Summary: Revises Tariff WN U-60, updating schedules 611 (Residential Battery Energy Storage System Services), 667 (Purchases from Distributed Solar Photovoltaic Systems), and 686 (Solar Energy Credit Multi-Occupant Allocation Service) and adding new schedules 640 (Distributed Energy Resources Technology Demonstration) and 683 (Distributed Energy Resources products and services). These changes expand and clarify DER product definitions, such as solar and battery storage, while moving and consolidating duplicate definitions found in these schedules into a single new umbrella schedule (683) that the others now refer to. Additionally, schedule 640 creates a pathway for small-scale, short-term testing and demonstration of these DER products for technical feasibility before they are adopted more broadly.
