Advantage Capital Secures $158 Million Tax Equity Investment for Massachusetts’ Largest Battery Storage Project
Advantage Capital, a leading impact investment firm specializing in innovative energy solutions, announced today the successful closing of a $158 million tax equity investment to support the Medway Grid Energy Battery Storage project in Medway, Massachusetts. This 250-megawatt (MW) battery energy storage system (BESS) represents the largest facility of its kind in Massachusetts to date and is among the largest within the Independent System Operator of New England (ISO-NE) region, which encompasses all six New England states. The project is being developed and managed by VC Renewables, the renewable energy development team within Vitol, a globally recognized independent energy trader and market leader.
Advantage Capital’s Energy Finance team structured the investment to leverage federal Investment Tax Credits (ITC), a critical financing mechanism that supports the deployment of clean energy technologies and helps bridge capital gaps for emerging energy solutions. These tax credits are instrumental in accelerating the development of large-scale energy storage projects, which play an increasingly vital role in modernizing the electric grid and meeting the rising demand for reliable power.
“Massachusetts has long been a leader in promoting clean energy innovation and supporting projects that strengthen grid resilience,” said Tom Bitting, Managing Director at Advantage Capital. “We are proud to partner with VC Renewables on the Medway project, which marks our first standalone BESS in the ISO-NE region. This project not only contributes to a more reliable and flexible grid, but it also provides meaningful economic benefits to the local community. Residents and businesses alike will see advantages in terms of grid stability, potential reductions in electricity price volatility, and increased local property tax revenues, which directly support municipal services and programs.”
Battery storage technology, particularly at utility scale, enables electricity to be stored during periods of surplus generation and released when demand is highest. This flexibility helps grid operators balance supply and demand more efficiently, improving overall system reliability. For example, energy generated overnight, when demand is low, can be discharged during peak periods in the afternoon and evening. The Medway project employs a front-of-the-meter (FTM) configuration, which connects directly to the electrical grid and allows power to be sold into wholesale markets. This design not only enhances grid stability and responsiveness but also ensures that the facility operates with zero on-site emissions, aligning with state and federal climate objectives.
FTM battery storage systems like Medway are critical as states, including Massachusetts, pursue long-term energy policy goals such as reducing carbon emissions, meeting renewable portfolio standards, and supporting decarbonization of the power sector. By improving grid efficiency and providing dispatchable energy resources, these systems help accommodate growing amounts of intermittent renewable generation from solar and wind, while also enabling more flexible, resilient grid operations.
The ISO-NE interconnection queue has seen significant growth in recent years, reflecting the increasing role of energy storage in the region’s power mix. As of February 2026, there were 37 battery storage projects actively under development. The Medway Grid Energy Storage project complements other large-scale facilities in the region, including the 175MW Cross Town system in Gorham, Maine, and the 150MW Cranberry Point project in Carver, Massachusetts. Together, these projects signify a broader trend toward integrating large-scale storage solutions to meet both current and future grid reliability needs.
The Medway project also aligns with the Massachusetts Clean Peak Energy standards, which were established by the Massachusetts Department of Energy Resources. These standards provide incentives for clean energy technologies and storage solutions that can either generate electricity or reduce electricity demand during periods of seasonal peak load. By meeting these standards, the Medway project helps the state achieve its dual objectives of decarbonizing the electricity sector and ensuring energy availability during critical peak periods.
Advantage Capital’s involvement in Medway is part of its broader Energy Finance Platform, which focuses on financing large-scale, innovative, and resilient clean energy projects. The platform supports investments across multiple technologies, including solar, wind, storage, and emerging solutions that contribute to a more sustainable and affordable energy ecosystem. By providing critical capital to these projects, Advantage Capital helps accelerate the transition to a cleaner and more reliable energy future for communities across the United States.
Since its inception, Advantage Capital has financed the development of more than 3.3 gigawatts (GWdc) of clean energy infrastructure, a capacity sufficient to meet the electricity needs of over 582,000 homes. Through these investments, the firm continues to demonstrate its commitment to leveraging financial expertise to deliver tangible environmental, social, and economic benefits. The Medway Grid Energy Battery Storage project represents the next step in this ongoing effort, combining innovative energy storage technology with strategic investment structures to drive both local and regional impact.
As the energy landscape evolves, utility-scale battery storage is increasingly recognized as a critical tool for achieving reliable, low-carbon power. The Medway project not only strengthens the grid in Massachusetts but also serves as a model for how public-private partnerships and structured investment mechanisms, such as tax equity financing, can accelerate the deployment of clean energy infrastructure. Advantage Capital project’s completion is expected to generate long-term economic benefits, including job creation during construction, operational employment opportunities, and additional tax revenues, further reinforcing its positive impact on the Medway community.
In collaboration with Vitol and its VC Renewables team, Advantage Capital’s investment in the Medway Grid Energy Battery Storage project exemplifies the firm’s strategic approach to supporting cutting-edge clean energy initiatives that deliver both financial and societal returns. By enabling the project to move forward, Advantage Capital is helping to pave the way for a more sustainable, resilient, and economically vibrant energy future in Massachusetts and the broader New England region.
