ERCOT said Tuesday that it confronts a historically low 8.1% planning reserve margin next summer in the face of continued high electricity demand from oil and gas producers in West Texas and the cancellation of several generation projects.

ERCOT set a pair of demand records, establishing new marks for wind power and November monthly demand as temperatures dipped in much of Texas.

ERCOT will have more breathing room as it prepares for record demand this summer after an additional 525MW of generation recently came online in Texas.

The ERCOT year-end Capacity, Demand and Reserves (CDR) report projects a 9.3% planning reserve margin for 2018.

ERCOT said it has sufficient capacity to meet demand for the next five years, including a forecast record peak this summer.

ERCOT’s electricity demand continues to grow more rapidly than expected, but the Texas ISO says it still has sufficient capacity to support reliability.

Texas regulators signed off on ERCOT’s plan to review its reliability standards and replace its loss-of-load expectation methodology for determining its reserve margin with one based on economics.
