EfficiencyOne filed its 2024 DSM Annual Progress Report and Evaluation Reports, reporting 121% of its mid-course energy savings target but forecasting a shortfall on its demand response capacity performance target
AI summary
- Efficiencyone achieved 172.8 GWh of incremental annual net energy savings (121% of the 142.6 GWh mid-course adjusted target) and 30.7 MW of net peak demand savings (119% of target) in 2024, with total expenditures of $65.7 million — $8.2 million above the 2024 Plan as Approved spending level of $57.5 million (APR, pp. 3–4)
- For the three-year 2023–2025 Plan period, Efficiencyone forecasts achieving the 90% compliance threshold for energy savings (105% of target), demand savings (96%), and low-income energy savings (90%), but projects only 56% attainment of its 17.9 MW demand response available capacity target due to participant withdrawals, quality-related controller removals, and lower-than-expected adoption of battery devices (APR, Table 4, p. 14)
- Demand Side Management overperformance in the Residential sector was driven by the Instant Savings program component, where LED lighting rebates increased to 70–80% off during spring and fall 2024 campaigns — representing the final year for rebates on those products before baseline changes — resulting in energy savings double the 2023 levels (APR, pp. 4, 22–23)
- Low Income Programs met aggregate 2024 mid-course targets at 5.3 GWh through the combined performance of Affordable Single-family Homes (HomeWarming), Affordable Multi-family Housing, and the Mi'kmaw Home Energy Efficiency Project; however, a billing analysis updating the HOT2000 modelling software overestimation ratio reduced per-home savings, partially offset by significantly higher participation in Affordable Single-family Homes (1,193 homes vs. a target of 695) (APR, pp. 37–38)
- Program Evaluation activities filed concurrently include comprehensive impact evaluations for 11 program components, market evaluations for Efficient Product Installation and BNI Instant Rebates, and process evaluations for Affordable Multi-family Housing, Affordable Single-family Homes, BNI Instant Rebates, and Custom New Construction, with multiple 2023 evaluation recommendations now marked complete (APR, pp. 19–21; Attachment 2)
