4 What is SEIG? Goals of EPRI Solar Electric Interest Group Share best practices with a network of knowledgeable peers Participate in collaborative RD&D activities that help to define the future role of solar energy in the utility industry Enhance corporate experience and image as leaders in solar applications Stay abreast of advances in solar PV cost, efficiency, and business models for power production Better understand and define the role of central station solar (CSS) in the future generation portfolio Collaborate with industry organizations to develop joint projects (e.g., CSS database, utility business models) 4

9 Germany Fact Finding Mission Sponsored by SEPA and First Solar Participants: APS, Avista, BC Hydro, CPS Energy, PG&E, SRP, SCE, Southern Company Meetings with German utilities: Badenova EnBW Energie Baden-Württemberg AG RWE Transportnetz Strom GmbH Tours Solar Fabrik manufacturing plant Franhofer Institute First Solar 1.8 MW rooftop installation (Muggensturm) First Solar 432 kw ground mount installation (Karlsruhe) Phoenix Solar presentation at Remote Monitoring Facility (Ulm) 6.3 MW SunPower installation (Muhlhausen) Intersolar tradeshow 9

10 Solar Assisted Steam Cycles Conceptual design study and one or more detailed case studies to evaluate solar augmented steam cycles Focus on natural gas plants in first phase Case study includes solar technology review, site assessment, integration analysis, and development of generic plant layouts with workable drawings and schematics Generic proforma model to estimate cost of electricity for various operating scenarios and plant design options Illustration of a possible cycle in which a solar field supplies steam to a natural gas combined cycle plant (Source: Abengoa) Value: Avoid fuel costs Reduce emissions Participate in renewable energy credit markets Meet renewable energy goals Supplemental project notice available next week Webcast will be held June 27 to get feedback 10

11 Continuing Supplemental Projects STEP Improved model for techno-economic evaluation of CSP HEPV Third Generation - Very High-Efficiency Solar Cells Study 11

12 Other Project Ideas Integration of central PV: incremental regulation needed and the corresponding effects on operation and emissions of other plants Thermal energy storage Grid integration vs. PV DC Integration of wind and solar 12
