOn 19 December 2002 Wärtsilä won thecontract to supply two turnkey installations ofemergency diesel generating sets to locationsin Ethiopia. The order also marked the largestfor Wärtsilä’s Power Modules so far.

The customer, state-owned utilitycompany Ethiopian Electric PowerCorporation (EEPCO), was created for thepurpose of generating, transmitting, anddistributing electricity in Ethiopia. It hasrequested power plants in Awash and Kaliti,both high-altitude locations at 900 m and2500 m respectively.

The Awash site will utilize ten 18V200Wärtsilä Power Modules to achieve an outputof 35 MWe at a heat-rate of 9122 kJ/kWh.The Kaliti plant will comprise four 18V200Wärtsilä Power Modules, producing 10 MWe

at a heat-rate of 9414 kJ/kWh. Both sites willoperate on light fuel oil and the powerproduced will be distributed to theInterconnected System’s substation. Theengines will be manufactured at Wärtsilä’sfactory in Mulhouse, France.

EEPCO was impressed with Wärtsilä’sstrong existing relationships with otherprojects, its attractively priced Power Moduleconcept and fast-track delivery time. Wärtsiläwas the only bidder to comply with therequested fast-track schedule.

In turn, EEPCO was keen to branch outfrom hydropower, which makes up 95% of itstotal output. The remote location of theAwash site combined with the severe droughtand unpredictable weather, has meant thatthe customer is now optimizing theirgeneration capacity with thermal rather thanhydroplants. This will enable EEPCO to havea more balanced generation mix and therebyprovide more reliable power to its customers.It currently operates two electrical supplysystems – the main Interconnected Systemand a number of self-contained systems –with a total installed capacity of 500 MW.

The Power Module emergency generatingsets will be in commercial operation in 4.5months after the commencement date. �

Wärtsilä's Power Module concept is proving ever more popular,particularly in remote regions where new power is urgently needed, thepower supply is unreliable or building a conventional power station isprohibitively expensive. Wärtsilä Power Modules, designed for fast-track

implementation of 2-40 MW plant outputs, mark the latest development inefficient, distributed power generation. Three recent orders clearly illustratethe concept's success.


Bicentenario in northern Chile:three Power ModulesWärstilä has solved a shortage of electricalpower for the city of Calama.The city’s localutility, GasRed S.A., ordered a completegas-fuelled power plant from Wärtsilä inOctober 2002. The project includes thesupply, erection and startup of threeWärtsilä Power Module units, each with18V220SG engines. The plant is expectedto be operational by mid-2004.

Called Bicentenario, the plant will serveas a peaking plant for Calama, which liessome 1500 km north of Chile’s capital,Santiago, and 2300 metres above sea level.Calama is in the middle of the world’s mostarid desert, the Atacama, and lies close toChuquicamata, the world’s largest open pitcopper mine. Weather conditions aresevere in that region with very lowtemperatures in winter and a scorching dryheat in summer. This, added to constantdust and sand clouds in the afternoons,subjects all equipment in the area to theharshest conditions.

Growth in Chile’s mining industry hasbrought about the relocation of the miningtown of Chuquicamata, with 25,000

inhabitants, to the city of Calama, due tothe adverse environmental conditions. Thishas meant heavy growth in constructionand renovation and, of course, an increasein electric power consumption. This is mostevident during peak hours, whenconsumption is three times higher thanduring ‘normal’ hours, which is puttingpower transmission from the grid system toCalama under pressure.

Power guaranteed, scalabilityensuredThese power generation and environmentalconditions highlight the advantages ofWärtsilä Power Module technology. Thefirst objective of the Bicentenario plant willbe to generate electricity during periods ofhigh demand. The plant will be used fivehours daily during 365 days in its first yearof operation. When the residential areas of‘New Calama’ start to become occupied,this power generation period will beextended.

The land lots owned by GasRed arelocated on the city’s outskirts but relatively

close to the city’s water supply. Despite theinitial opposition to the new plant from theenvironmental authority, the necessarypermits were in fact obtained in record timethanks to the low emission levels of theWärtsilä 18V220SG engines.

