AI summary

Cybersecurity incident impacts (permanent data loss): NS Power confirmed it has permanently lost time and date information for 2024 CNMP Participant Agreements due to the cybersecurity incident (NSEB IR-2), making it impossible to recalculate 2024 average service levels; the incident also caused delays in bi-directional meter configuration (OTA restoration forecast by end of Q2) and loss of hosting capacity map functionality, with GIS service restoration targeted for May 31, 2026 and first updated map publication targeted for June 26, 2026 (NSEB IR-5).
Regulation 3.6 review — no timeline or draft: NS Power confirmed it has not finalized or prepared any working draft amendments to Regulation 3.6 (governing net metering cost allocation) and declined to provide a specific filing timeline, stating it is conducting a comprehensive review of all Board-approved Regulations as an integrated framework rather than a targeted amendment; distribution network upgrade costs continue to be borne by interconnection customers under the cost-causer approach in the SSGIA, with no utility recovery occurring (IG IR-1).
2025 CNMP program costs — modest and largely participant-borne: Incremental administrative and operational costs of the CNMP totalled approximately $3,800 in 2025, with $0 in distribution network upgrade costs as no upgrades were required for any Class 2 interconnection; Class 2 interconnection process costs paid by customers totalled approximately $40,200; none of these costs were transferred to non-participating ratepayers (IG IR-3).
Cost-benefit analysis of CNMP energy flows — net cost to system identified: NS Power's avoided cost analysis (NSEB IR-6) estimated that in 2025 the avoided cost of CNMP solar generation exported to the grid was approximately $244,000, while the incremental cost of providing energy offset by bill credits was approximately $475,000 — a net cost to the system of approximately $231,000 — with the avoided cost of behind-the-meter displacement estimated at an additional $374,000.
Service standard compliance and virtual inspection pilot: NS Power met four of six Class 1 service standards in 2025; three outlier accounts required 50–120 business days to execute Participant Agreements due to the cybersecurity incident, with no additional system or customer costs resulting (CA IR-3, NSEB IR-3); a virtual electrical inspection pilot involving approximately 30 contractors is in its third and final phase, with full implementation targeted for Q3 2026 (NSEB IR-1).
