Louisiana Data Centre Lands 2.88GW Gas Plant and 700MW Battery

ONE Nuclear Energy has executed a binding letter of intent to develop a 2.88GW natural gas plant alongside a 700MW/2.88GWh battery energy storage system, co-located with a high-capacity data centre campus in Louisiana.

ONE Nuclear Energy has signed a binding letter of intent to build a 2.88GW natural gas power plant and a 700MW/2.88GWh battery energy storage system next to a high-capacity data centre campus in Louisiana, according to Energy Storage News. The two assets would sit on the same site as the load they serve, an arrangement that is quickly becoming the default template for hyperscale computing campuses in the American South.

The headline numbers are unusual in their symmetry. The gas plant is sized at 2.88GW of capacity; the battery system is sized at 2.88GWh of energy. Those are different units measuring different things — gigawatts describe how fast power can flow, gigawatt-hours describe how much energy is stored — and the coincidence is a reminder to read behind-the-meter announcements carefully. At 700MW of power output and 2.88GWh of storage, the battery would run for roughly four hours at full discharge on an illustrative basis, dividing energy by power. That is the duration band that most US grid-scale lithium-ion projects have settled into, because it matches the length of a typical evening demand peak.

Why gas and batteries are being bought together

Data centre developers are no longer content to queue for a grid connection. Interconnection waits in several US markets now stretch for years, and an AI training campus that cannot energise is an idle capital sink. The response has been to build generation on site and treat the utility connection as a backup rather than the primary source.

Gas turbines supply the round-the-clock baseload that dense computing racks require. Batteries do something the turbines cannot: respond within milliseconds. A large AI cluster can swing its draw sharply as workloads start and stop, and those swings are hard on thermal plant. A storage system sitting between the turbines and the servers smooths the ramps, covers the seconds and minutes while a unit comes up, and rides through short faults without a diesel start. It also lets the developer size the gas fleet closer to average load rather than to worst-case peak — the economic argument that has moved storage from an add-on to a line item in these deals.

The pairing has a second function. Turbine order books are long, and a battery can be delivered and commissioned faster than a combined-cycle block. Storage frequently arrives first on these sites, carrying early load while the gas plant is still under construction.

Louisiana's pitch to hyperscale load

Louisiana has become one of the more active states for very large computing campuses, and the reasons are practical rather than promotional: existing gas transmission infrastructure, industrial land at scale, a regulatory environment accustomed to permitting heavy energy assets, and proximity to Gulf Coast gas supply. A 2.88GW plant is not a peaker — it is a fleet-scale investment that assumes cheap, deliverable fuel for decades.

That is also where the questions sit. A project of this size has implications for state gas demand, for water use, and for who ultimately bears the cost if the co-located load changes shape. Behind-the-meter generation shifts those risks off the regulated ratepayer in principle, but only if the contractual structure holds. Regulators in several states have started probing large-load interconnection agreements for exactly this reason.

What a binding LOI does and does not settle

The word "binding" is doing real work here, and it is worth being precise about its limits. A binding letter of intent commits the parties to defined obligations — typically exclusivity, confidentiality, a development timetable and a path to definitive agreements. It is meaningfully stronger than a memorandum of understanding. It is not a notice to proceed.

Between an LOI and steel in the ground sit the items that decide whether a project of this scale is real:

• Offtake. A signed power purchase agreement with the data centre operator, at a term long enough to finance a multi-gigawatt gas fleet.
• Equipment. Turbine slots and battery cell supply, both currently constrained by demand from precisely this class of project.
• Fuel and interconnection. Firm gas transportation, and an agreement covering how the site interacts with the grid.
• Capital. Debt and equity commitments sized to the build, with the credit quality of the offtaker as the anchor.
• Permits. Air permits for the generation, environmental review, and local approvals.

None of those milestones were disclosed alongside the letter of intent, and the announcement did not put a figure on capital cost, a commissioning date or the identity of the data centre counterparty. Until an offtake contract is public, the project should be read as an advanced development position rather than a committed build.

The storage market reads it as demand

For the battery supply chain, the significance of a deal like this is the volume. A single 2.88GWh order is a material block of cells, and it is being driven by computing load rather than by a renewables mandate or a state procurement target. That is the structural shift underneath the current storage boom in the United States: batteries are increasingly being bought as infrastructure for load reliability, not only as a complement to wind and solar.

It filters down to lithium, nickel and graphite demand forecasts, and it changes the customer profile. A hyperscaler-backed project carries different credit and different timing pressure than a merchant storage developer chasing a capacity auction. Cell makers have noticed, and several have been reorienting output toward long-duration stationary product lines.

Equity markets closed higher on the day the deal surfaced, with the S&P 500 tracker (NYSEARCA: SPY) finishing at $765.16, up 0.44%, and the Nasdaq 100 fund (NASDAQ: QQQ) at $709.24, up 0.23%, as of the 20:00 GMT close on 2 September 2026. The Dow 30 tracker settled at $530.62, up 0.54%. Those moves say nothing about this specific project — ONE Nuclear Energy is not a listed name here — but they reflect the broader market's continued willingness to fund the AI infrastructure chain.

What to watch next

Three disclosures would tell investors whether the Louisiana scheme converts. The first is the data centre operator's name and the term of the power agreement. The second is turbine procurement, because the gas plant is the long-lead item and its delivery date will set the project's critical path. The third is the battery supply contract, which will indicate whether the storage arrives ahead of the generation — the pattern on comparable US sites — and which cell chemistry the developer has chosen.

Until then, the letter of intent is best understood as a marker of how the power problem behind the AI buildout is being solved: on site, with gas for the hours and batteries for the seconds.

Frequently asked questions

What exactly did ONE Nuclear Energy agree to?

ONE Nuclear Energy executed a binding letter of intent to develop a 2.88GW natural gas power plant and a 700MW/2.88GWh battery energy storage system in Louisiana, co-located with a high-capacity data centre campus. A binding LOI commits the parties to a development path but is not a final investment decision or a notice to proceed.

How long can a 700MW/2.88GWh battery run?

Dividing stored energy by power output gives roughly four hours of discharge at full rated output, an illustrative figure rather than a reported specification. That four-hour band is the standard configuration for US grid-scale lithium-ion storage because it aligns with the length of a typical evening demand peak.

Why pair a gas plant with a battery at a data centre?

Gas turbines provide continuous baseload power, while batteries respond in milliseconds to the sharp load swings that AI computing clusters produce. Storage smooths those ramps, bridges the time a turbine needs to come up, and allows the gas fleet to be sized closer to average demand rather than to worst-case peak.

Was the data centre operator named?

No. The announcement described a high-capacity data centre campus in Louisiana but did not identify the counterparty, disclose the term of any power purchase agreement, or give a capital cost or commissioning date. Those details are the key ones for judging whether the project converts into construction.

Why is Louisiana attracting projects of this size?

The state offers existing gas transmission infrastructure, proximity to Gulf Coast gas supply, large tracts of industrial land, and a permitting environment used to heavy energy assets. Those factors make it practical to build multi-gigawatt on-site generation rather than wait years for a grid interconnection.

What does the deal mean for the battery supply chain?

A single 2.88GWh order represents a large block of cells, and it is driven by data centre reliability needs rather than a renewables mandate. That reflects a structural shift in which storage is bought as load infrastructure, feeding demand for lithium, nickel and graphite and changing the customer credit profile for cell makers.
