H. Gil Peach & Associates filed a 2024 Savings Verification Report recommending acceptance of most EfficiencyOne DSM evaluation results, while flagging four programs—compressed air Custom incentives, Residential Behaviour, and both Demand Response programs—for insufficient or unverified savings.

AI summary

The verifier (H. Gil Peach & Associates) recommends accepting Econoler's 2024 evaluated portfolio results of 30.69 MW net peak demand reduction and 172.76 GWh first-year net energy savings at the generator, with exceptions for four programs (SVR24-G-1).
The BNI Custom Incentive Program compressed air leak audit component is flagged for non-compliance with the Program Evaluation Uniform Methods Project protocol: the evaluator used ultrasonic leak detectors for quantification rather than required leak-down tests, two dominant sites produced anomalously escalating savings (a 522% year-over-year increase), and proprietary data restrictions prevented independent verification; the verifier recommends savings from these projects not be accepted (SVR2024-Compressed Air–10 through 12).
The new Residential Behaviour "Efficiency Insights" program (Econoler-evaluated at 6.27 GWh, no demand reduction) is found to produce per-household savings of only 0.06–0.14 kWh/day (<1% of daily use), and aggregate savings representing ~0.06% of the Nova Scotia Power system requirement; the verifier recommends the program be reclassified as a marketing and promotional tool rather than a direct energy-savings program (SVR2024-Behaviour-5).
Both Demand Response Load Control programs—Residential DR (0.057 MW, Mysa thermostats only) and BNI DR (8.034 MW)—are found to have demonstrated insufficient practical demand reduction value; the verifier recommends future evaluations provide a business case for each program's bottom-line utility system benefit (SVR2024-Demand Response–13).
Ten programs received no evaluation issues, including Home 4 Energy Assessment (HEA, 31.96 GWh, 8.68 MW—highest demand reduction in portfolio, driven significantly by solar PV under the Canada Greener Homes Grant), Mikmaw Home Energy Efficiency Project Mheep, Affordable Multifamily Housing And Non Profit Organizations Amf, and BNI Efficient Product Rebates Program, with the verifier conducting 93 site visit inspections across the portfolio.
