Background

Section 202(c) of the Federal Power Act grants the US Department of Energy emergency authority to order electricity generation, transmission, or curtailment when a supply emergency threatens the grid. The DOE invoked the provision twice in 2026 specifically targeting behind-the-meter data-centre backup gas generation, a pattern that has recast a wartime-era statute as a tool for managing the power demands of hyperscale AI infrastructure .

Enacted as part of the Federal Power Act of 1935, Section 202(c) was originally designed for fuel-shortage or grid-stability emergencies, typically invoked during extreme weather or supply disruptions. behind-the-meter generation, where data centres run their own diesel or gas generators without drawing from the public grid, has created a novel application: large campuses can, in effect, opt out of grid constraints during peak demand. The Virginia Senate Finance Committee's proposed backup-generator fee is a parallel legislative response to the same dynamic.

The dual invocations in 2026 are significant because they establish that DOE treats data-centre BTM generation as a grid-emergency factor rather than a private operational matter. Each invocation opens a legal question about the scope of federal emergency authority over private generation assets, and the data-centre industry has pushed back on the interpretation. FERC has a supervisory role over Section 202(c) orders, adding a layer of regulatory complexity to each use. Ireland's EirGrid and SONI arrived at a comparable outcome by the opposite legal route: rather than invoking emergency, case-by-case powers, they wrote a 900 MW demand-loss ceiling directly into the standing grid code on 30 June 2026, live from July, curtailing behind-the-meter risk as a permanent rule rather than a one-off order.

Common Questions
What is Section 202(c) of the Federal Power Act?
Section 202(c) is a provision of the 1935 Federal Power Act giving the US Department of Energy emergency authority to order electricity generation, transmission, or curtailment when a supply emergency threatens the grid. In 2026 it was invoked twice against data-centre behind-the-meter backup gas generators.
Why did the DOE invoke Section 202(c) against data centres in 2026?
The DOE used its emergency curtailment authority under Section 202(c) to target behind-the-meter data-centre backup gas generation, treating it as a grid-emergency factor. Large campuses running private generators during peak demand can effectively opt out of grid constraints, which the DOE ruled a supply threat.Source: DOE emergency orders
How does behind-the-meter generation affect the power grid?
behind-the-meter generation lets large customers like data centres run their own generators without drawing from the public grid. During grid stress events this can distort demand signals and complicate grid management, which is why the DOE cited it as an emergency factor under Section 202(c).
What role does FERC have in Section 202(c) orders?
FERC has a supervisory role over Section 202(c) emergency orders issued by the DOE. Each invocation is subject to FERC review, adding a regulatory check on the DOE's emergency curtailment authority.
How does Ireland's approach to data-centre curtailment differ from the US Section 202(c) model?
The US DOE invokes Section 202(c) case by case, as an emergency order, against data-centre backup gas generation. Ireland's EirGrid and SONI instead wrote an equivalent 900 MW demand-loss ceiling directly into the standing grid code on 30 June 2026, applying the same curtailment logic as a permanent rule rather than a reactive emergency measure.Source: data-centres update 10
