Industry Trends and Regulatory Drivers
3
• Renewable Portfolio Standard: Requires 33 percent of delivered power to come from renewable sources such as solar, wind and geothermal by the year 2020
• Greenhouse Gas (AB32): Requires reduction in GHG emissions to 1990 levels by 2020
• Energy Storage (AB2514): Requires 1,325 megawatts of storage by 2020
• Distribution Resource Plan (AB 327): Requires utilities to identify optimal locations for distributed resources throughout service territories
• Prioritizing environmental sustainability
• Changing customer expectations
• Accelerating technology advancement facilitating conservation and self-generation
• Increasing use of distributed energy resources and transportation electrification
• Flattening demand for electricity
Industry Trends Regulatory Drivers
Commission Goals for Distribution Resources Plan
• Supporting California’s 2030 and 2050 GHG reduction targets
• Beginning the process of moving towards full integration of DERs in distribution system planning, operations, and investments
• Modernizing the electric distribution system to accommodate two-way flows of energy and energy services throughout the IOUs’ networks
• Enabling customer choice of new technologies and services that reduce emissions and improve reliability in a cost efficient manner
• Animating opportunities for DERs to realize benefits through the provision of grid services
Creating a “plug-and-play” distribution grid for DERs

Projects
Phase 2: 2018-2019• Determine impacts on
distribution system • Deploy sensors and
communications infrastructure
• Identify optimal locations for DER
Phase 1: 2016-2017• Develop tools and
methodologies• Share data with third parties• Plan and design sensors and
communications infrastructure
Phase 3: 2018+• Develop
procurement policy
• Enable distribution system markets
The CPUC envisions a phased approach

Locational Net Benefits
• SCE’s objective is to identify optimal locations, likely in form of heat maps, where DERs could provide a high benefit value
• SCE’s locational net benefits methodology (LNBM) identifies DER benefit components and describes how to quantify them
• Identification and communication of locational net benefits can drive DERs to locations where they can provide the most benefit with cost effective means
