Research Interconnection Guidance for Residential Bidirectional EV Charging: A Utility-Informed Resource for Regulators Commissions and utilities are preparing by codifying definitions and updating energization and interconnection rules Terminology matters: there is misalignment between customer marketing terms and utility interconnection processes Energization and interconnection pathways need to address diverse bidirectional charging configurations and use cases. Commissions will need to consider the pros and cons of energizing versus interconnecting non-parallel home installations Electric vehicles (EVs) equipped with bidirectional charging can move beyond their role as energy consumers to serve as higher value dispatchable storage resources, delivering distributed storage, resilience, and other grid services. As more automotive manufacturers introduce bidirectional capability to their products, customer interest and adoption is likely to grow, particularly for home backup and bill savings use cases. Capturing this potential will require clear regulatory definitions, updated interconnection pathways, and proactive utility leadership. SEPA partnered with ten utilities to assess challenges and best practices for interconnecting bidirectional charging systems, also known as vehicle-to-everything. This report summarizes key insights to guide regulators as adoption grows, outlining near-term actions commissions and utilities can take to prepare. These include clarifying definitions, updating interconnection rules to address bidirectional capabilities, and establishing fair compensation for grid services, ensuring utilities, installers, and customers are aligned on how these systems interact with the grid.
