So far, plans had called for a 10 percent reduction of feed-in tariffs incentives utilities are obliged to pay for power generated from renewable sources in early 2010 and another 10 percent a year later. BSW is now proposing to add a cut in mid-2010.
"Some 10 percent on January 1, five percent at mid-year and then another 10 percent at the move into 2011," Asbeck said, according to an excerpt of an interview to be published in weekly Focus-Money magazine.
Utilities are obliged to pay 43 cents per kilowatt hour of electricity produced for 20 years for systems installed in 2009. Companies including Solarworld have called for a faster reduction of subsidies in exchange for international environmental and quality standards in regulation.
According to Handelsblatt newspaper, the BSW association is set to make its proposal to policymakers at a January 13 meeting.
Germany is a world leader in green energy with a 15 percent share of all electricity produced and wants to double that to 30 percent by 2020.
