NorthWestern Energy Group’s stock soared over 7% after its merger partner, Black Hills, secured a substantial long-term power supply deal with Google. The agreement will provide 2.7 gigawatts of power to a new Google data center in Cheyenne, Wyoming, extending through 2048.
Black Hills plans to invest $1.8 billion in new generation assets, projecting an additional $150 million in net income by 2030 and $2.4 billion in unlevered free cash flow, significantly enhancing the value of the combined entity as their merger approaches completion by year-end.

In the high-stakes world of corporate partnerships, the right alliance can redefine fortunes. This was clearly the sentiment at NorthWestern Energy Group (NWE), whose stock surged over 7% on Wednesday, fueled by exciting news from its future merger partner. The ripple effect from a major strategic announcement by Black Hills (BKH), with whom NorthWestern is set to merge, sent NorthWestern's shares soaring.
A Game-Changing Power Agreement
The catalyst behind Black Hills'—and by extension, NorthWestern's—sudden boost was a monumental power supply deal with tech giant, Alphabet's (GOOG, GOOGL) Google. Announced just after market close on Tuesday, Black Hills confirmed a series of agreements to supply electricity to a colossal new Google data center planned for Cheyenne, Wyoming.

This landmark agreement is set to span an impressive 22 years, securing 2.7 gigawatts of power for Google's facility through 2048. Black Hills will supply up to 590 megawatts using its own generation assets and market energy, with the remaining power to be sourced from third-party contracted resources within Wyoming.
To meet this substantial demand, Black Hills plans a significant capital investment of $1.8 billion between 2026 and 2029 to construct new assets capable of generating 564 megawatts of power. This strategic move is expected to yield substantial financial returns, with the Alphabet/Google deal projected to add $150 million to Black Hills' net income by 2030 and generate roughly $2.4 billion in unlevered free cash flow (FCF), even after accounting for the $1.8 billion investment.
The timing of this news couldn't be better for NorthWestern Energy Group. In August, both companies' boards of directors gave the green light to a definitive merger agreement, a deal already approved by shareholders and anticipated to conclude by the close of this year. Therefore, Black Hills' triumph is a direct boon for the soon-to-be combined entity, driving optimism among investors.
Fueling the Future: Powering AI Data Centers
The race to construct artificial intelligence (AI) data centers has created an unprecedented demand for power, establishing a critical bottleneck for tech giants. Companies like Alphabet/Google are actively seeking long-term, reliable energy partnerships, making deals like Black Hills' an increasingly valuable commodity. This agreement represents a significant victory for Black Hills and, given the advanced stage of their merger, for NorthWestern Energy Group. As the combined company moves forward, investors will be closely watching the execution of these critical generation investments.
