Black Hills signs $1.8 billion power supply deal with Google, lifting NorthWestern Energy stock

Black Hills Corp. announced a long‑term agreement with Alphabet’s Google to provide electricity for a new data center in Cheyenne, Wyoming. The contract involves a $1.8 billion investment, up to 2.7 GW of power and runs through 2048. The announcement caused NorthWestern Energy Group’s shares to jump sharply, while the merger of the two utilities is still pending regulatory approval and is expected to close by year‑end.

The deal adds a high‑margin, AI‑related revenue stream to the combined utility, which could enhance future earnings and cash flow. Barclays kept an Overweight rating on NorthWestern Energy but trimmed its price target to $70, reflecting the new catalyst while acknowledging remaining merger risk.