Variability in the expected demand andgrowth was an important factor whenselecting the supplier for the plant. TheWärtsilä solution allows GasRed to easilyprovide the power needed without anylosses in engine efficiency, as well as themuch needed scalability in the future.

The plant will play an important role inthe community in the future as it will act asan alternative guaranteed power supply,which the city does not have at themoment, providing electricity even duringgrid black-outs.

Lastly, the technological features of theWOIS (Wärtsilä Operation Interface System)will permit the operation of the BicentenarioPlant to be monitored in real time fromMejillones, 200 km west on the coast, andfrom Santiago by means of GasRed’ssatellite link. �

Vieques, the Caribbean:two Power ModulesOn 25 January 2003 Wärtsilä won thecontract to supply two Power Modules tothe island of Vieques, near Puerto Rico.The customer and prime contractor isPuerto Rican company RG Engineering,and the end user will be Prepa – thesecond largest publicly-owned utility USA.

This crucial power plant, in a regionprone to hurricanes, will be a reliable powersource in case of emergency for the islandof Vieques, which is located off PuertoRico’s eastern shore.

Prepa requested that the power plantcould run as a baseload facility if needed. APower Module was considered moreappropriate than a traditional power plant,as it is easier to install in remote locationssuch as Vieques.

The Power Module is designed toensure easy plant operation andmaintenance in continuous use and themodular nature of the plant will enable it toreadily accept a third unit. Wärtsilä’sversatility and understanding of customers

needs allowed the team to provide a bidthat was both competitively priced and infull compliance with Prepa’s demandingtechnical requirements.

Each of the two Power Modules is apre-assembled, self-contained unitcontaining a 3.3 MW, 18V200 dieselgenerator set and auxiliaries. Together withthe electrical module containing the controlroom and the medium-voltage substation,this forms a complete power plant that canbe installed or relocated in a very shorttime.

Wärtsilä’s part of the contract willinclude equipment delivery, installationsupervision and commissioning, while RGEngineering will perform the balance of theproject: site preparation works, fuelstorage, high-voltage substation andtransmission lines.

December 2003 is the scheduleddelivery date. The construction site wasinaugurated in the presence of the PrepaExecutive Director, CPA Hector Rosario,

on 24 January 2003.Wärtsilä’s objectives are to deliver a

quality power plant on time, which can beextended with a third unit, and to ensure theplant receives optimum service and partssupport. �

Wärtsilä’s high-output gasengines, and the newCentrifugal Driveconcept, now give the

US gas transmission industry atrue alternative to turbines byapplying the inherent benefits ofa reciprocating engine over agas turbine. Wärtsilä hasconsiderable experience in thisfield on which to build apromising future.Entering a completely new market isnever an easy task. The processproduces many seemingly simplequestions that need answers. How bigis the market? How is it segmented?Where do we fit in? What productsshould we focus on? What is thecompetition? What does Wärtsilä haveto do to make a place for itself in themarket?

Since making the decision to enterthe North American gas compressionmarket in 1996, Wärtsilä has addressedthese and many other questions as ithas built a solid foundation for futuregrowth.

Our successes to date include:� Seven solid reference installations in

our two target market segments

(storage and transmission) that havenow accumulated close to 40,000running hours.

� Becoming a Full Member of the GasMachinery Research Council, themost widely recognized andrespected industry association inNorth America.

� Expanding the 34 SG compressionproduct offerings to include the12V,18V and 20V configurations so thatwe now cover a power range from5500 - 10,700 hp (4140-8000 kW).

Industry fundamentalsIt is no secret that the energy businessin the United States is currentlyexperiencing many challenges broughton mainly by the effects of the Enronscandal and the weak economy. Thishas definitely had an impact on the gascompression business. While the gaspipelines and storage business units ofour main customers are financially quitehealthy on their own, the profits thatwould normally be used for capitalprojects are instead being directed tothe corporate balance sheets toimprove the share price and to reducedebt load.

