"HOUSTON — Texas’ power grid manager on Thursday again asked residents to cut their electricity use as the state endures another stretch of sizzling summer heat. The request carried fresh urgency, coming the day after the system was pushed to the brink of outages for the first time since a deadly winter blackout in 2021.
The request by the Electric Reliability Council of Texas, which serves most of the state’s 30 million residents, came a day after low energy reserves prompted the grid operator to issue a level 2 energy emergency alert. Operating reserves fell as demand surged amid the heat, and power from wind and solar energy sources proved insufficient, according to ERCOT.
It was the first time the council entered emergency operations since a deadly 2021 ice storm knocked out power to millions of customers for days and resulted in hundreds of deaths."
