1 Leading the Way in Electricity TM Southern California Edison s AutoDR Program Open Automated Demand Response (OpenADR) Outreach Collaborative Connectivity Week June 8,

2 About Southern California Edison Largest electric utility in California Peak load 23,300 MW (2007) 4.6 million customers Serving Los Angeles metro area (50,000 sq. miles) Peak load growth higher than energy growth Increased electric intensity Rates too low at daily peak and too high off peak Dramatically increasing costs to serve peak load Climate change concerns 24,000 22,000 Peak Load Growth 61% 59% PG&E SCE LADWP SDG&E MW 57% 20,000 55% 18,000 53% 16, MW Demand Load Factor 51% 2007

3 SCE Demand Response Today System Peak (2008) Reliability DR Large 23,303 MW 634 MW Reliability DR Residential/Small Commercial Reliability DR Ag Pumping/Other Price Response Programs Total DR 695 MW 63 MW 231 MW 1,623 MW Total DR % of System Peak 7%

4 AutoDR is a communication and technology platform designed to: Provide customers with automated, electronic price and reliability signals Provide customers with the capability to identify and automate site specific demand response strategies What is AutoDR? SCE s AutoDR program delivers event signals for Critical Peak Pricing (CPP) and Demand Bidding Program (DBP)

5 Why AutoDR? Evidence of more DR with enabling technology Makes DR more sustainable and more reliable Facilitates shallow DR which allowing more customers to participate

6 Target Audience for AutoDR Large commercial & industrial customers Largest 12,000 accounts (>200kW) represent 28% of peak demand All customers over 20kW represent 47% of peak demand s with building energy management systems (EMS) Not Residential Eleven buildings at the Tri-City Corporate Centre in San Bernardino, including the Lakeside Tower (shown), can reduce load by 721 kilowatts during a demand response event under SCE s Auto Demand Response program.

7 Current AutoDR Participants Industry Type Number of Sites Estimated Load Reduction (kw) kw Percent of Total Chemical Products 2 13, % Electrical Equipment 2 4, % Office Buildings % Petroleum Products 2 1, % Primary Metals % Retail % Transport Equipment 5 2, % Total 27 22,972 A total of 27 service accounts Baseline peak demand representing approximately 45 MW Estimated load reduction of nearly 23 MW Average reduction of 50% (industrial participants) Average facility reduction of 15% (nonindustrial participants)

8 Key Challenges to Implementation Automation is highly technical and requires special knowledge of both building/process systems and communication technologies Perceived loss of control by plant managers Energy use practices change over time as personnel and building conditions change discusses AutoDR with SCE Acct Rep & TA Contractor. enrolls in program TA Contr. performs AutoDR preliminary assessment determines go/no-go TA Contr. performs AutoDR Technical Audit SCE Acct Rep presents Technical Audit results to customer reserves funds Tech Coordinator contracts with Controls Vendor Vendor designs sequence of operations, programs/installs AutoDR system Tech Coordinator conducts system test submits payment invoices to SCE receives rebate incentive

9 What Next? Adopt OpenADR as a standard for commercial applications Define OpenADR Collaborative s role to include addressing some of the challenges OpenADR Facilitates implementation + Reduces cost of technology = greater customer participation!
