Energy Vault to build 220MWh of battery storage projects for Jupiter Power in Texas and California


Gravity-based energy storage company Energy Vault will deliver and optimise battery energy storage systems (BESS) totalling 220MWh for developer Jupiter Power in Texas and California.

The company, best known for its novel energy storage technology based on raising and dropping weights to charge and discharge energy, is now providing conventional BESS projects alongside its core product. It laid out its project pipeline for each division in its results presentation last week, in which it claimed to expect nearly US$700 million in revenues over 2022 and 2023 combined.

The company will supply a 100MW/200MWh BESS at a Jupiter Power Facility near Fort Stockton, Texas, which will provide energy and ancillary services to ERCOT, the state’s grid operator, according to a press release. Note that the ERCOT market doesn’t have centralised capacity auctions so any wholesale energy sold is to buyers in the market.

Energy Vault, which went public earlier this year, will also construct and commission a smaller 10MW/20MWh BESS unit for Jupiter in Carpinteria, California. The BESS will participate in the CAISO Resource Adequacy programme, the framework through which the grid operator ensures there is enough energy to meet demand (again, without centralised capacity auctions).

The projects Energy Vault is delivering for Jupiter will utilise its business unit Energy Vault Solutions’ (EVS) proprietary system design and Energy Management Software (EMS), which are technology-agnostic, according to the company.

The company launched EVS in November 2021, reported at the time by The division is headed by John Jung, the former CEO and president of battery storage and EMS pioneer Greensmith Energy until its acquisition by Wärtsilä in 2017.

“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, CCO, Energy Vault.

Jupiter Power has 654MWh of BESS projects in operation or the commissioning stage in the ERCOT market, which has previously reported on.
