    Texas under power conservation alert amid freezing temperatures

    Texas under power conservation alert amid freezing temperatures

    HOUSTON — The Electric Reliability Council of Texas canceled a power emergency alert issued early Monday when freezing temperatures pushed demand, but encouraged continuing conservation as another cold night looms.

A second-level emergency alert occurs when power reserves fall below 1,750 megawatts. Under those conditions, ERCOT can bring online all available power plants and can start tapping neighboring power grids.

    To ease demand on the grid Monday, ERCOT asked big industrial and commercial operators to temporarily reduce their power use. The agency also brought on all additional generation resources, Woodfin said.

    Extreme temperatures

    The National Weather Service forecasts a high temperature of 40 degrees in Houston Monday. But temperatures are expected to drop to the mid-20s Monday night.

    A similar cold snap in February 2011 triggered the last round of rolling blackouts in Texas. Power distribution companies, such as Ce
