Calpine Buys Geothermal Assets in Northern California
LCG, Oct. 31, 2001--Calpine Corp. yesterday announced it had acquired two subsidiaries of Mid-American Energy Holding Co. and in the process got the companies' geothermal resource assets, contracts, leases and development opportunities associated with the Glass Mountain Known Geothermal Resource Area in Siskiyou County, Calif., near the Oregon border.Financial details of the deal were not disclosed.Before the acquisition of California Energy General Corp. and CE Newberry Inc., Calpine owned about 40 percent of the leases in the 66-square-mile area, and says that the two acquisitions give it "essentially all" of the development rights within the Glass Mountain area.Calpine said the purchases are directly related to its plans to develop the 49.5 megawatt Fourmile Hill Geothermal Project located in the Glass Mountain area. Power from the project, which is in advanced development and is projected to be online by late 2004, is committed to Bonneville Power Administration under a 20-year contract.Fourmile Hill has also qualified for a California Energy Commission renewable energy production incentive which is valid for the first five years of the facility's operation and is valued at up to $21 million, Calpine said."We are pleased with the initial resource data and are confident about the potential of the Glass Mountain (area) as a new green power resource," said John Miller, Calpine vice president of program development. "This transaction strengthens our commitment to renewable energy and reflects Calpine's strategy to manage the entire geothermal resource. In doing so, we will be better positioned to optimize power production and effectively coordinate the power production with other important uses of the area."Calpine has been involved in geothermal power production since 1985 and, through its operations at The Geysers north of San Francisco, generates about 850 megawatts, making the company the largest producer of electricity from renewable geothermal resources in the world.
