Cheyenne and Arapaho Tribes' Three-Year Data Center Ban Lands Amid a Statewide Run of Oklahoma Pauses

A $200 million offer, declined

Governor Reggie Wassana told KGOU on September 30, ahead of that weekend's vote, that a data center agreement could have generated roughly $200 million a year for the tribes, a figure he raised as the economic case against the moratorium. Tribal members voted it down.

"Water is our way of life," tribal member Christine Levi said, according to KOSU's October 5 report. "If we don't protect our lands, who's going to?"

The resolution language itself framed the vote in similar terms, describing Cheyenne and Arapaho Tribal members as "natural environmentalists" and citing the need to study AI-specific impacts before any permanent legislation, KGOU reported. Tribal member Patrick Kincaid pressed the practical version of the same concern at a related meeting, asking, "How do we move forward with such a massive amount of consumption of water?" according to Oklahoma Energy Today's October 4 account. Other members at that meeting demanded full transparency in any future dealings and a prohibition on non-disclosure agreements, the outlet reported.

Oklahoma Energy Today's reporting places the Cheyenne and Arapaho ban alongside existing hyperscale prohibitions from the Cherokee Nation, the Seminole Nation and the Kickapoo Tribe of Oklahoma, making Cheyenne and Arapaho the fourth tribal government in the state to adopt some form of data center restriction. Oklahoma Energy Today did not report when those three bans took effect, so it is not established how many of the four landed in the same year as this one. What is not in dispute is the deal size the tribe walked away from: no reporting identifies a named operator behind the $200 million figure, or confirms a specific site under evaluation on Cheyenne and Arapaho land.

Oklahoma City's pause set the template

The tribal vote is not the state's first data center moratorium this year. Oklahoma City's council unanimously approved a temporary halt on new data centers within city limits on April 21, running through December 31, 2026, according to a city release. City Manager Craig Freeman said the pause would let the city study effects on energy use, water demand and land use before resuming approvals. The moratorium froze rezoning requests and permit processing but exempted two cases already pending in the system.

Where Oklahoma City's pause is time-bound and tied to a planning study, the Cheyenne and Arapaho moratorium runs three years and sits on top of a sovereign land base where county zoning authority does not reach. That distinction matters for any operator evaluating sites near tribal trust land in western Oklahoma: a county approval does not substitute for tribal consent.

The state moved on cost allocation, not siting

While local governments paused approvals, the legislature moved on a narrower question: who pays for the power. Governor Kevin Stitt signed House Bill 2992, the Data Center Customer Ratepayer Protection Act, on August 6, with an effective date of July 1, 2026, according to the Oklahoma House of Representatives. The law requires large-scale energy users to cover their own infrastructure costs rather than shifting them to residential ratepayers, and it obligates developers to notify county commissioners and the Oklahoma Corporation Commission within 60 days of acquiring land for a project.

That notification requirement is the piece most relevant to planners watching the next proposal land in their county: it creates a public record trigger that did not previously exist, independent of whatever zoning process a county runs on its own schedule.

Utilities have been filing their own cost-allocation mechanisms in parallel. OG&E proposed a large-load tariff to the Oklahoma Corporation Commission on June 17, 2026, requiring any customer drawing 75 megawatts or more to pay for its own grid connections and for estimated electricity usage regardless of actual consumption, according to KOSU. The same KOSU report put a fund in the filing at $25 million to $30 million annually, to be credited back to residential and vulnerable customers — that figure is KOSU's characterization of the filing, and no Commission order confirming the fund's size appears elsewhere. The Corporation Commission opened docket PUD2026-000046 on June 25, 2026, to review the tariff, according to GovData.

PSO's capacity order is already in court

Not every large-load cost fight in Oklahoma has stayed at the settlement-filing stage. State Representative Tom Gann appealed a Corporation Commission order to the Oklahoma Supreme Court challenging $1.3 billion in new generation capacity approved for Public Service Company of Oklahoma, according to an Oklahoma House of Representatives release dated June 2, 2026. Gann's appeal argues the capacity buildout exists to serve large-load industrial customers, including multiple proposed data centers, and the release states that more than 300 PSO customers have intervened in the underlying rate case to object to the infrastructure costs.

That appeal is still pending, and it sits upstream of every siting decision in PSO's territory: a reversal would change the generation math behind any data center counting on that capacity being built on the current timeline.

What the pattern tells the next county and the next tribe

The common thread across the KOSU, KECO, El Reno Tribune and Oklahoma Energy Today accounts of the Cheyenne and Arapaho vote is water, not power. Every tribal member quoted in that reporting framed the objection around drought exposure, water rights adjudication or effects on farmland and herds, not around the electricity cost allocation driving the legislature and the Corporation Commission dockets.

A county government weighing a rezoning request runs into HB 2992's 60-day notification requirement and whatever large-load tariff OG&E or PSO has pending before the Commission. A tribal government weighing the same proposal on trust land answers to neither mechanism, and in Cheyenne and Arapaho's case reached for a three-year ban rather than a tariff filing.

The $200 million a year Wassana cited as the case for the deal is, on the record so far, the only figure anyone has put on what the moratorium cost the tribe to pass.
