Topic:"Performance Monitoring" in M12558

Scope of TOR Synapse will include the following topics in its assessment: - Review of NS Power's historical reliability performance standards and current SAIDI and SAIFI targets. - Review and summary of recent NS Power annual performance s...

AI summary Synapse will assess NS Power's reliability performance, including historical data, current targets, and community-specific reliability analysis. It will also evaluate NS Power's methodology for setting reliability goals, compare performance with other utilities, and assess the 5-year plan's effectiveness in meeting 2025 targets.

1 2 In 2025, NS Power's Performance Standards SAIDI (4.79) was the best result since 2020, and SAIFI (1.57) was the best result since 2012. The targeted investments undertaken in 2025, as well as those in recent years, contributed to these...

AI summary In 2025, NS Power achieved its best SAIDI and SAIFI results since 2020 and 2012, respectively, due to targeted investments. The SAIDI projections in Figure 28 are not meant to be exact annual reconciliations but provide a directional reference for performance improvement. The data used for the 20% improvement in SAIDI is referenced in IR-38 Attachment 2.

AI summary The table presents performance data for various feeders from 2019 to 2025, showing averages, standard deviations, and average plus two standard deviations for CKAIFI and CKAIDI metrics. The data reflects performance trends over time for different feeders.

- 11 1) Improve the customer reliability experience by reducing SAIDI by 20 percent from the 12 five-year average (2019-2023) of 5.10 and achieving the Performance Standards SAIFI 13 target of 2.05. - 15 2) Continue to strengthen grid resi...

AI summary The text outlines goals to improve customer reliability by reducing SAIDI and achieving SAIFI targets, as well as enhancing grid resilience to climate change. These efforts aim to ensure faster service restoration after major weather events, with some positive results already observed.

(b) Cost-effectiveness was evaluated primarily at the program and asset-class level through NS Power's capital governance and asset management processes, supported by program-level reliability forecasting and comparative assessment of alte...

AI summary NS Power evaluated cost-effectiveness at the program and asset-class level, considering capital expenditures and reliability benefits such as reduced outage duration and frequency. Feeder-level data was used to prioritize investments, but not for standalone cost-benefit analyses at the feeder level.

(f) Please describe how grid modernization interacts with the other categories of investment proposed in the reliability plan. For example, will increased automation and monitoring of grid conditions allow the Company to more effectively c...

AI summary The response outlines a five-year, $78 million investment plan for the Advanced Grid Modernization Program, aiming to reduce SAIDI by 20% through a risk-based approach. The plan considers historical data and operational constraints, with projections based on total investment rather than individual projects.

RTU Connectivity Substation Description Substation Criticality Substation Customers Feeder Criticality 22 performance and customer experience at the feeder level. In alignment with NS Power's 23 Performance Standards reporting, CKAIFI and...

AI summary The document presents data on substation and feeder performance metrics, including CKAIFI and CKAIDI, for various years and feeders. It aligns with NS Power's performance standards and includes metrics with major events and planned outages removed.

CONFIDENTIAL (Attachment Only) 1 Request IR-76: 2 3 Please refer to NS Power's response to IR-21 which states, "Electricity Canada's 4 methodology for calculating performance metrics does not account for behind-the-meter 5 generation or ot...

AI summary The response to IR-76 discusses Electricity Canada's methodology for calculating performance metrics, specifically how interruptions are defined as the loss of service to a metered service, and clarifies that behind-the-meter generation or backup power does not mitigate interruptions for reporting purposes.

NON-CONFIDENTIAL 1 (b) A problem feeder is defined by the Performance Standards as a feeder that has been among 2 the worst 5 percent of all NS Power's circuits with respect to either CKAIFI or CKAIFI 3 respectively for two consecutive yea...

AI summary The document defines a 'problem feeder' based on performance standards, using metrics like CKAIFI. It explains how factors such as maintenance access and communication influence a feeder's criticality rating, with specific scoring examples provided.

15 (d) As previously discussed in IR-7, NS Power does not assess reliability by specific customer 16 classes or customer types. Reliability is tracked on both a system-wide basis and on an 17 individual feeder basis regardless of the break...

AI summary NS Power does not assess reliability by specific customer classes or types. Reliability is tracked system-wide and on an individual feeder basis, and reliability improvements are not projected by rate class in the Five-Year Reliability Plan, consistent with the calculation of Performance Standards SAIFI and SAIDI.

Request IR-76: - Please refer to NS Power's response to IR-21 which states, "Electricity Canada's methodology - for calculating performance metrics does not account for behind-the-meter generation or other - sources of backup power." Pleas...

AI summary The document requests documentation related to Electricity Canada's methodology for calculating performance metrics, noting that it does not account for behind-the-meter generation or other backup power sources, as stated in NS Power's response to IR-21.
