Definitions» Residential Storage: storage for domestic end user Customer: homeowner Purpose: energy cost management, maximizing solar PV Fleets: yes, but emerging Ownership: customer and third party 4 2015 Navigant Consulting, Inc. All rights reserved.
Business Cases» Community : challenging because storage must be ratebased, high transaction cost, early commercialization failed, some utilities found it was not cost effective» Commercial: requires peaky and somewhat predicable loads to allow for correct sizing of battery system, hardware and software are sometimes packaged as separate offers with separate business cases, requires demand charges» Residential: driven largely by subsidies, requires low interconnection fees, typically paired with solar PV (everywhere except Japan), and used to maximize self consumption 5 2015 Navigant Consulting, Inc.

Final Lessons» For behind the meter storage, rate structures and interconnection fees are critical to the business case» The best customers for commercial storage have volatile energy costs, and consistent peakiness One failure to cut a peak can ruin the business case for an entire month Value add is in the software and controls The next frontier will be data and data services around commercial storage» Community storage hinges on PUC acceptance, very few standard offers in the market keep costs high 10 2015 Navigant Consulting, Inc.
