AI summary The Board has raised concerns with NSPI's approach to assessing the reliability impacts of individual projects, as it relies on asset risk profiles rather than directly evaluating reliability outcomes. The Board also expressed dissatisfaction with NSPI's lack of urgency in meeting reliability targets, particularly regarding the Five-Year Reliability Plan and its ability to achieve a 20% improvement in SAIDI by 2029.

Planned Outages and Reporting Transparency While NSPI has met its adverse weather response standards, planned outages remain a material source of interruption for customers. Industrial customers must curtail production, change schedules an...

AI summary The document discusses concerns raised by the Industrial Group regarding the increasing number of planned outages by NSPI and the lack of detailed reporting on their impact. While NSPI provides aggregate data, the Industrial Group argues that disaggregated data by feeder or substation would better inform the Board about the distribution and impact of planned outages on customers.

Conclusion In summary, the Industrial Group respectfully submits that: - 1. NSPI should file in its Annual Performance Standards Report, a program-level attribution analysis identifying the SAIDI improvement estimated to result from each c...

AI summary The Industrial Group submits several recommendations to NSPI and the Board regarding performance standards, including the need for detailed reporting on SAIDI improvements, transmission loss of supply analysis, and the inclusion of customer-level metrics in performance standards. They also suggest penalties under the PUA be credited to the FAM for customer benefit.

AI summary Nova Scotia Power's 2025 Annual Performance Standards Report highlights progress in reducing outage frequency and duration under its Five Year Reliability Plan. However, it failed to meet customer service targets due to a 2025 cyber attack, which impacted call answer rates and estimated bill percentages. The report also notes apparent improvements from vegetation management and tree trimming efforts.

AI summary The Industrial Group (IG) acknowledges NS Power's 2025 reliability improvements but criticizes the lack of a quantitative model to attribute these improvements to specific Reliability Plan programs. The IG requests the Board to direct NSPI to provide a program-level attribution analysis and trajectory analysis in its next Annual Performance Standards Report to ensure proper efforts are being made for anticipated inclement weather.

AI summary The Industrial Group argues that the presentation of planned outage data in aggregate form prevents the Board from assessing how planned outages impact customers and locations across the system. They recommend disaggregating the data by feeder or substation groupings in future Annual Performance Standards Reports to better identify patterns and distribution.
