Making Sense of Energy Storage: How Storage Technologies Can Support a Renewable Future

Environment America Report

Energy storage technologies can be an important part of that electric grid of the future, helping to assure reliable access to electricity while supporting America’s transition to 100 percent renewable energy. To get the most benefit out of energy storage, however, policy-makers and the general public need to understand how energy storage works, where and when it is necessary, and how to structure public policy to support the appropriate introduction of energy storage.

Energy storage can make a valuable contribution to our energy system.

  • Energy storage can capture renewable energy produced in excess of the grid’s immediate needs for later use. In California, solar and wind energy plants were forced to halt production more than one-fifth of the time during 2016 because the power they produced was not needed at that moment.
  • Energy storage can help utilities to meet peak demand, potentially replacing expensive peaking plants.
  • Energy storage can extend the service lifetime of existing transmission and distribution infrastructure and reduce congestion in these systems by providing power locally at times of high demand.
  • Energy storage can improve community resilience, providing backup power in case of emergency, or even allowing people to live “off the grid,” relying entirely on clean energy they produce themselves.
  • Energy storage can provide needed ancillary services that help the grid function more efficiently and reliably.
