Winter Storm Fern strained the largest electricity grid in the United States in late January 2026, prompting federal authorities to issue emergency orders aimed at keeping the lights on. The grid stress, fuel constraints, and wholesale price spikes during the storm are expected to put upward pressure on electricity bills for households across the Mid-Atlantic in coming billing cycles. What the storm exposed, however, goes deeper than a single weather event: it revealed structural weaknesses in how the region generates, prices, and delivers power during extreme cold.
Federal Emergency Orders and 20,000 MW of Lost Generation
PJM Interconnection, the grid operator serving 65 million people across 13 states and the District of Columbia, filed an urgent request for federal emergency authority as Winter Storm Fern bore down on the region. The grid operator warned of extreme demand projections and issued a series of alerts, recalls, and advisories signaling that normal operations could not hold. Generation outages were trending toward 20,000 MW at the time of filing, a loss of capacity that PJM warned could increase the risk of service interruptions if conditions deteriorated further.
The U.S. Department of Energy responded by finding a statutory emergency and issuing Order No. 202-26-02 under Section 202(c) of the Federal Power Act. That order allowed certain generation units to operate beyond specified emissions and effluent limits under emergency authority so that additional megawatts could be supplied to the grid. The constraints PJM faced were not limited to weather alone. Fuel shortages compounded the problem, leaving some plants unable to run at full output even as demand climbed toward record territory. A separate emergency application from PJM laid out the reliability risk in detail, describing conditions that required extraordinary generation dispatch to prevent widespread service interruptions and warning that the system’s normal reserve margins had effectively evaporated.
Data Centers Called Into Service as Grid Stress Deepened
The initial emergency order was not enough. As conditions worsened, DOE issued a second distinct authorization, Order No. 202-26-06, which directed backup generation at data centers and other large electricity consumers to fire up as a last resort before and during the most severe stage of grid emergency, known as EEA3. That step is rarely taken and signals that the grid operator had exhausted nearly every other tool available to balance supply and demand, including voluntary conservation appeals, emergency imports from neighboring regions, and the dispatch of high-cost peaking plants.
Activating private backup generators at data centers carries its own complications. These diesel and natural gas units are typically permitted only for limited emergency use, and running them at scale raises questions about air quality, fuel logistics, and the long-term reliability expectations placed on commercial facilities that were never designed to serve as grid resources. The fact that PJM needed to tap this reserve capacity illustrates how thin the margin had become. Demand on the grid was forecast close to winter records, though temperatures in some parts of PJM territory ultimately came in less severe than initially projected, which allowed the operator to ratchet down peak forecasts somewhat. Still, spot electricity prices topped $3,000 per MWh in parts of the grid during the worst hours, costs that can flow through to consumer bills as utilities reconcile storm-period purchases, depending on how suppliers and regulators treat those charges.
Natural Gas Prices Hit Three-Year Highs, Driving Wholesale Power Costs
The bill increases hitting Mid-Atlantic households are not simply a function of higher electricity demand. They reflect a fuel-market chain reaction. Natural gas, which fuels a large share of PJM’s generation fleet, soared to a three-year high as the winter storm disrupted production and spiked heating demand simultaneously. When gas becomes expensive or physically scarce, wholesale electricity prices surge because generators pass fuel costs directly into their market bids. Regional spot prices for both gas and power climbed sharply, and those spikes ripple outward over weeks and months as utilities true up their actual procurement costs against the rates customers pay under default service or competitive contracts.
This dynamic is well understood but poorly defended against. The Mid-Atlantic grid remains heavily dependent on just-in-time natural gas delivery, and pipeline capacity into the region has not kept pace with the shift from coal to gas-fired generation over the past decade. During extreme cold, residential heating competes directly with power plants for the same limited gas supply, creating a bidding war that inflates costs for everyone. The result is that a few days of brutal weather can produce bill increases that persist for months, disproportionately burdening households with limited ability to absorb sudden cost swings and amplifying existing energy affordability concerns in low-income communities.
Maryland’s Price Collar and the Political Response
Even before Winter Storm Fern, electricity costs in the PJM region had become a political flashpoint. Maryland Governor Wes Moore’s office announced what it described as a significant policy win: an extension of a price collar on PJM’s capacity market through 2030, which the governor’s team said would save state residents billions on electricity bills. The price collar caps how high capacity auction prices can climb, limiting the amount that generators can charge for committing to be available during peak demand periods and, in theory, shielding ratepayers from the most extreme market outcomes.
That claim deserves scrutiny. A price collar does reduce the ceiling on capacity costs, which is one component of a customer’s bill, but it does not directly address the fuel-price volatility that drove the most dramatic wholesale power spikes during Winter Storm Fern. Nor does it resolve structural issues such as aging transmission infrastructure, the concentration of generation in gas-fired plants, or the operational risks highlighted when PJM had to rely on backup generators at data centers. Maryland’s broader policy framework, including statewide energy and climate priorities and legally required accessibility and transparency standards reflected in the state’s accessibility guidance, suggests that officials are trying to balance affordability, reliability, and environmental goals. The storm’s aftermath will test whether tools like the capacity price collar are sufficient, or whether deeper reforms to planning, fuel security, and demand-side management will be needed to prevent the next cold snap from producing another round of emergency orders and sticker shock on household power bills.
