TL;DR

  • Quantica Infrastructure filed interconnection applications with NorthWestern Energy tied to future power generation capacity for its Big Sky Digital Infrastructure Campus in Montana.
  • The filing begins a formal review process that takes place years before construction and is intended to support potential long-term customer demand.
  • The proposal includes renewable generation, firming generation, and battery storage.
  • Quantica says it would fund the additional power infrastructure rather than passing costs to local ratepayers.

Quantica Infrastructure has taken another step in the development of its Big Sky Digital Infrastructure Campus in Montana by filing interconnection applications with NorthWestern Energy tied to future power generation capacity for the project.

The filing supports Quantica’s 1,100 MW Big Sky Campus in Yellowstone County and is intended to help meet potential long-term customer demand while supporting regional grid reliability. According to the company, additional capacity would be delivered in multiple phases over several years and would remain aligned with customer commitments and regulatory approvals.

The filing also marks the beginning of NorthWestern Energy’s formal interconnection review process, which occurs years in advance of construction for projects of this scale.

As proposed, the applications cover a mix of renewable generation, firming generation, and battery storage representing up to 7,235 MW of maximum additional capacity. Quantica noted that renewable generation output would be materially lower than maximum nameplate capacity and that generation proposals of this scale undergo extensive review processes intended to maintain system reliability.

A central component of the announcement is Quantica’s position that the company would be responsible for the cost and construction of the proposed additional generation infrastructure.

“Quantica will pay for the additional power capacity for the Big Sky Digital Infrastructure Campus in Montana. NorthWestern Energy’s ratepayers will not be responsible for the cost of the power. As a Billings resident, I appreciate this approach and it’s important to me that my neighbors don’t foot the bill for our project,” says Charlie Baker, Chief Accounting Officer of Quantica Infrastructure.

“Developed by Montanans and grounded in local priorities, this project is designed to advance statewide economic opportunity while responsibly safeguarding communities and minimizing negative impacts to Montana’s citizens.”

Quantica also stated that Big Sky Digital Infrastructure has engaged in preliminary discussions with the Montana Department of Environmental Quality regarding permitting requirements for the campus and associated generation infrastructure, including firming power options such as natural gas, geothermal, and other potential sources.

The company framed the filing as part of broader planning for long-term infrastructure needs.

“Data center companies are looking for places that can deliver power, connectivity, and building capacity at scale. By investing in additional capacity now, we plan to address what we’re seeing in terms of power demand from data center companies. This expansion significantly increases our total investment in Montana, and the additional power capacity would result in even more economic opportunity, construction jobs over several years, and strengthen the State’s power grid,” says John Chesser, CEO of Quantica Infrastructure.

The Big Sky Campus spans 5,100 acres approximately 30 miles north of Billings and is positioned adjacent to major infrastructure including a substation, highways, and rail access. Quantica says the site is designed to support multiple data center buildings and accommodate the proposed increase in power capacity without expanding the campus footprint.

The company expects the first building to become operational in 2029. Quantica also plans to connect the campus through hundreds of miles of new fiber-ready underground conduit intended to link the site with additional U.S. markets and support regional connectivity.
