Google's $17 Billion Wyoming Data Center Will Pay Its Own Way and Skip the Water Fight. The City Around It Is Still Planning Off a 2014 Map.

Larry Wolfe sits on the Cheyenne City Council, and he keeps coming back to one line: the city is still governing growth off a master plan written in 2014, one that was supposed to get refreshed every five years and never has. That's the frame he reached for again this month, as Google finally said out loud what half of Laramie County had already guessed. The $17 billion AI campus going up south of the city, long known only by a code name, belongs to Google.

The project is called Project Tembo now. For most of the past year it ran under a different one, Project Jade, and nobody outside a small circle of developers and county officials knew who was actually paying for it. Cowboy State Daily broke that mystery first, in July, reporting that Google had taken over the site through a subsidiary called Jupiter Star Holdings LLC after the original developer, Crusoe, stepped back. On November 5th, Google made it official: a 2.7-gigawatt campus on 716 acres in the Switchgrass Industrial Park south of Cheyenne, four buildings totaling more than three million square feet, and a blog post laying out, for the first time, how the company plans to pay for all of it.

Cheyenne isn't new to this. Meta and Microsoft already run data centers in and around the city, and officials have put the number of additional projects somewhere in active discussion at 40 to 70, depending on who's counting and when. Project Tembo is the biggest single piece of that pipeline by a wide margin, and the first one with Google's name attached to a dollar figure this large.

A power stack built to skip the queue

A campus this size doesn't wait in line for power, it builds its own. Tallgrass Energy is putting more than $7 billion into a dedicated gas-fired hub on the site, running Mitsubishi Power turbines. Black Hills Energy is building a separate piece — $1.8 billion for 564 megawatts of new generation between 2027 and 2029, under agreements it signed with Google in October that I've covered here before, structured so the cost lands on Google's side of the ledger rather than Wyoming ratepayers'. Layered on top of both is a planned 702-megawatt fuel-cell installation from Bloom Energy, with the carbon dioxide it produces piped to a Tallgrass sequestration site instead of the air. One industry tracker puts American Electric Power's piece at roughly $4 billion under a 20-year power purchase agreement, though that figure hasn't shown up in Google's own materials, so treat it as reported rather than confirmed. Four companies, four different financing structures, one customer behind all of them.

The reason four companies are building four separate power sources instead of one utility running a single new line back to the grid is the same reason this keeps happening everywhere a gigawatt-scale load shows up: a project this size would otherwise sit in a regional interconnection queue for years, behind every other generator and load waiting on the same studies. Pairing the campus with dedicated, on-site generation is how a developer buys back that time. It's the same math behind Oracle's fuel-cell plan in New Mexico and Aligned's gas plant in Pennsylvania, just assembled here across more partners than usual, and spread across enough of them that no single contract carries all the risk.

What Google is promising in exchange for that stack is the same thing it already promised Black Hills in writing: it will cover the full cost of the electricity the campus uses and the grid upgrades its growth requires, not just at the margin but for the life of the project. Google's own estimate puts the resulting property tax revenue at hundreds of millions of dollars for Laramie County and Laramie County School District Number 1, the state's largest school district by enrollment. That number is Google's projection, not an audited county forecast, and it assumes the carbon-capture and generation buildout actually gets delivered on schedule. It's still the right kind of number to be arguing about — a local tax base, not a developer's incentive ask.

Air instead of water

The cooling choice here is the one I'd flag first if I were advising a county on this deal. Project Tembo is designed to run on air cooling rather than the evaporative systems most hyperscale campuses still default to, which trades a meaningful efficiency cost for a much smaller water draw. That's not a free decision — air-cooled systems generally need more electricity to move the same heat than water does, which is part of why this campus needed four separate power deals instead of one. But it reads as a deliberate one, coming four months after a Meta contractor contaminated Cheyenne's recycled irrigation water with a bacterium that can make people sick, a story the city sat on for weeks before residents found out. Cheyenne's mayor called water "our biggest conversation" before that scare even happened. Google building its newest, biggest campus around a technology that mostly removes itself from that conversation is either good engineering or good politics. It's probably both, and either way it's the right call for a city that just spent a summer finding out what happens when water planning falls behind.

The part money doesn't fix

None of the financial engineering touches the thing Wolfe is actually angry about. Google says it met with more than 200 Laramie County residents at a downtown community meeting around the announcement, and it's standing up a Community Council with Tallgrass, Black Hills, and Bloom Energy to work through growth concerns as the campus gets built. That's a real mechanism, not just a press-release gesture, but it's also the fourth or fifth version of "let's talk about it" Cheyenne has tried this year. Several hundred residents have already signed a petition asking the city for a moratorium on new data center approvals. A 12-month moratorium proposal died on a lopsided council vote back in May. The arguments haven't changed much since: traffic, noise, light pollution, and a sense that the pace of approvals has outrun anyone's ability to plan for what's actually landing on the ground.

The timing wasn't an accident. Two days before Google's announcement, voters in local races across the country had just delivered what multiple outlets, citing Ballotpedia's own tracking, described as a near-sweep against data center expansion — somewhere around 40 of the 41 local measures on data center policy going the restrictive way. Google's new framing, emphasizing community meetings and cost pledges rather than just megawatts, reads like a company that watched that result land and adjusted its messaging within the week.

I think the honest read is that the hard financial problem here is basically solved. Black Hills' tariff structure, Google's cost-coverage pledge, and the sequence of signed contracts behind both are a genuinely tested answer to "who pays for the substation nobody but one customer asked for." Ratepayer protection used to be the open question in deals like this one. It increasingly isn't. What's still open is the much slower, much less glamorous question Wolfe keeps asking out loud: whether a city of under 70,000 people, working from a map that's five years past its own renewal date, can plan land use, water, and traffic fast enough to keep up with a customer that moves at Google's pace. A Community Council is a fine place to start answering that. It will only matter if it produces an actual master-plan update on a schedule that lines up with Project Tembo's own 2031 construction target, not another round of meetings that ends the way the last few have.
