Community Storage In R.1012007, we issued a staff report that established our definition of Community Storage as a distribution energy storage resource. Community Storage is typically associated with a cluster of customer load, whether residential, campuslike complexes, or commercial development. Battery capacity may be combined to serve the load in aggregate, or may be dispersed through a residential or commercial development, and may serve the following functions: Providing storage capacity for excess output from smallscale renewable energy sources; Providing smoothing and power quality regulation for intermittent resources; Providing backup power capability during outages. In this proceeding, the CPUC sought to understand the status of existing and planned distributionlevel community storage pilot programs; any barriers to developing distributionlevel community storage; and what policy options, if any, should be pursued to further address the barriers identified. In comments SCE identified four different discrete applications that could be considered community storage: Storage located at a distribution feeder that is interconnected directly to the utility distribution grid… and operated by the utility for the purpose of distribution reliability. A series of small batteries interconnected [behind the meter] as several customer locations within the same local area, aggregated together and operated (in at least some hours) by the [utility distribution company]. These batteries may be operated to provide customer bill management as well as to provide services to the local distribution grid. Storage interconnected [in front of the meter] within a community, and operated to provide services to local customers…
