Data Center Site Selection in Oklahoma

In Oklahoma, the parcel’s service territory usually decides the counterparty. Three providers dominate large-load conversations, and each has a different model:

Oklahoma Gas and Electric (OG&E) and Public Service Company of Oklahoma (PSO) are investor-owned and rate-regulated, so their large-load terms run through Corporation Commission dockets.¹ The Grand River Dam Authority (GRDA) is a state public power agency, and most of the roughly 80 companies at MidAmerica Industrial Park are its electricity customers.¹⁰ Rural cooperatives and municipal systems also serve parts of the state; the ownership model shapes how a request is handled.

All of them sit in the Southwest Power Pool, so regional transmission planning and large-load study rules come from SPP rather than the state. That two-layer structure (state tariff plus regional study) is the core of any Oklahoma power screen. Our SPP site selection guide covers the regional market in more depth.

Governor Kevin Stitt signed House Bill 2992, the Data Center Consumer Ratepayer Protection Act of 2026, in May 2026.¹ Its central requirement is structural: electricity suppliers must create separate terms and conditions for large-scale customers such as data centers and cryptocurrency mining operations, so that the costs those loads create are not spread across residential and small business bills.¹

The bill’s sponsor, Rep. Brad Boles, described two financial protections. Large-load customers would sign contracts to pay for their infrastructure costs over 10 years, and they would post collateral so that a utility is covered if a customer leaves before that contract is paid off.¹¹ He said existing large-load customers with ongoing contracts would not be affected.¹¹

The law also reaches land. Developers of qualifying projects must notify adjoining landowners, county commissioners and the Corporation Commission within 60 days of acquiring land, and Oklahoma Voice reported that missing that window carries a $1,500 daily fine.⁶ The law took effect July 1, 2026.⁶ For landowners, that means a sale or option agreement for a large data center is likely to become public sooner than in many states, so confidentiality terms and neighbor relations need planning from day one.

PSO filed its large-load tariff with the Corporation Commission before HB 2992 was signed, and a PSO spokesperson said it aligns with the bill’s goal of keeping prices tied to the cost of serving each customer group.¹ OG&E followed in mid-June 2026.² OG&E’s proposal would apply to new customers planning at least 75 MW, and to existing customers that add 75 MW or push their demand past 125 MW.²

The proposal includes billing minimums, early termination and capacity reduction fees, and financial collateral.⁷ Data centers would cover their own grid connection costs.¹² A new monthly fee could raise an estimated $25 million to $30 million a year that might later fund credits for residential or vulnerable customers, though any credit would need Commission approval in a rate case.¹² OG&E expected a review of roughly six months once the Commission set a schedule.²

For siting, the practical effect is that a 75 MW-plus campus in OG&E territory should be underwritten as a long-term, take-or-pay style commitment. A ramp schedule that overstates early demand becomes expensive under billing minimums. Final terms may change in the docket, so treat the filed version as a planning case, not a price.

MidAmerica Industrial Park, between Pryor and Chouteau in Mayes County, covers about 9,000 acres and hosts nearly 80 companies.¹⁰ The park was created in 1960, and Google, which announced its Oklahoma plans in 2007, opened its first data center there four years later.³ GRDA’s Grand River Energy Center sits on the park’s southern edge and supplies much of the electricity used by park tenants.¹⁰

In August 2025, Google announced a $9 billion investment in Oklahoma over two years, covering expansion at Pryor and a new campus in Stillwater.¹³ The Pryor pattern (a large, publicly controlled industrial park with an on-site generation source, existing transmission and a long-standing anchor tenant) is the model many Oklahoma communities are now trying to copy.

Sites in and near a mature park usually screen well on power, roads and entitlement, but the best-served tracts are often already spoken for. For land outside the park, the questions are distance to GRDA, OG&E or PSO transmission, whether the local substation has headroom, and whether a utility will commit to serve on the developer’s timeline.

Google’s newer Oklahoma sites are in OG&E territory. On April 30, 2026, OG&E announced a contract to serve three Google data centers in Muskogee and Stillwater, with load rising to as much as 1 GW over five years and peak demand expected to reach 1.2 GW by 2036.⁴ Google pays 100% of its grid connection costs and its share of generation, and pays contracted costs whatever its actual energy use.¹⁴ The contract includes minimum billing and early-exit penalties, and Google is building two solar farms whose capacity OG&E will make available to the data centers.⁴ The agreement still required Corporation Commission approval.⁴

In Stillwater, the planning commission approved a final plat covering three industrial lots totaling 202 acres, which still required City Council acceptance before recording with the Payne County Clerk.¹⁵ Near Owasso, Google was revealed as the company behind Project Clydesdale, a 506-acre campus approved by county commissioners in September 2025.¹⁶

These projects show the scale utilities are now planning around. They also mean that the first large blocks of new capacity in some areas are committed. A parcel near one of these campuses can benefit from new transmission, or it can find itself behind a hyperscaler in the queue. Ask the utility directly which is true; see our guide to power timelines and queues.

On January 14, 2026, FERC unanimously accepted SPP’s rules for High Impact Large Loads (HILL) and the related generation assessment (HILLGA) in Docket No. ER26-247.⁸ HILL rules apply to loads of 50 MW or more, or 10 MW at lower voltages, and HILLGA is an optional, expedited study track for pairing new generation with a HILL.⁸ Projects that provide their own energy or connect to new or existing generation can use a 90-day study-and-approval process.⁵

SPP has said a common use case is a combustion turbine or combined-cycle plant built next to a large data center, and that several such plans are under way in Oklahoma; as of January 2026, 12 large-load projects in the state were in SPP’s queue.⁵ State law also helps: Senate Bill 480 lets companies that produce their own power avoid state utility regulation, but only for natural gas generation.⁵ That puts gas pipeline access near the top of the screen for gigawatt-scale Oklahoma sites, alongside the on-site generation options it enables.

Oklahoma’s Department of Commerce describes a sales tax exemption on machinery and equipment for businesses primarily engaged in computer services and data processing that earn at least 80% of annual gross revenue from out-of-state buyers; it does not cover electricity.⁹ The same summary says data centers under certain other industry codes may qualify for an exemption on personal property purchases, including electric power, computers and servers.⁹ Which path applies depends on the operator’s business, so confirm with a tax advisor and the Oklahoma Tax Commission, and compare with our sales tax exemptions by state.

1. 01Confirm the serving utility: OG&E, PSO, GRDA, a cooperative or a municipal system.
2. 02Check whether the load crosses 75 MW and model the filed tariff’s minimums, collateral and 15-year term.²⁷
3. 03Plan the 60-day land acquisition notice and community outreach.
4. 04Decide whether to pair generation and use SPP’s HILL path, and test gas supply.⁵⁸
5. 05Check nearby hyperscale commitments that may use local capacity first.
6. 06Confirm sales tax eligibility for the actual operator.

Most of this can be checked from public filings before an option is signed. Our methodology explains how we work through it, and you can get a site reviewed to test a specific parcel. Neighboring markets with different rules are covered in our Texas and Kansas guides.
