Table of State Energy Storage Targets and Progress

Definitions & Abbreviations Data Sources Disclaimers Contact

Definitions & Abbreviations

This table includes all existing state energy storage procurement mandates, targets, and goals. These terms describe various ways states may set an intention to attain a specified level of energy storage deployment by a specific date, and the role of regulated electric utilities in helping realize that intention.

A Mandate is a goal with legal liability for non-attainment
A Target is a defined goal with measures for follow-through
A Goal is a number without defined accountability.

Some of the abbreviations used in this table are: kW (kilowatts), MW (megawatts), GW (gigawatts), kWh (kilowatt hours), MWh (megawatt hours), GWh (gigawatt hours), BTM (behind-the-meter, which refers to customer-sited installations), LDES (long-duration energy storage), and IOU (investor-owned utility).

Data Sources

Data on how much energy storage is installed or pending per state are based on the Pacific Northwest National Laboratory’s Energy Storage Policy Database.

Some of the data gathered on how much BTM storage is installed was gathered from state websites and from the U.S. Energy Information Administration (EIA).

Installed capacity data are taken from EIA's Preliminary Monthly Electric Generator Inventory.

Disclaimers

States define, count and report energy storage targets and procurement information differently. We have done our best to resolve these differences within this table, but some discrepancies are unavoidable. We encourage you to contact us with corrections.

The source of the installed capacity data represents front-of-the-meter (FTM) storage and may not fully include the installed capacity of behind-the-meter (BTM) storage. Some states do not require delineation or tracking between FTM and BTM storage, while others have specific carve-outs for BTM storage. Installed capacity data, taken from EIA's Preliminary Monthly Electric Generator Inventory, are based on best estimates of current generating capacity, but are not meant to reflect capacity commitments by the associated facilities.

Pending status is based on what utilities are planning to add to the system within the next year and not on interconnection queues.

A note about pumped hydro: In most states, pumped hydroelectric storage ("pumped hydro") is ineligible for inclusion towards energy storage goals/mandates/targets, as these installations largely predate state energy storage goals. In some states, such as California, large pumped hydro is ineligible but small pumped hydro may be eligible. Depending on how states define, count and report their energy storage data, installed capacity listed in this table may or may not include pumped hydro. When feasible, we have excluded pumped hydro from this table for states that do not count pumped hydro towards their goals/mandates/targets.

Additional 2 GW (1 GW of 12-hr storage and 1 GW multi-day) of LDES to be deployed between 2031 and 2037.	10,383 MW total (8,736 MW utility, 571 MW commercial, 1,076 residential) (4999 pending 1,193 MW BTM)	569%	In 2010, the California Legislature authorized the California Public Utilities Commission (CPUC) to consider establishing energy storage targets. The CPUC established their storage procurement targets in 2013, authorized by AB 2514. The procurement targets apply to the state's three largest Investor Owned Utilities. This goal has been achieved. LDES targets were set in August 2024 as part of AB 1373, which sets larger clean energy targets. Statewide energy storage installation data is tracked here.
