3. Integration of Demand Response, Advanced Metering Technology and “Smart Grid” IOU Goal: –Previous goal was 2700 MW peak reduction, ~ 5 large power plants. –Now market-based with DR at “top of resource loading order” with EE. IOU investment: –Electric hardware roll-out concluding; –SoCalGas $1 Bil AMI through 2015. –Results: 12 million electric meters, 10 million gas meters, distribution automation grid operations information Ancillary business services? $ TBD. Up to market & customer choice to determine: E nd-user technology & software applications for Home Area Networks and energy management. E.g.: –In-home displays (using real time data) –Programmable control functions / smart appliances –Data analytics, energy education –Energy management services –Storage technologies for load shifting For more information from CPUC’s lead management staff: Smart Grid: Liza Malashenko, elizaveta.malashenko@cpuc.ca.govelizaveta.malashenko@cpuc.ca.gov Demand Response: Bruce Kaneshiro, bsk@cpuc.ca.gov

4. Distributed Solar – California Solar Initiative IOU Goal: 1950 MW, ~ 4 large power plants –Statewide 3000 MW goal (including public utilities and CEC’s New Solar Homes Partnership) IOU CSI program spending expected 2007 - 2016: $2.3 BILLION Expected total hardware investment: > $12 BILLION For more information: –www.gosolarcalifornia.comwww.gosolarcalifornia.com –CPUC’s lead management: Melicia Charles, mvc@cpuc.ca.gov California Energy Commission has New Solar Homes Partnership –Goal of 400 MW of solar PV installed on new homes Ancillary business services? –Solar production metering & reporting: $13 million/year –Solar leasing and power purchase agreement finance transactions (now over 50% of residential market)

5. Other Clean Distributed Generation IOU “Self Generation Incentive Program” (SGIP) spending 2012-2016: $250 million Expected hardware investment 2012-2015: $900 million for 150 MW; more if market reaches grid parity Ancillary business services? –Fuel –Metering –Maintenance services For more information: –http://www.cpuc.ca.gov/PUC/energy/DistGen/sgip/http://www.cpuc.ca.gov/PUC/energy/DistGen/sgip/ –CPUC’s lead management: Melicia Charles, mvc@cpuc.ca.gov
