Natural Gas-Fired Plants

Explained simply, gas-fired plants are based on aircraft jet engine technology. Like coal-fired plants, the natural gas fuel is burned. But instead of steam, the hot compressed exhaust gases expand through a turbine to generate electricity.

Natural Gas-Fired Plants

Bennett Mountain Power Plant

The 164-megawatt Bennett Mountain Power Plant located in Mountain Home, about five miles east of the Evander Andrews Complex, is a simple cycle combustion turbine power plant. Construction was completed in 2005 and the plant produced its first electricity for the grid in late February 2005.

Both the Danskin and Bennett Mountain plants are "peaking" generating resources, for use primarily in meeting short-duration demands for electricity during hot summer afternoons when air conditioning and irrigation loads reach their highest point.

Danskin Power Plant

Housed with the Evander Andrews Complex, the 261-megawatt Danskin Power Plant consists of three natural gas-fired simple cycle combustion turbines–one, 171-MW unit and two 45 MW units.

On an airplane, a combustion turbine is used to create thrust to push the plane through the sky. In a power plant application, that thrust turns an electrical generator to produce electricity.

This plant was constructed to help Idaho Power have adequate generating resources to meet present and future energy needs.

Langley Gulch Power Plant

To fulfill Idaho Power’s commitment to meet growing electricity demands, the company added a new generation resource in July 2012. The Langley Gulch Power Plant is a clean, quiet, highly-efficient, combined-cycle combustion turbine (CCCT). It uses two turbines to generate electricity—one with natural gas, the other steam. The exhaust heat from the combustion of natural gas is used to make steam, which drives the steam turbine. The plant's generating capacity ranges from 300 megawatts in the summer and 330 megawatts in winter.

In addition to providing electricity for Idaho Power’s customers, Langley Gulch helps integrate intermittent and alternative resources such as wind and solar from area projects in our system. The plant is located on 137 acres in rural Payette County.
