Presentation Transcript

  1. Applying 2008 DEER 09-11 Planning Values to the 2002 Secret Surplus Study 18 May 2009 Peter Lai, CPUC Energy Division

  2. Objectives of Analysis • Estimate how the 2008 DEER 09-11 planning values would impact the results of the 2002 Secret Surplus Study (02 SSS) • key work paper for the 2004 adopted goals • focus adjustments on gross for lighting (all CFLs and linear fluorescents), NTG for all • Estimate both the gross and net values for the study when adjusted for 2008 DEER • 02 SSS reported 10 year net electric potential

  3. Estimation Process Undertaken • Use 02 SSS statewide gross measure annual results for each of ten years • Add adjustment factors for DEER value differences from underlying values: • kWh, kW, negative therms ratios for main lighting measures (CFL and linear fluorescents) • NTG values for all measures in DEER • Develop new annual gross and net values for each of the ten years • Aggregate the adjusted annual net and gross values by measure group and sector • Reduce to IOU portions of statewide values
