other way to say this is that for most months the effect size (average kWh savings per household) is extremely small, and the number of observations is not large enough to detect it.[49](#page-57-0) The data quality rule used for use of th...
AI summary The analysis highlights challenges in evaluating energy savings from programs like ARet and SEM, noting extremely small effect sizes (average kWh savings per household) and data quality rules that undercount savings by assigning zero to most months. Yearly analysis using average daily savings appears to validate cumulative savings but relies on statistically insignificant daily savings. Large sample sizes can falsely inflate significance of trivial effects.
two large sites produced 364% of the total tracked energy savings for all compressed air audit measures in 2023, even though these programs were implemented at these same locations during that period. In 2024 savings associated with compre...
AI summary In 2023, two sites contributed 364% of total compressed air audit savings. In 2024, compressed air leak audits surpassed combined savings from motors, solar PV, and HVAC retrofits. The Pay-for-Performance program, added in 2023, saw 22 new participants in 2024, with savings delayed until 2025. Retrofit projects included refrigeration, motors, and HVAC, with limited building envelope savings.

2.6 BENCHMARKING STUDY
AI summary The document section titled '2.6 BENCHMARKING STUDY' outlines a regulatory proceeding involving a benchmarking study. Key entities include Nova Scotia Power Inc. (NSP) and the Nova Scotia Energy Board (NSEB), with acronyms such as BCA and TRC referenced. The study likely evaluates efficiency metrics and resource costs.
Synapse Synapse states: …I also recommend that NSEB direct E1 to conduct its own benchmarking study to inform the development of its cost-effective demand response offering for its 2027-2031 DSM Plan and to leverage Efficiency Canada's for...
AI summary Synapse recommends that the Nova Scotia Energy Board (NSEB) direct EfficiencyOne (E1) to conduct a benchmarking study for its 2027-2031 Demand Side Management (DSM) Plan, leveraging Efficiency Canada's upcoming research to inform cost-effective demand response strategies.
E1 Response E1 acknowledges that conducting a benchmarking study could provide useful information for developing its demand response offerings. Although benchmarking studies are helpful in DSM planning, E1 cautions that benchmarking studie...
AI summary E1 acknowledges the value of benchmarking studies for DSM planning but cautions that jurisdictional differences may limit their applicability. They argue there is insufficient time to conduct a separate study if the Efficiency Canada benchmarking study is not released promptly. E1 commits to using Efficiency Canada's findings if available and to conducting a jurisdictional scan and literature reviews for the 2027-2031 DSM Plan.
3. Effect Size The Peach Report states as follows in relation to effect size at the household level:[14](#page-25-1) Due to the effect size at the household level, a savings claim for the program does not make sense. Similarly, unless NSP...
AI summary The Peach Report argues that savings claims for the program at both household and system levels lack validity due to effect size, noting a 6.27 GWh system-level effect. It states such claims are invalid unless NSP demonstrates otherwise.
- In energy behaviour programs, the primary goal is to achieve energy savings at the population level, through the change of individual behaviours. Unlike behavioural interventions in health care, where the focus is often on improving indi...
AI summary Energy behaviour programs aim to reduce population-level energy consumption through behavioral changes, differing from healthcare interventions that focus on individual outcomes. Causal mechanisms in energy efficiency have been studied for 20 years, with interventions like Home Energy Reports demonstrating effectiveness through observed outcomes, even without full understanding of individual behavior pathways.
1. Protocol Issue The Peach Report states as follows in relation to the measurement & verification (M&V) protocol for compressed air leak projects: [31](#page-40-0) […] The Uniform Methods Protocol, provided by the U.S. Department of Energ...
AI summary The Peach Report discusses the M&V protocol for compressed air leak projects, noting that ultrasonic leak detectors are ineffective for quantifying leakage rates due to their reliance on sound correlation rather than direct measurement. The protocol recommends standardized leak-down tests before and after repairs for accurate measurement.
le. Of those jurisdictions, none require that leak-down tests be performed by participants to support savings. A more detailed breakdown of M&V requirements for these jurisdictions is presented below. - › Three jurisdictions[32](#page-42-0...
AI summary The text outlines varying approaches to measurement and verification (M&V) requirements for compressed air leak projects across jurisdictions. Three use ultrasonic devices, three use a leak orifice diameter-to-leak rate table, and one requires SEM program compliance with IPMVP Option C for full-facility data.
2. Chain of Events The Peach Report states as follows in relation to the chain of events surrounding the two compressed air leak projects being discussed: [37](#page-43-0) The result of this methodology produces estimates that are unverifi...
AI summary The Peach Report criticizes the methodology for compressed air leak projects, arguing that it produces unverifiable estimates. The approach uses a non-UMP protocol-compliant device to assess leaks, leading to no records of leaks post-repair and inability to verify repair effectiveness.

AI summary EfficiencyOne applied for approval of the 2026 DSM Extension and amendment to its 2023-2025 DSM Purchase Agreement with Nova Scotia Power Inc. The Board approved the performance targets, amendments, and directed development of a 2027-2031 DSM Plan.
4.4 Synapse [37] Synapse stated that the 2026 DSM extension of energy efficiency initiatives remains cost-effective at the portfolio level. It stated: "The first-year cost of saved energy falls in the middle of the Canadian and leading U.S...
AI summary Synapse supports approving the 2026 DSM Extension's energy efficiency and demand response components but recommends specific conditions for the 2027-2031 plan, including a PAC test value ≥1.0, independent benchmarking studies, targeting constrained areas, and incorporating avoided transmission costs. It also urges E1 to leverage Efficiency Canada's research.
5.9 Performance Requirements [81] For the 2026 DSM Extension, E1 proposes to use the same definitions of performance metrics, targets, performance indicators, and thresholds as in the approved 2023-2025 Plan. E1 proposes that its performan...
AI summary E1 proposes extending DSM performance metrics from 2023-2025 to 2026, including targets like 528.7 GWh energy savings, 97.7 MW peak demand reduction, and 16.3 MW winter demand response. E1 also seeks to include low-income programs and estimates a $236.8M investment over four years.
5.10.1 Findings [89] Since the Board did not approve E1's proposed benefit-cost analysis test in its recent decision and directed E1 to use the PAC test (2025 NSEB 18), the Board finds it is appropriate to limit the requested reporting to...
AI summary The Board directed E1 to use the PAC test for cost-effectiveness analysis instead of its proposed method, requiring PAC test results for 2023-2025 and future annual reports. This avoids consultant costs and ensures sufficient data for evaluating program administrator performance.
6.0 CONCLUSION AND SUMMARY OF BOARD FINDINGS [90] The Board approves E1's proposed performance targets for the 2026 DSM year and the amendments to its 2023-2025 DSM Supply Agreement with NS Power to incorporate the legislative changes and...
AI summary The Board approves E1's 2026 DSM performance targets and amends its agreement with NS Power. Directives include engaging with DSMAG, addressing program concerns, including PAC test results, and handling cybersecurity impacts. E1 must address demand response program concerns and revise mid-course adjustment processes in its upcoming DSM Plan.
