WASHINGTON—EPA presented Energy Star Combined Heat and Power (CHP) awards to four organizations for using highly efficient systems to save energy, lower greenhouse gas emissions and reduce air pollution. CHP (cogeneration) is up to 60 percent more efficient than producing heat and power separately.

CHP is the simultaneous production of electricity and heat from a single fuel source, such as natural gas, biomass, biogas, coal, waste heat or oil. CHP is not a single technology, but an integrated energy system that can be modified depending upon the needs of the energy user.

This year’s winners are:

  • Calpine Corporation’s Carville Energy Center (CEC) (St. Gabriel, La.).
  • The Commonwealth of Massachusetts Department of Corrections Bridgewater Correctional Complex (Bridgewater, Mass.)
  • Equity Office Properties (New York City, N.Y.)
  • Patterson Farms (Auburn, N.Y.)

Conventional fossil-fueled power plants produce power with a typical efficiency of about 30 percent. The projects being recognized by EPA today are reaching operating efficiencies of at least 50 percent

Since 1999, EPA has given the ENERGY STAR CHP Award to recognize organizations and institutions that install exceptionally efficient CHP systems. In 2001, EPA formed a CHP Partnership working with organizations to reduce the environmental impact of power generation. In addition, the partnership supports the development of new projects that have significant energy, environmental, and economic benefits.
