FERC / Docket RM26-4-000 / June 18 vote / cost allocation for >20 MW loads
FERC committed in April to vote by end of June on Docket RM26-4-000 — the rulemaking on how 'large loads' (anything over 20 MW, which covers essentially every serious data center) interconnect to the interstate transmission grid, with the June 18 open meeting the expected vote date — and FirstEnergy filed on June 5 asking FERC to require data centers to pay for the transmission upgrades they trigger
Plain-English version of what FERC is and why this matters: the Federal Energy Regulatory Commission (FERC) is the federal body that approves the rules governing the interstate transmission grid — the high-voltage lines that move bulk power between states. State public utility commissions (the PUCT in Texas, the SCC in Virginia, etc.) regulate the distribution layer underneath. A new data center over ~20 MW pulls so much power that connecting it usually requires transmission-level upgrades — new substations, line rebuilds, sometimes new generation. The question FERC is being asked is who pays for those upgrades: the developer requesting the load, the utility's other ratepayers (residential households and small businesses), or some split. The proceeding (Docket RM26-4-000) was triggered in October 2025 when Energy Secretary Chris Wright invoked a rarely-used authority under the DOE Organization Act and formally directed FERC to consider new interconnection rules for large loads. FERC committed in April to act by end of June. The June 18 open meeting is the expected vote. The most concrete recent signal is FirstEnergy's June 5 filing, which explicitly asked FERC to require data centers to pay for the transmission upgrades needed to bring them online — exactly the position the state ratepayer-protection bills (NY, OK, the Abbott directive in Texas) are trying to legislate at the state level.

Why it matters
This is the single most important federal docket of the year for site readiness. Three downstream consequences to track. (1) If FERC adopts cost-shifting onto the requesting load, the state ratepayer-protection bills become redundant in their main goal and pivot to the harder questions (community benefits, water, noise), while site selection has to start carrying a federal interconnection-cost line item that doesn't exist today. (2) If FERC formalizes co-location, the Behind-The-Meter pathway becomes federally blessed instead of legally murky — that directly expands the BTM SKU surface Cliff is sized around. (3) Whatever FERC says about federal-vs-state jurisdiction is the part that will get litigated, and the litigation outcome is what actually matters for two to three years. The corpus needs to ingest the order text the moment it drops and tag every state proceeding that cites or relitigates it — the value of a regulatory graph compounds the most around new federal anchors, because every state docket below it will reference back.
