February 13, 2026: Black Rock-backed Jupiter Power has closed a $500 million facility to support expansion of its BESS portfolio across the US.

Jupiter said on January 28 the senior secured revolving loan and letter of credit facility boosts the company’s existing $225 million facility, originally closed in September 2024.

CFO Jesse Campbell said: “This upsizing represents another big step in Jupiter Power’s growth and underscores the confidence our banking partners have in our ability to continue delivering high-quality BESS projects with long-term contracted cash flows.”

Jupiter has nearly 8,000MWh of BESS projects operating, under construction or under contract, with a development pipeline exceeding 12GW nationwide.

For the latest facility, Barclays Bank, HSBC Bank USA, ING Capital, National Association, Société Générale and SMBC acted as coordinating lead arrangers.

Paul Snow, head of renewables Americas for HSBC Infrastructure Finance, said the expanded facility reflected the strength of Jupiter’s platform and a shared commitment to scaling critical energy storage infrastructure and supporting US energy security.

Last November, Batteries International reported that Peak Energy was to supply up to 4.75GWh of its sodium-ion BESS systems to Jupiter.

US-based Peak said the systems are to be introduced between 2027 and 2030 with a total contract value more than $500 million.
