Calpine's The Geysers Wins Ninth Consecutive Environmental Award from California Department of Conservation


MIDDLETOWN, Calif., Apr 16, 2010 (BUSINESS WIRE) --For the ninth year in a row, Calpine's geothermal operations at The Geysers is the winner of the California Department of Conservation (DOC) award for its ongoing commitment to safety and the environment and its excellence in lease maintenance.

"I'm proud to once again recognize Calpine for its efforts to enhance safety and practice environmental stewardship at The Geysers," California Department of Conservation Director Bridgett Luther said. "This is becoming something of a tradition: This is the ninth consecutive year that Calpine has received an outstanding field lease and facility maintenance award. The company's leadership and the facility's employees are to be congratulated for serving as a role model to industry."

Mike Rogers, Calpine's Senior Vice President, Geothermal Region, will accept the award on behalf of Calpine from Elena Miller, State Oil and Gas Supervisor California Department of Conservation.

"We are very pleased that for the ninth year in a row The Geysers has been recognized for exemplary performance in maintaining leases that are environmentally clean and safe," Rogers said. "We take seriously our responsibilities to put forth our best efforts to protect the environment and act as good neighbors in the community. This award is a testament to the team spirit and effort by our employees at The Geysers."

Calpine Corporation is the nation's largest renewable geothermal power producer. The company operates 15 geothermal power plants in The Geysers region of Northern California and is capable of generating up to 725 megawatts of green energy around the clock. Calpine uses a natural, clean energy source - heat from the earth's interior - to produce electricity. Because geothermal power plants do not burn fossil fuel, they have an inherent environmental advantage and are helping meet California's clean air goals. Calpine's operations at The Geysers accounts for about 20 percent of the green power (non-hydro) produced in California.

The Geysers provides substantial long-term support to local economies through wages, purchase of supplies and services, property taxes and royalties. The project also provides support to community improvement projects, supports local 911 services and encourages many volunteer efforts by its employees.

Recognizing the importance of The Geysers, Calpine is expanding and sustaining production from this renewable resource through wastewater recharge projects in which clean, reclaimed wastewater from local municipalities is recycled into the geothermal resource where it is converted into steam for electricity production. This provides an environmentally sound wastewater discharge solution for neighboring cities and increases the long-term productivity of The Geysers resource.

This year marks the 50th Anniversary of construction on the original power plant at The Geysers - the first commercial geothermal plant in the United States. Calpine is planning a series of events to celebrate this historic achievement.
