Pablo Vegas, the CEO of Texas grid operator ERCOT, said supply will be lowest compared to demand around 8 a.m. Thursday. However, about 10,000 megawatts of operating reserves will help keep the lights and heat on, even as demand spikes, according to the ERCOT grid and market conditions .

An arctic blast has enveloped Texas, plunging temperatures well below freezing in many regions of the state. Despite the extreme cold, the state’s electrical grid operator says it has met the higher demand for electricity.

Texas' main grid operator has projected that the state's growing demand for power could surpass its available energy supply beginning in summer 2026.

Power grid operator ERCOT’s worst-case projections show Texas coming up short in power supply as soon as 2027.

ERCOT expects the grid to operate normally, with no request for conservation. The weather watch will be in place for three days from Feb. 19-21.

The Electric Reliability Council of Texas said Monday that power grid conditions are expected to be normal during an upcoming period of bitterly cold weather coming to Dallas-Fort Worth and other parts of the state.

The Electric Reliability Council of Texas issued a weather watch Monday for a possible freeze later this week as Gov. Greg Abbott warned Texans to prepare for what could be the "coldest weather event of the year.
