SAN ANTONIO – Top officers of the Electric Reliability Council of Texas, the company that regulates the state’s electrical grid, mentioned Friday that no energy source was safe from the large winter storm this week.
The feedback got here as ERCOT moved out of emergency operations for the primary time since Sunday, bringing an finish to rotating energy outages that impacted tens of millions of individuals throughout the state.
ERCOT President & CEO Bill Magness took a way more personable stance throughout a morning media briefing, acknowledging that it was horrible to look at the fallout from widespread outages that passed off throughout under freezing temperatures.
“I really want to acknowledge the immense human suffering we saw throughout this event. When people lose power, there are heartbreaking consequences. The bottom line I guess, we had to watch that and fellow Texans had to experience it. When we had to make tough decisions, when the storm came in, ERCOT didn’t really have a choice,” mentioned Magness, referring to the transfer by operators early Monday morning to shed load from the state’s energy grid.
That alternative stored the state’s electrical grid from a potential catastrophic blackout, ERCOT officers beforehand mentioned.
A listening to earlier than the Texas Legislature, scheduled for Thursday, will start the possible months-long means of analyzing whether or not ERCOT was ready for the storm and took the right steps as soon as it arrived.

“So much enormously more demand than had been seen before, that certainly sets a new standard and I think we’ll go back and look at these estimation processes in general,” mentioned Magness, when requested about ERCOT winter evaluation stories from late final year.
Those stories said that officers believed that they had the producing capability to serve forecasted peak winter energy demand from December 2020 by means of February 2021 in Texas.
The lethal storm has reignited arguments in regards to the state’s energy plan, together with whether or not it over invested in renewable energy sources.
“We’ve spent over $7 billion building power lines going to wind and solar, which are undependable, and playing a roulette wheel I think, by allowing many of the backups of reliable energy to go dormant,” mentioned Commissioner Wayne Christian of the Texas Railroad Commission.
Reporting from the Texas Coalition for Affordable Power shows that the estimated cost for the wind energy transmission lines project was first slated to be under $5 billion, only to later have $2 billion added to the original estimates.
Dan Woodfin, ERCOT’s senior director of system operations, mentioned Friday that half of the put in capability of wind energy, the utmost capability an energy system can run at, was offline in the course of the storm.
Still, wind energy accounts for lower than 1 / 4 of the state’s electrical energy, a determine that’s decrease in winter months, ERCOT officers mentioned.
Christian, whose company oversees the state’s oil and gasoline business, described ERCOT as unprepared for the storm, claiming the company failed to take care of a backup provide of electrical technology.
Magness and Woodfin pushed again on that assertion Friday, claiming the structure of the energy market prevents them from having a backup provide.
“What we were seeing out on the systems as the storm came in was just about every generating unit that could, was running or attempting to run and that included backup generation from some industrial facilities that put that power that usually is used to run their systems on the grid,” mentioned Magness.
That provide, in line with ERCOT officers, would have been simply as weak to the weather.
“In this case, because we lost 40 percent of the generating capacity on the system, you would have had to have a back up of 40 percent of your expected peak demand,” mentioned Woodfin.
Christian mentioned Friday having the legislature assessment ERCOT and its operations was a mandatory first step.
