The electric grid operator for most of Texas expects to have sufficient resources in place to meet what it expects to be record power demand this summer.

The Electric Reliability Council of Texas (ERCOT) said summer loads would likely reach 77,317 MW, which would be a new system-wide peak demand record for the region. The summer projection, part of the Seasonal Assessment of Resource Adequacy (SARA) issued this week, accounts for load reductions based on an incremental rooftop solar capacity forecast.

ERCOT, which serves about 90% of the state, said there would be 91,392 MW of resource capacity available during summer peak demand hours. This includes 473 MW of planned natural gas-fired, utility-scale solar and wind capacity. Additionally, the grid operator expects to have 2,035...
