1 LRS Report to PCC Wally Gibson, NWPCC Planning Coordination Committee Albuquerque, NM March 6-7, 2008

2 2 PSA Status – 1 Generally same approach as last year Keeping same building block but updating calculations Contingency reserves Regulating reserves Additional forced outage reserves Reserve for 1-in-10 weather driven load Addressing additional issues with scenarios Unpredictable plant retirements (California cooling water) Other ways of displaying extreme weather problems Initial look at energy constraints outside NW Wind capacity contribution

3 March 6-7, PSA Status – 2 Breaking out planned resource classes further 2007 PSA: Class 1: Under construction, in service Jan 2011 Class 2: Active regulatory review, in service by Jan PSA Class 1: Under construction, in service Jan 2012 Class 2: All permits approved and interconnection agreements signed and in service Jan 2014 Class 3: Under regulatory review and facility study done with active negotiation of interconnection agreement and in service Jan 2014

4 March 6-7, NERC Adequacy Reports Long-Term Reliability Assessment (LTRA) NERC asking for more detail on status of future resources and on demand side and energy efficiency programs Additional data requests – a likely future pattern LTRA Scenario New emphasis for NERC – a big issue for them 2009 Scenario: Accelerated renewable integration – Additional 15% total energy from renewables by 2018 Study plan to NERC PC this June, report in spring 2009 Expect to build off a 2017 TEPPC case Issue: Respond by the book or with realistic answers

5 March 6-7, Future Work Following NERC developments and working with Western participants on NERC resource adequacy-related task forces and subcommittees Expect additional data requests for NERC studies Expand analysis of energy constraints Evaluating future use of Promod for adequacy assessments Continuing to work with TEPPC on getting most efficient data gathering process
