PowerEmissions Controls, Changing Usage Widen Heat Rate Chasm Between Coal and Gas Power Plants
Between 2006 and 2015, annual average heat rates from the nation’s natural gas–fired power plants plunged 7%, while only decreasing 1% for coal plants, the Energy Information Administration (EIA) revealed on August 21. Heat rates, which are measured in British thermal units per kilowatt-hour (Btu/kWh), refers to energy conversion efficiency, calculated based on the amount […]
