Winter is almost here and many states have power grids unprepared for extreme weather, new report warns

Winter is coming and many states have power grids unprepared to handle the cold. Their possible failure leaves thousands of residents vulnerable to dangerous outages. "The nation's power grid faces a sharp risk of buckling in the event of major storms or prolonged cold snaps this coming winter, according to the regulator that monitors the electricity system," reports Evan Halper of The Washington Post

While the deadly 2021 grid failures in Texas may come to mind, swaths of the country face a similar threat. Halper writes: "A sweeping portion of the country that extends from Texas to the Canadian border is not adequately equipped for tough winter conditions, the North American Electric Reliability Corporation warned. . . . The report is a sobering assessment of a power grid that continues to fray and suffer from underinvestment, despite promises by politicians and regulators to shore it up following deadly blackouts in recent years."

Jim Matheson, CEO of the National Rural Electric Cooperative Association, which represents 900 local electricity providers, told the Post, "This forecast again shows that our nation faces looming grid reliability challenges while demand for electricity continues to soar. That's unacceptable and should be cause for concern for all Americans."

During stretches of sustained cold, natural gas generation is a weak link "as power plants and the infrastructure that delivers fuel to them are destabilized by the strain of extreme cold," Halper reports. 

While many states have been working to repair and prepare their systems, Texas has not been able to work fast enough. The reports showed "more power generation is at higher risk of energy shortages this winter than last because it is not bringing enough new power online to meet the state's surging demand, and its existing infrastructure has not been adequately weatherized," Halper adds. "New England meanwhile is struggling with its own natural gas infrastructure issues that create a threat in that region, the report found. And in a number of Mid-Atlantic and southeastern states, the demand for electricity at peak times has increased, while the amount of power available 'has changed little in these areas since Winter Storm Elliott caused energy emergencies across the area,' the report found."

As states move from traditional energy to renewables such as solar and wind, their impact also influences grid integrity. "Some, including Matheson's group, argued the report exposes the risks of tough new emissions rules proposed by the Environmental Protection Agency, which they say will further destabilize the system," Halper reports. "But others point to considerable research that finds the proposal does not threaten reliability and could ultimately strengthen the grid by more quickly bringing to market new technologies to store wind and solar power, which can be delivered to the grid when traditional power plants fail."
