The Toolkit and Guidance for the Interconnection of Energy Storage and Solar-Plus-Storage provides vetted, consensus-based solutions to eight regulatory and technical barriers to the interconnection of energy storage and solar-plus-storage systems to the distribution grid. These recommendations are based on over a year of research and analysis by utility and industry experts. The Toolkit also includes model language that utility regulators can use to update state interconnection rules to reduce the costs and time to safely interconnect energy storage and solar-plus-storage systems. The solutions are nationally applicable and can be applied in diverse states and markets across the U.S. Adoption of these recommended solutions can have a significant impact on how many distributed energy resources (DERs), like residential and commercial solar PV systems, can be added to the grid. The Toolkit is the result of a multi-year project called “BATRIES” (Building a Technically Reliable Interconnection Evolution for Storage), supported by a cooperative agreement with the U.S. Department of Energy Solar Energy Technologies Office. The project team is led by the Interstate Renewable Energy Council (IREC) and includes the Electric Power Research Institute (EPRI), the Solar Energy Industries Association (SEIA), the California Solar & Storage Association (CALSSA), utilities New Hampshire Electric Cooperative Inc. (NHEC) and PacifiCorp, and law firm Shute, Mihaly & Weinberger, LLP (SMW). Over the coming year, IREC and partners will conduct extensive training and educational outreach to drive adoption of the solutions across the country. Parties interested in receiving training or more information on the Toolkit can contact the partner team via the Toolkit website.
