Department of Energy

The US Department of Energy is a cabinet-level federal agency founded in 1977 under President Carter to advance energy technology and ensure nuclear weapons security. Secretary Chris Wright has used DOE's grid-security and Section 403 authorities to accelerate domestic energy development. Lawrence Berkeley National Laboratory, funded by DOE, is the canonical source for US data-centre energy consumption modelling. DOE's wider REMIT covers nuclear weapons, clean energy RD&D, and grid modernisation.

The DOE's grid-authority tools sit alongside, but do not supersede, FERC's independent rulemaking powers. Section 403 of the DOE Organisation Act provides the Secretary with a formal administrative mechanism to direct FERC rulemaking, used in October 2025 to open Docket RM26-4-000 on large-load interconnection standards. Deputy Secretary James Danly commended FERC's subsequent June 2026 commitment. The department's support for small modular reactor commercialisation also intersects with data-centre siting as hyperscalers pursue 24/7 carbon-free power alternatives to behind-the-meter gas.

The DOE's Energy Information Administration (EIA) publishes the Weekly Petroleum Status Report, the primary US crude inventory data series used by global oil traders and European benchmarks. The EIA's Short-Term Energy Outlook is the official US government crude price projection, widely cited alongside IEA and Goldman Sachs forecasts. In the context of European oil markets, EIA's weekly draw data and STEO projections are first-order inputs to Brent price formation.

The DOE's EIA is the primary source of US crude stock data that directly moves Brent and WTI benchmarks week to week. The EIA Weekly Petroleum Status Report for the week to 29 May 2026 showed a 7.97 million barrel draw, the sixth consecutive draw and the largest since February, putting US stocks 4% below the five-year average . These figures anchor the fundamental side of the Brent pricing debate even when geopolitical premia dominate. The EIA STEO for May 2026 projected Brent at $89/barrel in Q4 2026 , the lowest of the major forecast houses and a significant downside case for European oil importers.

The US Department of Energy inserted itself directly into the data-centre grid-connection dispute in October 2025 when Energy Secretary Chris Wright invoked Section 403 of the DOE Organisation Act to direct FERC to act on large-load interconnection standards. The DOE's preferred Deadline was 30 April 2026; FERC acted on 18 June 2026 by issuing Section 206 show-cause orders to all six US RTOs rather than a final rule, pushing a binding large-load standard to 2027 at the earliest. The DOE also commissioned Lawrence Berkeley National Laboratory to model US data-centre energy trajectories, providing the foundational research underpinning FERC's rulemaking. The department's Section 202(c) emergency curtailment authority was used twice in 2026 to curtail behind-the-meter data-centre generators in PJM territory, most recently via Order 202-26-06 on 18 May 2026. On 22 June 2026, Virginia passed a $0.011/kWh consumption tax on data-centre BTM generation (capped at $600m/year, sunsets 1 July 2028), becoming the first US state levy to tax the same BTM generation that DOE's curtailment orders have twice targeted in 2026.
