EfficiencyOne filed undertaking response comparing PAC test, modified BCA test, and proposed BCA test ratios for heat pump replacement scenarios in M12282
AI summary
- Energy Futures Group (EFG) responded to Undertaking U-1, providing benefit-cost ratio results using the Program Administrator Cost (PAC) test and a modified version of EfficiencyOne's proposed Bca test with host customer impacts excluded (Exhibit E-34, filed October 1, 2025).
- Under the PAC test, heat pump replacements of electric resistance systems yield a benefit-cost ratio of 4.95, while fuel oil and natural gas replacements score 0.00 due to the absence of utility system benefits on the benefits side (Table 1).
- Removing host customer impacts from the proposed BCA test (modified BCA) raises ratios relative to the full proposed BCA: electric resistance increases from 4.17 to 7.93, fuel oil from 1.80 to 2.10, and natural gas from 0.45 to 0.50, because host customer costs exceed host customer non-energy benefits in the illustrative 1,000-unit example.
- The comparison across all three tests (proposed BCA, modified BCA, and PAC) is summarized in Table 1 of the undertaking response, drawing on Dr. Hill's direct testimony in Appendix A of Exhibit E-1 (pages 13–14) as the baseline illustrative analysis.
