DOE curtailment order faces taking claim

Parties challenging the DOE's Section 202(c) curtailment order filed a rehearing on 28 May, calling it a physical and regulatory taking of property without compensation.

Key takeaway

The DOE 202(c) rehearing tests whether emergency curtailment counts as a compensable seizure of property.

Parties challenging the DOE (Department of Energy) Section 202(c) curtailment order, Order 202-26-06, filed a rehearing request on 28 May 2026 arguing it is "both a physical taking and a regulatory taking" of property without just compensation. The order is the same emergency authority that PJM now wields over backup-equipped data-centre generators . The petition lands at FERC (Federal Energy Regulatory Commission), where resolution is not expected before 2027.

This challenge borrows the constitutional weapon RCM Hill aimed at Hill County the same week, but the federal facts cut the other way. A construction moratorium stops a project that never started; curtailment reaches into a running facility and orders its operator to shed load on command, which is why the petitioners frame it as a physical seizure of generating equipment, not merely a limit on use.

The counter-argument rests on a century of utility law. Section 202(c) of the Federal Power Act lets the DOE compel generation and load-shedding during a grid emergency, and courts have long treated emergency curtailment as conditional regulatory power rather than a compensable taking. DOE lawyers argue a data centre running a backup generator accepted that reliability condition the day it interconnected. Whether FERC and the courts accept the seizure framing will set the price of every future emergency order against a data centre.

Deep Analysis

In plain English

The US Department of Energy has the power, under a law called Section 202(c) of the Federal Power Act, to order certain large electricity users to cut their power use during a grid emergency, like an extreme heat event. In May 2026, DOE used this law to allow PJM, the grid operator, to switch off backup generators at data centres if needed. Now, the companies affected are arguing that this is unconstitutional. They say the government is effectively taking their property, the backup generators they own, without paying them compensation. Under the US Constitution's Fifth Amendment, the government must pay fair value when it takes private property. The same constitutional argument appears in the Hill County case {{EVREF:/t/data-centres/2/twinsburg-and-ypsilanti-use-utility-hookup-denial/}}, making this a coordinated legal challenge across two different levels of government.

Deep Analysis
Root Causes

Section 202(c) of the Federal Power Act predates the data-centre era by nearly 90 years and was written for fuel-supply and physical-plant emergencies affecting public utilities. It grants the Secretary of Energy authority to order temporary generation and load-curtailment measures during a reliability emergency, but its legislative history contains no reference to private commercial buildings, behind-the-meter backup generation, or AI compute loads.

The absence of a settled statutory framework for managing large dispatchable private loads, precisely the gap that FERC's Docket RM26-4-000 is meant to close, forces the DOE to use emergency authority as a workaround.

The taking challenge will not resolve before 2027 because it depends on FERC's RM26-4-000 rulemaking establishing the permanent framework. Until that rule sets what obligations data-centre operators carry as a condition of grid connection, every 202(c) order is litigable as either an overstep of emergency authority or a regulatory taking of property that was never explicitly made subject to grid-control conditions in the first place.

What could happen next?
  • Risk

    A court ruling that repeated use of Section 202(c) for a structural load-management problem violates procedural requirements would force the DOE to pursue notice-and-comment rulemaking, removing emergency curtailment as a tool until a formal rule is in place, potentially through 2028.

    Medium term · Suggested
  • Precedent

    If the taking theory survives threshold review and reaches a damages assessment, it would set a price for all future grid emergency curtailments applied to private commercial buildings, changing the risk calculus for every future DOE 202(c) order.

    Long term · Suggested
  • Consequence

    Uncertainty over curtailment authority accelerates data-centre operators' investment in physical islanding, where a campus generates and stores its own power and reduces reliance on grid-connected backup, to remove the regulatory handle DOE is using.

NVIDIA told the Securities and Exchange Commission on 26 August it had signed memorandums aiming to mobilise over $500bn for buyers' equipment purchases, then said in the same filing the arrangements may not become definitive. It may also carry limited residual-value risk on the equipment itself.

IREN signed $2.4bn of financing on 25 August that only releases cash once its Mackenzie GPU servers are accepted, and only through 31 December 2026. A shipping delay from here now creates a funding problem as well as a revenue one.

Malaysia's Energy Commission recorded data centres at 9.3% of national power in one hot week in August, against a 7% year-to-date average, and is projecting 31% of peninsular demand by 2035. It wants roughly 9 GW of new gas-fired capacity by 2032 to cover the gap.

Singapore's EDB and IMDA rationed 200 MW across four operators on 21 August and followed with a tropical liquid-cooling standard six days later, fixing the terms before construction starts. The agencies will decide within 18 to 24 months whether to run a third call.

The Legal Resources Centre put the water and power draw of two approved Cape Town Equinix sites in public, at roughly 4.4 billion litres and 1.4 to 1.5 billion kWh a year, because the city and the operator would not. It wants a cumulative assessment before any more of the five approvals proceed.

Brazil's energy ministry published Redata's five conditions after the Senate passed PL 278/2026 on 1 September, betting a repeatable annual water test enforces cooling design better than a one-off approval. Redata now needs President Lula's signature before any of it takes effect.
