LRS Report to PCC Wally Gibson, NWPCC Planning Coordination Committee Spokane, WA June 26-27, 2008
PSA Status - 1 • Will post draft for earlier review this year • 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 temperature issues with scenarios • Unpredictable plant retirements (California cooling water) • Goal: Phase out once-through cooling, ~20,000 MW • Implementation schedule, details, effects unknown • Narrative on magnitude and issues, no full scenario
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 2013 • 2008 PSA • Class 1: Under construction, in service Jan 2012 • Class 2: All permits approved and interconnection agreements signed and in service Jan 2014 -- small class • Class 3: Under regulatory review and facility study done with active negotiation of interconnection agreement and in service Jan 2014
NERC Adequacy Reports • Long-Term Reliability Assessment (LTRA) • NERC asking for more detail on status of future resources, demand side and energy efficiency programs • Additional data requests – a likely future pattern • LTRA Scenarios • New emphasis for NERC – a big issue for them • 2009 Scenario: Accelerated renewable integration – 15% total energy from renewables by 2018 • Build off TEPPC 2017 WIRAB case (20% CO2 reduction from 2005 levels) • Bring in results of other studies (e.g., CAISO, WWSIS) • Study plan approved by NERC PC, report due spring 2009
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
