Imagine a winter storm so severe that it exposes the fragility of an entire nation's power grid. That's exactly what happened during Winter Storm Fern, where a staggering 21 gigawatts of power generation vanished into thin air—or rather, into the freezing temperatures. This isn't just a story about a storm; it's a wake-up call about the reliability of fossil fuels in the face of extreme weather.
Winter Storm Fern has become the latest—and most chilling—evidence that America's power grid cannot depend on fossil fuels for consistent energy, especially when temperatures plummet. In the heart of this crisis was PJM Interconnection, the nation’s largest power grid operator. Here, fossil fuel power plants were forced offline due to limited natural gas supplies and bone-chilling cold. By Sunday afternoon, PJM reported that nearly 21 gigawatts of generation—roughly 16 percent of the grid’s afternoon demand—was offline. But here's where it gets controversial: What if the very fuels we rely on are the ones letting us down when we need them most?
Power market operators typically don’t disclose which plants go offline or what type of fuel outages occur during extreme weather until long after the storm has passed. However, our analysts dug into the data, and the results are clear: Fossil fuels failed during Fern. On January 24th, the day before the storm, PJM’s gas generation peaked at 60 GW during the evening. But on January 25th, the day of the blizzard, gas generation dropped to 50 GW, even as prices remained sky-high across the region. Expensive oil generators tried to fill the gap, but the system was already strained.
The picture becomes even clearer when examining data from January 26th. According to GridStatus.io, during the 8:00 a.m. peak demand, gas-burning generation was down 10 GW, coal-fired generation was down 2 GW, and oil-burning generation was down 3 GW—all compared to the same time on January 24th. And this is the part most people miss: This isn’t an isolated incident.
History has shown that fossil fuels struggle in cold weather. During the 2021 Texas blackouts caused by Winter Storm Uri, frozen gas pipelines and compressors cut off fuel supplies, while gas-burning plants couldn’t operate in the extreme cold. Coal plants fared no better—multiple coal-burning power plants were knocked offline for over 24 hours, and frozen coal piles locked up fuel supplies. The same issues plagued Texas during a 2011 blackout, leaving millions without power. Is it time to ask: Are we placing our trust—and our energy security—in the wrong hands?
Contrast this with today’s advancements: Texas now has enough battery capacity to cover nearly 20 percent of its all-time demand record, a dramatic shift from the near-zero capacity during the 2021 blackouts. Yet, we still don’t fully understand why PJM’s fossil fuel plants failed during Winter Storm Fern, though gas supply issues are already emerging as a key culprit. Fox Business highlighted that the strain on the grid is rooted in the nation’s heavy dependence on natural gas delivery, noting that any disruption to pipelines can quickly jeopardize power generation.
Interestingly, while PJM has limited renewables in its mix, the wind and solar systems that were online performed admirably, producing almost 7 percent of the region’s electricity—higher than the day before the storm. But here’s the real question: Why are we doubling down on fossil fuels when they consistently fail us?
The U.S. Department of Energy’s pro-fossil fuel policies are part of the problem. Coal plants break down more frequently than any other generation source, yet the DOE continues to force coal-fired plants to stay open past their planned retirement dates. This only adds the least-reliable supply to the grid, even when these plants are already malfunctioning or costing consumers hundreds of millions to keep running.
Increasing America’s reliance on natural gas, despite constrained supply routes and record exports to foreign markets, makes communities more vulnerable to frozen pipelines and supply shortages. As Didi Caldwell, CEO of Global Location Strategies, told Fox Business, “Adding more natural gas generation will not fix and may exacerbate the risks.” Is this a risk we’re willing to take?
Customers are also paying the price for volatile gas prices. Natural gas prices soared 59 percent the week before Winter Storm Fern, on top of a 59 percent increase between 2024-2025, with another 14 percent jump expected in 2026. But what if there’s a better way?
True grid reliability, especially during extreme weather, requires a different approach: strengthening our transmission systems, deploying solar-plus-battery systems, expanding onshore and offshore wind power—which historically perform better in winter storms—and increasing energy efficiency measures to prevent demand spikes when temperatures drop.
So, what do you think? Are fossil fuels still the answer, or is it time to embrace a more resilient energy future? Let’s hear your thoughts in the comments.
