NorthWestern Energy Group Partners with Atlas Power for Montana Data Center Electric Service

NorthWestern Energy Expands Electric Service to Support Data Center Growth in Montana

NorthWestern Energy Group, Inc. has announced a significant development in its energy supply strategy by partnering with Atlas Power Group to provide electric service for a new data center in Butte, Montana, set to commence in 2026. This agreement marks a pivotal step in NorthWestern's efforts to enhance its service capabilities to large-scale customers, as the initial electricity supply is projected at 75 megawatts, with the potential to double that capacity within three to five years. This strategic move aligns with NorthWestern’s goals of maintaining a balanced energy portfolio while ensuring reliability and affordability for its existing customer base.

The partnership exemplifies NorthWestern Energy's commitment to meeting the demands of modern energy consumers, especially in the rapidly growing data center sector. Brian Bird, the company's President and CEO, underscores the importance of strategic acquisitions that bolster the firm’s ability to cater to large customers like Atlas Power Group. The cooperative relationship not only supports Atlas's operational needs but also reflects NorthWestern’s overarching vision of fostering growth in Montana's technology infrastructure. By securing long-term, cost-effective energy solutions, NorthWestern positions itself as a key player in the region's economic development.

In addition to the Atlas Power Group agreement, NorthWestern Energy has recently finalized contracts with other developers looking to establish data centers in Montana. This series of agreements highlights the company’s proactive approach in addressing the increasing energy demands from the tech industry. NorthWestern Energy is recognized as one of the nation's cleanest energy providers, sourcing a substantial portion of its energy from renewable resources such as hydro, wind, and solar power. The upcoming introduction of on-demand energy from the Yellowstone County Generating Station, along with anticipated contributions from the Colstrip Plant in early 2026, will further solidify NorthWestern’s capability to deliver reliable and competitively priced energy services.

NorthWestern Energy currently serves approximately 775,300 customers across Montana, South Dakota, Nebraska, and Yellowstone National Park, demonstrating its vast reach and commitment to safe and innovative energy solutions. As the company continues to expand its service offerings and infrastructure, the collaboration with Atlas Power Group signals a promising future for energy development in Montana, paving the way for enhanced grid reliability and economic growth.
