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.

Progress Selects Harris Nuclear Plant for New Reactor

LCG, January 24, 2006--Progress Energy Carolinas has selected its Harris Nuclear Plant site to evaluate the addition of new nuclear reactors to serve the growing electric demand of its customers. Westinghouse Electric Company was also selected as the vendor to provide the reactors.

Harris Nuclear Plant is located near New Hill, North Carolina. The existing plant is a single-unit, 900-MW facility that commenced commercial operation in 1987. The original site plan included four reactors, and the company states that the site offers sufficient land, water and electric transmission capacity to accommodate at least one new unit. Three other existing nuclear power plant sites were considered by Progress.

In November of last year, Progress updated its plans with the Nuclear Regulatory Commission (NRC) and announced that it planned to submit combined operating license (COL) applications for a site in the Carolinas and a site in Florida. Each COL is to include up to two reactors at each site. The company stated that the application for the COL could be filed in late 2007 or early 2008. Given the NRC approves the application and Progress elects to proceed, construction could start in 2010, with operations commencing in 2016.

Progress selected Westinghouse Electric Company to provide its advanced new AP1000 reactors. The AP1000 reactors are each able to generate 1,100 MW of electricity and employ passive safety features that rely upon natural forces, such as gravity, to simplify design, improve plant reliability, and reduce costs. According to Progress, the AP1000 has 87 percent less cable, 83 percent less pipe, 50 percent fewer valves and 35 percent fewer pumps than the previous generation of reactors. The NRC approved the Design Certification for the AP1000 standard nuclear plant design on December 30, 2005.
