As the demand for grid-connected storage grows, states and utilities have an opportunity to unlock its unique operating capabilities to benefit the grid and more efficiently integrate clean energy resources. However, challenges related to how storage systems are evaluated and treated within the interconnection process can increase project costs and delay storage deployment. To assist states in streamlining the process, the BATRIES project team identified storage interconnection barriers emerging in multiple jurisdictions and provided solutions vetted through a collaborative process and informed by external experts, culminating in this Toolkit. The Toolkit includes background information and guidance on eight critical interconnection topics that should be considered as jurisdictions seek to integrate storage in a more efficient and cost-effective manner. As grid constraints and storage adoption increase, the ability to recognize and enable the flexibility and other capabilities that storage can offer will become more critical. State interconnection rules and practices will need to continue to evolve to integrate storage efficiently and address other issues that may emerge.
