October 4, 2026 update: Jupiter Power has added a major financing milestone, but it is not a Trimount financing announcement. Its September disclosure covers 10 projects in Texas and Michigan. In Everett, the developer's public schedule still makes construction dependent on site cleanup, permitting and commercialization. In New South Wales, government endorsement means coordinated assessment, not permission to build. Jupiter Power's planned 700 MW / 2,800 MWh Trimount battery remains a useful test of what happens after a large storage project clears an important siting hurdle. The project would replace part of a former ExxonMobil oil terminal in Everett, Massachusetts, with four-hour storage connected to Eversource's Mystic Substation. Zoning relief advances that plan. It does not, by itself, establish that construction has started or that the facility can deliver electricity today. The same distinction matters in Australia. New South Wales selected 16 projects representing AU$34.4 billion in potential investment for its Investment Delivery Authority's first round of support. The government's own breakdown is 14 energy projects worth about AU$34 billion and two hotels worth AU$482 million , not 16 approved clean-energy projects.

What is verified at Trimount Engineering consultant VHB confirms that Jupiter secured zoning exemptions from the Massachusetts Energy Facilities Siting Board for the 700 MW Everett project. VHB says it provided civil engineering and testimonial support and will continue with owner's-engineer advisory work as the project moves through final design and construction. That is more precise than describing the decision as the final regulatory hurdle. The developer's project website , checked for this refresh, still describes Trimount as being in community outreach and permitting. It says environmental cleanup of its portion of the former fossil-fuel site is underway and on course to finish in 2026. Construction would follow full remediation and depends on successful permitting and commercialization. The stated operating window is the latter half of the decade, not a confirmed commissioning date. These statements should not be read as a new October construction update. They are the schedule currently available on the public project site. The sources reviewed here do not establish completion of remediation, a final notice to proceed or commercial operation. Readers should look for separate dated announcements of those milestones before treating the proposed capacity as available to the grid. 700 MW Planned discharge power 2,800 MWh Planned stored energy, equivalent to four hours at rated power Why four hours near Boston matters Power and energy measure different things. The 700 MW rating describes how rapidly a fully available system could discharge. Dividing 2,800 MWh by 700 MW gives a nominal four-hour duration. It does not mean the battery creates electricity or can support that output indefinitely. Charging availability, operating reserves, conversion losses and battery condition affect how it is dispatched in practice. The Mystic connection is central to the proposal. Storage near a major electricity-demand center can shift charging away from expensive hours and discharge when the system needs power most. Batteries can also provide fast-response grid services when configured and contracted to do so. Actual reliability value depends on interconnection capability, operating rules and the state of charge when a stressful event arrives, not just the nameplate number. The brownfield setting preserves another important part of the original story. A former petroleum terminal offers an opportunity to reuse industrial land near electrical infrastructure. It also introduces cleanup sequencing, civil-engineering and community-review responsibilities. Jupiter presents a stronger local tax base, improved reliability and support for decarbonization as project benefits. Those remain expected benefits of delivery rather than measured outcomes from an operating plant. The proposed Mystic connection is part of Trimount's grid value.

September's US$1.4 billion financing changes the company story The biggest new corporate development since the original March report is Jupiter's disclosure of US$1.4 billion across four financing transactions . Energy Global's September 17 report says the transactions closed between April and July 2026 and support 10 utility-scale projects totaling 1,500 MW / 3,600 MWh in Texas and Michigan. The structures include secured project debt, tax-equity bridge loans and a U.S. private placement. July: US$536 million for Tidwell Prairie II, Bee Branch and Barton Branch in Texas, with HSBC Bank USA and SMBC as lenders. June: US$281 million in a secured note issuance and letter-of-credit facility backed by the operating Tidwell Prairie I, St. Gall II and Tibbits assets. The report identifies a BBB- KBRA rating and AB CarVal and Nuveen as note purchasers. May: US$294 million supporting Grand Basin and Voyager I in Michigan's MISO market, with ING Capital and Societe Generale as lenders. April: US$258 million for Callisto II and Pamela Heights I in Harris County, Texas, with Societe Generale and MUFG as coordinating lead arrangers. The four reported amounts total US$1.369 billion, rounded to US$1.4 billion in the announcement. The new package demonstrates access to several kinds of capital and covers both construction and operating assets. It does not identify Trimount as a financed project . Neither a corporate borrowing facility nor debt raised for a different portfolio should be presented as proof that Everett has secured its own construction funding. The September report also gives Jupiter a combined 5.6 GW / 19.7 GWh of projects operating, under construction or under contract, plus 23 GW in development. Those categories matter: the combined figure is not an operating-fleet total, and the development pipeline is not committed construction. This is a more useful measure of company scale than adding every announced project together and calling it installed storage. NSW's AU$34.4 billion headline needs a correction The NSW Government's first-round announcement explicitly states that the Investment Delivery Authority's endorsement is not an approval. Projects must still undergo full merit-based assessments and comply with state and Commonwealth legislation and policies, including foreign-investment requirements where relevant. What proponents receive is a dedicated government concierge service, a planning-assessments team and support from a multi-agency investment taskforce. The aim is to resolve coordination problems that can delay complex projects. That assistance can be commercially valuable, but it is not an exemption from environmental assessment, a grid-connection agreement or a final investment decision. The 16-project count includes two hotel developments. Even the 14-project energy subset is not exclusively renewable generation or storage: the official list includes a Santos and Hunter Gas Pipeline gas project in Narrabri. The original characterization of the whole AU$34.4 billion as approved clean-energy investment overstated both the scope and the legal status of the announcement. The storage projects on the endorsed list Castle Group battery-storage proposals in Liverpool and Penrith. Neoen Australia's Great Western Battery in Lithgow. Lake Victoria Wind Farm's wind-and-BESS proposal in Wentworth. Pottinger Renewables' wind-and-battery proposal in the Edward River and Hay areas. Lake Lyell pumped-hydro storage in Lithgow and Burragorang Valley Green Energy's hydro-storage proposal in Wollondilly. The wider list includes the Hunter energy hub, Dinawan wind and solar proposals, Piambong and Yanco Delta wind projects, and the Port of Newcastle clean-energy precinct.
