ERCOT Breaks Electricity Demand Record Again

Update: Adjusts 2/10/11 preliminary record of 57,282 MW to 57,265 MW, following final settlement.

Power Watch Cancelled

For the second time this month, the Electric Reliability Council of Texas, Inc. (ERCOT), the grid operator for most of the state, set a new record for winter peak demand with 57,265* megawatts (MW) today between 7 and 8 a.m. – nearly 1,000 MW higher than the previous record from Feb. 2, and 1,400 MW higher than the 2010 record.

"While it is always a good idea to conserve electricity when you can, we are cancelling the ‘Power Watch” at this time," said CEO Trip Doggett. "We appreciate the efforts of the consumers to reduce their electricity consumption during these recent critical days of severe weather."

The all-time peak demand for the ERCOT region is 65,776 MW, which occurred on Aug. 23, 2010.

In addition, the “transmission watch” for the Rio Grande Valley area has been cancelled.

* Note:  Following final settlement, the record was adjusted to 57,265 MW from the initial preliminary calculation of 57,282 MW.  The number is not final until completion of the market’s financial settlement process six months after the operating day.

The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to more than 26 million Texas customers -- representing about 90 percent of the state’s electric load. As the independent system operator for the region, ERCOT schedules power on an electric grid that connects more than 46,500 miles of transmission lines and 710+ generation units. It also performs financial settlement for the competitive wholesale bulk-power market and administers retail switching for nearly 8 million premises in competitive choice areas.

ERCOT is a membership-based 501(c)(4) nonprofit corporation, governed by a board of directors and subject to oversight by the Public Utility Commission of Texas and the Texas Legislature. Its members include consumers, cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities, transmission and distribution providers and municipally owned electric utilities.
