Data Center Land in Montana (MT)
Montana has gone from essentially no data center footprint to a state with named development agreements, a proposed large-load tariff, and a multi-hundred-megawatt project pipeline in the space of about a year. NorthWestern Energy's agreements with Sabey Data Centers and Atlas Power Holdings anchor the activity, but the power behind those projects is coming from a coal plant, not wind or solar — a detail worth knowing before assuming Montana fits a clean-energy sourcing strategy.
⚡ TL;DR — Montana Data Center Overview
- • Market stage: early but concrete — NorthWestern Energy development agreements with Sabey Data Centers and Atlas Power Holdings, combined ~150 MW starting late 2027, scaling toward ~1,500 MW by 2030
- • Utility: NorthWestern Energy serves most of the state; some rural areas served by member-owned electric cooperatives instead
- • Power source: the Sabey and Atlas projects will initially draw from the Colstrip coal-fired plant starting 2026 — not a renewable source
- • Regulatory: NorthWestern filed a Large New Load Tariff application with the Montana PSC (March 31, 2026) to allocate large-load grid costs; a 2026 Integrated Resource Plan is shaping the broader framework
- • Risk factor: active ratepayer and legislative attention on who pays for new large-load grid capacity
Active Montana Activity
- Sabey Data Centers — NorthWestern development agreement
- Atlas Power Holdings — 75 MW from 2026, +75 MW in 3-5 years
- Quantica Infrastructure — transmission/generation study agreement (April 2026)
Regulatory Levers in Play
- Large New Load Tariff application filed with Montana PSC, March 2026
- NorthWestern's 2026 Integrated Resource Plan shaping large-load framework
- No broad data-center-specific state tax exemption yet — confirm current status

Grid & Utilities in Montana
NorthWestern Energy is the dominant utility across most of Montana and the counterparty on every large-load development agreement signed so far. Rather than running an open interconnection queue that any landowner can watch, NorthWestern has been negotiating specific development agreements project by project — with Sabey, Atlas Power, and Quantica Infrastructure all named counterparties as of mid-2026. That's a different dynamic from a mature PJM or ERCOT market, where large-load requests flow through a more standardized process. See our interconnection queue guide for how the underlying study process generally works, and confirm current NorthWestern large-load terms directly rather than assuming a generic timeline. Parts of rural Montana are served by member-owned electric cooperatives rather than NorthWestern, which changes who you'd actually be negotiating with for a given parcel.
Key Development Considerations
- The power supplying the first wave of Montana projects (Sabey, Atlas) comes from the Colstrip coal plant starting in 2026 — a real consideration for any buyer with a clean-energy sourcing requirement, and a genuine differentiator from wind- or hydro-heavy neighboring states
- NorthWestern's pending Large New Load Tariff (filed March 2026) could materially change large-load cost structure once approved — confirm current status before modeling a deal
- Montana's near-term large-load capacity has moved through negotiated development agreements with a small number of named developers, not an open queue — a new entrant's timeline may look different from what's been reported for Sabey or Atlas
- Land itself is abundant and inexpensive across most of the state; the binding constraint is proximity to NorthWestern's existing transmission backbone, particularly infrastructure tied to Colstrip and the state's limited number of high-voltage corridors
Land Values in Montana
Montana has essentially no established data center land comps yet — the market is too new, and the handful of confirmed deals have been negotiated directly with NorthWestern rather than playing out as visible land transactions. That makes a local commercial or agricultural broker comp, or a direct site submission, far more useful than any statewide estimate. Much of the land likely to draw developer interest is currently agricultural or ranchland; landowners in that position should also review our guide to selling farmland to data center developers for issues — rollback property taxes, water rights, existing crop or grazing leases — that a generic land-sale guide won't cover. See also how much power a data center needs by facility size and why land near substations matters to value.

What's Different About Evaluating Land in Montana
Montana's land base is dominated by cattle ranching and dryland farming, with genuinely large single-owner tracts more common than in almost any other state on this site — a real advantage for a campus that needs hundreds of contiguous acres without an assemblage process. It also has one land-use quirk worth knowing: many Montana counties have no comprehensive zoning ordinance at all, which can either simplify a data center proposal (no formal rezoning fight) or complicate it (fewer established permitting pathways and precedents for local officials to follow), depending on the county and how organized local opposition, if any, turns out to be. That's a meaningfully different starting point than a state with mature industrial zoning frameworks already built around large-load development.
Distance is also a practical factor in a state this size. A parcel with strong power fundamentals near Colstrip or an existing NorthWestern transmission corridor may still be hours from the nearest major population center, which affects construction labor logistics and, longer term, the operational workforce a facility needs — worth flagging honestly rather than assuming Montana's low land costs come with no offsetting tradeoffs.
Frequently Asked Questions
Is Montana a real market for data center development, or just talk?
It's real, though still early. NorthWestern Energy — the utility serving most of the state — has signed development agreements with Sabey Data Centers and Atlas Power Holdings LLC, with a combined energy service requirement currently projected at 150 megawatts beginning in late 2027, growing to roughly 1,500 megawatts or more by 2030 if all the associated projects move forward. Atlas alone is contracted for 75 MW starting in 2026, with a further 75 MW expected within three to five years. NorthWestern also signed a development agreement with Quantica Infrastructure in April 2026 to evaluate the transmission and generation resources a further project would need. That's meaningfully more concrete activity than most states that get labeled 'emerging' — but Montana has nothing like Virginia or Ohio's decade-plus operating track record yet.
What utility serves Montana data center sites, and where does the power come from?
NorthWestern Energy serves most of Montana and is the counterparty on the development agreements signed to date. Notably, the power supplying the Sabey and Atlas projects is set to come from the Colstrip coal-fired power plant in southeastern Montana starting in 2026 — worth flagging plainly, since it cuts against the renewable-power narrative that dominates data center siting coverage elsewhere and matters directly to buyers with clean-energy sourcing commitments. Some parts of the state are served by rural electric cooperatives rather than NorthWestern directly, so confirm the specific utility territory for any parcel before assuming standard NorthWestern terms apply.
Is there political or ratepayer pushback against data centers in Montana?
Yes, and it's active. NorthWestern filed an application with the Montana Public Service Commission on March 31, 2026 requesting approval of a Large New Load Tariff, designed to ensure data centers and other large new-load customers pay their own way rather than shifting grid costs onto existing residential and commercial ratepayers. That filing, along with NorthWestern's 2026 Integrated Resource Plan, is effectively an attempt to establish a formal cost-allocation and permitting framework for large loads before the bulk of the announced capacity actually comes online — and it's drawn public attention from ratepayer advocates who want a say in how those rates get structured. Expect utility cost-allocation questions to come up in diligence on any Montana site, not just the interconnection study itself.
Does Montana have land and power availability for a large-scale project?
Land availability isn't the constraint — Montana is vast and sparsely populated, with large tracts of rural and agricultural land throughout the state. The real constraint, as everywhere, is deliverable power: NorthWestern's near-term large-load capacity is being allocated through specific, negotiated development agreements rather than an open queue, and the state doesn't yet have the dense transmission buildout that established markets like PJM territory have. A parcel's realistic prospects depend heavily on proximity to NorthWestern's existing transmission backbone — including infrastructure tied to Colstrip — rather than raw acreage alone.
Can I submit land in Montana for data center consideration?
Yes. If you own or represent land in Montana near NorthWestern Energy transmission infrastructure, existing industrial or power-generation sites, or rural electric cooperative territory with known capacity, submit it via our site intake form for a confidential review. Montana's market is early enough that even preliminary interest is worth documenting now, before more developers move in and establish shortlists.
