Graded Minimal and steady. 8 laws, orders, rulings and local actions, each with its source, reviewed 27 October 2026.
Executive Order 2026-03 (June 4, 2026) streamlines permitting and only expects developers to cover their power costs; no study or tariff rule exists.
No large-load tariff or cost rule is in force; the June 4, 2026 executive order's cost expectation is not binding.
Cheyenne rejected a moratorium 8-1 in May 2026 and approved a 1,260-acre annexation September 28, 2026; the executive order streamlines rather than restricts.
No incentive item and no incentive action appears in the file, so this scores 3: nothing to lose, nothing to gain.
Executive Order 2026-03 (June 4, 2026) tells agencies to weigh water and wildlife but imposes no reporting, limit or disclosure duty on developers.
Scored on rules in force, 1 to 5. 5 is the most regulated. Pending rules set the arrow.
Governor Gordon's Executive Order 2026-03, in effect since 4 June 2026, tells agencies to coordinate and streamline permitting and to weigh water, wildlife, grid reliability and community effects, and says developers must cover the cost of their own power demand. Some legislators answered by polling colleagues on a special session to revisit statutes on large generation, water and infrastructure; none was called. The Public Service Commission in July 2026 refused to carve an Anschutz power plant out of Rocky Mountain Power's territory while it drafts non-utility generator rules, and Black Hills has a transmission cost mechanism for large contract customers pending for 1 January 2027. Cheyenne, the state's data center hub, voted 8-1 in May 2026 against a one-year moratorium, approved a roughly 3,460-acre Microsoft annexation in July and a 1,260-acre annexation for a data center business park on 28 September 2026, while a resident is challenging the Microsoft annexation in court.
The general session starting in January 2027, with a new governor after the November 2026 election, is the venue for bills on large generation, water and cost protection; the Revenue Committee already has a data center industrial property draft (27LSO-0111). At the Public Service Commission, the non-utility generator rules, Black Hills' transmission cost mechanism (requested effective 1 January 2027) and the Rocky Mountain Power and Black Hills rate cases are pending. In Cheyenne, the court challenge to the Microsoft annexation is unresolved and the council has continued to approve data center land.
No. As of 27 October 2026 no statewide or local moratorium on data centers is in force in Wyoming. Proposals and expired pauses are not counted.
Steady. Wyoming is graded Minimal, which means few binding rules, with new incentives or fast-track permitting in force. Governor's order streamlines permitting for data centers; Cheyenne keeps annexing land for them. The outlook above says what is pending.
Wyoming sits in SPP and The West outside California. The grid operator decides how a new large load is studied, what it must bring or pay, and whether it can be curtailed first; the state decides siting, permits, tariffs and incentives.
No. Wyoming's data center incentives were not pulled back in 2025 or 2026 as of 27 October 2026, though the items below show what is pending.
On Genloop's five-line rubric (1 least regulated, 5 most) Wyoming scores grid connection 1, power rates 1, siting and land use 1, tax treatment 3, permits and water 1, a mean of 1.4. The most regulated line is tax treatment: No incentive item and no incentive action appears in the file, so this scores 3: nothing to lose, nothing to gain.
8 items: each is a law, order, tariff, ruling, utility action or local decision that changes what a data center must do, pay or disclose, or where it may be built. Failed and pending measures are marked. Each links to its source.
Approved 8-2 on third and final reading on 28 September 2026, with the land rezoned from agricultural to business park. The developers are Skybox Data Centers and ViaWest Group and no end user has been named. The vote had been postponed from April after public backlash. Cheyenne has 10 operating data centers, 5 under construction and 9 in development.

No ruling has been reported.

The commission called the request premature while it drafts non-utility generator rules, with a public hearing held 5 August 2026.

Daniel Singh polled lawmakers in June 2026 on a special session covering statutes on large electrical generation, water and infrastructure. Sponsors said it was not a statewide moratorium. No session was called; the Legislature next meets in January 2027.

The utility is negotiating definitive agreements for a 1.8 GW Cheyenne data center under that tariff and holds $377 million in refundable customer advances for generation equipment.
