Turbine maker exploits a loophole

Google Translate

Although Denmark's new law for wind production incentives does not come into force until January, one company is already attempting to capitalise on a loophole. Danish Norwin, which has for many years run Dan-Service, a wind turbine servicing firm, has put a 599 kW machine on the market. According to the new law of the liberalised Danish electricity market, wind turbines larger than 600 kW receive a DKK 0.17/kWh production subsidy for their first 12,000 full load hours, while smaller machines are subsidised for the first 15,000 full load hours. The 3000 hour difference means extra income of DKK 300,000. The turbine has been type approved by the Risø National Laboratory. Risø's Jesper Skaarup says the declared capacity of a wind turbine is only a question of adjusting the blade pitch so that it won't produce 600 kW, even though the generator's maximum effect is in fact higher-in this case 610 kW. Any wind turbine can be adjusted in this way, Skaarup notes.
