Project Overview

Revolution Storage is a battery energy storage system currently in the early stages of development by Flatiron Energy in Revere, Massachusetts. Upon completion, the Revolution facility will be capable of storing up to 800 megawatt-hours (MWh) of energy and will provide reliable electricity to local homes and businesses during periods of high demand. The facility is anticipated to begin operations in 2029.

Power capacity — 200 MW

This is the system’s maximum power output at any given time.

1 megawatt (MW) = 1,000,000 watts.

Real-world example:

200 MW of power would light up 2 million 100-watt light bulbs.

Energy capacity — 800 MWh

This is the maximum amount of energy the system can store.

1 MW of power sustained for an hour = 1 MWh.

Real-world example:

800 MWh is enough energy to power around 40,000 Massachusetts households for a month.

Community Impact

Community benefits

Revolution Storage will deliver significant environmental, economic, and infrastructure benefits to the City of Revere and the broader region throughout the project’s development, construction, and operation.

‍

During construction, the project is expected to generate approximately $17.8 million in new local earnings, create around 100 local jobs, and contribute millions of dollars in tax revenue over its lifetime. In addition, the project will establish a Host Community Agreement with the City of Revere to ensure sustained, long-term community benefits.

Environmental impact

Battery storage is key to enhancing grid dependability. Revolution Storage will store and distribute power generated by solar, wind, and other energy sources, making it more accessible when it’s needed most.

Community resilience

Energy storage benefits residents by improving the reliability of the power grid. Batteries provide safe, reliable energy to residents, reducing the risk of blackouts and the need for more expensive energy generation.

Supporting local reliability and resilience

Revolution Storage sits at a critical intersection of regional energy demand and growing climate pressures. The Revolution project site is located adjacent to a key portion of ISO-New England’s transmission system, enabling efficient interconnection.

‍

As Massachusetts experiences more frequent extreme weather events and increased strain on its electrical system, grid reliability and resilience have become essential to protecting residents, businesses, and municipal services. Strategic energy infrastructure investments in Revere help ensure a stable, dependable power supply while supporting the state’s transition to a cleaner energy future.

Clean Energy Focus

This project will strengthen Massachusetts’ electric grid by providing flexible capacity to support renewable energy integration and reduce reliance on older, more expensive fossil-fuel–based generation during peak demand. In addition to contributing to long-term emissions reductions, the project will deliver local benefits, including increased tax revenue, temporary construction jobs, and infrastructure investment. By prioritizing safety, environmental stewardship, and community compatibility, the project reflects a forward looking approach to meeting energy needs while supporting Revere and Massachusetts’ long-term economic and environmental goals.

Energy Storage Explained

Battery energy storage systems (BESS)

Battery energy storage systems (BESS) provide reliable energy by storing surplus electricity for use when demand increases. The result is cleaner air, reduced pollution, and more affordable energy. Battery storage is a critical component of Connecticut’s clean energy strategy. It supports the state’s goal of deploying 1,000 MW of energy storage by 2030 to meet emissions-reduction and grid-reliability targets.

Aligning energy demand with renewable supply

Renewable energy sources such as solar and wind generate electricity intermittently, and energy demand often does not align with peak renewable production. Battery storage helps balance this mismatch by absorbing excess generation.

Saving energy for when it’s needed most

Batteries capture and store energy produced by renewables and other sources so it can be used later. Without storage, excess clean energy that is not immediately consumed would otherwise be lost.

Reliable energy when demand peaks

During periods of peak demand, batteries release stored energy back onto the grid, helping prevent blackouts and reduce grid instability. Battery systems also provide essential grid services throughout the day, improving overall system reliability and resilience.
