Mint Farm Generating Station facts
The Mint Farm facility came online in January 2008, and was acquired by PSE in December 2008. The plant employs modern, “combustion-turbine, combined-cycle” technology that allows it to generate electricity using both a natural gas cycle and, from the exhaust heat of its power-generating turbine, a steam cycle. The two-stage process boosts operating efficiency, lowers fuel costs, and cuts air emissions.
Combined-cycle plants like Mint Farm operate much more efficiently than simple-cycle gas-fired plants. The latter typically run only to help meet daily or seasonal peaks in customers’ power usage, while combined-cycle plants often operate to help meet utility customers’ base power requirements. They also complement hydro- and wind-powered generation because gas-fired plants can operate on a firm schedule while power generation from hydro and wind-generating facilities is dependent upon the seasons.
- The Mint Farm Generating Station is the newest of the eight natural gas-fired power-producing plants we own and operate in Washington.
- The station can produce 310 megawatts of electricity when running at maximum capacity — enough power to meet the annual needs of 220,000 households.
- The plant uses a combined-cycle combustion turbine technology, a two-stage process that boosts operating efficiency, lowers fuel costs and reduces air emissions.
- The facility provides 21 full-time jobs.
