Energy storage encompasses a range of technologies that use mechanical, chemical, or thermal processes to absorb energy, store it, and then dispatch it as useful. Technologies include batteries, capacitors, flywheels, compressed air energy storage, pumped storage, hydrogen storage, and heating and cooling energy storage.

Benefits of Energy Storage: Energy storage offers reliability, flexibility, and efficiency of usage, which makes it easier to integrate clean energy sources in the electrical grid system. Storage deployment has the potential to deliver huge savings to Massachusetts ratepayers by reducing energy costs, peak capacity, the cost of ancillary services, wholesale market costs, transmission and distribution costs, and costs associated with the integration of distributed energy resources.

Energy Storage Use Cases: There is currently a wide range of potential use cases for energy storage technologies in Massachusetts. Use cases include ownership of storage assets by investor-owned utilities or municipal light plants, residential, commercial, or industrial behind the meter deployments, and microgrid and resiliency related deployments.
