The Eastern Pequot Tribal Nation sits minutes from the New London energy corridor, where grid congestion drives some of the highest wholesale electricity prices in New England.
A tribally owned battery storage facility on tribal land could earn revenue by charging when offshore wind and solar flood the grid, then discharging during peak demand windows.
One possible mechanism would be a negotiated intergovernmental memorandum of understanding with the Connecticut Public Utilities Regulatory Authority and ISO-New England that could grant the tribe a preferential interconnection queue position and capacity market participation rights.
One tribal member could begin by drafting a one-page letter to PURA’s chair requesting a technical conference on tribal energy asset participation, copying the tribe’s attorney and the state’s energy affordability advocate.
Within one year, a site feasibility study and interconnection application could be filed; within five years, a 20-megawatt battery asset could be generating millions in annual capacity and arbitrage revenue while stabilizing the regional grid.

The Seasonal Shoreline Energy Reserve — A Proposal for the Eastern Pequot Tribal Nation
The Eastern Pequot Tribal Nation occupies a small but strategically located land base in southeastern Connecticut, within sight of the transmission lines that carry power from Millstone Nuclear Station and the growing offshore wind fleet into the New England grid. Connecticut’s electricity prices are among the highest in the continental United States, driven by natural gas transmission constraints, aging transmission infrastructure, and aggressive renewable portfolio standards that have created a volatile market where prices can spike from under twenty dollars per megawatt-hour to over two hundred within a single day. The state is also a national leader in deploying battery storage, having enacted procurement targets and incentive programs that require utilities to contract for hundreds of megawatts of storage capacity by the end of this decade. Yet tribal nations in Connecticut have largely been absent from this market, despite holding land that could host storage infrastructure without the siting friction that plagues municipal and private developers. The gap is not technical feasibility or market demand; it is the absence of a legal and contractual pathway that recognizes tribal utilities as eligible market participants with a preferential right to connect to the regional grid.
The proposed mechanism is a seasonal resource management protocol, formalized through a tribally chartered utility authority that would operate a grid-interactive battery storage facility designed around New England’s four distinct grid seasons. Winter demand peaks are driven by electric heating and gas transmission constraints, summer peaks by air conditioning and transmission congestion, spring brings negative pricing from abundant hydro and wind, and fall shoulder months offer maintenance windows. A tribally owned storage asset could charge during spring overflow when wholesale prices approach zero or negative, discharge during summer and winter peaks, and participate in the ISO-New England forward capacity market by committing to be available during defined seasonal reliability windows. This is not novel technology; comparable structures exist in the form of municipal utilities in Massachusetts and New York that own and operate storage assets under similar market rules. The Hoopa Valley Tribe in California operates a tribally owned utility that participates in the California ISO energy markets, providing a named tribal analog for sovereign participation in wholesale electricity markets. The key legal interaction would be with the Federal Energy Regulatory Commission, which has jurisdiction over wholesale power sales, and with PURA, which regulates distribution-level interconnection within Connecticut. The tribe would need to obtain qualifying facility status under the Public Utility Regulatory Policies Act, secure a market-based rate authorization from FERC, and negotiate an interconnection agreement with Eversource, the local distribution utility.
The implementation roadmap could begin with a single tribal member or small working group spending the first month compiling the tribe’s existing land records, utility easements, and any prior energy studies, then requesting a meeting with the Connecticut Green Bank, which has financed storage projects across the state and has a statutory mandate to support environmental infrastructure in under-resourced communities. No budget or institutional authority would be required to make that call or to begin drafting the charter documents for a tribal utility authority, which could be modeled on publicly available templates from the American Public Power Association. By month six, the working group could seek to convene a technical advisory committee including an energy attorney, a storage developer, and a representative from ISO-New England’s interconnection queue team, with the goal of filing a formal interconnection request for a five-megawatt pilot facility by month twelve. The first-year milestone would not be construction; it would be a completed feasibility study, a filed interconnection application, and a term sheet from either a private storage developer or a project finance lender willing to structure a deal around the tribe’s tax-exempt status and the investment tax credit for standalone storage. From there, a four-year horizon could match the natural election cycle of the tribal council and the FERC permitting timeline, with the goal of a fully permitted, financed, and operational twenty-megawatt facility within four years, structured so that no single council election could halt construction once the power purchase agreement and interconnection agreement were signed.
Geographically, the Eastern Pequot’s land sits within the New London-Norwich transmission corridor, where the state’s highest-value grid nodes are located and where Eversource has reportedly identified capacity constraints that require local storage solutions. The tribe’s proximity to Millstone and to the substations serving Electric Boat and Pfizer’s Groton campus means that a storage facility would be physically close to both generation and load, reducing interconnection costs and transmission losses. Connecticut is not a PL-280 state, meaning the state does not have broad criminal or civil jurisdiction over tribal land, but utility regulation is a gray area where FERC and PURA authority overlap; a tribal utility authority would need to carefully structure its market participation to assert sovereign immunity in contracting while waiving it narrowly for FERC market registration purposes. The state’s renewable portfolio standard and storage procurement targets create a regulatory tailwind that a tribal utility could capture by positioning itself as a clean peak resource that also serves grid reliability, a framing that has helped municipal utilities secure favorable treatment in state energy policy.
The larger dividend could be political leverage through market participation. A tribally owned utility that earns revenue from wholesale electricity sales, capacity payments, and ancillary services would not be a grant-dependent program but a revenue-generating enterprise that could fund other tribal priorities, from housing to language programs, while giving the tribe a formal seat at ISO-New England participant meetings and FERC proceedings where energy policy is actually decided. Sovereignty in this context would mean owning the physical asset, controlling the data it generates, and holding contractual rights to market revenues, all of which could be structured to survive political turnover through a tribally chartered utility authority with staggered board terms and independent financial accounts. The Eastern Pequot could be the first tribal nation in Connecticut to participate in the regional wholesale electricity market as a storage owner, a position that would convert land that is too small for casino development or large-scale agriculture into a high-value energy infrastructure asset generating predictable, seasonal revenue for decades.
