EfficiencyOne filed its Q3 2025 DSM Report showing 105.7 GWh of year-to-date energy savings but a significant shortfall in demand response capacity attributed in part to NS Power's cybersecurity incident
AI summary
- Efficiencyone reported Q3 2025 net incremental energy savings of 26.3 GWh and year-to-date savings of 105.7 GWh against a 2025 Plan as Approved target of 149.5 GWh, with a year-end forecast of 131.8 GWh — an 11.8% shortfall (Table 2, p. 6).
- The Demand Side Management Demand Response program is expected to achieve only 6.9 MW of available capacity for the 2024/25 season, a 38% achievement rate against the 17.9 MW three-year Plan Performance Target, with NS Power AMI data unavailability and participant opt-outs cited as contributing factors (Table 1, p. 3; Section 6, p. 22).
- The Residential Behaviour program component remains indefinitely paused after NS Power's Cybersecurity incident disrupted AMI data feeds; the program had represented approximately half of Existing Residential's 2025 energy savings target, driving the residential unit cost forecast from \$0.41/kWh to \$0.52/kWh (Table 4, p. 11; Section 4.2, p. 18).
- Low Income Programs targeted at Affordable Single-family Homes, Affordable Multi-family Housing, and the Mi'kmaw Home Energy Efficiency Project are on track to meet the 15.8 GWh three-year Performance Target at 99% cumulative achievement, with Affordable Single-family Homes participation reaching 304% of its 2025 Plan as Approved target (Table 1, p. 3; Table 3, p. 9).
- Performance Monitoring Enabling Strategies expenditures are forecast at \$6.8 million versus a Plan as Approved of \$4.6 million, driven by regulatory costs for the 2026 DSM Extension application, the upcoming 2027-2031 DSM Plan development, and a benefit-cost analysis application hearing held September 22–23, 2025 (Table 13, p. 28; Section 9, p. 28).
