AI summary The document states that Advanced Metering Infrastructure (AMI), also known as smart meters, is the standard service for NS Power customers, with AMI data used to determine customer billing.

tion rates for Point Aconi, Trenton Unit 5 and 6, Point Tupper Marine Terminal, Sydney International Coal Pier, and Steam General Assets. Also, the depreciation study reflects only partial decommissioning costs for hydro generation plants...

AI summary The Nova Scotia Energy Board's amended notice outlines proposed rate changes for multiple facilities, a depreciation study with partial decommissioning cost coverage, approval of a Cost-of-Service Study, continuation of a symmetrical Storm Cost Recovery Rider, and fee adjustments including AMI opt-out charges and pole attachment fee increases. A public hearing is scheduled for January 2026.

Metering The costs of metering vary according to the type of metering device installed. For residential and general service rate classes, the most common type of metering device is the electromechanical induction meter. In contrast, large...

AI summary The text discusses the varying costs of metering based on the type of metering device used, noting that residential and general service rate classes typically use electromechanical induction meters, while large users require interval meters. It also mentions that metering costs include capital, depreciation, and operating and maintenance expenses.

SPECIAL CONDITIONS - (1) Metering will normally be at the low voltage side of the transformer. Should the customer's requirements make it necessary for the Company to provide primary metering, then the customer will be required to make a c...

AI summary The special conditions outline requirements for metering, service provisions, load management, and system integrity. Customers may be required to contribute to capital costs for primary metering, own transformers, and ensure their load does not compromise the power supply system's integrity. Factors like reliability and voltage flicker are considered in assessing system integrity.

4.6 Implementation of New Rates (Cyber Incident Impact) [727] At the hearing, NS Power said that it now has communication with roughly 400,000 of its customer meters and has targeted the end of March to have all meters (approximately 555,0...

AI summary NS Power discussed implementing new rates affected by a cyber incident, noting challenges in prorating rate changes due to extended meter reading intervals. It acknowledged potential for higher charges during colder periods but emphasized progress with AMI technology, though historical data storage is limited to 60-90 days.

4.6.1 Findings [730] The Board is concerned that customers who have higher usage during the recent colder period of the year might end up paying more than the approved current rate for the electricity they are currently using because of th...

AI summary The Board is concerned that prorating electricity bills during a rate increase may unfairly burden customers with higher usage during colder periods, especially after a cyber attack prolonged meter reads. With AMI meters, precise energy usage tracking before and after rate changes should avoid prorating. The Board directs NS Power to justify prorating in its compliance filing or use AMI data to apply approved rates based on actual consumption timing.

SPECIAL CONDITIONS - (1) Metering will normally be at the low voltage side of the transformer. Should the customer's requirements make it necessary for the Company to provide primary metering, then the customer will be required to make a c...

AI summary The document outlines special conditions for metering and service provisions. It specifies that primary metering requires a capital contribution from the customer, and adjustments to meter readings are made when metering is on the high voltage side. Additional conditions relate to non-standard service provisions, load integrity, and factors affecting power supply system integrity.

Request IR-144: - Reference: Exhibit N-3 GRA Direct Evidence, Section 13.7, AMI Opt-Out Fee - a) Please describe any limits NS Power currently faces in reading AMI meters over the air as a result of its cybersecurity breach. - b) Please de...

AI summary Request IR-144 seeks information from NS Power regarding cybersecurity breach impacts on AMI meter readings, manual reading arrangements, timelines for resuming automated readings, and the accuracy of cost estimates for manual reading of opt-out customers in 2026–2027.

Request IR-146: - Reference: Exhibit N-8, Appendix 13A, page 7 of 14 - NS Power stated that approximately 41.5% of the total AMI project costs were for the AMI meters - themselves, and that most non-standard meters are also AMI meters, so...

AI summary NS Power stated that 41.5% of AMI project costs are for meters, with the remaining 58.5% covering components like labor and communication networks. The request asks what portion of these non-meter costs are not directly required by opt-out customers, implying a debate over cost allocation.

Request IR-148: - Reference: Exhibit N-8, Appendix 13A, page 8 of 14 - NS Power stated that customer-submitted meter readings can result in intentional misreporting - and that it could be challenging to accurately capture consumption readi...

AI summary NS Power highlights challenges with customer-submitted AMI meter readings, including potential misreporting and 177 accounts submitting postcard/photo readings in 2024. The proceeding requests details on incorrect readings, instructional materials, anomaly detection capabilities, and historical incidents since 2018.

on 5.1 allows for customersubmitted readings, NS Power still needs to receive, verify, and process these readings, along with handling disputes and correcting errors. [Exhibit N-8 Appendix 13A, p. 8] [675] In response to Board IR-148, NS P...

AI summary NS Power allows customer-submitted AMI readings but must verify, process, and resolve disputes. In 2024, 16 postcard and 161 photo meter submissions were received, though tracking accuracy is not done. Instructional materials are available online, with planned updates by 2026. NS Power can detect billing anomalies exceeding predefined thresholds.

3.10.2.1 Findings [680] The Board has several concerns with NS Power's request to implement AMI opt-out fees at this time. Based on the responses provided during the hearing, it appears that meter reader costs associated with opt-out meter...

AI summary The Board rejects NS Power's request to implement AMI opt-out fees, citing insufficient cost delineation, questionable forecasts (e.g., 20x increase in customer care costs), and reluctance to adopt self-reporting options for opt-out customers. NS Power's dismissal of self-reporting is challenged, as existing practices (e.g., accepting photo readings) contradict claims of feasibility issues. The Board directs NS Power to address these concerns in a compliance filing.

AI summary The tariff applies to three-phase electric power supplied to municipal electric utilities at the low voltage side of the bulk power transformer. Meter readings are adjusted by 1.1% for each transformation between the meter and the low voltage side to account for transformation losses. Readings are also reduced when metering occurs at transmission voltage.
