ERCOT and PUC officials say grid is prepared for incoming cold; cite added capacity and winterization
Summary
ERCOT CEO Pablo Vegas and Public Utilities Commission Chair Thomas Gleeson told reporters the grid has added supply and been winterized since 2021, citing more than 13,500 megawatts added since last March, 300-plus inspections, and firm fuel supplies intended to maintain reliability during the cold event.
Officials from the Electric Reliability Council of Texas (ERCOT) and the Public Utility Commission of Texas told reporters the state's electric grid is in a planning and preparation posture and that they expect adequate supply to meet demand during the approaching cold weather.
Pablo Vegas, CEO of ERCOT, said the operator is coordinating daily with generators and transmission providers and has conducted more than 300 inspections of supply resources and transmission facilities this winter. "We expect to have adequate supply to meet demand during this cold weather event," he said. Vegas noted that the grid has added more than 13,500 megawatts of new supply since last March and pointed to a mix of solar and battery resources, plus thermal generation, as contributors to reliability.
In the briefing, ERCOT described reliability tools including firm fuel supply commitments that represent more than 4,000 megawatts of generators with backup fuel on site, and said battery storage helps bridge morning ramps when the sun is not available.
Thomas Gleeson, chair of the Public Utility Commission of Texas, said PUC staff have been in constant communication with generators and transmission/distribution utilities and reported that generators have confirmed adequate fuel and utilities have been working to mitigate risks, including vegetation management along thousands of miles of lines.
During a question-and-answer exchange, a reporter asked for a household equivalency for the new generation. ERCOT responded that one megawatt can power about 250 homes in Texas and that 13,500 megawatts multiplied by that figure translates to "several million homes" of incremental capacity.
PUC officials directed residents experiencing outages to consult the PUC website for restoration information from local utilities. Officials said they do not anticipate statewide reliability issues but stressed the operational challenge of managing diverse conditions across Texas on a single day.
The officials' assurances follow public concern rooted in Winter Storm Uri in 2021; ERCOT and PUC officials said changes since then (including inspections, winterization and added supply) make the grid more resilient for this event.
