Clean energy storage,
where communities need it most
Tremont develops grid-scale energy storage with municipalities and communities across the Northeast and Mid-Atlantic. Energy storage built close to the communities it serves with no upfront cost.
We work alongside communities
to build storage that fits them.
Tremont works with municipalities, towns, and communities across the Northeast and Mid-Atlantic to develop long-duration energy storage: batteries that store electricity when supply is high and deliver it back to the grid when demand peaks. Each project is sized to fit the land, the grid connection, and the community's actual goals.
We specialize in smaller, distributed sites: the kind that fit on town-owned parcels, utility land, or underutilized commercial property. We lease or purchase the land and fund every cost ourselves, from permitting through decades of operation. Your community stays in control and earns revenue from the arrangement; we handle the complexity.
Our systems store 4 to 12 hours of electricity and discharge it during evening peaks, when grid stress is highest and prices follow.
Storage sited close to a substation reduces strain on local distribution lines, improving reliability for the neighborhoods around it.
Wind and solar don't follow demand. Storage captures surplus generation and delivers it when homes and businesses actually need it.
One partner from site assessment to decommissioning.

Power When It's Needed
Reliable power during peak demand, reducing costs for your utility and delivering a more stable, affordable grid for your community.
Built for Your Site
We develop projects from community-scale installations to small and medium utility deployments. Project size follows the site: your land, your grid connection, and your community's needs set the parameters.
Community-Safe Siting
Our non-flammable, water-based technology can be safely sited in commercial, residential, and industrial areas. Safety regulations require a 10-foot property-line setback for our systems, one third of what lithium-ion requires.
Turnkey Partnership
We lease or purchase your land, fund and build the project, and operate it for the long term. You take no financial risk and earn annual revenue from the arrangement. One partner, start to finish.
Who We Work With
We work with municipalities, utilities, and commercial facilities. The structure of each deal is different. The commitment is the same.
Turn underutilized land into long-term revenue.
If your town has a parcel near a substation or utility corridor, we can develop it at no cost to you. We lease or purchase the land and make your grid more reliable for every resident.
Add storage without the capital burden.
We bring the capital, technology, and expertise. You get storage that reduces peak demand costs, defers transmission upgrades, and lets you absorb more renewable generation, with no upfront investment.
Protect your operations and cut costs.
We partner with manufacturers, logistics facilities, and large commercial sites to deploy on-site storage that reduces demand charges, shields against outages, and supports your sustainability goals.

Non-flammable chemistry.
30-year lifespan. Zero hazardous waste.
Vanadium redox flow batteries use a non-flammable, water-based electrolyte, making thermal runaway physically impossible and toxic gas emissions nonexistent under any operating condition.
Unlike lithium-ion batteries, vanadium redox flow batteries (VRFBs) store energy in tanks of non-flammable, water-based electrolyte rather than in solid cells. The chemistry operates at ambient temperatures with minimal heat generation. Thermal runaway is physically impossible, and no toxic gases are emitted under any condition.
The vanadium electrolyte remains stable over decades of use, cycling 20,000+ times with no measurable capacity loss, supporting 30+ years of operation. At end of project life, over 98% of system components are recyclable with no hazardous waste.
Power and energy capacity scale independently: add electrolyte to increase storage duration, or add cell stacks to increase power output. This flexibility makes VRFB ideally suited to the range of community, municipal, and utility projects we develop across the Northeast and Mid-Atlantic.
Curious whether a VRFB project would work on your land?
No upfront cost. Long-term revenue. A cleaner, more reliable grid for your community.
Zero capital cost to your community. We fund it, build it, and run it.
Steady, long-term revenue from land that's already yours.
From first conversation to power flowing. Simpler sites move faster.
System components and electrolyte are fully recyclable at end of life. No hazardous waste disposal required.
Storage built close to where it's needed.
Most energy storage projects are built on remote land. Ours are built inside the communities they serve.
Right-sized for land in communities
Most storage developers are looking for 50-acre industrial tracts. We're looking for 2 to 20 acres near a substation: land a town owns but doesn't use, a utility easement, a parcel that never found a buyer. We lease or purchase from municipalities, utilities, and private landowners.
Safe enough to be a neighbor
Vanadium flow batteries store energy in a water-based electrolyte that can't burn and produces no toxic fumes. No fire risk. No hazardous emissions. No need for the large separation distances that lithium-ion installations require. That's what makes it practical and safe to place our sites in the communities they serve.
The benefit goes to the people nearby
When storage is sited close to the homes and businesses it serves, the grid stability happens right there, on the local lines that matter to that community. During a summer demand spike or after a storm, that storage is already in position to help. A remote project improves the regional grid. Ours improves yours.