While this situation presents a

challenge for sales, anyone who hasbeen involved with the oil and gasbusiness for any significant time knowsthat the business is cyclical in natureand that business conditions willimprove.

Aside from the technical marketaspects, consider the following industryfundamentals:� Approximately 80% of the gas

transmission compressioninfrastructure in North America isover 40 years old. It is in use everyday and at some time will bereplaced.

� Most of this old infrastructurecomprises relatively small units of1000 - 1500 hp (750-1100 kW) withhigh heat rates of 8000-9000BTU/hph (11,000-13,000 kJ/kWh).

� There are clear benefits in replacingthis equipment with larger Wärtsiläunits of 5000-10,000 hp and heatrate of 5800 BTU/hph(8000 kJ/kWh).

� Fuel efficiency and operationalflexibility are becoming veryimportant factors in the equipmentselection process owing tocompetition from other pipelines andsimple economics.


Gas compression in North America:solid history, poised for the future

byBill Amundsen, Business Development ManagerWärtsilä North America Inc.

and Paul Glandt, General ManagerCentral Service OperationsWärtsilä North America Inc

Inside view

� In their quest to reduce costs, endusers are increasingly outsourcingmore functions such as plantengineering, procurement andconstruction. With a solidbackground in turnkey power plants,Wärtsilä is well positioned to expandinto turnkey compression stations.

Service and communicationWärtsilä’s focus now is on four keyareas. These are:(1) active pursuit of the available capitalprojects in the target markets(2) providing service support to existingplants(3) expanding our product offerings tothe market, and(4) expanding co-operation withengineering companies involved incompressor station EPC work.

There is an old saying that “Salesperforms the wedding ceremony, butService makes the marriage work”. Thishas certainly been true in the case ofour compression customers. Servicestarted from a position of having only abasic knowledge of the uniquecustomer needs in this business andhas developed an excellent relationship

with the customers and supported themwell.

As expected in any new market,service support was an initial questionmark with customers. Through the hardwork and dedication of the WärtsiläNorth America Service Team, questionsby customers have been replaced by afeeling of assurance that they will getthe support that they need when theyneed it.

Wärtsilä’s service team hasleveraged technology and transferredknow-how to its local regional officesthat provide the support needed by thecompression industry. These officeswere established many years ago fordirect after-sales support to the marineand power industries. Today theysupport the compression industry withnot only the classic heavy equipmentservice that we are familiar with; theyalso utilize a refreshing set of new toolsthat permit customers to tailor theirlifecycle support to their specific needs.This support includes both theequipment and the qualifying of thecustomer’s employees on the newtechnology.

Wärtsilä realizes the importance of

having strong communication links withits customers and the industry.Communication provides the catalyst tomeet the industry’s ever-changingrequirements. To enhancecommunication, includingcommunication between the equipmentusers, Wärtsilä has established acustomer forum called OperationExcellence (OpEx). This forum, and theshared website which it supports, hasallowed Wärtsilä to further improve itsresponsiveness to customer needs (seepages 18-19).

Centrifugal drivesProduct expansion has included not

only introducing new engine cylinderconfigurations, but also initiating newapplications to expand our possibilities.The best example of this is theCentrifugal Drive Initiative. By forming ateam consisting of representatives fromVoith Turbo Transmission andDresser-Rand and a large customer,Wärtsilä has led the way in developingthe idea of driving a centrifugalcompressor with a reciprocating engine.

Until the advent of the high-output34SG line, there was virtually no otheralternative to gas turbines when the jobindicated a need for a gas engine driverover 5000 hp (3800 kW). The Wärtsiläconcept applies the inherent benefits ofa reciprocating engine over a gasturbine and now gives the transmissionindustry a true alternative to turbines. Ithas been received well by industry endusers and will be featured at the 2003Gas Machinery Conference in October.Steps are underway to begin preliminaryengineering on the concept so that wecan respond quickly when theopportunity arises.

