Department of Energy

US federal agency; issued its third 2026 grid-curtailment order as EIA slashed its Brent forecast.

On 18 May, the Department of Energy authorised PJM to curtail data centres with backup generation during a heat emergency, placing a federal agency at the centre of the US grid-load dispute.

Background

The Department of Energy is the US Cabinet-level agency responsible for energy policy, nuclear weapons security and grid reliability. Its recent relevance lies in the authority to intervene when power supplies are short, including Section 202(c), which it used for PJM during the 18 May 2026 heat emergency.

Created in 1977, the department combines civilian energy policy with national-security responsibilities. It can also direct the Federal Energy Regulatory Commission on specified rulemakings under Section 403, giving it influence over how large electricity loads connect to the interstate grid.

Its Energy Information Administration is a separate statistical Arm that publishes US oil-market data and forecasts. On 9 September 2026, the EIA pushed its estimate of Middle East oil-output recovery to mid-2027 after raising its forecast for fourth-quarter shut-ins.

Grid curtailment

DOE curtails data-centre power

On 18 May 2026, the Department of Energy gave PJM emergency authority to curtail data centres operating private gas turbines during a heat event. The order made behind-the-meter generation available to the grid operator, reversing the assumption that private power insulated large campuses from grid constraints.

By 4 August, PJM had proposed a standing rule for electricity users drawing 50 MW or more, replacing temporary emergency action with a connection condition from June 2027. For the Department of Energy, the proposal marks a possible shift from case-by-case use of Section 202(c) towards a permanent grid-reliability framework.

Common Questions

Reference

Who is Chris Wright and what is his role at the DOE?
Chris Wright is the US Secretary of Energy, confirmed in January 2025. He directed FERC to act on large-load grid connections in October 2025 and has positioned AI data-centre infrastructure as a national priority.Source: DOE
What is the US Department of Energy's role in oil market data?
The DOE's Energy Information Administration publishes the Weekly Petroleum Status Report and the Short-Term Energy Outlook, the primary US government data series driving Brent and WTI price formation.Source: EIA
What is Section 403 of the DOE Organisation Act?
Section 403 allows the Energy Secretary to formally direct FERC rulemaking. Secretary Chris Wright used it in October 2025 to open the large-load interconnection docket RM26-4-000.Source: DOE Organisation Act
What happened when FERC acted on its June 2026 large-load grid deadline?
On 18 June 2026, FERC issued Section 206 show-cause orders to all six US regional transmission organisations rather than the binding final rule the DOE's Section 403 direction had sought. Responses are due 17 August; a final standard is not expected before 2027.Source: FERC
Why did the Department of Energy get involved in data-centre grid connections?
The DOE invoked Section 403 authority to direct FERC to standardise how large loads connect to the US transmission grid, driven by the view that AI data-centre infrastructure is a national economic and competitiveness priority.Source: FERC announcement
Why did the Strait of Hormuz reopening change the DOE's oil price outlook?
A US-Iran Ceasefire reopened the strait of Hormuz, allowing previously shut-in crude production and trade flows to resume. The EIA expects worldwide output to return to near pre-conflict levels by early 2027, which is why its Short-Term Energy Outlook cut its Brent forecast sharply in July 2026.Source: EIA
How many emergency curtailment orders has the DOE issued against data centres in 2026?
Three. Energy Secretary Chris Wright signed a Section 202(c) order on 18 May 2026 granting PJM curtailment authority, followed by two more orders covering 30 June to 3 July that let PJM force large customers onto backup generation within 15 minutes of an emergency signal during summer heatwaves.Source: DOE / New Jersey Monitor
What is the EIA's latest Brent crude oil price forecast for late 2026?
The EIA's July 2026 Short-Term Energy Outlook cut its Q4 2026 Brent forecast to $70/barrel, down 14-18% from the prior month's projection of roughly $89, after a US-Iran Ceasefire reopened the strait of Hormuz and let shut-in oil production return to market.Source: EIA Short-Term Energy Outlook, July 2026
What does the EIA Weekly Petroleum Status Report show about US oil stocks?
The EIA's report for The Week to 24 July 2026 showed US commercial crude stocks at 404.5 million barrels, down 7.2 million barrels week-on-week and about 7% below the five-year average. Refinery utilisation stood at 97.2%, and distillate stocks were about 10% below the five-year average.Source: EIA Weekly Petroleum Status Report
