Uniform interface helps better manage farms with different turbines
The REguard Interface B IEC 61400-25 is available for any wind farm that uses REpower turbines. The system means the variety of interfaces that might be used in a wind farm can be replaced by a standardized, international version. Even wind farms with turbines from other manufacturers can be controlled with one interface. This considerably…

Repower has one GW installed in France
REpower Systems AG passed the 1GW milestone of wind energy systems installed in France. “One GW roughly corresponds to the output from one to two conventional electric power plants,” says Olivier Perot, Managing Director of Repower S.A.S. The manufacturer has installed about 500 turbines across the country since 2002. This corresponds to 20% of France’s…
Communities to own utililty-sized wind projects
Traditional wind plant developers often say their work benefits landowners by providing them with royalty or lease payments. While such an arrangement does provide some benefit to the community, the business model makes little provision for ownership or local participation. One community-based wind project in Minnesota works on another principle of making the landowners the…
