Storage in State/Utility Planning• Integrated Resource Planning (IRP)
– Requiring utilities to fully evaluate storage as an alternative to traditional generation resources
– Arizona (APS), New Mexico, New Orleans, Washington (also moving toward sub-hourly IRP modeling
• Evaluation of Non-Wires Alternatives– Strategic deployment of DERs (frequently storage) to defer,
mitigate, or obviate need for certain T&D investments– Maine, New Hampshire, New York, Rhode Island
![Page 7: Status of Energy Storage Policy in the U.S. file• Integrated Resource Planning ... Colorado, Florida (TECO), Maryland, Minnesota, Nevada, North Carolina • Customer-Sited Storage](https://reader034.fdocuments.us/reader034/viewer/2022050718/5e17e01b6dda9a202e64fe2d/html5/thumbnails/7.jpg)
Storage in Planning & Market Access• Distribution System Planning
– Not specific to storage, but helps identify most beneficial locations for storage on the grid
– Hosting capacity analyses– Connecticut, Michigan, Nevada, New York, Rhode Island
• Wholesale Market Rules– Market access and compensation rules for storage– CAISO, ISO-NE, MISO, NYISO, PJM

Storage Policies• Procurement Targets
– Massachusetts, New York– California, Oregon previously established targets– Under consideration in Arizona, Nevada, and others
• Interconnection Rules – updating rules to include clear standards for energy storage– Arizona (state’s first interconnection rules), Colorado, Florida
(TECO), Maryland, Minnesota, Nevada, North Carolina• Customer-Sited Storage Compensation – net
metering eligibility, role of storage in successor tariffs– California, Colorado, Hawaii, Massachusetts, New York, Rhode
Island

Rate Design for Storage• Rate structures drive adoption of behind-the-meter
storage• Time-of-use rates, demand charges• Arizona utilities examined dedicated tariffs for customers
with battery storage

2017 Action on Energy Storage Incentives
![Page 12: Status of Energy Storage Policy in the U.S. file• Integrated Resource Planning ... Colorado, Florida (TECO), Maryland, Minnesota, Nevada, North Carolina • Customer-Sited Storage](https://reader034.fdocuments.us/reader034/viewer/2022050718/5e17e01b6dda9a202e64fe2d/html5/thumbnails/12.jpg)
Energy Storage Incentives• Maryland – SB 758 (enacted May 2017) created the first
state tax credit for energy storage in the country• California – Self Generation Incentive Program – April
2017 decision increased program funding, set aside 85% for energy storage
• Nevada – SB 145 (enacted in May 2017) creates a new energy storage incentive program – currently being implemented in a PUCN proceeding

Takeaways• Already a lot of policy and regulatory activity around
storage occurring across the country• Activity is highly varied, taking place across a number of
different topic areas• Key areas of activity include information gathering and
identification of policy barriers (studies, pilots), incorporating storage into planning, and examining how these resources are compensated
• Significant policy activity around storage expected in 2018
