ENERGY POLICY IN THE FIELD OF ELECTRICITY, HEATING AND NATURAL GAS • Agreement of 20. March 1990 • Conversion of existing stations to combined heat and power supply; • Increased use of natural gas and other environmentally-friendly fuels • Electricity savings. • Biomass Agreement of 14. June 1993 • On the future development of biomass. Biomass was to be used in electricity supply from 2000. • The biomass agreement also covers expansion of the use of biomass in the heating supply sector. • It must be possible to use biomass resources in combined heat and power supply • in the natural gas areas • in the decentralised combined heat and power sector if there is a local desire to do so. • Reform Follow-up Agreement of 22. March 2000 • Implementation of the EU Gas Directive; • Future development in the heating supply sector; • The further organisation of the biomass agreement; • Balancing the costs for prioritised production between East and West Denmark; • Initiatives in the energy-savings field; • The green energy market; • In the heating supply field, the agreement means, among other things, that benchmarking and income limits for district heating producers, right of pre-emption in connection with change of ownership and adjustment of the obligation to connect may be introduced and that help is provided for bare field plants. • Agreement of 20. February 2002 • The Danish Electricity Supply Act was amended with regard to inclusion of payment for minimum capacity, handling of electricity overflow, takeover of non-performing windmills, electrical safety and emergency planning. • The framework conditions of decentralised combined heat and power plants were improved. • An opportunity was created for sea windmills to be installed at Samsø.
ENERGY POLICY IN THE FIELD OF ELECTRICITY, HEATING AND NATURAL GAS • Energy policy agreement, 21 February 2008 • The goal is that total gross energy consumption should fall by 2% in 2011 and 4% up until 2020 compared to 2006, corresponding to a drop from 863 PJ in 2006 to 846 PJ in 2011. • A very significant portion of further energy savings will be obtained by increasing energy companies' overall energy savings obligation from about 3 PJ/year today to 5.4 PJ/year from 2010. Preparation for the increased savings is being discussed with the companies.
Renewableenergy A steadily growing portion of energy consumption in the coming years should come from renewable energy sources. An increase to a 20% share of renewable energy has been agreed for 2011. The Danish EU goal for renewable energy will be binding on Danish energy policy until 2020.
WhyDISTRICT HEATING? • A cleaner environment • Reduced costs for the consumers and the society • A steady and secure supply
CHP Proportion of Electricity and District Heating Production
DANISHDISTRICT HEATING NUMBER OF CHP AND DH PLANTS IN DENMARKPublic-heat supply (cities): 16 centralized CHP 285 decentralized CHP 130 decentralized DH plantsPrivate heat supply (enterprises, institutions): 380 CHP 100 DH plantsIn all: 665 CHP 230 DH plants
DANISHDISTRICT HEATING • DISTRICT-HEATING SUPPLY: KEY FIGURES • If all of the DH pipes were laid end to end, they would stretch for 50,000 kilometers • In the last ten years, 400,000 new consumers were connected to the grid • 60 % of DH is delivered by the 55-60 largest DH plants (most are owned by local authorities) • In 2008, the following fuels were used to produce DH: • 46.2% renewable energy • nonrenewable waste 8.9 %, • biomass 35.4 % • other renewables 2.1 % • natural gas 27.8% • coal 22.0% • oil 3.8%.
