Grid interconnection becomes a federal emergency, not a utility queue

After a directed FERC rulemaking on large-load grid interconnection missed its own deadline, FERC bypassed the normal rulemaking process and ordered every US grid operator to individually justify or fix its interconnection rules for data centers and other large loads.

On 23 October 2025, US Secretary of Energy Chris Wright invoked Section 403 of the DOE Organization Act to direct FERC to open a rulemaking on interconnecting large electricity loads, defined as 20 megawatts and above, a threshold covering most data center projects, to the interstate transmission system (Docket No. RM26-4-000), with a deadline of 30 April 2026 for final action. FERC did not meet that deadline with the originally contemplated rulemaking. Instead, following its 18 June 2026 open meeting, it took what it described as aggressive targeted action, issuing individual show-cause orders under Section 206 of the Federal Power Act to each US regional grid operator, requiring each one to justify why its existing open access transmission tariff's interconnection process for large loads remains just and reasonable, or revise it. On 16 July 2026, the Commission followed with a direction to the North American Electric Reliability Corporation to file new or revised reliability standards, due by 31 December 2026, addressing the operational risk of integrating large computational loads into the bulk power system.

The Signal

After a DOE-directed FERC rulemaking on large-load grid interconnection missed its 30 April 2026 deadline, FERC issued individual show-cause orders to every US regional grid operator on 18 June 2026, and on 16 July 2026 directed NERC to develop new reliability standards for computational loads by year end.

Why It Matters

This is a federal regulator treating grid interconnection delay for large loads, functionally data center demand, as urgent enough to bypass its normal multi-year rulemaking process and instead force each grid operator to individually justify its own tariff. Roughly 2,300 gigawatts of generation and storage capacity are currently stuck in US interconnection queues, more than the country's entire installed capacity, and the Department of Energy has estimated data centers will drive about half of an additional 100 gigawatts of peak demand needed by 2030. Interconnection, not capital or site availability, is now the binding constraint on how fast large-load projects can actually energize.

Capital Implication

Projects and funds underwriting data center or other large-load developments should treat interconnection timeline, potentially compressed by these orders, as a live regulatory variable to track state by state and grid operator by grid operator, not a fixed multi-year assumption baked into a financial model months ago.

Development Implication

Development geography for large-load projects is shifting toward wherever grid operators can demonstrate genuine interconnection capacity under this new show-cause scrutiny, reinforcing a pattern we have tracked all year: energy availability, more than land or capital, is starting to determine where large-scale development can actually happen.

What We Are Watching

  • Each regional grid operator's show-cause response and whether FERC accepts proposed tariff revisions or imposes its own.
  • NERC's reliability standards filing, due 31 December 2026, and what specific operational requirements it places on large computational loads.
  • Whether interconnection queue backlogs measurably shrink in the grid operators most affected by these orders, or whether the orders mainly accelerate paperwork without changing physical timelines.
