Regulators warned Thursday that the grid from Texas to the Midwest is at risk of shutting down in the event of a long-term deep freeze this winter.
NERC’s outlook suggests that 40% of residents froze during the cold weather last winter and are not ready to repeat their stay in the dark.
John Moura, director of reliability assessment and performance analysis at NERC, said in a media briefing Thursday that a widespread outage in Texas remains a “valid” concern.
“The industry has done everything it can, but there is still work to be done to make sure it is resilient to these weather patterns. It will take more than a year to build it. “He said.
The February power outage in Texas killed more than 200 people and caused $ 20 billion in damage. Fossil fuel proponents pointed out the increasing use of intermittent wind power, which produces 23% of Texas electricity. Others said the natural gas machine froze under extreme conditions.
According to another report, the plunge in natural gas production was one of the main causes of gas plant shutdowns in Texas. report NERC has been released.
Texas Monthly paper “A backward regimen used by state energy authorities to predict weather — a methodology that minimizes the impact of intensifying factors such as climate change. Scientists say winter storms could be more cruel. I’m saying. “
NERC also said that extreme weather events caused by climate change can test power grids like never before, running out of historically sufficient supplies and testing again. In fact, Thursday’s report was the first to look at the resilience of the grid to extreme weather events. Historically, NERC has measured reliability primarily based on available capacity, including reserves.
Supply issues are now another factor, according to Thursday’s NERC report. The southwestern United States, including New England and California, is particularly vulnerable to natural gas.
Insufficient. He also told NERC that some generators are not expecting additional coal supplies for the rest of the year due to railroad constraints.
Fitch Ratings analysts said at a meeting earlier this month that the US power grid has become less elastic and reliable, and extreme weather has made more Americans unavailable in the last few years. rice field.
In a presentation at the Edison Electric Institute’s Treasury Conference, analysts said the weather accounted for 25% of the utility company’s credit downgrades between 2017 and 2021.
Extreme heat could also test the US power grid.Nature maintenance warnings were issued as citizens in Texas in the summer Supported by Tess in warm weatherThat power system t.
“Climate change is expected to continue to challenge electricity reliability,” Fitch analyst Barbara Chapman said at the event, according to Bloomberg News.
Due to climate change and the resulting extreme weather events More elastic national power grid, Smarter and more responsive to both supply and demand.
