The Electric Reliability Council of Texas, which operates the grid, asked consumers to use less electricity wherever possible between 3 p.m. and 7 p.m. Thursday – a time of the day when demand typically peaks.
The request came in a scorching-hot week when energy use surged across the grid, breaking three consecutive July records. Meanwhile, a few power plants have unexpectedly shut down and forecasters were expecting less wind power Thursday afternoon, the council said.
“This is a precautionary measure to help ensure we can maintain overall reliability during this high-demand period,” Dan Woodfin, director of operations at the council, known as ERCOT, said in a statement. “Voluntary conservation, especially during the late afternoon and early evening hours, can help us ensure reliability throughout the ERCOT grid.”
