Calpine Corp. has been working in cooperation with The Bay Area Air Quality Management District to respond to comments submitted by a number of environmental and local public interest groups, including the Sierra Club and EarthJustice, regarding the company’s proposed 600MW Russell City Energy Center to be built in Hayward, California, US. As a result, Calpine has agreed to changes in the project’s permit conditions, including reductions in a number of emission limits, which will make it one of the cleanest natural gas-fired power plants in the nation. Powered by cleaner burning natural gas, Russell City Energy Center will use advanced combined-cycle technology, which captures and uses the exhaust from gas turbines to generate additional energy in a steam turbine, resulting in an approximate 40% increase in fuel efficiency. The facility will use 100% reclaimed water from the City of Hayward’s Water Pollution Control Facility for cooling and will convert it into steam for electricity production. This environmentally responsible process conserves water and prevents four million gallons of wastewater per day from being discharged into San Francisco Bay. The Russell City Energy Center project is jointly owned by Calpine Corp., which holds a 65% stake and serves as managing partner, and an affiliate of GE Energy Financial Services, which holds a 35% non-managing member interest.
