Energy Vault will supply a 100 MW (200 MWh) battery energy storage system at a Jupiter Power Facility near Fort Stockton, Texas, which will provide energy and ancillary services to ERCOT.

Energy Vault will additionally construct and commission a 10 MW (20 MWh) battery energy storage system for Jupiter Power in Carpinteria, California, which will participate in the CAISO Resource Adequacy program and provide resiliency to California.

The Jupiter Power battery energy storage systems will utilize Energy Vault Solutions’ (EVS) proprietary system design and EVS’ Energy Management Software which are designed for optimal grid resiliency and economic energy dispatch regardless of the underlying storage technology.

LUGANO, Switzerland & WESTLAKE VILLAGE, Calif. & AUSTIN, Texas — (BUSINESS WIRE) — Energy Vault Holdings Inc. (NYSE: NRGV) ("Energy Vault" or the “Company”), a leader in sustainable, grid-scale energy storage solutions, and Jupiter Power (“Jupiter”), a leading battery energy storage developer and owner/operator of utility-scale battery energy storage projects in the United States, today announced the signing of two contracts whereby Energy Vault will supply equipment, engineering, procurement, construction, balance of plant services and the energy management software for two of Jupiter’s battery energy storage projects.

The projects include a 100 MW (200 MWh) battery energy storage system near Fort Stockton, Texas, which will provide energy and ancillary services to ERCOT, and a 10 MW (20 MWh) system in Carpinteria, California, to provide grid services through participation in the CAISO Resource Adequacy program as well as energy resiliency in Southern California. The projects will provide critically needed dispatchable capacity to these electricity markets and are expected to be completed in 2023.

The systems will utilize Energy Vault Solutions’ (EVS) proprietary integration platform and powered by EVS’ innovative energy management software platform, which started development nine months ago in November 2021, as previously announced. EVS leverages advanced software architecture and optimization algorithms and enables the integration and orchestration of multiple energy assets under a multitude of use cases.

"With today’s inaugural EVS-enabled battery energy storage projects announcement supporting a market leader in storage infrastructure and analytics like Jupiter, we are delivering on our comprehensive energy storage solutions strategy introduced just nine months ago,” said Marco Terruzzin, Chief Commercial Officer, Energy Vault. “We are seeing strong demand for our EVS-enabled energy storage solutions on a global basis due to the unique ability of our platform to integrate and deliver both short and long duration (EVx) energy storage technologies.”

“Jupiter is pleased to be working with Energy Vault to expand our existing battery energy storage portfolio with these two new projects,” said Michael Geier, Chief Technology Officer of Jupiter Power. “As the largest developer and operator of battery energy storage projects on the ERCOT grid, we see a strong need to continue to execute innovative storage solutions to help relieve grid strain. We are also excited to be building our first project in California, where grid conditions continue to demonstrate a strong need for additional battery energy storage capacity.”

Jupiter currently has 654 MWh of battery energy storage projects in operations or commissioning in Texas and more than 11 GW of additional projects in development in several target markets from California to Maine. Jupiter’s projects are critical to decarbonizing the U.S. electricity grid by providing non-emitting generation to support and firm the penetration of renewable electricity resources, namely solar and wind, while increasing grid resiliency and reliability.
