Background

Commission Directives for the 2009 Bridge Funding Period

  • D. 08-10-027
    • 1-Year bridge funding period in 2009 for certain programs carried over from 2006-2008
    • Use 2005 DEER values to determine a baseline and 2008 DEER updates for reporting and evaluating performance in 2009
  • D. 10-04-029
    • Use results from 2006-2008 impact evaluation reports as primary inputs for calculating energy savings for 2009 bridge funding programs
    • Programs and measures continued from 2006-2008 were considered for updates
    • Programs and measures new for 2009 were passed through
    • Updates were for those eight specific parameters identified in the Performance Basis Protocol issued on January 11, 2006 ALJ Ruling

  • Prioritization
    • The parameters for measures included in the 2006-2008 study (virtually the same measure going by a different name) or were updated using the results from the 2006-2008 HIM Impact Evaluations.
    • DEER values were applied to EULs.
    • Pass thru values were applied where no better parameter update could be made.
  • Major differences between 2006-2008 ERT and 2009 ERT
    • High Bay occupancy sensors in SDGE’s programs were a major percentage of the program savings.
    • High Bay occupancy sensors were passed thru because they were not studied in the 2006-2008 program evaluation.
  • Lighting updates (by measure name, program and building type)
    • Delta watts (by measure name) X Hours of Operation (by program and building type) = Savings
    • New combinations of the measure name, program, and building type existed in 2009. The UES for the new combinations were calculated using the 2006-2008 results.

  • SBW Major Commercial Study (SBW_MC)
    • 8270 records across SCE2517, SCG3513, SDGE3010 and SDGE3025 updated with UES, NTGR and IRateresults
  • ADM Commercial Facilities HIM Study (ADM_ComFac)
    • In SCE2517, 3618 refrigeration records updated with UES and IRateresults and 4688 records updated with NTGR
  • ItronSmall Commercial HIM Study (Itron_SmCom)
    • 2372 lighting records in program SCE2517 updated with UES, NTGR and IRate results
  • Database for Energy Efficiency Resources (DEER)
    • 541 records in SCE2517 updated with NTGR and 8463 records in SCE2517 and SCG3513 updated with EUL..

  • Percent kWh and therms affected by updates

Commercial Retro-commissioning
  • SBW Retro-Commissioning Study (SBW_RCx)
    • 120 records among 8 PGE programs and 198 records among 2 SCE programs updated with UES and NTGR results
  • KEMA Non-Res New Construction Study (KEMA_NRNC)
    • 11 measures in PGE2006 NRNC updated with UES and NTGR results; 8 of those measures part of “Whole building – new construction” HIM
  • Database for Energy Efficiency Resources (DEER)
    • 309 PGE records and 1 SCE record updated with EUL values from DEER

  • Percent kWh and therms affected by updates

In all cases IRate was set to one. For measures receiving updates for UES and NTGR, all energy savings were accounted for in the UES values.

  • Updates were applied only to the same HIM measures contained within the same program (EDPrgID) as 2006-08.
  • Measure names were different in 2009 than 2006-08, but the measures were still associated with the proper EDMeasureGroup
  • 2006-08 Irate and NTG Parameters applied by Program
  • Within Programs the Climate Zone specific UES values were applied
  • No new data was collected and no new values were calculated
new construction codes and standards
New Construction/Codes and Standards
  • Non-Residential New Construction
    • Only the UES (unit energy savings) and NTGR (net-to-gross ratio) parameters were updated using 2006-08 evaluation results
  • Residential New Construction
    • Only the UES (unit energy savings) and NTGR (net-to-gross ratio) parameters for Whole House measures in the NCCS Residential New Construction (RNC) were updated
    • SDGE3007did not rebate any Whole House measures, so all ex-ante parameters were passed thru
    • Due to complications with the different databases and the small magnitude of savings it was determined that all values for PG&E 2009 would be passed through.

  • Tracking records were divided into three categories: pump-off controllers (POC), non-POC electric measures, and gas measures. Realization rates and net-to-gross ratios were derived for each category, by stratum.
  • Updated 2009 records for all programs using the RR and NTGR estimated in the 2006-2008 program cycle. The same measure categories and strata boundaries as in 2006-2008 were used for this purpose.
  • Exceptions 19 New Construction records, updated by the NCCS Contract Group; and 3 RCX records, updated by the RCX Contract Group. Both the NCCS and RCX Groups used 2006-2008 evaluation results to update their respective records.

  • SCE2509
    • In 2006-2008, SCE adjusted claims using a realization rate of .89
    • In 2009, SCE did not use the .89 adjustment
    • In order for the 2006-2008 realization rates to be applicable to the 2009 program year the following adjustments were made:
  • The 2009 records were updated using the adjusted RR and the NTGR estimated in the 2006-2008 program cycle. The same strata boundaries as in 2006-2008 were used for this purpose

  • SCE2510
    • Agricultural: The gross impacts for the 2009 records were passed through, as in the 2006-2008 evaluation. The 2009 tracking records were updated using the 2006-2008 NTGR estimates
    • For Pump Testing, SCE used a completely different set of impacts in 2009 as compared to 2006-2008, as reflected in the 2009 Workpapers
      • Since the 2009 impacts were different, the 2006-2008 results could not be used to update 2009 records for this program
      • The 2009 ex-ante impacts were passed through
pge agricultural
PGE Agricultural
  • PGE2001 project records were adjusted; other 3rd party program records were passed through.
  • Installation rates – assumed to be 100% as install rates were picked up in realization rates for the 06-08 evaluation.
  • Unit Energy Savings (UES)
    • Included savings: realization rates from the 06-08 evaluation were applied to gross savings from the tracking system.
    • Omitted savings (savings from a fuel that weren’t accounted for in tracking): per-unit savings from the 06-08 evaluation were applied to each record from the tracking system.
  • Interactive Effects - consistent with the 06-08 evaluation, no interactive effects were calculated
  • Net-to-gross ratios (NTGRs) – results from the 06-08 evaluation were utilized; NTGRs varied by kW, kWh, and therms.
  • Effective Useful Lives (EULs) – tracking system results were passed through.

      • New avoided cost tables
      • New load shapes consistent with DEER
      • Upstream Payments field added to the Export tab.
    • Replaced IOU claims table with 2009 claims table

      • Reference new 2009 IOU_E3 tables instead of 2008 tables.
      • Modified code to adjust quantities into Q42009  (year 2009 for SCE) where the paid date is after 12/31/2009.
      • Added Upstream Payments field to the comparison queries and Results_Savings_Claim table to capture Upstream Payments output from the E3s.
