Trump administration declares power emergency in southeastern US as extreme heat strains grid

The Department of Energy issued an emergency order on June 24, 2025, allowing Duke Energy Carolinas to push selected generating units to maximum output as temperatures across North and South Carolina reached or exceeded 100°F.

The order, designated No. 202-25-5 under Section 202(c) of the Federal Power Act, temporarily permitted the utility giant to exceed air pollution limits. It was set to remain active until 10:00 PM ET on June 25, 2025, a narrow window designed to prevent what officials characterized as potential grid failures during a dangerous heat event.

What the emergency order actually does

Duke Energy Carolinas, a subsidiary of Duke Energy (NYSE: DUK), was the sole utility named in the order.

Section 202(c) of the Federal Power Act gives the DOE authority to order temporary measures when grid reliability is at immediate risk. This marked the latest in a series of DOE emergency measures during Trump’s presidency.

The bigger picture: a grid under pressure

The June emergency order sits within the framework of a much broader National Energy Emergency that President Trump declared on January 20, 2025, his first day in office. That executive order was designed to bolster domestic energy production and improve grid reliability in response to what the administration described as serious supply concerns.

The January declaration imposed a structured approach toward utilizing emergency authorities to maximize energy resource development. In practice, that has meant leaning heavily on existing fossil fuel generation capacity during moments of peak demand, exactly the kind of scenario that played out in the Carolinas.

What this means for investors

Duke Energy is the most directly relevant name here. As the entity specifically authorized under the emergency order, DUK stands to benefit from increased operational revenue during peak demand periods.

The Trump administration’s willingness to use emergency powers to keep fossil fuel plants running at full capacity, even at the expense of pollution limits, signals a policy environment that favors incumbent generators during crisis moments.
