DALLAS (AP) - The operator of the electric grid that lights most of Texas has discontinued a prior alert asking customers to use less electricity.
The Electric Reliability Council of Texas had issued the alert because of the extreme cold. ERCOT had also warned of an increased risk of rotating blackouts in the Rio Grande Valley of South Texas amid high demand for power.
But ERCOT on Friday cancelled the alert and said the valley was no longer under threat of blackouts.
Meanwhile, some Central Texas schools, including the Austin school district, canceled classes Friday due to weather and road conditions. The University of Texas at Austin and Texas State University in San Marcos delayed opening until noon.
Oncor reported nearly 1,000 customers without power in North Texas, but that number dwindled substantially through Friday.
