Coal plant retirements and high summer electricity demand lower Texas reserve margin">Coal plant retirements and high summer electricity demand lower Texas reserve margin
(Mon, 02 Jul 2018) The Electric Reliability Council of Texas (ERCOT), grid operator for most of the state of Texas, estimates a reserve margin of 11% for this summerâlower than previous years and ERCOTâs 13.75% reference reserve marginâindicating a smaller cushion of resources to meet summer peak demand and an increased risk of grid stress conditions. The lower anticipated reserve margin is mainly a result of three large coal plants retiring in early 2018 and forecasts of record-breaking summer electricity demand.
