The Hermiston Power Project is a highly efficient gas-fired facility located in Hermiston, Oregon.  The plant utilizes two combustion turbines, each with its own heat recovery steam generator, that supplies steam to a single steam turbine generator. 

The Hermiston Power Project sells a portion of the power it produces into the Pacific Northwest and California power markets as part of Calpine’s Western region of power plants.  Calpine also leverages the plant’s quick-responding, natural-gas fired generation and its contracted transmission resources in the Northwest to help integrate wind energy into the region’s power grid.  Through agreements with the Constellation Energy Balancing Authority, Hermiston’s output is quickly increased or reduced to compensate for the variability of wind generation.

Fueled by natural gas and equipped with advanced emissions control technology, the Hermiston Power Project is one of the cleanest projects of its kind in the state.  In 2003, the Hermiston Chamber of Commerce nominated Calpine for the Governor’s Gold Award based on its community support activities.
