(Bloomberg) -- Texas is forecast to use an unprecedented amount of electricity for this time of year as frigid temperatures descend on the second-largest US state on Friday.

The winter record of 69.8 gigawatts is expected to fall with demand projected to reach at least 70.9 gigawatts early Friday, according to the Electric Reliability Council of Texas, which oversees the grid. A gigawatt is enough to power about 200,000 Texas homes.

The price of power to be delivered Friday evening surged above $500 per megawatt-hour in some areas, up more than five fold from Thursday.

Texas officials have been assuring residents the power grid is up to the challenge and there’s no danger of a repeat of the February 2021 catastrophe that killed more than 200 people. This week’s storm is forecast to be shorter and less extreme.

More than 53,000 customers didn’t have power in the state at nightfall Thursday, according to PowerOutage.us.

Ercot and state regulators have worked to winterize equipment and take other steps to protect the grid during extreme weather, but critics have warned those reforms won’t be enough.
