Energy Vault and Jupiter Power Announce New Agreement for Battery Energy Storage System in Texas

LCG, June 4, 2025--Energy Vault Holdings Inc. (Energy Vault) and Jupiter Power (Jupiter) today announced the signing of an agreement for the supply of an additional battery energy storage system (BESS) at a Jupiter site in the Electric Reliability Council of Texas (ERCOT) region. The initial BESS project, located near Fort Stockton, Texas, was completed in July 2024, with a storage capacity 100 MW/200 MWh. The new BESS project will add another 100 MW/200 MWh of capacity. Construction has commenced, and the project is expected to achieve commercial operations by the end of this summer.

New England ISO's Market Design Approved by FERC

LCG, Sep. 30, 2002--ISO New England's market design proposal, reflecting elements similar to those in the market run by PJM Interconnection, the mid-Atlantic grid operator, was largely approved by the Federal Energy Regulatory Commission last week.

The most important features of the proposal include "designated congestion areas," where known supply problems exist; a transition to locational marginal pricing within 18 months, in order to reflect the spatial variation in supply and demand; a system to auction financial transmission rights, by which owners of rights can earn revenue; and a demand management program to pay customers to reduce demand. The one area over which dissent was expressed was the level of installed capacity payments, which Commissioner Nora Brownell thought insufficient to draw long-term investment.

Although ISO New England and the New York Independent System Operator have discussed a merger between their market operations, some New England states have resisted, fearing that power supply would flow to New York. FERC commented that although upcoming market rules it will finalize in 2004 could lead to necessary changes in market rules, the current proposal "benefits customers by accepting improvements to New England's markets, including a day-ahead and real-time market, locational marginal pricing, mechanisms to mitigate market power, demand response programs, and a capacity resource mechanism."
