Google’s planned $17 billion Wyoming data-center investment names Tallgrass Energy as a power supplier, identifies Tallgrass’s sequestration hub as the proposed CO2-storage destination and includes a separate CCS engineering study.

Allstream Insiders Summary
Google has announced its first Wyoming data center as part of a long-term $17 billion investment in the state, with Tallgrass Energy positioned across the project’s planned power and carbon-management approach. According to Google’s November 5 announcement, Tallgrass is a project partner, operates gas generators from which the data center would source power and has its nearby Eastern Wyoming Sequestration Hub identified for permanent geologic storage of captured carbon dioxide.
The announcement also says Google is conducting a technical front-end engineering and design, or FEED, study to evaluate fitting Tallgrass combined-cycle turbines with carbon capture and storage, or CCS. That study is an engineering evaluation—not a disclosed final investment decision, construction authorization or equipment award for a Tallgrass turbine retrofit.
Google said the project is contracted with American Electric Power, or AEP, to feature a planned 702-megawatt fuel-cell development with CCS, using fuel cells made by Bloom Energy. The company said the captured emissions would be permanently stored at Tallgrass’s Eastern Wyoming Sequestration Hub. Google did not disclose a project schedule, capital allocation among the data center, generation and CCS elements, equipment quantities, or engineering and construction contractors.
How Tallgrass fits into Google’s Wyoming power plan
| Project element | Company-reported detail |
|---|---|
| Google’s announced state investment | $17 billion long-term investment in Wyoming |
| Tallgrass role | Project partner; operator of gas generators supplying part of the planned power mix; operator associated with the named CO2-storage hub |
| Fuel-cell development | Planned 702 MW development with CCS; Google says it is contracted with AEP and fuel cells will be made by Bloom Energy |
| CO2 storage destination | Tallgrass’s nearby Eastern Wyoming Sequestration Hub |
| Tallgrass turbine study | Technical FEED study evaluating CCS on Tallgrass combined-cycle turbines |
| Data-center cooling | Google says the facility will be air-cooled to reduce local water demand |
| Schedule, site-level budgets and contractor awards | Not disclosed in Google’s announcement |
Tallgrass has a role in both power supply and carbon storage
Google’s announcement gives Tallgrass two distinct roles in the planned approach: providing part of the campus’s power supply through gas generators and serving as the named destination for stored carbon dioxide. Google said it will source power from gas generators operated by Tallgrass and Black Hills Energy, while the planned fuel-cell project would capture a large majority of its carbon emissions for permanent geologic storage at the Eastern Wyoming Sequestration Hub.
That linkage makes the storage hub relevant to the project’s disclosed power configuration, not simply a separate regional CCS asset. However, Google did not provide a capture rate, annual CO2 volume, sequestration-well count, pipeline route, compression configuration, storage-injection schedule or commercial agreements for the hub.
The 702-MW fuel-cell development is separate from the Tallgrass turbine study
Google said the project is contracted with AEP to feature a commercial-scale 702-MW fuel-cell development with CCS, with Bloom Energy manufacturing the fuel cells. The announcement describes the fuel-cell development as a planned project and says it would use natural gas to generate electricity through an electrochemical process.
Separately, Google said it is undertaking a technical FEED study to evaluate adding CCS to Tallgrass combined-cycle turbines. The two disclosures should not be conflated: the fuel-cell development is an identified planned power component, while the Tallgrass combined-cycle CCS scope remains in the engineering-evaluation stage.
The release does not name the turbine model, generation capacity, FEED contractor, capture-technology provider, capital cost or target in-service date for a possible Tallgrass turbine retrofit.
Google frames the investment as a data-center and infrastructure commitment
Google describes the Wyoming development as its first data center in the state and says its $17 billion commitment is long term. The company said it intends to pay for 100% of the power it uses and cover infrastructure needs directly driven by its growth. It also said the data center will be air-cooled to minimize the strain on local water resources.
The $17 billion figure applies to Google’s stated Wyoming investment as a whole. It should not be treated as a disclosed construction budget for Tallgrass’s generators, the 702-MW fuel-cell development, the sequestration hub, a potential CCS retrofit or any one supplier package.
What could be involved if the power and CCS scopes move into execution?
Allstream perspective: Depending on final engineering, permits and commercial agreements, a project that combines natural-gas generation, fuel cells and CCS could involve front-end engineering and detailed design, gas-supply and interconnection work, electrical substations and transmission facilities, fuel-cell balance-of-plant systems, CO2 dehydration and compression, pipelines, injection wells, measurement and control systems, civil work, fabrication, insulation, coatings, testing and commissioning.
Those are potential work categories rather than announced Tallgrass or Google awards. The companies have not identified an EPC contractor, CO2-pipeline contractor, compressor supplier, turbine-retrofit vendor, drilling contractor, electrical contractor or construction schedule for the scopes referenced in the announcement.
Allstream perspective: Tallgrass is the infrastructure bridge between data-center load, gas power and CCS
The announcement places Tallgrass at a particularly consequential junction in Google’s Wyoming plan: supplying part of the proposed power mix while providing the named storage solution for captured CO2. The additional FEED study signals an effort to assess whether that role could extend to CCS on existing or planned combined-cycle generation, but it does not establish that a retrofit has been sanctioned.
For energy-infrastructure participants, the next decision-useful disclosures would be a final investment decision, generation and storage specifications, capture and injection volumes, permits, pipeline or well plans, project budgets, equipment orders, engineering awards and construction milestones. Until then, the development should be tracked as a major announced data-center investment with disclosed power-and-CCS partners, rather than a fully awarded construction program.
