Federal regulators approve a new process letting data centers connect to the power grid in 90 days, doubling the fees to use it

On January 14, 2026, the Federal Energy Regulatory Commission approved a new tariff filed by the Southwest Power Pool, the grid operator serving parts of 15 central states, creating a faster review path for large power users such as data centers paired with their own new generation. Nearly 6 gigawatts of these large loads had already asked to connect before the faster process existed.

How fast can a data center connect to the power grid

How fast can a data center connect to the power grid. On January 14, 2026, the Federal Energy Regulatory Commission, the federal agency that regulates the power lines that cross state lines, approved a new review process built by the Southwest Power Pool, the grid operator that plans and runs the shared power grid across all or part of 15 states in the middle of the country. The order took effect January 15, 2026, under docket ER26 247. The filing creates a category the grid operator calls a High Impact Large Load, a new facility that needs 50 megawatts or more of power, a megawatt being a unit that measures how much electric power a facility can draw at once, or as little as 10 megawatts if it connects to a line rated at 69 kilovolts or below, a kilovolt measuring the voltage of the line itself. Data centers and factories are the examples the grid operator itself gives.

90 days to study a large load, longer if a restudy is needed

Under the new process, the grid operator studies and approves a High Impact Large Load that is paired with new power generation built on site or nearby, in an initial 90 days. The full study can run to 150 days if a restudy is needed, a total FERC itself used when comparing this path to the older, slower one. Before this process existed, nearly 6 gigawatts worth of these large loads had already asked to connect to the grid in 2024, a backlog the faster process is meant to work through.

The 30 day compliance filing deadline comes from the release the Southwest Power Pool itself published, source 1. The 90 day initial study and the 30 to 60 day restudy window come from source 4. The 150 day total matches the single figure source 2 states FERC itself used to compare this process against its older, slower one.

The release the Southwest Power Pool itself published states the grid operator must file compliance paperwork within 30 days of the order for minor procedural matters, a detail read directly from that release rather than repeated from other coverage.

A faster answer costs more to ask for

The new process also charges more to use. Fees and study deposits under the new process are double those charged under the standard process the grid operator already runs, called DISIS. For the largest requests, over 500 megawatts, the deposit can reach 500,000 dollars, against 250,000 dollars under the old rules.

Southwest Power Pool chief executive officer Lanny Nickell said the approval places the grid operator ahead of the rest of the country.

We're proud SPP is the first in the nation to incorporate transmission, generation and load interconnection services into a single framework.

It's essential to our nation's competitive future that we can quickly, reliably and affordably meet vastly increasing energy demands.

FERC is not done widening the path

FERC did not stop with the January order. In June 2026 it approved a follow on Southwest Power Pool service called Conditional High Impact Large Load Service, letting a large load connect and start drawing power on a non firm basis, subject to being cut off during grid emergencies, for up to 7 years while it waits for full, uninterrupted service and the grid upgrades its connection requires.
