Black Hills has agreed to invest $1.8 billion to supply power to Google's data center in Cheyenne, Wyoming. The commitment, announced this week, is one of the largest utility investments tied to a single tech facility and underscores how much electricity the AI boom is demanding.
The deal gives Google a dedicated power source for a campus that has been expanding for years. It also puts Black Hills on the hook for new generation and transmission capacity, costs that will ultimately show up on ratepayer bills unless regulators intervene.
Why Google needs a dedicated power deal
Data centers are not like other commercial customers. They run around the clock, draw hundreds of megawatts at peak, and need power that won't flicker. As Google scales up AI workloads in Cheyenne, the local grid can't absorb the load without upgrades. Black Hills is promising to build those upgrades—new lines, substations, and likely additional generation—at a cost of $1.8 billion.
The arrangement shifts some of the risk of serving a mega-load off the utility's general rate base and onto a contract with a single, creditworthy customer. That's the theory, anyway. The details of who pays for what haven't been fully disclosed.
What Black Hills gets out of it
For Black Hills, the deal locks in a long-term revenue stream from a Fortune 500 tenant. It also gives the utility a rationale to invest in infrastructure that might otherwise be hard to justify in a state with a small population and modest load growth. Wyoming regulators will still need to sign off on the cost recovery mechanism, and consumer advocates are likely to scrutinize any language that lets the utility pass costs to residential customers if Google's demand forecasts miss.
The $1.8 billion figure is a commitment, not a completed spend. It will be drawn down over years as the data center expands. Black Hills hasn't said exactly how many megawatts the deal covers or when the first new power will flow.
A template for other utilities
Utilities across the country are watching. Tech companies are signing similar arrangements in Virginia, Oregon, and Texas, but few involve a single utility putting up this much capital for one customer. If the Cheyenne model works—if Black Hills earns a return without sticking ratepayers with stranded costs—it could become the default approach for serving AI data centers in rural areas.
If it doesn't, the precedent could chill other deals. The risk is asymmetric: Google can walk away from a site if power gets too expensive, but Black Hills can't walk away from the transmission lines it builds.
What to watch next
The Wyoming Public Service Commission will review the cost recovery plan in the coming months. Black Hills has not filed a formal tariff application yet, and the timeline for construction depends on permitting and supply chain availability for transformers and other equipment, which remain backlogged across the industry.
Google, for its part, has not said whether the Cheyenne campus will host AI training, inference, or general cloud services. That distinction matters for load shape. Training clusters can be curtailed; inference for live products cannot. The utility will need to know which one it's building for.
