Cost Components of Electric Rates

Electric Utilities Collect Program Funds through Various Surcharges, Procurement Expenditures, and Distribution Rates Electric Public Goods Charge, a surcharge funding: – Electric energy efficiency (EE) – Public interest electric R&D (PIER) Gas Public Purpose Program, a surcharge supporting: – Natural gas energy efficiency (EE) – Public interest gas R&D (PIER) Funds collected through Electric Distribution component supports: – Self-Generation Incentive Program – California Solar Initiative – Low Emission Vehicle Program Funds collected through Natural Gas Distribution component supports: – Self-Generation Incentive Program – California Solar Initiative Thermal program Electricity “Procurement” component (generation and purchased power components of electric rates): – Renewable Portfolio Standard (RPS) electric resource commitments 3 3

RPS Procurement Process CPUC approves RPS procurement plans IOUs hold annual solicitation IOU rank bids pursuant to “least-cost, bestfit” methodology IOUs negotiate bids, execute contracts • Independent evaluator oversees solicitation, bid evaluation, and negotiations • Bilateral contracts (negotiated outside of a competitive solicitation) are also eligible Once the IOU executes contract, submits to the CPUC for approval 7

CPUC Energy Division generally does not credit the RPS program with having incented the development of these mostly-existing projects. 8

Self-Generation Incentive Program (SGIP) SGIP provides incentives for non-solar Distributed Generation (DG) technologies. Goals of SGIP § Reduce peak load demand (historical goal from inception in 2001) § Reduce greenhouse gas emissions (per SB 412 in 2009) Budget § $83 Million program budget per year § $75 Million for incentives, $8 Million for program administration § Incentive budget split 50% for renewable and 50% for non-renewable § Budget allocated across IOUs as % of natural gas sales. § No new budget collection allowed after 12/31/2011 per SB 412. § SGIP Program authorized to operate through 2016. Incentives Offered on a Capacity basis (not Performance) § Wind = $1. 50/Watt 14 § Fuel Cells = $2. 50/Watt (+ $2. 00/watt if using biogas) § Storage = $2. 00/Watt § + 20% incentive adder for California Suppliers (per AB 2667, 2008) § Fuel Cells using biogas with a California Supplier = $5. 00/watt 14