Finally, now that the main end usersare aware of Wärtsilä and our products,we are spending more time marketingto the engineering companies thatperform compressor station design andconstruction services for the end users.

As the process from feasibility studyto commissioning of new compressioninfrastructure typically takes 3-4 years,our goal is to make the engineeringcompanies aware of our capabilities tohelp ensure that Wärtsilä is consideredas an option during the early stages of aproject when the basic decisions aboutequipment selection are normally made.

In summary, Wärtsilä’s pastsuccesses give us a solid foundationfrom which to build on. Together withour current focus points, they give us anexcellent reason to look forward to avery positive future. �


What’s new......on landEstrella del Norte turns 100,000running hoursOn 1 September 2002 Estrella delNorte’s ‘Engine #5’ in the DominicanRepublic passed 100,000 runninghours. On 19 January 1990, sometwelve years ago, ‘Engine #5’ wasstarted for the first time in commercialoperation. Estrella del Norte, with 9 x18V32 engines, was Wärtsilä’s very firstdelivery of a floating baseload powerplant. The next issue of Energy Newswill feature this successful project inmore detail.

Wärtsilä Power Plant QualityAward for the Kipevu projectWärtsilä Power Plants has awarded theinternal quality award for 2002 to theproject team executing the 74 MWKipevu project in Kenya. The projectwas started up in September 2001,right on time and is today Kenya Powerand Lighting Co. Ltd’s lowest-costenergy producer.

“The project team, developer and theoperation manager are a fine exampleof how Wärtsilä and its customers canwork together for their mutual benefitand how operational quality can beachieved through good co-operationbetween different units and divisions,”noted Quality Manager Niklas Åberg.

The award was accepted by theproject team: Timo Mäntysalo, MikaKoivulahti, Keijo Lehtonen, AndersNystrand, Sebastian Mellberg, KjellNord and Pieter Hokkeling.

Accepting the award on behalf ofVacon were Vacon’s President, VesaLaisi, and Executive Vice President ErkkiRaunio.

Wärtsilä strengthens enginedevelopment testingIn recent years Wärtsilä has placedincreasing focus on research inemission technology and developingwell-proven products with the highestreliability. The capacity supporting thisdevelopment has been good but notalways sufficient. Therefore, WärtsiläFinland Oy has now taken completeownership of Wasa Pilot Power PlantOy (WPPP) in Vaasa, Finland at the startof the year. The previous co-ownerswere Alstom Finland Oy and two localelectricity utilities in the Vaasa region.

Since WPPP’s priority until now hasbeen to optimize electricity and heatproduction for the local grid and districtheating network, Wärtsilä had onlylimited opportunity to perform testactivities. The new ownership structure,

where WPPP is an integrated part of theEngine division’s technology unit inFinland, allows increased focus onresearch and development.

...at seaWärtsilä tests first Wärtsilä 50DFdual-fuel engine and organizesCustomer DayWärtsilä successfully completed thefactory acceptance test of the firstWärtsilä 50DF engine in a series of fourdual-fuel engines for a 74,000 m3 LNGcarrier. The vessel is under constructionat the French shipyard Chantiers del’Atlantique for the French gas holdingcompany Gaz de France. Due fordelivery in 2004, it will be powered byfour Wärtsilä 6L50DF dual-fuel enginegenerating sets which will meet all theship’s propulsion and shipboardelectrical requirements.

A Customer Day was organized inVaasa on 9 January 2003 to witness thetest run. Around 16 customers fromFrance, UK, USA, Norway, Sweden andJapan gathered in the Wärtsilälaboratory to see the engine on the testbed and witness the test run. First theengine was started to run on gas andthen it was tripped over to diesel andthen once again transferred back togas. The test run was successfullyconducted by Mr Peter Örn, Supervisorof Gas Testing, and Mr Anders Åberg,Test Run Manager. The event wasfavourably received. “Very impressive.This is a real treat to see the enginerunning,” commented Mr Jan Flatsethfrom Bergesen D.Y., Norway.
