Repowering of 11 MW project from 1980s in Tehachapi
1 October 2003
Coram Energy LLC will add two 1.5 MW GE Wind Energy turbines at its 11 MW Coram Energy Project in Tehachapi, California. The units will replace the current German-built 40 kW Aeroman turbines from the 1980s. Their installation is the first step in a repowering project that next year will include two more GE turbines, says Coram president Brian O'Sullivan. The property along Cabin Ridge in Tehachapi is has an extraordinary wind resource, he says. He expects a gross capacity factor from the new turbines of about 46%. Coram has enough property to install about 50 MW, but Southern California Edison's transmission capacity out of Tehachapi is constrained and has been for a decade, says O'Sullivan. "Edison has been dancing around this issue for ten years," he says. "They didn't have the transmission when they signed contracts in 1996." He adds that the utility often must pay curtailment costs when generation exceeds transmission capacity. Construction will begin this month and is scheduled to be completed by the end of December.
