Energy Concept

• Protection of environment and resources

• Rational und economical handling of energy

• Secure, convenient and demand controlled supply

• Social compatibility and satisfied costumers

• Economy and competitiveness

• Self-obligation to reduce CO –Emissions

• district heat development• increased efficiency of power stations• thermal insulation in buildings • development of public transport.

Climate Protection Program (KLiP)

2

Success of KLiP

• Avoidance of a total of two million tons of CO2 emissions annually

• Between 1990 and 2002 annual CO2 emissions in Vienna were reduced by 3 % to approximately 6.3 million tons

• equivalent of 4 tons of CO2 per capita.

Energy efficiency program (SEP)

• Improvement of energy efficieny in Vienna

• Reduction of climate gases• Reduction of dependence on

imports• Contribution to security of

supply• Contribution to awareness

raising of relevant persons• Public awareness raising for

energy saving

SEP-References to District Heating

• Further development of district heating

• Greening of district heating

• District cooling

Developments in DH

• Biomass plant (37 MWth)• Third waste incineration

plant (54 MWth)• Geothermal plant for

regional development area (15 MWth)

• CHP repowering Simmering ½ (170 MWth)

DH Market

TodayMarket share 35%

5.290 GWh Heat sold

2020 expected market share > 50%

7.500 GWh heat sold

Growth based mainly on renewables and waste heat!

Efficiency Measures in DH

• Additional mesh in the network + 100 MW useable

• Heat storage facility for district heating+ 170 MW usable

Low CO2 Emissions

Calculation from federal environmental agency

Includes also CO2 from waste incineration

Expected Results

• Reduction of ~ 2,7 million MWh fossil fuelsSaves about € 53 millions energy import

• 38% reduction of CO2 emissions for domestic use11% reduction of CO2 emissions for waste treatment

• + 8600 GWh electricity produced in CHP-mode~ 1/3 of Austrian thermal electricity production

• + 100% waste recycling in Vienna (energetic and material)

• + 100% of industrial waste heat in the area is used
