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.

Exelon Announces Early Retirement of Nearly 3,000 MW of Carbon-Free Nuclear Capacity
LCG, June 3, 2016--Exelon Corporation yesterday announced that it will close two nuclear plants in Illinois, given the lack of progress on Illinois energy legislation. The Clinton Power Station in Clinton will close on June 1, 2017, and the Quad Cities Generating Station in Cordova will close on June 1, 2018. The two plants have lost a combined $800 million in the past seven years, despite being two of Exelon's best-performing plants.
Exelon's president and CEO stated, "This is an extremely difficult day for the 1,500 employees who operate these plants safely and reliably every day, and the communities that depend on them for support. We have worked for several years to find a sustainable path forward in consultation with federal regulators, market operators, state policymakers, plant community leaders, labor and business leaders, as well as environmental groups and other stakeholders. Unfortunately, legislation was not passed, and now we are forced to retire the plants."
The Clinton Power Station began commercial operation on April??1987 under the ownership of Illinois Power. The plant includes a single boiling water nuclear reactor, with a generating capacity of approximately 1,080??MW. The present reactor operating license was issued April 17, 1987 and will expire September 29, 2026.
The Quad Cities Generating Station is a nuclear power plant, with a total electric generating capacity of approximately 1,870 MW. The units began operations in 1972. In 2004, the Nuclear Regulatory Commission (NRC) approved a 20-year license extension for both reactors that would extend the license through December 14, 2032.
The Illinois legislative session has not ended; however, the path forward for consideration of the Next Generation Energy Plan legislation is not clear. Thus Exelon has initiated the necessary steps to shut down the two nuclear plants. These steps include: making permanent shutdown notifications to the NRC within 30 days; terminating capital investment projects required for long-term operation of the plants; immediately taking one-time charges of $150 million to $200 million for 2016, and accelerating approximately $2 billion in depreciation and amortization through the announced shutdown dates; and cancelling fuel purchases and outage planning.
Retiring the plants will have a significant economic and environmental impact on the region.
