04/12/2008Riga December 20085Risø DTU, Technical University of Denmark Renewable energy policy Long term goal The share of renewable energy must be increased to at least 30% of energy consumption by (EU goal 20% 2020). Policy Agreement 2008 The majority of the parties in the Parliament agree that renewable energy should cover 20% of Danish gross energy consumption in This corresponds to 22.4% renewable energy relative to final energy consumption.

04/12/2008Riga December 20086Risø DTU, Technical University of Denmark 2008 Energy policy: Better terms for wind turbines A renewable energy law to create greater transparency with respect to the legislative framework for the use of renewable energy. Better subsidy terms for new onshore wind turbines. Follow-up of re-powering regulations. Wind planning in the municipalities, including a green fund for restoring nature. 10 million DKK guaranteed financing to local wind project preliminary studies, etc. Possibility of economic compensation to neighbours for loss of property value due to new wind turbines. Possibility of local joint ownership. New offshore wind parks in 2012; tender for 2 times 200 MW late Action plan for developing offshore wind turbines. Survey of conditions for small wind turbines.

04/12/2008Riga December 20087Risø DTU, Technical University of Denmark Danish Subsidy terms for new wind turbines on land A replacement of the previous price premium of 0.10 DKK/kWh over the market price with a premium of 0.25 DKK/kWh for 22,000 peak load hours. A wind turbine at an average inland location typically takes about nine years to produce the equivalent of 22,000 peak load hours, whereas one at a good coastal location will take about seven years. A continued premium of DKK/kWh for compensation for balancing costs, etc. as at present. An additional DKK/kWh to cover wind turbine owners' contribution to a green fund. Scrapping regulations New turbines will receive the new price premium plus an extra supplement of 0.08 DKK/kWh for the first 12,000 peak load hours. The new extra premium replaces the current premium of 0.12 DKK/kWh which was adjusted to 0 DKK/kWh in pace with the market price increase from 0.26 to 0.38 DKK/kWh.

04/12/2008Riga December 20088Risø DTU, Technical University of Denmark Support scheme for offshore wind turbines Large scale project Tender – Cheapest, fastest and most beautiful Fixed price in full load hours = years of production Lowest bid for Horns Rev 2 = app. € cent 7 per kWh Lowest bid Rødsand II (after re-tendering) app. € cent 8 per kWh Other projects Premium financed as PSO added on top of market price
