"The Electric Reliability Council of Texas says a large number of power plants are offline, but it could not provide details as to what may be causing the “very concerning” number of outages. At the same time, the state is experiencing near-record demand for electricity in June."
"Texas’ main power grid struggled to keep up with the demand for electricity Monday, prompting the operator to ask Texans to conserve power until Friday.
The Electric Reliability Council of Texas said in a statement Monday that a significant number of unexpected power plant outages, combined with expected record use of electricity due to hot weather, has resulted in tight grid conditions. Approximately 12,000 megawatts of generation were offline Monday, or enough to power 2.4 million homes on a hot summer day.
ERCOT officials said the power plant outages were unexpected — and could not provide details as to what could be causing them."
