Solar energy institute ISET at the university of Kassel says 402 MW was commissioned in the first quarter of 2009, up from 325.4 MW in the same period a year earlier. The country's amended renewable energy law raised the long term power purchase rate by EUR0.01/kWh to EUR0.92 /kWh for onshore projects coming online this year. Some wind developers held off connecting capacity at the end of last year or delayed construction timetables to take advantage of the price hike (Windpower Monthly, February 2009). If the 94 MW commissioned in April is included, the 496 MW connected in the first four months of this year is almost identical to the 494.2 MW installed in the same period in 1998. Germany's total grid connected wind capacity was 24,055 MW at the end of April, says ISET.
