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

Waste utilisation

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
