Future Ancillary Services in ERCOT

Posted: September 27, 2013 - 12:20 / ERCOT / White Papers

Over the years, ERCOT has been successful in complying with the National Electric Reliability Corporation (NERC) standards with the Ancillary Services (AS) that it has procured and deployed. For example, ERCOT’s average monthly Control Performance Standard (NERC CPS1) scores have consistently been around 165% over the last year, which is a clear indication that ERCOT is performing extremely well in controlling frequency. Other performance measures also reflect that the ERCOT AS construct currently in place has served ERCOT well from a reliability and secure operations perspective.
