Energy Vault signs 1.25 GW power deal for AI data center in Texas

Energy Vault Holdings, Inc. (NYSE: NRGV) announced a strategic commercial agreement to supply 1.25 gigawatts of integrated power infrastructure for hyperscaler AI data centers, with initial deployments planned in Texas over the next four to twelve months.

Under the agreement, Energy Vault will provide battery energy storage systems, grid-forming power conversion systems and AI infrastructure control software. An unnamed national turnkey power generation engineering, procurement and construction contractor will contribute generation assets, including Caterpillar gensets, and EPC capabilities.

The combined solution is designed to operate independently of utility grid interconnection, allowing AI compute capacity to come online without relying on traditional utility timelines. The modular architecture is intended to support future integration of utility power, renewable generation and other distributed energy resources as campus requirements grow.

Energy Vault said the agreement is backed by a hyperscaler customer contract and described it as the company's largest single contract to date. The company expects the deal to generate approximately $500 million to $600 million in revenue in the second half of 2026 and in 2027. Additional details are expected to be discussed during an earnings call on August 11, 2026.

"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," said Robert Piconi, Chairman and Chief Executive Officer of Energy Vault.

The companies said they intend to pursue additional opportunities with hyperscaler, neocloud and AI infrastructure customers in markets where grid capacity constraints and extended interconnection timelines are driving demand for rapidly deployable power solutions.
