Turano Lodigiano 1 x 800 MWCombined Cycle

Power Plant

Scheda Turano Lodigiano_AW:lodi 10/05/11 11:47 Pagina 1

The Turano Lodigiano/Bertonico power plant, situatednear Lodi in northern Italy, is owned by Sorgenia S.p.A.,an important private operator on the Italian market forelectric power and natural gas, with a strong focus onrespect for the environment and clean energy.The plant is located in a recently reclaimed industrialarea that was previously occupied by a refinery demoli-shed in the early 1980s, and there are plans to re-qualifythe surrounding area by developing industrial and arti-san sites nearby. In April 2008 Ansaldo Energia was awarded the EPC con-tract to build the power plant on a turnkey basis and aLong Term Service Agreement (LTSA) to maintain the 2gas turbines and relative generators. In 2009 the custo-mer, based in part on positive experience gained at Tu-rano, awarded Ansaldo Energia a similar contract for thesister plant in Aprilia (Province of Latina). The power plant comprises a combined cycle with twogas turbines and one steam turbine (2+1 configuration),delivering a nominal output of 800 MW.The work assigned to Ansaldo Energia as EPC Contrac-tor included the design, supply, on-site installation, start-up and testing of the entire power plant, comprising themain components in the power block.The turnkey supply of which Ansaldo Energia is in chargealso covers the gas station, the thermal cycle, the auxi-liary systems, including one auxiliary boiler and a waterdemineralisation and recover plant (ZLD), the HV, MV

and LV electrical equipment, including one metal-cladgas insulated switchgear (GIS) for connection to theTerna substation, the plant automation system (DCS)and the design and implementation of civil works for theentire plant. Third parties commissioned directly by thecustomer developed the natural gas feeding system andthe high voltage electric substation.The distinctive features of the project are its focus onenvironmental issues and excellent operating flexibility,which are critical success factors for power producerstoday, who are faced with an ever more competitive mar-ket and a society increasingly aware of environmentalproblems. A combined cycle solution plus Ansaldo Ener-gia technology delivers excellent plant performance withlow atmospheric emission impact. The class 4 AE94.3Agas turbine with VeLoNOx burners has been succes-sfully tested on other power plants and the base load ef-ficiency measured during testing was higher than 57%,with CO and NOx emissions much lower than 30 mg/Nm3.The results of plant efficiency tests at partial load wereequally satisfactory. The management of water resourceswas also a key focus and the plant has a Zero Liquid Di-scharge (ZLD) water treatment system that reduces theinput of process water from wells, as well as a powerfulair condenser used to condense the steam without re-sorting to external water resources for cooling. Although the power plant is situated in an industrial areaaway from population settlements, the design meets

Turano Lodigiano 1 x 800 MWCombined Cycle Power Plant


specific architectural requirements to ensure environ-mental and landscape integration in such a way as toreduce visual and acoustic impact. The buildings areclad in panels that insulate from and absorb sound,which represent one of the main visual features of theplant, along with the big hexagonal concrete stack about100 m high and the brick red colour used for variousplant sections, recalling the natural colours of the areasurrounding the plant. So far as power generation is con-cerned, the plant has been designed to meet the voltageand frequency regulation requirements of the Italiantransmission network as stipulated by Terna (the ItalianNational Grid operator), while on a functional level theplant has been designed to deliver maximum operatingflexibility in accordance with legal atmospheric pollutantemission criteria. The customer can vary load on a dailybasis in peak hours and during the weekend. Rapidplant start up allows the customer to begin generatingpower quickly, as well as to operate with different plantconfigurations and variable loads, providing a rapid andflexible response to network demand.The project was given the Notice to Proceed by the cu-stomer in April 2008 and construction work began in Fe-bruary 2009. A constant focus on the real needs of thecustomer and the climate of proactive collaborationestablished, together with technical expertise and care-ful planning and monitoring of work, have made it pos-sible to achieve the general project objectives and,

specifically, plant delivery (PAC issued by customer Sor-genia) in just 30 months from the NTP. Site work (civilworks, electromechanical assembly, start-up activitiesand testing) involved up to about 850 people on site inpeak periods and was performed in such a way as to en-sure the health and safety of both its own workers, andthose of associated companies and sub-contractorsworking on site. With the final hand-over of the plant to the customer,planned for November 2010, the Long Term ServiceAgreement covering maintenance will come into effect. Under the terms of this contract Ansaldo Energia is com-mitted for 7+7 years to managing and performing rou-tine maintenance and repair work on the 2 gas turbinesets, undertaking to maintain performance values withminimum deterioration and high turbo generator availa-bility values for the entire duration of the contract. The agreement also entails operating parameter loggingand remote monitoring 24/7 from the diagnostic controlroom at Ansaldo Energias Genoa production facility.

N. 1 Gas Turbine Hot Gas Path Inspection

N. 4 Generator Major Overall

N. 5 Steam Turbine minor inspection (valve inspection)

N. 24 minor inspection of gas turbine and generator

Obtaining excellent performance both in term of ou-tage period and machine setting, gaining the Clientsappreciation, having often exceeded the availability tar-get guaranteed in the Contract. During the LTSA period Ansaldo Energia proposed toEnipower several upgrading and TILs with the aim toimprove power output, flexibility, reliability and to re-duce emissions.The main improvements ordered by Enipower and im-plemented by Ansaldo Energia in Ferrera Erbognonepower plant were:

CMF+: Compressor mass flow increase for power increase

Main characteristicsPlant main featuresServola combined cycle power plant is a 1+1 configurationwith sea water surface condenser for electrical and thermalenergy production. The main feature to highlight of thisplant is that it is designed to fire waste gas from steel in-dustry such as BFG (blast-furnace gas) and COG (coke-ovengas). These two fuels are burnt into the combustion cham-ber of the gas turbine together with natural gas. The BFG flow is of about 112000 Nm3/h and the COG flowis of about 19000 Nm3/h. The system is equipped with agas turbine model dedicated to this application with twocompressors on its axial line.Thanks to the solution adoptedthis plant has a CIP6 certification. Finally the plant candischarge industrial steam for cogeneration use. The most important benefit is the use, as fuel, of wastegas from steel industry, mixed with natural gas.
