Wartime Switch Flipped To Keep Lights On

Electricity and gas bills with a red upward arrow — HEAT CRISIS ESCALATES

As triple-digit heat baked the country, Washington quietly pulled a wartime lever to keep America’s lights on.

The Department of Energy used emergency powers to stretch the grid through a brutal 2025 heat wave.
Coal and oil plants were ordered to run harder and longer than normally allowed to avoid blackouts.
Trump’s earlier national energy emergency and executive order set the legal stage for this response.
Environmental groups now claim the “emergency” is a cover to keep aging fossil plants alive.

How a scorching summer pushed the grid to the edge

The June 2025 heat wave did exactly what experts have warned for years: it slammed an aging grid with record air-conditioning demand, on top of new load from data centers and electric cars.

In the Southeast, Duke Energy Carolinas warned of a potential shortfall as temperatures approached or topped 100 degrees in parts of the Carolinas.

Federal officials faced a simple choice that families understand very well: sweat in the dark or run every megawatt they could find, even from plants usually dialed back for pollution limits.

The Department of Energy responded by issuing an emergency order to Duke Energy under Section 202(c) of the Federal Power Act, a provision enacted during the New Deal to address wartime power problems.

The order let specific plants in the Carolinas run at maximum output for a two‑day window, even if they exceeded emissions limits in their operating permits. The goal was blunt and old‑fashioned: keep the air conditioners humming and prevent rolling blackouts as demand spiked into the evening.

The legal playbook behind the “power emergency”

This heat wave order did not come out of thin air. On January 20, 2025, President Trump declared a National Energy Emergency, arguing that years of policy had left the United States with “inadequate and intermittent” energy and a less reliable grid.

In April, he signed an executive order titled “Strengthening the Reliability and Security of the United States Electric Grid,” directing the Department of Energy to lean on Section 202(c) to keep “critical” power plants running when regions were deemed “at risk.”

Congress’ own research arm later noted that the Department of Energy’s 2025 emergency actions reflected “seemingly new interpretations” of Section 202(c), stretching a tool once used rarely into a more active reliability backstop.

The July 7, 2025 resource adequacy report, required by that executive order, introduced a national method to flag regions such as PJM in the Mid‑Atlantic and the Midwest system as high‑risk if retirements and new demand became out of balance.

In short, the legal track was laid months before the heat wave hit; the Duke order was the first big train to run on it.

From the Southeast to the Mid‑Atlantic: emergency powers go regional

Once Section 202(c) came off the shelf, it did not remain in a single state. After the Southeast order, the Department of Energy issued a series of emergency directives through the summer to manage grid stress.

A July order empowered the Mid‑Atlantic grid operator PJM to dispatch backup generation at large data centers and industrial sites as a last‑resort tool to ease system pressure, and to keep certain fossil fuel units ready even when environmental rules would normally limit them.

By August 2025, the agency had extended multiple critical reliability orders, keeping coal and oil‑fired units online longer in places like Puerto Rico, Michigan’s Campbell plant, and the Eddystone peaker units in Pennsylvania.

A separate order, effective July 28 through October 26, was framed as necessary to “safeguard” the Mid‑Atlantic grid, underscoring how worried officials were about losing legacy plants before new capacity and transmission arrived.

The clash: real emergency or “false alarm” for fossil fuels?

Environmental advocates saw something very different. Earthjustice blasted the August extensions as an effort to “extend the lives of polluting power plants under a false energy emergency,” arguing that the administration was using crisis language to dodge normal environmental protections and slow the transition away from fossil fuels.

Their concern tapped into a long‑running fear on the left: that emergency powers become a back door to favor chosen industries when markets would otherwise close plants.

The Department of Energy, for its part, did not release detailed real‑time data about reserve margins or frequency stress during the June heat wave, at least not in a way the public could easily verify.

Critics seized on that gap, saying if the emergency was as serious as advertised, then the technical case should be easy to publish.

What this reveals about a grid caught between old and new

Behind the legal citations and press releases sits a deeper problem. The Department of Energy’s own resource adequacy work warns that rising electricity demand, driven by heat waves, data centers, electric vehicles, and electrified industry, is on track to outstrip supply in several big regions if retirements continue as planned.

A recent study in major U.S. cities found that when heat waves overlap with grid failures, up to the entire urban population can face dangerous indoor heat exposure. Losing power during extreme heat is not a lifestyle inconvenience; it is a life‑and‑death risk.

That is why many state regulators and grid experts talk less about emergency orders and more about long‑term resilience: new transmission lines, modern planning for reserve margins, and a realistic mix of resources that can perform when the weather is off the charts. In that bigger picture, the 2025 emergency looks like what it is: a short‑term patch on a system that has not kept up.

A serious country does not gamble its people’s safety on wishful thinking. It generates enough reliable power, hardens the grid, and uses emergency powers only when all else fails —and transparently.
