TCEQ issues permit for 470-megawatt 'peaker' plant
The Texas Commission on Environmental Quality issued an air permit to Guadalupe Power Partners for a 470-megawatt, gas-fired power plant intended for peaking use. The plant, near San Antonio, is a simple-cycle design -- natural gas-fueled turbines that can quickly reach capacity. The new units will be built at an existing Guadalupe site that already has a 1,070-megawatt combined-cycle power plant that opened in 2001. Combined-cycle plants are more efficient, pairing a gas-fired turbine generator with a steam generator that uses the exhaust heat from the turbine unit, but take longer to meet capacity. Guadalupe Power must also get a greenhouse gas emissions permit from the U.S. Environmental Protection Agency. Reuters has a complete report here.
