Texas came uncomfortably close to another round of rolling blackouts Tuesday night because grid operators misjudged the weather.
The Electric Reliability Council of Texas, which manages most of the state’s grid, had counted on a mild cold front sweeping the state, lowering demand for power. It didn’t happen. As a result, demand on the grid was about 3,000 megawatts higher than anticipated — or the equivalent of 600,000 homes.
The forecasting error, coming as 25% of power generation was off line for seasonal repairs, was another grim reminder of the vulnerability of Texas’s grid. Two months ago, a deep winter freeze knocked out almost half the state’s generating capacity, leaving millions of people in the dark for days. But Tuesday’s weather was hardly extreme, and the close call has raised questions about whether the grid operator, known as Ercot, can prevent a repeat of the February energy crisis.
“It’s a disgrace for a power grid in modern times to struggle to keep the lights on during a mild day,” said Daniel Cohan, an associate professor of environmental engineering at Rice University.
No doubt that comment is echoed by millions of Texans who wonder who’s in charge and why haven’t they been fired by now. No, not just the Electric Reliability Council. Throw in the State Legislature and the feeble hacks inhabiting the governor’s mansion and outbuildings.
Texas’ deep freeze didn’t just disrupt natural gas supplies throughout Lone Star country—its effects rippled across the country, extending as far north as Minnesota. There, gas utilities had to pay $800 million more than they anticipated during the event, and Minnesota regulators are furious. https://arstechnica.com/tech-policy/2021/04/houston-based-utility-wants-minnesotans-to-pay-for-texas-deep-freeze-problems/
“The ineptness and disregard for common-sense utility regulation in Texas makes my blood boil and keeps me up at night,” Katie Sieben, chairwoman of the Minnesota Public Utility Commission, told The Washington Post. “It is maddening and outrageous and completely inexcusable that Texas’s lack of sound utility regulation is having this impact on the rest of the country.” https://www.washingtonpost.com/business/2021/04/22/minnesota-texas-freeze-centerpoint-energy/
With its ill-equipped natural gas systems clocked by the cold, Texas’s exports across the Rio Grande froze up and 4.7 million customers in northern Mexico went without electricity — more than in Texas itself. The spot price of gas jumped 30-fold as far west as Southern California. And all the way up by the Canadian border, gas utilities in Minnesota that turned to the daily spot market to meet demand say they had to pay about $800 million more than planned over the course of just five days as the Texas freeze-up pinched off supplies.
