Our energy storage projects encourage community investment, lower emissions, support renewables, and improve air quality.

Building resilience
Flatiron builds grid reliability assets where they are most needed. The Northeast Corridor, between Washington, DC, and Boston, contains about 20% of the U.S. population on only 2% of its landmass—placing enormous weight on the region’s energy infrastructure. Flatiron’s projects are focused on alleviating these constraints, building resilience, and lowering emissions in this region and beyond.

Energy storage deployment is projected to bring $3.4 billion in net societal benefits to the electrical systems of New York, Massachusetts, and Connecticut by 2030. Flatiron contributes directly to these communities by investing in job creation, leading technical training programs, and fostering local partnerships.


Electric systems with energy storage reduce emissions by 32% more than systems relying solely on renewable energy generation. By storing excess renewable energy and minimizing the reliance on fossil fuels, Flatiron’s projects significantly contribute to the reduction of carbon dioxide emissions.
Bringing 3 GW of energy storage online can make solar projects three times more likely to meet high-demand hours. Flatiron’s energy portfolio not only enhances local clean energy capacity but also supports renewable energy projects in effectively meeting future demand.


Building storage projects in dense urban areas can assist cities in shutting down expensive and polluting power plants that are used to meet peak energy demand. New York City estimates that converting these power plants to battery storage facilities could reduce nitrogen oxide (NOx) emissions by 1,849 tons per high-ozone day.
