ACKNOWLEDGMENTS The PIER Research Manager for this project was Virgil Rose. A Technical Advisory Committee (TAC) was established to review research results and offer guidance to the research team. Two in-person TAC meetings were held along with other written and oral communications as needed and appropriate. The Technical Advisory Committee consisted of: o Dede Hapner, Vice President, FERC and ISO Relations, Pacific Gas & Electric. o Les Starck, Director of T & D Business Unit, Southern California Edison. o Caroline Winn, Director of T&D Asset Management, San Diego Gas & Electric. o Sean Gallagher, Director of Energy Division, California Public Utilities Commission. o Steve Ellenbecker, Energy Advisor to Wyoming Governor Freudenthal. o Jim Bushnell, Research Director, UC Energy Institute. The research team and key areas of research responsibilities were as follows: o Project Management and Outreach – Joe Eto and Vikram Budhraja. o Review of Technologies – John Ballance, Jim Dyer, and Jim Terpening. o Industry and Regulatory Changes – Vikram Budhraja, John Ballance and Jim Dyer. o Review of other Regions and Industries – Alison Silverstein. o CA ISO Transmission Planning Process and Comparison of ISO’s -- John Ballance and Jim Dyer. o Benefit Quantification, Cost Allocation, Cost Recovery – Vikram Budhraja and Fereidoun (Fred) Mobasheri. The research team wishes to thank the Virgil Rose, PIER Project Manager for his guidance, support and encouragement throughout the project and the TAC members for their useful insights to sharpen the research focus.

California Energy Commission, PIER Energy-Related Environmental Research Program. CEC-xxx-xxxx-xxx Preface The Public Interest Energy Research (PIER) Program supports public interest energy research and development that will help improve the quality of life in California by binging environmentally safe, affordable, and reliable energy services and products to the marketplace. The PIER Program, managed by the California Energy Commission (Energy Commission), conducts public interest research, development, and demonstration (RD&D) projects to benefit California. The PIER Program strives to conduct the most promising public interest energy research by partnering with RD&D entities, including individuals, businesses, utilities, and public or private research institutions. PIER funding efforts are focused on the following RD&D program areas: Buildings End-Use Energy Efficiency Energy Innovations Small Grants Energy-Related Environmental Research Energy Systems Integration Environmentally Preferred Advanced Generation Industrial/Agricultural/Water End-Use Energy Efficiency Renewable Energy Technologies Transportation Benefit Quantification and Cost Allocation/Recovery Research Project for Transmission is the final report for the Cost Allocation Research project Contract Number 500-05-001, work authorization number MR0606/MR-051 conducted by Consortium for Electric Reliability Technology Solutions/Electric Power Group, LLC. The information from this project contributes to PIER’s Energy Systems Integration Program.
