But the mix of power generators, how they are installed and maintained and interconnected, how many power generators there are, what sort of backup plans or emergency plans are developed, are the responsibility of Texas alone. They are not regulated by the Federal Energy Regulatory Commission.
Texas power generators have to abide by EPA imposed limits for emissions of nitrogen oxide, carbon monoxide, sulfur dioxide, mercury along with release of wastewater. Those limits prevent them from generating the maximum amount of power that is possible.
SUMMARY
The ERCOT region is expected to have sufficient installed generating capacity to serve peak
demands in the upcoming spring season, March – May 2022, under normal system conditions
and most of the reserve capacity risk scenarios examined. The spring capacity planning
reserve margin is forecasted at 52.5%, which is intended to cover resource outages, lowerthan-expected renewable output, and higher-than-expected customer demand.
Based on expected spring peak weather conditions, the peak demand for Spring 2022 is
forecasted to be 64,729 MW.
A total of 94,394 MW of resource capacity is expected to be available for the spring season.
Since the start of winter 2021-22, 31 units have been approved for synchronization to the
ERCOT Grid. These units are comprised of wind, solar, and energy storage projects1 that total
1,027 MW based on the expected capacity contribution for wind and solar at the time of peak
demand, and spring-rated capacity for thermal resources. An additional 367 MW of planned
resource capacity constituting gas-fired and wind units are expected to be available to meet
the spring peak demand.
