GENERAL INFORMATION ON DENMARK
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.

Renewable energy 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.

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%.

Priority 1 is the maximum reference price is above 300 DKK / MWh, priority 2 is between 200 to 300 DKK / MWh, while the priority 3 is below 200 DKK / MWh. If all of the estimated natural gas fields will be converted to district

Geothermal Energy
What is viewing?• Geothermal heat, why?
Viborg Geothermal Project was started by Viborg District in order– to increase supply and– generate a CO2 mitigation in the future distribution
of heat.
The geothermal potential Kvols expected to lie in the range 16-32 MW thermal exclusive heat pumps.
Similarly, oil exploration well in Kvols is a similar drilling by Klejtrup (Hobro 1), giving a additional opportunities for geothermal heat.
