FERC moves to rewrite how data centers connect to the power grid

FERC moves to rewrite how data centers connect to the power grid

Rule Changes

A federal rulemaking decides who pays for grid upgrades and how fast AI data centers get power

Today: FERC acts on the rule

Overview

For decades, the cost of upgrading the power grid was spread across everyone's electric bill. On June 18, the Federal Energy Regulatory Commission (FERC) acted on a rule that could put much of that cost on the data centers that trigger it.

The rule sets national terms for plugging giant electricity users into the interstate grid. It decides how fast they connect, who pays for new wires, and whether Washington or the states call the shots. The outcome shapes electricity bills and AI buildout for years.

Why it matters

How fast AI data centers get power, and whether their grid costs land on your electric bill or theirs, now turns on this federal rule.

Key Indicators

20 MW
Large-load threshold
Demand above 20 megawatts would fall under the proposed federal rules.
100%
Participant funding
Share of triggered grid-upgrade costs the proposal would put on the large load itself.
60 days
Proposed study window
Target time to complete an interconnection study for flexible loads willing to curtail.
30–300 MW
Threshold range debated
Range commenters proposed instead of 20 MW, to avoid sweeping in midsize factories.

  1. FERC acts on the rule

    Today Regulatory

    At its monthly open meeting, FERC took up the large-load docket, moving a national framework for data-center grid connections from proposal toward execution.

  2. FERC commits to a June deadline

    Process

    FERC issued an order saying it intended to deliver a legally durable order on the docket by the end of June 2026.

  3. Public comment deadline

    Process

    Utilities, states, manufacturers, and tech firms filed comments. They split over the 20 MW threshold, cost allocation, and federal authority.

  4. DOE directs FERC to act

    Directive

    Energy Secretary Chris Wright used a rare statutory power to direct FERC to write rules speeding large-load connections. A draft proposal came attached.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

July 2011

FERC Order 1000 (2011)

FERC required regions to plan transmission together and to allocate the cost of new lines to those who benefit. States and utilities objected that the agency was dictating how local grids get built and paid for.

Then

Dozens of parties challenged the rule in court.

Now

A federal appeals court upheld it in 2014, cementing FERC's role in regional cost allocation.

Why this matters now

The current fight is again about who pays for grid upgrades. Order 1000 shows FERC can win cost-allocation battles, but only after years of litigation.

January 2016

FERC v. Electric Power Supply Association (2016)

The Supreme Court reviewed a FERC rule paying electricity users to cut demand. Challengers said FERC had crossed into retail markets reserved for states. The Court disagreed, 6-2.

Then

The ruling let FERC keep regulating demand response in wholesale markets.

Now

It set the boundary for how far FERC can reach toward the customer side of the meter.

Why this matters now

The large-load rule tests that same line. This case is the precedent both sides will cite on whether FERC can regulate big loads.

September 2020

FERC Order 2222 (2020)

FERC ordered grid operators to let small, distributed resources like home batteries compete in wholesale markets. States and utilities warned it intruded on their control of local distribution systems.

Then

Grid operators spent years rewriting market rules to comply.

Now

Implementation is still rolling out region by region, slowed by the federal-state seam.

Why this matters now

Like the large-load rule, Order 2222 pushed federal authority toward resources states had managed. It shows how slow these national frameworks are to take effect.
