EIA Estimates Record U.S. Electric Generating Capacity Additions in 2026, with Solar in the Lead

LCG, February 20, 2026--The EIA today issued an "in-brief analysis" that estimates U.S. power plant developers and operators plan to complete a record installation of 86 GW of new, utility-scale electric generating capacity that is connected to the U.S. power grid in 2026. Last year, 53 GW of new capacity was added to the grid, which was the largest capacity installation in a single year since 2002. Thus the estimate of 86 GW of new capacity in 2026 is a whopping 33 GW greater than the year prior. It should be noted that over 20 GW of the 86 GW of new capacity this year is estimated to be completed in December.

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.

The new BESS will provide critical dispatchable capacity to complement growing intermittent renewable capacity, support the ERCOT grid and increase grid resiliency. According to the announcement, the system includes Energy Vault’s proprietary X-Vault integration platform using Energy Vault’s proprietary UL9540 certified B-VAULT product, and VaultOS Energy Management System to control, manage and optimize the BESS operations. Energy Vault’s system architecture provides customer optionality with both battery and inverter suppliers, while unique AC-coupled and DC-coupled configurations provide the drop-in flexibility needed for any project.

"As one of the largest battery storage developers and operators in the U.S., we look for partners who can keep pace with our ambition and scale. With more than 2,500 MWh in operation or construction, we’re excited to continue building with Energy Vault at this critical site and appreciate their ability to deliver solutions tailored to our needs,” said Jupiter Power's Chief Technology Officer.

Energy Vault's Chief Commercial and Product Officer stated, “Today’s expansion of our partnership with Jupiter Power stands as a testament to the strength of our team’s collaborative approach to delivering reliable, safe, and efficient energy storage solutions to customers. Jupiter’s BESS projects portfolio has reached a critical mass in ERCOT and we’re proud to continue serving as a partner to Jupiter Power in the ultimate endeavor to decarbonize the grid in an economically effective fashion.”

The Energy Vault and Jupiter see today’s announcement as another step forward in their ongoing partnership, which began in 2022.
