ESA supports its members across the entire energy storage industry. Our principles of inclusion, competition and fairness are evident throughout our work to ACCELERATE markets, CONNECT members and EDUCATE all stakeholders.

ACCELERATE Bringing about change for the benefit of the entire industry

ESA represents its members’ interests directly with centers of influence in Washington, D.C. and in state capitals around the country. With your support, the ESA continues to:

  • Work closely with regulators at the federal and state levels to open fair, competitive markets for the widespread adoption of energy storage.
  • Ensure regulatory policies reflect the value provided by energy storage and remove barriers to its integration.
  • Develop best practices at the state level to affirm the positive economic impact of energy storage projects for ratepayers.

Public policy conversations around storage are evolving. Join us to develop policy positions that will accelerate the deployment of competitive and reliable energy storage. Policy Working Groups are available to Policy Partners and Leadership Circle members.


Get customized education on the policies impacting your business today. As more of your employees get involved in your storage business, bring them up to speed quickly through this intensive introduction to the U.S. storage policy landscape. Policy in a Box seminars are offered twice a year to members for a highly interactive and intimate educational experience. Private, customized sessions are available per request.
