H. Gil Peach & Associates files 2024 Savings Verification Review of Efficiency Nova Scotia DSM programs, recommending rejection of savings claims for four program areas while accepting the broader portfolio
AI summary
- The Savings Verification Review (Exhibit E-2), prepared by H. Gil Peach & Associates LLC for the Nova Scotia Energy Board, verifies 2024 electricity savings and demand reduction across Efficiency Nova Scotia's full Demand Side Management portfolio, finding Econoler's independent evaluations generally meet standards of independence, transparency, and protocol compliance (pp. 7–8).
- The portfolio achieved evaluated net peak demand reduction of 30.69 MW plus 8.091 MW in available Load Management demand response capacity at the generator, with 172.76 GWh in first-year net energy savings and 2,430.56 GWh in lifetime net savings; Residential Programs contributed ~55% of demand reduction and Commercial Industrial Programs contributed ~55% of first-year energy savings (Tables 1–2, pp. 8–10).
- The report recommends rejection of evaluated savings for four areas: (1) compressed air leak detection under the BNI Custom Incentives program, where the evaluator did not follow the Uniform Methods Protocol for independent measurement (pp. 62–66); (2) the Residential Behaviour ('Efficiency Insights') program (6.27 GWh), where household-level effect sizes are too small to be of practical significance despite statistical significance driven by a very large sample (~239,000 treatment households) (pp. 44–57).
- The two Demand Response programs (Residential DR at 0.057 MW; BNI DR at 8.034 MW) are also flagged as producing demand reductions too small to demonstrate practical utility system value, with the report recommending that evaluators shift from statistical to practical significance criteria and provide explicit business-case justifications for such programs (pp. 69–71, SVR24-G-1, SVR2024-Demand Response-13).
- The Mi'kmaw Home Energy Efficiency Program (Indigenous Communities) received a positive evaluation finding — described as 'excellent' — with 192 participants in 2024 (the highest since program inception), though average savings per participant fell 41% due to revised adjustment ratios; the report also flags the Low Income Programs Affordable Single-Family Homes program as exceeding its net energy savings target by 32% and demand target by 100% (pp. 30–38).
