Energy Vault has signed a 1.25 GW commercial agreement aimed at solving one of the hardest problems in the AI infrastructure buildout: getting dependable electricity to compute sites fast enough. The company will supply battery energy storage systems, grid-forming power conversion systems and its AI infrastructure control software as part of an integrated power platform. The first deployment will support hyperscaler AI data centers in Texas, with a turnkey power-generation EPC partner and Caterpillar gensets forming the generation layer. Energy Vault expects the contract to generate roughly $500 million to $600 million in revenue during the second half of 2026 and throughout 2027.

Energy Vault Turns Power Into A Compute Bottleneck

The deal reflects a shift in how hyperscalers approach AI capacity, where access to electricity can determine how quickly new computing capacity reaches production. Instead of treating generators, batteries, converters and controls as separate procurement decisions, the agreement packages them into a coordinated power architecture designed around AI workloads. The initial 1.25 GW deployment already has support from a hyperscaler customer contract, giving the project a commercial anchor rather than leaving the platform dependent on speculative capacity planning. That matters because traditional utility interconnection schedules can take far longer than AI infrastructure developers want to wait.

The architecture targets fully integrated, off-grid power systems that can start supporting compute before a permanent grid connection becomes available. Energy Vault expects initial deployments to arrive within four to twelve months, creating a potential speed-to-power advantage for operators racing to commission AI capacity. The modular design can later incorporate utility electricity as campus requirements expand, rather than forcing customers to abandon the initial generation architecture. It can further accommodate renewable generation and distributed energy resources as individual campuses evolve.

Texas Becomes The First Major Test

Texas provides the first commercial setting for the 1.25 GW platform, giving the agreement significance beyond Energy Vault’s own revenue expectations. The state has become a major destination for large-scale computing projects, while developers continue to confront the practical limits of grid availability and interconnection timing. An off-grid architecture can change the sequencing of a campus build by allowing power infrastructure to arrive before the permanent utility connection. That creates a path for developers to decouple at least part of the compute schedule from the grid-connection schedule.

The four-to-twelve-month deployment window will become one of the most closely watched aspects of the agreement. If the model works at commercial scale, it could give hyperscalers another option for bringing capacity online in power-constrained markets. The approach does not eliminate the need for eventual grid integration, but it can create a bridge between immediate computing demand and longer infrastructure timelines. For AI operators, that bridge could become as strategically important as the underlying generation capacity.

A Power Platform, Not A Single Product

The agreement brings together two different areas of industrial expertise. The unnamed national turnkey power-generation EPC contractor contributes experience across natural-gas reciprocating engines, gas turbines, diesel generation and solar PV, along with capabilities involving emerging hydrogen technologies. Energy Vault contributes utility-scale battery storage, energy management software and hybrid plant integration expertise. Together, the companies are positioning the platform as a repeatable infrastructure package for hyperscalers and neocloud providers.

That combination gives the project a broader commercial ambition than a conventional BESS sale. The customer receives generation, storage, conversion, engineering, procurement, construction and digital control as components of one architecture. Energy Vault can then pursue additional deployments without rebuilding the commercial structure around every individual project. The strategy turns the initial 1.25 GW contract into a potential reference model for larger AI infrastructure programs.

Energy Vault Sees A New Infrastructure Category

Robert Piconi, Chairman and Chief Executive Officer of Energy Vault, framed the deal as a transformation in how critical power infrastructure must serve AI computing.

“Artificial intelligence is fundamentally changing how critical power infrastructure is designed, deployed and operated,” said Robert Piconi, Chairman and Chief Executive Officer of Energy Vault. “Customers are no longer procuring individual technologies—they require integrated power infrastructure capable of delivering reliable, always-on electricity at unprecedented speed and scale. With this agreement we have created a highly differentiated platform that combines industry-leading power generation, intelligent energy storage and advanced power plant software into a single integrated solution purpose-built for AI infrastructure. As our largest single contract executed to date, this milestone agreement represents another important step in Energy Vault’s strategic evolution from an energy storage technology pioneer into an integrated energy infrastructure provider. More importantly, it establishes a repeatable commercial platform that we believe can support substantial future expansion as hyperscaler AI infrastructure investments continue to accelerate globally.”

Executive Perspective at Energy Vault

The strategic power infrastructure partner described Energy Vault’s technology as a central component of the broader plant architecture. Its executive said, A senior executive at Energy Vault’s strategic power infrastructure partner commented, “Energy Vault’s BESS, grid-forming technology and software platform are central to this solution. By integrating those systems into our modular plant design, we can bring large blocks of dependable power online quickly while maintaining the performance, scalability and flexibility that hyperscale campuses require.” Those comments point to the larger bet behind the contract: Energy Vault wants to move up the infrastructure stack. Its position no longer centers solely on selling storage technology, but on orchestrating the electrical systems that determine how much compute a campus can actually operate. The commercial opportunity comes from combining hardware, controls and project delivery into a package that customers can replicate across multiple locations.

The 1.25 GW Deal Could Be Only The Beginning

Energy Vault and its partner plan to pursue additional AI infrastructure projects involving hyperscalers and neocloud operators. Their target markets include locations where limited grid capacity and long utility interconnection schedules create obstacles for new computing campuses. The companies intend to pursue behind-the-meter and bridge-power configurations that can support workloads while permanent grid connections progress. That strategy gives the initial Texas deployment a role as both a revenue-generating project and a reference architecture for future sites.

AI infrastructure is increasingly forcing data center developers to think about electricity as a deployable computing asset rather than a background utility service. Energy Vault’s 1.25 GW agreement captures that change by connecting generation, storage, power conversion and software around the behavior of AI workloads. The Texas project will test whether that integrated approach can deliver capacity quickly enough to matter in a market where compute schedules increasingly collide with grid schedules. If it succeeds, the more interesting story may not be the 1.25 GW itself, but the emergence of power platforms designed specifically to unlock the next generation of AI capacity.
