Stanford/SLAC VADER Workshop March 30, 2016 Erik Takayesu, P.E. Director, Electric System Planning and Modernization
Southern California Edison Distribution Resource Plan
Energy Policy Drivers in California
Assembly Bill 327 (AB 327) • Distribution Resources Plan (DRP) • Net Energy Metering Successor Tariff • Residential Rates Reform
Senate Bill 350 (SB 350) • 50% RPS by 2030 • 50% increase in building EE by 2030 • Integrated Resource Planning • Transportation Electrification • Governor’s strong support
Technology-promoting policies • Integrated Distributed Energy Resource
(IDER) proceeding • 1,325 MW Energy Storage mandate • Transportation Electrification (e.g. SCE’s
Charge Ready program)
Disadvantaged Communities • Expand opportunities for low-income,
environmental justice and other underserved segments to access clean energy resources
California’s Energy Policy primarily driven by decarbonization
2
SCE’s Guiding Principles 1. Promoting customer choice and customer engagement are key
objectives
2. The distribution grid can play a key role in reducing carbon in California
3. Safety, reliability, and resiliency must remain paramount objectives
4. Costs of electric service must remain affordable and equitably-apportioned to customers
5. Competitive processes for the selection of DERs should be utilized to the greatest extent possible

Distributed Energy Resource Proceedings
Expanded scope • Competitive solicitation
framework: product definition, rules, plans, standard contracts, “review groups,” and valuation methodology

DER installation for additional uses increases grid operation complexity; when DER portfolios are relied on as part of reliability, that complexity escalates
