The Electric Reliability Council of Texas (ERCOT) indicated in a press release on Monday that the council instituted rotating outages before 2 a.m.
“Every grid operator and every electric company is fighting to restore power right now,” said Bill Magness, president and CEO of ERCOT.
In a conference call, Dan Woodfin, ERCOT’s senior director of system operations, explained the council’s decision to implement the controlled outages, citing a “peak demand” for electricity on Sunday night that caused generating units to “begin tripping offline” after 11 p.m.
“We implemented these controlled outages that are currently in progress,” Woodfin said.
“The way this works is we determine how much reduction in demand is needed to maintain that supply-demand balance and we tell the transmission owners around the state how much reduction we need and they determine where and how to implement those reductions on their system.”
Woodfin indicated these controlled outage events could last throughout Monday, noting ERCOT is “working tirelessly” to get power back on.
Electricity providers are not necessarily able to rotate outages due to the “severity” of the demand brought about by the unusual winter storm, according to Woodfin’s statement. He indicated that the demand is “more megawatts and longer” than ERCOT has ever had to fulfill in the past.

“This event happened quickly and the amount of load we needed to remove from the grid was significant and in was in a matter of short time. We maxed out on available circuits on what we have to not interrupt critical load,” said the company.
CenterPoint Energy, the primary natural gas provider for households in the Houston area, has an online outage tracker, but their system crashed due to a surge in demand.

CPS Energy, the municipal electricity company in San Antonio, has an outage map here.
Similar to many other utility companies in the state right now, CPS Energy said, “Due to the unprecedented severity of the weather across the state and the condition of the grid, some rotating outages may last longer than 15 minutes and will likely continue throughout the day.”
