Southern California Edison Overview •
•
• •
An Edison International company, SCE is one of the nation’s largest investor‐ owned electric utilities, with more than 120 years of service. Serves a population of 14 million people, via 4.8 million business and residential accounts in a 50,000‐ square‐mile service area within central, coastal and Southern California. 17% of Customer Load delivered via Renewable Energy Delivering that power takes 93,500 circuit miles of line connecting 1.5 million poles, 683,000 transformers and 737,000 area and street lights and the days and nights of 13,000 employees. 2
Solar Photovoltaic Program (SPVP) Overview •
On March 27, 2008, SCE filed the SPVP application with the CPUC and on June 18, 2009 received its’ approval. The SPVP is a two‐fold program: – 250 MW of Utility‐Owned Generation – Details of which are: • Typical installation to be from 1 to 2 MW on commercial warehouse rooftops. Projects can be larger or smaller than and up to 10% ground‐ mount • Installed at 50 MW per year with an average cost of $3.50/Watt (W), approximately half the current cost for large commercial PV installations. • If the program is successful, SCE may seek additional authority to expand the program to 500 MW. • SCE was earlier granted in August, 2008, the ability to establish a $25 M Memo Account thus allowing the utility to install up to 5 MW of PV at an average cost not to exceed $5.05/watt. – 250 MW from IPP Renewable Generation PV Solicitation – SCE will coordinate an annual solicitation for approxiately 50 MW per year for 5 years (250 MW total) of IPP Photovoltaic Power to be provided under long‐term PPAs. The price to be paid for this generation will be capped at the utility LOCE (26 cents per kWH). Other terms to be similar to UOG constraints. 3
SPVP Objectives • Market Transformation – Program large enough to impact costs/resources – Shift Focus towards California – Develops trained PV Installation workforce • Adds 1.0% to RPS Goals by 2014 • Supports CSI Goals: 167,000 equivalent roofs • Leverage SCE’s Solar Expertise – – History with solar – Utility implementation coupled with energy efficiency deployment • Advance R&D and PV Industry Knowledge – Grid impacts – intermittency, power quality, circuit saturation – Business Modeling • Deployment of PV on circuits in a distributed manner – Does not require any transmission upgrades • Can provide generation in critical AQMD emissions sensitive areas, such as the Inland Empire, with No Green House Gas Emissions 4
SPVP Goals • • • • • • • • • •
•
Cost Initial Phase – Install up to 5 MW at a cost of less than $5.05/watt Future Larger Deployment – Install 250 MW over 5 years at an average cost of $3.50/watt compared to $6.80/watt for CSI commercial installs. Schedule Average PV installation rate of 50 MW per year for the next 5 years. The average on‐site construction time will be kept to 45 days for a 1 MW project and 60 days for a 2 MW project so as to minimize impact to the building tenant Quality Safety/Environmental – No recordable accidents from SCE or contract personnel involved in the program. All environmental issues handled properly. System Performance – No adverse electrical impacts to distribution system. Unit output at or above manufacturer specifications. Project Administration and Reporting – All project cost forecasted and recorded in an accurate and timely manner. All project related contracts executed and administered in a professional manner. Minimize change orders. Continuous Process Improvement and Documentation –Document process flow so as to serve as a learning base for future installations. Develop best practices. 5

Balance of System Technology Issues PV Industry maturing – areas for improvements include: •Roof Protection, longevity •DC Wiring •Copper vs. Aluminum Wiring •Cable Tray vs. Conduit •1000 V. vs. 600 V. DC systems •Combiner Boxes •String Monitoring •Disconnect Switches •PV Site Security – roof and ground •Racking - Seismic Constraint vs. Floating system (penetrations, adhesion, etc.) •Operations and Maintenance (O&M) Issues •Performance Monitoring •Cost Effective Cleaning Programs •Emergency Call-out services •PV Systems grid impacts - Var Support, remote cut-off switches, etc.
12
SPVP Major Materials Procurement Update • SunPower Panels ‐ Master Services Agreement (MSA) in place for up to 200MW of panels. • Trina Panels ‐ Master Services Agreement (MSA) in place for 45MW of panels. • Panel Racking ‐ MSA reached with Sunlink for up to 45MWs. • Inverters ‐ MSA in place with Satcon to provide minimum of 75% of program needs. • Transformers / Wiring – SCE’s normal procurement channels to be used. • Switchgear, Balance of Systems – Competitive bid process to be used on Tranche Basis, Shoals Electric provided initial set of sites. 13
Interconnection • Not Net Energy Metering (NEM) • Will interconnect directly to 12 or 16 kV circuits, not to host load • “Merchant Plant” interconnected under Wholesale Distribution Access Tariff (WDAT) application • Large influx of WDAT applications has created challenges • 15% circuit penetration – 2MW limit • NREL High Penetration of PV Study on‐going 14
ISO Scheduling Improvements ISO requires: •Special metering and Data Acquisition System (DAS) •Power to be scheduled on an hourly basis, can be aggregated up to the ABank (220 KV) •Participating Intermittent Renewable Program (PIRP) minimizes scheduling costs. •SCE will fine-tune forecasting of intermittent resource As Modified Original

Update on SPVP Installations • Site #1 Construction completed on September 19, 2008 Commissioning completed on Nov. 1, 2008. • Site #1 costs currently estimated at $11.5M or $4.90/watt, below the $5.05/watt Initial PV panel system. First Solar was the successful bidder for the solar panels. ProLogis is the roof landlord as well as the general contractor for the installation. Electrical sub‐contractor was Gregg Electric, an IBEW‐approved vendor. A project labor agreement was signed with IBEW Local 47 for all labor associated with these installations. 17
