The deep freeze trailing Winter Storm Fern has turned the United States power grid into a stress test in real time, and Energy Secretary Chris Wright is treating it as a national warning shot. As temperatures plunge and demand spikes, Wright has moved to unlock backup generation and coal capacity while bluntly cautioning that electricity use is racing ahead of what the system can reliably supply. His message is as political as it is technical, but the underlying concern is straightforward: in a storm like this, the margin for error on the grid is vanishingly thin.
At the center of the response is a flurry of emergency directives that pull in everything from data center generators to aging coal plants, framed by Wright as necessary to prevent deadly outages. The scramble is unfolding against a backdrop of longer term alarms from grid watchdogs about winter reliability and resource adequacy through 2035, and it is forcing a raw debate over how far the Trump administration should go in prioritizing reliability over pollution limits and clean energy development.
‘National energy emergency’ meets a fragile winter grid
Energy Secretary Chris Wright has been explicit that Winter Storm Fern is not just another cold snap but what he has called a “national energy emergency” for the power system. In a warning to energy reliability coordinators and balancing authorities, he stressed that surging demand in subfreezing conditions could collide with fuel constraints and mechanical failures, creating a cascading risk of blackouts that would hit homes, hospitals and critical infrastructure at once, according to Energy Secretary Chris. His department has framed the storm as a proving ground for whether the current mix of natural gas, coal, nuclear and renewables can withstand prolonged stress without resorting to rolling outages.
That concern is backed by the North American Electric Reliability Corporation, whose 2025 to 2026 Winter Reliability Assessment warns that large areas across the continental United States face elevated risks of shortfalls when demand peaks, a finding the Department of Energy has highlighted in its own planning for Fern through NERC Winter Reliability. The January 2026 snowstorm has already demonstrated how quickly those theoretical risks can become real, with heavy snow and ice damaging lines and substations and leaving utilities racing to restore power even as forecasters warn that outages could expand if the cold persists, according to Most power outages.
Unleashing backup generation, from data centers to coal plants
Wright’s most aggressive move has been to prepare what his department describes as a sweeping order to “unleash” backup generation, including diesel and gas units that normally sit idle behind the meter. In guidance to grid operators, he directed them to be ready to tap backup generators at industrial sites, large commercial buildings and facilities with battery storage when the storm hit, a directive detailed in Energy Secretary Chris. The Department of Energy followed that with formal Emergency Orders that authorize the deployment of backup generators across multiple regions, including actions taken subsequent to PJM’s application for relief, according to DOE Emergency Orders.
One of the most controversial steps has been a Department of Energy emergency order that allows data centers and other large electricity users to run their backup generators more freely, even when that means temporarily overriding air pollution limits. Reporting on the order notes that it explicitly prioritizes grid reliability over emissions rules, potentially exposing nearby communities to higher levels of pollutants during the emergency, as described in a Department of Energy. A related account notes that, as the eastern U.S. endures severe cold in Fern’s wake, the Trump administration is using the deep freeze to justify a broader push to relax pollution emissions limits during emergencies, according to eastern U.S..
Coal, natural gas and the Trump administration’s reliability pitch
Behind the emergency orders is a broader ideological argument from President Donald Trump and his energy chief that the United States has moved too fast to retire firm fossil fuel capacity. Wright has pointed to roughly 17 gigawatts of coal capacity that the administration has worked to keep online, arguing that those plants are now helping to stabilize the grid during Fern and reduce the need for utilities to ask customers to cut usage, according to Secretary of Energy,. In Texas, he has issued an order to grid operator ERCOT to leverage power from backup generators at data centers and other industrial sites when wind and solar are not generating enough electricity, a directive described in coverage of Wright also issued.
The administration has paired that message with a sharp critique of what it calls “energy subtraction” policies. In a statement previewing the backup generation order, the Department of Energy said The Trump administration “will not stand by and allow the previous administration’s reckless energy subtraction policies and bureaucratic red tape to put Americans at risk of blackouts during extreme weather conditions,” language that appears in the department’s own description of the plan in The Trump administration. At the same time, a separate regulator-focused analysis notes that the administration has sought to limit the construction of clean energy projects such as wind and solar while removing regulations on fossil fuel plants, arguing that gas and coal provide more dependable electricity than solar and batteries, according to administration has sought.
Watchdogs warn demand is outpacing supply
Even as Wright leans on emergency tools, grid watchdogs are warning that the underlying math on supply and demand is moving in the wrong direction. NERC has cautioned that electricity demand and prices are quickly becoming a political flash point as new loads such as data centers and electrified heating expand faster than firm capacity additions, a trend highlighted in a report that notes NERC’s concerns about the next five years and is summarized in NERC’s report. A separate long term reliability assessment finds “worsening” resource adequacy through 2035, with the lowest reserve margins in regions that are retiring conventional plants fastest, according to NERC Warns of.
Those structural warnings are colliding with the immediate reality of Fern. One analysis notes that the United States is facing growing risks of winter power outages because of rising demand, a changing fuel mix and exposure to high winds and prolonged freezes, according to US faces growing. Another account of the January 2026 snowstorm argues that winter storms are straining the U.S. electric grid in ways that expose vulnerabilities for utilities and large electricity users, a point underscored in an assessment that says the event demonstrates how extreme weather can stress both supply and transmission, as described in January 2026 snowstorm.
Natural gas bottlenecks and regional stress tests
While Wright has focused on generation capacity, Fern is also exposing how dependent the grid has become on natural gas delivery. Analysts note that at the center of the current strain is the nation’s heavy reliance on gas pipelines and production, with one expert, Didi Caldwell, founder and CEO of a consulting firm, warning that the system is vulnerable when both power plants and heating demand draw on the same constrained fuel, according to At the center. The storm has reached deep into the South and knocked out about 12 percent of the country’s natural gas production, limiting supplies to power plants just as they are needed most, a figure cited in an analysis of how the deep freeze is putting the grid for 67 million people at risk, according to Reaching deep into.
