Alaska Data Center Proposals Face Scrutiny

The main update is a sharper characterization of the North Slope proposal: it is now described as a gigawatt-scale project, and the current version adds more explicit commercial and technical uncertainties around whether it can actually secure customers, financing, and infrastructure. The Houston proposal is also framed more clearly as a land-transfer request for a broader industrial district rather than a more general development concept.

The story now adds concrete procedural updates and sharper specifics: Stak’s North Slope review drew overwhelming opposition and was extended, while the Mat-Su land-transfer proposal remains open with no decision locked in. The current version also tightens the framing around costs and environmental claims, underscoring how uncertain both projects remain.

• North Slope lease review drew more than 500 comments.
• Preliminary Stak deadline was extended to July 17.
• Stak claims Arctic temperatures could sharply reduce cooling-water needs.
• Reported Stak costs range from $500 million to over $10 billion.
• Mat-Su comments are accepted through August 19.

The story has broadened from a single North Slope data center proposal into a wider Alaska siting fight involving multiple large projects, new land-transfer mechanisms, and more active local resistance. The main change is that approvals now hinge on parallel state and municipal reviews rather than just Stak Energy's leasing path.

• A Mat-Su industrial district could host scalable data centers.
• A no-cost or noncompetitive land transfer near Houston is under consideration.
• Alaska Industrial Development and Export Authority is involved in the Mat-Su proposal.
• Houston officials are considering data center restrictions.
• Public comment opposition to the North Slope project is unusually heavy.

Stak Energy is proposing a very large data center on Alaska's North Slope, with plans for a facility that could reach 3 gigawatts and occupy about one square mile near the Dalton Highway. The project is built around on-site natural gas generation, cold-climate air cooling, and a claimed sharp reduction in water use, but it still depends on land leasing, additional permits, gas supply, and turbine procurement. The proposal matters because it would be one of the largest data center builds in the U.S. and tests whether a remote Alaska site can support large-scale compute without tying into the state grid.
