REpower Systems AG has obtained an unlimited unit certificate from a certification authority in conformance with the system service ordinance (SDLWindV), which means that variants of REpower's MM series wind turbines are now fully certified. Requirements according to SDLWindV will be adhered to after June 30, 2011. After this date, wind turbines, as defined in the system service ordinance, must adhere to more stringent requirements regarding the behavior in the event of network outages. Â Â Â Â Â Â Â Â Â Â Â If the turbines cannot meet these requirements, the wind farms are no longer permitted to be connected to the network, according to the regulations of the Renewable Energy Sources Act.
With the aid of a unit certificate and an expert's opinion, wind farm operators can demonstrate that the requirements are adhered to at the network node point, according to REpower. The experts who are currently preparing system certificates for wind farms with MM turbines are supported by REpower to the best extent possible. The first system certificates are expected in the coming weeks.
Unit certificates for the new generators in the REpower 3.4M104 series should be available in the fourth quarter of this year. Due to the prototyping regulation, the wind turbines in this series can be connected to the grid through the end of January 2011 without requiring a unit certificate and an expert's opinion.
