2017 Action on Energy Storage By Type of ActionStudies & InvestigationsAt least 32 States took action onenergy storage during 2017Policy, Regulation, and PlanningFinancial Incentives and RatesDeployment3 or More Types of Action
2017 Action on Energy Storage Studies and InvestigationsDCStorage-Specific StudyGrid Modernization or Other Study with Storage ComponentNo recent action
Storage Studies & Investigations Maryland – HB 773 (enacted May 2017)– Regulatory reforms and market incentives to increase use ofstorage; consult with stakeholders Nevada – SB 204 (enacted in May 2017)– PUCN to determine if a procurement target is in the publicinterest North Carolina – HB 589 (enacted July 2017) Vermont – Act 53 (enacted May 2017)– Opportunities for, benefits of, & barriers to storage deployment;regulatory options & structures available including cost toratepayers
2017 Action on Energy Storage Planning and Market Access2017 actionNo recent action
Storage in State/Utility Planning Integrated Resource Planning (IRP)– Requiring utilities to fully evaluate storage as an alternative totraditional generation resources– Arizona (APS), New Mexico, New Orleans, Washington (alsomoving 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
Storage in Planning & Market Access Distribution System Planning– Not specific to storage, but helps identify most beneficiallocations 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
2017 Action on Energy Storage PoliciesDC2017 actionNo recent action
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 clearstandards for energy storage– Arizona (state’s first interconnection rules), Colorado, Florida(TECO), Maryland, Minnesota, Nevada, North Carolina Customer-Sited Storage Compensation – netmetering eligibility, role of storage in successor tariffs– California, Colorado, Hawaii, Massachusetts, New York, RhodeIsland
Rate Design for Storage Rate structures drive adoption of behind-the-meterstorage Time-of-use rates, demand charges Arizona utilities examined dedicated tariffs for customerswith battery storage
2017 Action on Energy Storage Incentives2017 actionNo recent action
Energy Storage Incentives Maryland – SB 758 (enacted May 2017) created the firststate tax credit for energy storage in the country California – Self Generation Incentive Program – April2017 decision increased program funding, set aside 85%for energy storage Nevada – SB 145 (enacted in May 2017) creates a newenergy storage incentive program – currently beingimplemented in a PUCN proceeding
Energy Storage Incentives More action on incentives for solar storage, or addingstorage as an eligible technology to existing incentives– Massachusetts – SMART program storage adder– Florida – Property Tax Abatement– New York – Property Tax Abatement– Oregon – PACE Financing
2017 State & Utility Storage Deployment Proposals2017 actionNo recent action
State & Utility Storage Deployment Many proposals are for pilot projects– Eversource (Connecticut), Duke Energy (Florida) Some are non-wires alternative projects– AEP (Texas), Consumers Energy (Michigan) Others are part of microgrids– Emera (Maine), Rocky Mountain Power (Utah), Duke Energy(Indiana), ComEd (Illinois), Green Mountain Power (Vermont) Fewer are behind-the-meter storage deployment– Liberty Utilities (New Hampshire), Green Mountain Power(Vermont)
Takeaways Already a lot of policy and regulatory activity aroundstorage occurring across the country Activity is highly varied, taking place across a number ofdifferent topic areas Key areas of activity include information gathering andidentification of policy barriers (studies, pilots),incorporating storage into planning, and examining howthese resources are compensated Significant policy activity around storage expected in2018
