Following a continued downturn in operating results, Renewable Energy Corporation (REC) will close its 650MW multicrystalline wafer plant at Herøya, Norway by the second quarter of 2012. The closure of the Herøya plant, in the south of the country, will signal the end of all REC’s wafer operations in Norway after the closure of the Glomfjord monocrystalline plant on March 20, 2012.
