EfficiencyOne notifies NSERB that NS Power cybersecurity incident has forced suspension of Residential Behaviour Program, materially threatening 2025 DSM targets
AI summary
- Efficiencyone (E1) informed Board Chair Stephen Mcgrath on August 21, 2025 that it has suspended its Demand Side Management Residential Behaviour Program due to Cybersecurity disruptions at Ns Power that have cut off the AMI customer consumption data feed required to generate customer reports and measure program savings (Exhibit 99090, p. 1).
- E1 last issued customer reports and tracked program savings in May 2025; without NS Power AMI data, E1 cannot measure usage differences between treatment and control group customers, rendering savings measurement impossible (Exhibit 99090, p. 1).
- No confirmed timeline exists for restoration of NS Power's data feeds; E1 characterizes the uncertainty and elapsed time as anticipated to "materially impact" its ability to achieve 2025 program component targets (Exhibit 99090, p. 1).
- E1 has suspended all discretionary costs associated with the program during the outage period and is coordinating with its program delivery partner on resumption protocols once AMI data becomes available (Exhibit 99090, p. 2).
- The NSERB acknowledged receipt of E1's letter on August 26, 2025, confirming the Board's awareness of the program suspension and its implications for 2025 targets, with no confirmed restoration timeline (Exhibit 99095).
