EPIC 2.19 – Enable Distributed Demand-Side Strategies & Technologies Overview: • Technical Demonstration project to test both residential and commercial aggregated storage solutions. • Demonstrate if aggregated customer-sited utility controlled BTM energy storage resources can be reliably and cost- effectively used: • To reduce peak loading or absorb distributed generation • As a non-wires approach to address capacity constraints as compared with other technologies used by the utility for the same purpose, such as replacing transformers and/or reconductoring 13
Project Objective, Reasons and Value Objective Demonstrate distributed demand-side technologies and approaches • Demonstrate effectiveness of aggregated customer-sited BTM energy storage systems to reduce peak load or absorb PV generation on the distribution system • Demonstrate reliable communications with BTM energy storage resources with real time visualization and control • Evaluate ability of BTM energy storage solutions to simultaneously provide service to utility and customer • Evaluate BTM energy storage meter measurement accuracy Reasons Precursor to the fulfillment of Assembly Bills AB and Proceedings • AB 2514 and AB 2868, which require local, publicly-owned electric utilities to procure viable and cost- effective energy storage systems. • Support Distribution Resources Plan R.14-08-013 proceeding, evaluating aggregated BTM customer energy storage as a non-wires alternative to address capacity constraints as part of the Integrated Distribution Planning Process. Value Help guide long-term BTM energy storage vision • Reliability improvement utilizing storage as an additional grid resource or backup power • Opportunities for customers to lower energy costs and help utilities defer upgrades which provides additional savings • Storage integrated with photovoltaics can provide additional opportunities for renewable resources 14
