Data Centers & Large Loads

If a data center buys land near you outside a municipality or industrial park, it must notify you by certified mail within 60 days. Failing to do so carries a $1,500 per day penalty.

The provision that affects neighbours

This is the part of the 2026 law most relevant to rural landowners, and the part least reported.

A large load customer, or any developer, owner or entity acting on its behalf, that buys land in Oklahoma outside an industrial development park or a municipality must notify:

• the Oklahoma Corporation Commission
• the county commissioners of the county where the land is
• and every adjacent property owner whose land abuts the purchase.

Notice is due within 60 days of the purchase, by certified mail, return receipt requested, to the last-known business or residential address.

What counts as a large load customer

New data centers, new cryptocurrency mining operations, and new facilities whose primary function is artificial-intelligence computing, that contract to add 75 megawatts or more per facility or in aggregate behind a single point of interconnection, for load added after July 1, 2026.

The definition expressly excludes residential, commercial, agricultural and industrial ratepayers, and entities building generation for behind-the-meter projects.

The ratepayer side

Electric suppliers must maintain separate terms, conditions and tariffs for large load customers, including credit requirements and recovery of costs that would otherwise be stranded if the customer leaves or materially cuts load. The minimum term of service is ten years.

Rate-setting bodies must ensure residential, commercial and industrial customers are protected from unjust rates resulting from serving large loads, with costs allocated by cost causation: the customer who causes the cost bears it.

This applies to all retail electric suppliers: investor-owned utilities, cooperatives, municipal utilities and public power.

Where Oklahoma data centers are located

There is no single Oklahoma government database that maps every data center, colocation facility and proposed hyperscale project in the state. No agency is charged with keeping one. What exists instead is a set of partial sources that each count something different.

Google's Oklahoma footprint

Google publishes its own Oklahoma locations, which makes it the most reliable source for its own projects and no guide at all to anyone else's.

Mayes County

Operating · Announced 2007, expanded in 2012, 2015 and 2019.

Muskogee County

In development

Stillwater

In development

Google reports investing more than $15 billion in Oklahoma since the Mayes County data center was established in 2007. That figure is Google's, it covers Google, and it should not be read as the size of the Oklahoma data center industry.

Google's state page and its global location directory carry different cumulative investment figures. We use the figure published on the Oklahoma page and link both rather than reconciling them.

Where development activity is reported

County level, not parcel level. This map is orientation. It does not show property boundaries, ownership, or the site of any particular facility, and it is not a substitute for county records.

Marked counties are those with activity reported by the sources named above as of August 2026. A county that is not marked may still have development that no public source has recorded yet.

Current snapshot

Cleanview project tracker, read August 2026. These figures change; open the tracker for the current database.

The tracker also displays a combined total that does not equal the operating and planned figures added together. We publish the two categorised figures it states and leave the discrepancy to the source rather than inventing a category to explain it.

Why location matters to landowners

Whether a project sits inside a municipality or out in the county changes which office you are dealing with, and in some cases whether you are entitled to notice at all.

• Notice to adjacent owners. The 60-day certified mail requirement in § 906 applies to land bought outside a municipality or an industrial development park. Inside either, it does not.
• County commissioners. They receive the statutory notice and they enforce the penalty. For rural projects they are the office to contact.
• Transmission and substations. Large loads need lines and substations, which can mean easements and condemnation across land some distance from the facility. Transmission siting runs through the Corporation Commission under a separate act.
• Groundwater and cooling. Cooling water is regulated by the Water Resources Board, and the rules change on November 1, 2026.
• Roads and haul routes. Construction traffic is a county road question, handled by your county commissioners.
• Municipal versus rural siting. Zoning, if any applies, is local. Many Oklahoma counties have no county-wide zoning.
• Land acquisition. Purchase offers and option agreements near an announced project are a title and contract matter. Records are at the county clerk.

Whether data center development is good or bad for a community is a judgment for that community. What this page tries to do is make it possible to work out which agency, which statute and which record actually governs each piece of it.
