What was already public
The announcement reads as a single new decision. The contracts say otherwise. On October 6, Black Hills Corp. filed definitive agreements with the SEC, effective September 30 and running through 2048, to serve a planned Google data center in Cheyenne. That filing already contained the shape of the whole power plan: a total resource mix of 2.7 gigawatts including reserve margins, made up of up to 590 megawatts of grid-connected service plus about 2.1 gigawatts of third-party contracted resources managed through a private microgrid. Black Hills plans to invest $1.8 billion between 2027 and 2029 in 564 megawatts of new gas generation of its own, expects service to begin in late 2027 and reach peak load in 2030. Black Hills projects approximately $2.4 billion in unlevered free cash flow through 2048, net of its planned $1.8 billion investment in 564 MW of its own new gas generation between 2027 and 2029. This is the company's projection, not realized cash flow.
AEP announced its part on October 14: an approximately $4 billion investment in a 702 MW fuel-cell plant near Cheyenne. According to AEP, Google will purchase the plant's output under a 20-year power purchase agreement with Cheyenne Fuel Cell, LLC, which is approximately 92% owned by AEP. AEP said construction was expected to begin in 2026, with full operation targeted by the end of 2028.
The genuinely new item on November 5 is Google's stated long-term $17 billion investment in Wyoming, accompanied by community and infrastructure commitments. The announcement does not provide a spending breakdown, construction schedule or data-center opening date. The underlying power arrangements had already been disclosed by the partners in October. That is not nothing. A public total creates a number the county can hold the company to. But readers should know the machinery was contracted a month before the headline arrived, and that neither utility has confirmed whether the 702 fuel-cell megawatts sit inside Black Hills' 2.1-gigawatt third-party bucket. Adding the figures together, as some coverage does, double-counts capacity that may only exist once.
The missing rate
The claim that needs a number does not get one. Google says the capture system will take "a large majority" of the fuel cells' carbon emissions and store them permanently underground. Google does not define what "a large majority" means numerically. It publishes no capture percentage, annual CO2 tonnage or date when capture operations are expected to begin. Without those figures, readers cannot calculate the project's expected emissions reduction or compare its performance with other carbon-capture installations. The difference, across 702 megawatts of gas generation running for two decades, is the difference between a meaningful reduction and a rounding error with good public relations.
Google is precise elsewhere in the same post: 702 megawatts, nearly 1 gigawatt of contracted capture capacity, 100% of power costs covered, more than 200 residents at a community meeting. The one figure left as an adjective is the one that decides whether the climate part of this announcement is substance or framing. AEP described the planned system in October as delivering "near-zero-emissions power." That is AEP's characterization of a facility that has not yet been built, not an independently measured emissions result. Without a disclosed capture rate or operating data, the phrase remains a project claim rather than demonstrated performance.
There is a practical test available. When the plant approaches operation at the end of 2028, the capture rate will either be published as a measured figure or it will stay an adjective. Until then, the honest summary of Wyoming is narrower than the headline: a very large, mostly contracted gas-powered build, a contracted CO2 storage destination, and a climate claim whose size nobody has yet agreed to state.
