Gas reliability remains central to grid resilience, report says

Post-Uri reforms showed progress, not closure

A new report prepared by Energy Ventures Analysis for the Natural Gas Council argues that reforms made after Winter Storm Uri in 2021 helped the U.S. energy system perform better during Winter Storm Fern in January 2026. But the same report also warns that the hardest test may still lie ahead.

According to the supplied Utility Dive source text, the study found that gas industry changes put in place after Uri helped insulate the electric grid from outages during Fern, even as prolonged cold pushed consumption near record levels across the Central and Eastern United States. The report credits winterization investments, more flexible liquefied natural gas operations and heavy use of storage with helping preserve reliability during the event.

In practical terms, that is evidence that the gas and power system learned something from Uri, the 2021 storm that exposed dangerous interdependencies across Texas and the broader energy sector. But the report stops well short of declaring the problem solved.

What held up during Winter Storm Fern

The most concrete finding in the source text is the role played by storage. During peak periods, storage supplied roughly 30% of total U.S. gas demand, helping the system absorb extreme cold-driven stress.

The report also highlights winterization upgrades and operational flexibility in LNG systems. Those changes appear to have reduced the likelihood that cold weather would simultaneously choke fuel supply and cripple generation, the kind of compounding failure that made Uri so destructive.

That matters because natural gas remains the largest single source of electricity generation in the United States, accounting for more than 40% according to the source text. If gas falters during a weather emergency, the electric system is exposed quickly.

Fern therefore served as an important real-world check on whether post-2021 reforms had improved resilience. The conclusion from the report is that they did, at least under the conditions encountered this January.

Why the warning remains serious

The report's central caution is straightforward: Fern was not Uri. The authors say “the full stress test of post-Uri improvements has not yet occurred under Uri-level temperature conditions.” That caveat is the most important sentence in the entire assessment.

In other words, the system may be stronger, but it has not yet been tested against the same degree of extreme cold that exposed its vulnerabilities in 2021. A better performance during a major winter event is encouraging. It is not proof that the interdependent gas-electric system can withstand the worst case.

That distinction matters for planners, regulators and utilities now entering another season of weather risk. It suggests the correct policy response is not complacency, but continued hardening and coordination before a more severe event forces the issue again.

What the report recommends next

The study calls for stronger coordination between gas and electric sectors. Specifically, the source text says the authors recommend firmer fuel assurance for generators, protections for critical gas infrastructure during grid emergencies, and continued investment in pipeline and storage capacity.

Each of those proposals addresses a different weak point in the chain. Fuel assurance aims to reduce the chance that power plants lose access to gas when demand spikes. Emergency protections for critical gas infrastructure recognize that the fuel system itself may need priority treatment during electric disruptions. Continued infrastructure investment is aimed at preventing bottlenecks before they become crisis points.

These are not abstract planning ideas. They reflect the reality that the gas and electric sectors are deeply interdependent, yet often governed, scheduled and protected through different operational logics.

A broader reliability debate is taking shape

The report lands as utilities and regulators confront several overlapping pressures. The source text points to rapid load growth from electrification, data centers and industrial demand, all arriving as weather-related stress becomes a more persistent feature of grid planning.

That combination changes the reliability discussion. Extreme weather is not a rare outlier; demand growth is not a distant projection; and fuel supply issues cannot be treated as separate from electric system performance.

Utility Dive also cites an outside comment from Pawan Vaswani of Publicis Sapient, who said operators need a better understanding of where bottlenecks can emerge across interconnected energy systems during extreme conditions. That observation fits the broader message of the report: vulnerabilities often do not appear clearly in normal operations, but become visible under stress.

The central challenge, then, is no longer just building enough generation. It is managing the dependencies between gas production, storage, pipelines, power plants and grid operations under increasingly volatile conditions.

What this means for energy policy

Because the report was prepared for the Natural Gas Council, readers should recognize that it reflects a gas-sector perspective. Even so, the core factual claims described in the source text point to a reality that many planners already accept: a gas-dependent grid requires a reliable gas delivery system if it is to remain stable in extreme weather.

The more difficult policy question is how to achieve that reliability without overrelying on assumptions that recent improvements are enough. The report's own conclusion argues against that mistake.

Its message is measured but consequential. Post-Uri reforms appear to have helped during Winter Storm Fern. Storage, winterization and operational flexibility mattered. But until those improvements endure a colder, more punishing event, the gas-electric system remains a work in progress.

For an electric grid increasingly asked to support economic expansion, digital infrastructure and weather resilience all at once, that is a warning worth taking seriously.
