AI summary Energy and demand savings in 2023–2024 exceeded approved targets due to the Canada Greener Homes Grant and LED rebate campaigns. Savings declined in 2025 due to baseline changes and program closures. The 2026 DSM Extension expects lower savings, driven by non-lighting measures and reduced Home Energy Assessment participation.
2.2.3 PROGRAM ADJUSTMENTS In 2025, E1 ended two program components - Green Heat and Appliance Retirement. Green Heat continued to experience a steady decline in participation and energy savings in 2025, consistent with trends observed in 2...
AI summary E1 ended two programs in 2025: Green Heat and Appliance Retirement. Green Heat's decline was due to the Canada Greener Homes Grant and reduced savings from DSM evaluations. Appliance Retirement closed due to rising costs, declining savings from newer units, and limited service providers. Deadlines were December 31, 2025 for Green Heat and January 8, 2025 for Appliance Retirement.
Energy Efficiency The investment for energy efficiency is reflective of the costs E1 expects to incur to achieve the savings with the suite of programs included in the Preferred Plan. Investment levels in Residential sector programs repres...
AI summary E1's energy efficiency investment allocates 56% to residential programs (29% savings) and 44% to BNI programs (71% savings), reflecting a shift toward non-lighting measures post-2025 LED baseline. Savings decline from 2027-2031 due to Canada Greener Homes Grant closure and removal of Residential Behaviour. 2024 billing analyses further reduced residential savings.

2025 and overall 2023-2025 spending being within the approved $173.0 million investment level; but also contributed to energy savings and demands savings coming in lower than the 2025 Plan targets. Demand savings for both E1's Residential...
AI summary The 2025 Plan's energy and demand savings fell below targets due to factors like NS Power's cybersecurity incident, program adjustments (e.g., LED measures removal), federal grant closures, and declining program efficacy. Residential Behaviour's energy savings dropped significantly, impacting overall results. Green Heat and Appliance Retirement programs ended due to sustained low savings.
Green Heat Highlights - Green Heat continued to experience a steady decline in participation and energy savings in 2025, consistent with the trend seen in 2023 and 2024. This trend precipitated the decision by E1 to close the program compo...
AI summary Green Heat program participation and energy savings declined steadily from 2023 to 2025, leading E1 to close the program by December 2025. Factors included competition from the federal Canada Greener Homes Grant and evaluation findings showing reduced savings from key measures. Biomass and other measures were removed in May 2025 due to low uptake and minimal savings.
Home Energy Assessment Highlights - Home Energy Assessment exceeded its 2025 Plan as Approved energy and demand savings targets, but results declined from 2023 and 2024 levels, as expected, following the Canada Greener Homes Grant (which E...
AI summary The Home Energy Assessment program met 2025 energy and demand savings targets but saw declining results post-2023 due to the Canada Greener Homes Grant closing in Q1 2024. Remaining grant participants must complete assessments by November 2025, with rebate processing expected by March 2026. The program was integrated into E1's Customer Information System in 2025, with process improvements ongoing.

HEA Findings and Recommendations This subsection presents the key findings from the 2025 HEA evaluation. The Evaluator has no specific recommendation for HEA. 2025 HEA-Finding: HEA net electrical energy savings exceeded the 8.580 GWh targe...
AI summary The 2025 HEA exceeded energy savings targets by 61% and peak demand savings by 6%, but participation dropped significantly due to the closure of the Canada Greener Homes Grant. Realization rates reached 100% for both energy and peak demand savings, aligning evaluated results with E1 tracking.
17.1 HEA Description HEA is a home energy evaluation-based program component that encourages homeowners to improve the energy efficiency and comfort of their homes by providing them with related information and financial incentives in the...
AI summary The Home Energy Assessment (HEA) program in Nova Scotia encourages energy efficiency improvements through evaluations and rebates, administered with Natural Resources Canada (NRCan). It includes pre- and post-retrofit assessments, rebates for eligible upgrades, and collaboration with EfficiencyOne (E1). The Canada Greener Homes (CGH) Grant, co-delivered via HEA until 2025, provided up to $5,000 for retrofits but closed to new applications in 2024. The program aimed for 8.580 GWh in electrical savings and 4.325 MW in peak demand reduction by 2025.
Reporting Requirements HEA incentives originate from three sources of funding: Nova Scotia Power ratepayers for DSM, the Province of Nova Scotia, and the Government of Canada (CGH Grant). The inclusion of the CGH Grant as a co-funder of en...
AI summary HEA incentives are funded by Nova Scotia Power ratepayers (DSM), the Province of Nova Scotia, and the Canada Greener Homes Grant (CGH). Savings are reported to NSEB via DSM evaluations and the Province via government-funded reports. DSM focuses on electrical savings, while government reports emphasize participation and GHG reductions. Equations in Appendix XI address double-counting, and solar PV savings are included in DSM reports regardless of heating source.
