In one sentence. On 2026-06-18 FERC issued Federal Power Act Section 206 show-cause orders to all six US RTOs and ISOs (dockets EL26-67 through EL26-72), giving each 60 days to justify or reform large-load interconnection rules across five areas including co-location, behind-the-meter generation and cost-shifting.

Why it matters

Interconnection queues and siting permission now set the pace of compute supply more than chip availability does. That relocates strategic advantage to whoever holds existing grid rights, and it makes a regulatory body with no AI mandate the most consequential regulator in the sector.

What is happening

On 2026-06-18 FERC issued Federal Power Act Section 206 show-cause orders to all six US RTOs and ISOs (dockets EL26-67 through EL26-72), giving each 60 days to justify or reform large-load interconnection rules across five areas including co-location, behind-the-meter generation and cost-shifting. Capacity is now disclosed in gigawatts rather than GPUs: CoreWeave reports 1.5GW live and 4.2GW contracted; Nebius expects about 5GW contracted by year-end; Microsoft targets 38GW by 2032 from roughly 12GW today.

First observable signal. FERC's advanced notice of proposed rulemaking on large loads, responding to an October 2025 DOE directive; concluded in about eight months with over 3,500 pages of comments.

Evidence

Companies and products

Companies. CoreWeave, Nebius, Microsoft, Oracle, Meta, PJM Interconnection, ERCOT
Products. Grid interconnection agreements, Co-location and behind-the-meter generation, Large-load transmission service
Funding. Capital flows through data-centre development rather than venture rounds. Pentagon Office of Strategic Capital reportedly in talks to lend Fluidstack $5B.

Impact

Industry. Beneficiaries: Incumbents with existing interconnection rights, Gas turbine and on-site generation suppliers, Regions with spare headroom. Losers: Late entrants facing multi-year queues, Ratepayers if cost allocation shifts to them.
Consumer. Deployment is concrete and measurable in GW: 1.5GW live at CoreWeave alone, with 4.2GW contracted.
Regulatory. Very high and direct. FERC Section 206 proceedings can compel tariff changes across all six US organised markets, including cost allocation that determines who pays for large-load interconnection.
Geography. US, EU

Risks and counter-forces

• Cost-allocation rulings could raise data-centre power costs sharply
• Local opposition is producing project withdrawals
• Political reversal risk at both federal and state level

Counter-trends. On-site generation and behind-the-meter arrangements that bypass the queue, Siting in less constrained regions and overseas
