Oracle is backing Frontier, a planned 1.4-gigawatt AI data-center campus in Shackelford County, Texas. Vantage Data Centers is developing the more-than-$25 billion campus, while Oracle is the associated cloud customer and infrastructure operator. Construction is underway, but the original description of a gas-turbine- and diesel-powered facility is no longer complete: Oracle said on June 16, 2026, that Bloom Energy fuel cells would replace those initially proposed systems. Oracle’s current tracker lists customer delivery beginning in the first half of 2027, with 115 megawatts already available.

Vantage announced Frontier on August 19, 2025, describing it as its largest campus and a more-than-$25-billion development. The announcement originally targeted delivery of the first building in the second half of 2026. Oracle’s later schedule is the more current public expectation. See Vantage’s announcement and Oracle’s data-center tracker.
What Oracle and Vantage are building
Frontier is intended for high-density GPU computing and Oracle Cloud Infrastructure workloads, including artificial-intelligence training and inference. Vantage’s campus materials describe 1.4 GW as critical IT load—the power allocated to computing equipment—not a guarantee that the entire campus is already consuming 1.4 GW or that total facility demand will equal that number.
The planned build-out covers 10 buildings on 1,200 acres, with about 3.7 million square feet of data-center space. Vantage says the design supports racks of at least 250 kilowatts, liquid cooling, closed-loop cooling systems, multiple power feeds and N+1 mechanical redundancy. Its technical sheet lists average densities of up to 1.4 kilowatts per square foot. These are design specifications for the completed campus; capacity will ramp as buildings, electrical systems and computing equipment enter service. Technical details are in Vantage’s campus page and its Frontier data sheet.

Why a private power system matters for AI
AI campuses impose large, steady loads that can exceed the capacity available at an existing utility connection. Transmission upgrades, substations and interconnection studies can take longer than constructing data halls. An on-site generation system or microgrid can therefore provide firm power while utility work proceeds and can give the operator more control over timing and reliability.
The trade-off is that the project must manage generation equipment, fuel contracts, maintenance, emissions permits, emergency backup and the economics of operating a private power system. An on-site system does not prove that the campus is permanently off-grid: Oracle has not disclosed that Frontier will operate independently of utility service in every circumstance.
Is Frontier still a “gas-powered” data center?
That wording describes the initial proposal, not Oracle’s latest public plan. Early project descriptions referred to gas turbines and diesel generators. In a June 16, 2026 statement, Oracle said Bloom Energy fuel cells would replace those systems for the relevant AI campus. Read Oracle’s update at “Setting the record straight on fuel cells and toxic chemicals.”
How the technologies differ
| Technology | How it produces power | What is established for Frontier |
|---|---|---|
| Gas turbine | Burns fuel to produce mechanical power that drives a generator | Initially proposed; Oracle says it will be replaced |
| Diesel generator | Combustion engine used commonly for backup power | Initially proposed; Oracle says it will be replaced |
| Bloom Energy fuel cell | Generates electricity electrochemically from a fuel input | Oracle’s current stated replacement plan |
Fuel cells may use pipeline natural gas, so the revised plan is not automatically renewable or zero-carbon. It is also not equivalent to conventional gas-turbine generation. Oracle says the change should lower local emissions compared with combustion generation and reduce ongoing water use; those are company claims, not independently verified operating results. Oracle has not publicly provided, in the cited materials, the final fuel-cell output by building, gas consumption, emissions profile, permit limits or the exact role of utility and backup power.
Schedule: from announcement to delivery
- August 19, 2025: Vantage announced Frontier as a more-than-$25-billion, 1.4-GW campus.
- August 2025: Oracle’s tracker records the Shackelford project as contracted.
- 2025: Construction was announced as underway.
- January 2026: Oracle said its U.S. AI-infrastructure projects, including Shackelford County, were being built with partners.
- June 2026: Oracle announced the shift from the initially proposed turbines and diesel generators to Bloom Energy fuel cells.
- Current 2026 tracker: Oracle reports 115 MW available and customer delivery beginning in the first half of 2027.
The precise date for completing the full 1.4-GW build-out has not been established in the public material cited here. The original second-half-2026 target should therefore be treated as superseded by the later first-half-2027 customer-delivery listing.
Cooling, water and environmental questions
Oracle says Frontier will use a one-time-fill, closed-loop, non-evaporative liquid-cooling system designed to avoid drawing on the community’s public drinking-water supply. Vantage separately describes closed-loop chiller systems intended to minimize water use. These statements concern the disclosed cooling design, not proof that the entire campus or its power equipment will consume no water. Oracle’s project description is at the Shackelford County project page.
Questions that remain open
- How much water is needed for the initial fill and for any lifetime makeup?
- Does the water statement cover only server cooling or also buildings, fuel-cell equipment and emergency systems?
- What happens to water demand during drought conditions or maintenance?
- What are the fuel-cell emissions of nitrogen oxides, carbon dioxide and other pollutants at the planned output?
- Which air permits, emissions limits, noise controls and backup-generation arrangements apply?
- Will all primary power come from fuel cells, or will they supply only part of the campus load?
Even if the campus reduces immediate utility demand, it can still affect regional infrastructure through gas-pipeline demand, substations, transmission planning and supplemental utility service.

Oracle projects more than 5,000 construction jobs, more than 1,600 ongoing project-supported jobs and more than $100 million in local county tax revenue. It also says the project will provide annual scholarships for Shackelford County students and give preference to local suppliers, contractors, vendors and residents. These are company projections and commitments, not independently audited outcomes. “Ongoing project-supported jobs” may include indirect and supplier-supported employment rather than only permanent jobs inside the data halls.

Who is paying for the project?
Vantage announced an investment of more than $25 billion to develop Frontier. That figure does not establish that Oracle alone is spending $25 billion. The reviewed public materials do not disclose how capital costs are divided among Oracle, Vantage, power suppliers, contractors, lenders or other partners. The careful description is therefore Vantage’s more-than-$25-billion campus development associated with Oracle, not “Oracle’s $25 billion project.”
Oracle’s wider AI build-out
Oracle’s January 2026 update places Shackelford County among a broader U.S. AI-infrastructure program being built with partners in Texas, New Mexico, Wisconsin and Michigan. That context explains the urgency around power and construction, but it does not establish that every site uses the same generation technology, ownership model or delivery schedule. Oracle’s broader statement is available at its January 2026 infrastructure update.
What to watch next
- Whether customer delivery begins on the first-half-2027 schedule.
- How quickly available capacity rises above the reported 115 MW.
- Fuel-cell installation dates, rated output and fuel arrangements.
- Air permits, emissions limits and environmental reporting.
- Utility interconnection, pipeline and substation plans.
- Any revised timetable for reaching the full 1.4-GW critical IT capacity.
Bottom line
Frontier is a real, under-construction AI campus planned at a scale of 1.4 GW, but its most important current power fact is the change in design. Gas turbines and diesel generators were part of the original proposal; Oracle now says Bloom Energy fuel cells will replace them. Calling the project simply “gas-powered” misses that update, while calling it renewable or zero-emission would go beyond what Oracle has disclosed.
