Montana-Dakota Utilities Announces Electric Service Agreement with Applied Digital for Proposed AI Factory
MDU Resources Group’s subsidiary Montana-Dakota Utilities signed an electric service agreement with Applied Digital to supply power to Polaris Forge 3 near Center, N.D. At full capacity the campus would need 430 MW. Applied Digital expects initial operations in August 2027 and would pay for energy procurement. The North Dakota PSC must approve the ESA and filings.
How this was made

The 30-second read
Why it matters
The article discloses a new electric service agreement framework for a large AI campus (430MW at full capacity) and a start date expectation (August 2027), but provides no financial terms and notes North Dakota PSC approval is required.
Market read
Traders can update positioning around AI infrastructure expansion and power-supply contracting, but should discount immediate earnings impact due to missing economics and regulatory approval dependency.
What to watch
Regulatory approval timing, power-market pricing pass-through mechanics, and execution risk for the Polaris Forge 3 buildout could dominate realized economics versus the headline capacity figure.
Background
MDU’s Montana-Dakota Utilities already serves Applied Digital at Polaris Forge 1; this ESA extends the relationship to Polaris Forge 3 near Center, North Dakota.
Ticker impact
MDU’s Montana-Dakota Utilities subsidiary signed an electric service agreement to supply power for Applied Digital’s Polaris Forge 3 AI campus.
Moderate positive bias for MDU on deal visibility, but likely limited near-term earnings impact until regulatory approval and project ramp.
The agreement is a concrete new customer/power-supply arrangement, but the article provides no financial terms and requires regulatory filings/approval, reducing immediacy.
Applied Digital entered an electric service agreement for Polaris Forge 3, with initial operations anticipated to start in August 2027.
Positive medium-term read-through for APLD’s North Dakota expansion narrative; near-term stock reaction likely muted without economics and with regulatory dependency for the utility side.
The timeline (initial operations Aug 2027) and scale (430MW at full capacity) are supportive, but the ESA’s commercial details and regulatory outcome are not quantified here.
Market effects
Reinforces the ongoing buildout of AI data-center campuses and the centrality of power procurement/utility partnerships in scaling capacity.
Highlights North Dakota’s attractiveness for large energy users and potential grid/load planning implications around Oliver County.
Supports the broader AI infrastructure theme where power availability and long-term utility arrangements are key constraints.
Counterpoint
Without disclosed pricing/terms and with PSC approval pending, the ESA may not translate into near-term earnings or cash-flow visibility for either stock.
