Jupiter Power has secured $1.4 billion in project financing across four separate transactions, supporting ten utility-scale battery energy storage system projects totaling 1.5 GW / 3.6 GWh of capacity across Texas and Michigan.
The transactions, which closed between April and July 2026, include senior secured project debt, tax equity bridge loans, and an investment-grade U.S. private placement. The deal package brings the developer’s total financing raised since inception to more than $3 billion.
The financing was structured across four separate portfolios. In July 2026, Jupiter Power closed a $536 million senior secured facility consisting of a construction term loan, tax equity bridge loan, and letter of credit facilities to fund the construction of three Texas projects, including Tidwell Prairie II, Bee Branch, and Barton Branch, with HSBC Bank USA and SMBC serving as lenders.
Prior to that in June 2026, the company closed a $281 million private placement rated BBB- by KBRA, collateralized by three operational projects comprising Tidwell Prairie I and St. Gall II in Texas, and Tibbits in Michigan, with AB CarVal and Nuveen as note purchasers.
In May 2026, the company secured a $294 million financing package from ING Capital and Societe Generale to construct the Grand Basin and Voyager I projects in Michigan, which interconnect within the MISO market. In April 2026, Jupiter Power closed a $258 million senior facility arranged by Societe Generale and MUFG for the Callisto II and Pamela Heights I projects in Harris County, Texas.
Jesse Campbell, chief financial officer of Jupiter Power, said the transactions reflect the depth and diversity of the company’s capital markets relationships and execution capabilities as it builds out its energy storage platform.
The expansion comes as the Texas energy storage market experiences rapid buildout. According to grid tracking data from Modo Energy, installed battery capacity in the ERCOT market reached nearly 15 GW (14.96 GW / 24.6 GWh) in early 2026, up from roughly 7.8 GW a year prior, solidifying Texas as one of the largest and fastest-growing regional energy storage markets in the nation.
The Texas-based company currently holds 5.6 GW / 19.7 GWh of battery storage assets operating, under construction, or under contract, alongside an active development pipeline exceeding 23 GW across major U.S. power markets.
