Viennas Sustainable Energy Policy Climate Protection and Energy

Vienna's Sustainable Energy Policy Climate Protection and Energy Efficiency Dipl. -Ing. Dr. Edgar Hauer City of Vienna

Sustainable Energy Community Ø Energy-Concept Ø Climate protection program (KLi. P) Ø Communal energy efficiency program (SEP)

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

Climate Protection Program (KLi. P) • Self-obligation to reduce CO 2–Emissions • • district heat development increased efficiency of power stations thermal insulation in buildings development of public transport.

Success of KLi. P • Avoidance of a total of two million tons of CO 2 emissions annually • Between 1990 and 2002 annual CO 2 emissions in Vienna were reduced by 3 % to approximately 6. 3 million tons • equivalent of 4 tons of CO 2 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

District Heating in Vienna Share 2005 Peak load heat plants 2, 5% CHP Industrial CHP Waste utilisation 66, 1% 7, 6% 23, 8%

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 Today Market 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 CO 2 Emissions Calculation from federal environmental agency Includes also CO 2 from waste incineration Value without waste ~ 95 kg/MWh used energy

Expected Results • Reduction of ~ 2, 7 million MWh fossil fuels Saves about € 53 millions energy import • 38% reduction of CO 2 emissions for domestic use 11% reduction of CO 2 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
