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.

Temelin Nuclear Plant Likely to Start in September

LCG, July 24, 2000--One unit of the controversial nuclear power plant nearing completion near Ceske Budeovice in the Czech Republic could start up in late August or early September, according to the U.S. company called in to bring the Soviet-designed facility up to Western standards.

Westinghouse Electric Co. said Friday it had completed installation of fuel assemblies in the 1,000 megawatt Unit 1 of the Temelin nuclear power plant and the facility would begin "critical testing," meaning a nuclear reaction would be taking place, late next month or in early September.

The Temelin plant, which has been under construction for 15 years, has been the subject of heated diplomatic objections from neighboring Austria, whose government is opposed to nuclear power.

With the Czech application to join the European Union contingent in part on upgrading the plant to meet Western standards for safety and operation, Westinghouse was called in and awarded five contracts which included replacement of the entire instrumentation and control system, supply of nuclear fuel and associated components, the diagnostic and monitoring system, and the radiation monitoring system; and developing emergency operating procedures.

The company said its work will make Temelin equal to any advanced nuclear power plant in the world. Jeffery L. Pelusi, director of European Projects for Westinghouse Nuclear Automation, said "The Temelin project is without question the most complex integrated information, control andprotection system ever installed."

Pelusi added "Once operational, Temelin will provide the Czech Republic with clean, efficient nuclear energy that is produced in a nuclear power plant that is both economical and safe."

The Bohemian city of Ceske Budeovice is known by Germans as Budweiss, and for centuries beer brewed there has been called Budweiser. That has long been a bone of contention between the Czech city and Anheuser-Busch of St. Louis.
