NextEra and Brookfield Plan $100 Billion Paducah AI Data Center Campus

NextEra Energy and Brookfield announced on July 29 that they plan to develop a $100 billion AI data center and energy campus at the U.S. Department of Energy’s Paducah site in western Kentucky, pairing large-scale computing infrastructure with dedicated generation and battery storage.

The proposed Paducah AI data center campus would support more than 1.2 gigawatts of computing capacity and be backed by up to 2 GW of natural-gas generation and 2.6 GW of battery storage. Operations are targeted to begin in 2028, with full development planned for 2032, although the project remains subject to final negotiations and definitive agreements.

Reuters reported that Brookfield would own and operate the data center campus while NextEra would develop the associated power and storage assets. The broader project group also includes Big Rivers Electric Corporation, Jackson Purchase Energy Cooperative and Paducah Power System.

The project would combine computing with 4.6 GW of energy assets

The planned energy portfolio totals up to 4.6 GW when the proposed natural-gas generation and battery-storage power ratings are combined. That total is larger than the campus’s anticipated computing load, reflecting a design that could support the data center while also interacting with the surrounding electricity system.

Current project descriptions indicate that the campus would have approximately 1.8 GW of utility capacity and more than 1.2 GW of computing capacity. Reuters reported that as much as 1.8 GW of electricity could potentially be supplied to the grid, although the precise operating relationship among the data center, generation assets, storage system and regional grid has not yet been publicly detailed.

The Wall Street Journal reported that the dedicated energy resources would be financed and constructed specifically for the project. Big Rivers Electric would provide wholesale electric service, while Jackson Purchase Energy Cooperative would provide retail service.

Why the Paducah site was selected

The campus would occupy federal land associated with the former Paducah Gaseous Diffusion Plant, which enriched uranium from 1952 until operations ended in 2013.

The Department of Energy describes the property as a 3,556-acre government-owned site west of Paducah. Its history as a large industrial energy facility means the location already has access to transmission infrastructure, water, fiber and other services that could shorten development timelines compared with an undeveloped site.

DOE began seeking companies to build AI data centers and associated energy projects at Paducah in November 2025. Its official request for proposals required applicants to finance, construct, operate and eventually decommission their projects while also securing the necessary utility-interconnection agreements.

Brookfield and NextEra were subsequently selected to negotiate leases and development arrangements for the campus and its energy infrastructure. The project is not yet equivalent to a completed lease, approved construction plan or operational power facility.

The 2.6 GW battery figure leaves an important question unanswered

The proposed 2.6 GW battery system would be one of the most consequential elements of the project for grid operators and distributed-energy planners. Battery power capacity indicates how much electricity the system could deliver at one time, but it does not reveal how long the batteries could sustain that output.

No corresponding energy-duration figure, expressed in gigawatt-hours, was included in the available announcement materials. A 2.6 GW battery capable of discharging for one hour would provide a very different reliability service from a system capable of operating for four, eight or more hours.

The storage system could potentially perform several functions, including smoothing changes in data center demand, supporting the campus during generation outages, shifting electricity across hours, reducing peak grid withdrawals and making capacity available to the broader system during periods of scarcity.

Those capabilities will depend on the battery’s duration, operating reserve, interconnection rights, dispatch arrangements and the amount of capacity reserved exclusively for the data center.

The campus is being presented as a ratepayer-protection model

NextEra and Brookfield have connected the proposal to the White House’s Ratepayer Protection Pledge, which calls on data center developers and technology companies to secure new power supplies and pay for the delivery infrastructure their facilities require.

Under the published pledge framework, participating companies commit to paying for new generation, transmission, distribution and interconnection infrastructure rather than transferring those expenses to households and existing businesses.

The Paducah project’s dedicated generation and storage plan is intended to demonstrate that approach. However, a public commitment does not by itself establish how every cost will be treated in utility tariffs, power contracts, interconnection agreements or future regulatory proceedings.

The eventual ratepayer effect will depend on who finances the infrastructure, which assets enter a regulated utility rate base, how network upgrades are allocated, what minimum payments the data center must make and whether the project uses less power than originally forecast.

What the project could mean for data center energy design

The scale of the Paducah proposal reflects a broader change in data center development. Instead of relying solely on available utility capacity, developers are increasingly pairing computing campuses with generation, storage and dedicated grid infrastructure.

The Paducah design is not a conventional renewable microgrid. Its planned supply includes a substantial amount of natural-gas generation, and the available materials do not establish that the campus would be capable of fully disconnecting from the regional grid.

It nevertheless incorporates several features associated with large-scale campus energy systems: dedicated generation, battery storage, coordinated utility service and the potential to contribute resources to the wider grid.

The project could provide a test of whether a data center can bring enough energy infrastructure to cover its own demand while also improving regional capacity. That outcome will depend on the final technical design and binding commercial agreements rather than the announced capacity figures alone.

What remains uncertain

The project remains subject to negotiation and execution of definitive documentation. The announced $100 billion represents a planned investment program, not capital that has already been spent or contractually committed.

Developers have not publicly disclosed the battery’s energy duration, the number and type of generating units, fuel-supply arrangements, emissions profile, water requirements, detailed interconnection studies or the allocation of infrastructure costs among participating entities.

The 2028 initial-operation target and 2032 full-development date are also forward-looking schedules. Large generation, transmission, data center and storage projects can face changes caused by permitting, equipment availability, environmental review, financing, utility studies and customer demand.

What happens next

Brookfield, NextEra, DOE and the participating utilities must complete lease negotiations, power-supply arrangements, interconnection studies and definitive project agreements. The developers will also need environmental reviews, permits and construction approvals for the individual energy and computing facilities.

Future disclosures should clarify the battery’s duration, how much generation is reserved for the campus, when power may be supplied to the grid and what contractual protections will prevent unfinished or underused infrastructure from shifting costs to other electricity customers.
