The California Energy Commission's Public Interest Energy Research (PIER) program has awarded three companies grants totalling $5 million for investigations into new low-speed wind turbine technologies and management of a variable energy resource. The grants are being matched with over $7 million from the companies -- Clipper Windpower, General Electric and Wind Tower Composites (WTC). Clipper will look at technologies designed to work efficiently at low wind speeds and at variable output management, while GE's grant is for an advanced rotor 1.5 XLE wind turbine demonstration with variable output management through forecasting and collaborative generation. The WTC grant is to test composite towers for low to moderate wind speeds. The awards are a result of a solicitation in July 2004.
