ERCOT says it is prepared for a polar blast that is expected to bring sub-freezing temperatures to Texas this weekend.

Persistent triple-digit temperatures across much of Texas have forced ERCOT to issue yet another operating condition notice as it flirts with 80-GW demand.

Continued record electric demand, 13 GW of thermal outages and reduced renewable production forced ERCOT to again issue a conservation appeal.

ERCOT flirted with potential disaster July 11 after saying it was short on capacity, but system demand was reduced enough to keep the lights on.

The heat is back on in Texas after a brief respite, with ERCOT again setting records as peak demand reaches the extreme levels of ISO's predictions.

ERCOT has issued its third operating condition notice since April, warning of extreme, hot temperatures in several of its weather zones this weekend.

ERCOT's record peak of 74.8 GW could be broken this week as above-normal temperatures continue to bake Texas.

ERCOT has again issued an operating condition notice because of summer-like temperatures expected this weekend after a recent cold front.

ERCOT sailed through its second stress test of its winter readiness, easily meeting demand that came short of its peak during last February’s storm.

ERCOT is bracing for the second major cold front of the year, issuing an operating condition notice for Thursday and Friday ahead of “extreme cold weather.”
