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.

EPA Proposal on Mercury Limits Under Review

LCG, Mar. 16, 2004--The administrator of the Environmental Protection Agency (EPA), Michael Leavitt, has told the White House that analyses of an administration proposal to limit mercury emissions from power plants burning coal could lead the EPA to put forth a more stringent set of emission reduction guidelines.

In December, the Bush administration introduced a plan that would allow power generators to buy and sell credits for releasing mercury, similar to the system with sulfur dioxide. Limits on mercury would gradually lower the permissible amount of emissions. Since Leavitt became the EPA administrator, he has been taking part in meetings focused on the possible impact of that proposal, and has begun to evaluate criticisms of it by some environmental groups, state regulators, and a group of doctors that sent a letter to an office of the EPA dealing with children's health issues.

The White House has come out in favor of allowing power plants that achieve reductions before limits make them legally binding to receive credit for the reductions later. Critics of the proposal believe that such a provision would in effect delay the reduction of the ultimate goal of a 70% reduction in mercury emissions for seven, and perhaps as many as ten or more years. The current deadline is set for 2018.

Leavitt has said that the EPA's analysis is not yet finished, and will proceed before any changes are introduced to the original proposal. Coal-burning power plants are a major contributor to mercury emissions, and are thought to make up 40 per cent of the annual total caused by human activity.
