4 CREPC History Underlying premise –There is a need for all state and provincial agencies in the Western Interconnection to share information on electric power issues Organization –Joint committee of WIEB and WCPSC –WIEB provides staff support Evolution –Formation in 1983 –1983-mid 90s – information sharing and learning –Mid 90s-2005 – information sharing + participation in Western industry institutions + responding to requests from WGA + interaction with FERC and DOE Counterparts in other regions –Organization of MISO States – PUCs only? –New England – NECPUC – PUCs –Organization of PJM States – PUCs –SPP Regional State Committee – PUCs

8 CREPC Priorities Past priorities –Information sharing –Learning about the western grid Current priorities and Governors’ requests –Resource adequacy assessment – Grace Anderson –Reliability – Bill Chamberlain –Transmission expansion Pro-active planning – Doug Larson Cost allocation/cost recovery – Carl Linvill –Market assessment/monitoring – LouAnn Westerfield(?) –Other – Doug Larson Analysis of actual flows and ATC WGA Transmission Permitting Protocol Western Renewable Energy Generation Information System (WREGIS)

9 Resource Adequacy Grace Anderson

10 Reliability Bill Chamberlain

11 Transmission Planning History –Crash effort in 2001 –SSG-WI interconnection-wide planning –Sub-regional transmission planning taking hold Some (STEP, NTAC and SWAT-maybe have institutional homes) RMATS does not have an institutional home –Key issues Planning done with public, transparent database Process open to all stakeholders Link transmission planning to IRPs –CREPC agreed to ask companies to compare IRP forecasts and forecasts submitted to WECC Identify who benefits (helpful in cost allocation/recovery decisions)

12 RMATS Interconnection-wide planning by SSG-WI NTAC STEP SWATCommittee (CATS +) NV state study for wind underway CA state studies underway NM transmission study underway Western Interconnection Transmission Planning

13 Cost Allocation/Recovery Carl Linvill

14 Other CREPC Topics Analysis of actual flows and ATC WGA Transmission Permitting Protocol Western Renewable Energy Generation Information System (WREGIS) WIEB/CEC natural gas assessment
