AUSTIN, Texas (AP) — The operators of the electric distribution grid that serves most of Texas foresees record-breaking electric power usage this summer while also facing tight operating reserves because of fewer generating units online.

The Electric Reliability Council of Texas on Thursday attributed the expected record peak usage this summer to the strong Texas economy. It blames the tight reserve generating capacity to the recent retirement of older generating units on the grid.

ERCOT President Bill Magness says it expects its wholesale market will provide strong financial incentives for generators to be available when demand increases. However, he said ERCOT also expects voluntary load productions and an increase in power sold in the market by industrial facilities that generate their own power.
