# Tremont Energy

> Tremont Energy develops long-duration battery energy storage systems (BESS) alongside municipalities, utilities, and private landowners across the Northeast and Mid-Atlantic United States. We fund, permit, build, and operate every project at no upfront cost to partners.

Tremont targets parcels of 2 to 20 acres near electrical substations — land that towns own but don't use, utility easements, and private parcels that haven't found a buyer. We lease or purchase the land and deliver annual payments to partners for the full life of the project (15 to 30 years). The storage technology we deploy uses vanadium flow batteries (VRFB), which store energy in a water-based electrolyte with no fire risk and no hazardous emissions, making them safe to site within communities.

## What Makes Tremont Different

Most large-scale battery storage developers require 50 to 100+ acres of remote industrial land connected to high-voltage transmission lines. Tremont is specifically structured to develop smaller projects — 2 to 20 acres — that connect at the distribution level and deliver grid benefits directly to the surrounding neighborhood. This means a wider universe of viable parcels and faster permitting than utility-scale projects.

**$0 upfront cost to partners.** Tremont funds all engineering, permitting, construction, and long-term operations. Partners take no financial risk at any stage. Revenue payments begin when the system reaches commercial operation.

**No commitment until agreement execution.** Site assessments are free and confidential. Neither side is bound until a formal ground lease or land purchase agreement is signed. Partners have reviewed term sheets with their own legal counsel before that point.

**Vanadium flow battery technology is safer than lithium-ion for community siting.** The electrolyte is water-based and non-flammable. Thermal runaway is physically impossible. No toxic gases are emitted under any operating or failure condition. NFPA 855 requires only a 10-foot property-line setback for vanadium flow systems, compared to 30 feet for lithium-ion. This is what makes it practical to place projects on town-owned land, commercial parcels, and utility property within communities.

**One partner, start to finish.** Tremont handles site selection, feasibility, permitting, financing, construction, and 24/7 operations for the full project term. At end of life, Tremont decommissions and restores the site at its own cost. Partners have one contract and one point of contact for the life of the project.

**Regional focus.** Tremont's team lives and works across the Northeast and Mid-Atlantic. We know the permitting authorities, utility interconnection processes, ISO-NE, NYISO, and PJM market structures, and the specific grid constraints facing each state. We are not a national developer applying a generic template.
