The Largest Battery Energy Storage Solution in New England
On February 11, 2026, a groundbreaking step towards renewable energy was achieved with the inauguration of the Cross Town Energy Storage facility in Gorham, Maine. Operated by Plus Power, this 175-MW/350-MWh battery energy storage system is now the largest of its kind in New England. Governor Janet Mills celebrated the completion of this project, highlighting its role in providing reliable power and cost savings for residents in Maine, especially during peak demand and extreme weather conditions.
Why Battery Energy Storage Matters
Battery energy storage systems (BESS) like Cross Town are crucial in modernizing the energy grid. They allow for power generation during periods of low consumption, storing surplus energy from renewable sources like wind and solar, and releasing it when demand spikes. This promotes the effective use of renewable resources, aligning with Maine’s ambition to have 90% of its electricity sourced from renewables by 2030.
Supporting Infrastructure and Future Goals
The Cross Town facility is strategically located adjacent to Central Maine Power’s 115kV Moshers substation, a spot identified as experiencing significant congestion in the transmission grid. As Plus Power’s CEO Naveen Abraham noted, this project not only eases congestion but also supplements the grid's stability amidst the reduction of conventional power generation sources.
With the entire Cross Town project made up of 156 units of Sungrow's PowerTitan battery technology, the storage facility can deliver continuous power equivalent to serving around 19,000 homes for about 2.5 hours. This capability becomes vital during peak demand periods, notably during extreme weather events like Winter Storm Fern.
Strengthening Maine's Renewable Energy Goals
Plus Power's investment in Gorham underscores the state's commitment to renewable energy development. The Cross Town facility is a significant leap toward Maine's target of installing at least 400 MW of battery storage capacity by 2030. As noted by Christina Hoffman, Senior Director of Planning at Plus Power, the facility offers the dispatchable services typical of a conventional power plant but with significantly fewer environmental impacts, including no water usage and negligible emissions.
Economic and Environmental Benefits
Transitioning to energy storage not only helps in managing demand but also supports local economies by creating jobs in emerging renewable energy industries. Governor Mills emphasized that projects like Cross Town play a critical role in shielding Maine from the volatility of fossil fuel markets, thereby creating sustainable job opportunities while achieving environmental goals. Moreover, energy storage systems can help stabilize prices across the region, a benefit welcomed by both consumers and industry stakeholders alike.
Looking Ahead: The Future of Energy Storage
The significance of the Cross Town Energy Storage facility extends beyond its immediate infrastructure benefits. As other states and regions observe developments in Maine, this project could serve as a model for future energy storage installations nationwide. With more than 11 GW of projects under its belt across over 20 states, Plus Power is at the forefront of the energy storage revolution, illustrating the potential for BESS in promoting a more resilient and sustainable energy landscape.
As we look to the future, one can expect that the influence of facilities like Cross Town will catalyze the expansion of battery storage technologies, thereby further integrating renewable energy sources into the power grid. A sustainable energy transition is not just a path we embark on, but a necessity for resilient communities and environments.
