2025 Evergreen IRP Action Plan and Roadmap Update (NSEB M12247) NSPI Responses to Consumer Advocate Information Requests 1 Request IR-2: 2 3 RE: Action Plan Item 2b 4 5 Please provide a description of data that NS Power monitors, or antici...

AI summary NSPI responds to a request for information on data monitored to understand electrification impacts. The response references the 2025 IRP Action Plan Update and mentions the use of annual load forecasts, SCADA, and AMI data for monitoring. Some data, like interconnection requests, are accessible on the NS Power Oasis site.

NON-CONFIDENTIAL 1 Request IR-1: 3 Automatic Generation Control (AGC) functionality required from new wind farms 4 (beginning with the Rate Base Procurement projects), which will reduce curtailment 5 relative to what would be achieved by f...

AI summary The document discusses requests related to Automatic Generation Control (AGC) functionality for new wind farms and modeling of transmission and distribution systems. It includes questions about system modeling, feeder peak patterns, and data usage, along with responses from NSPI regarding modeling practices and data collection plans.

AI summary NS Power has identified overloaded feeders and substation transformers in its 2024 Feeder Assessment and System Load Snapshot reports, which are expected to become overloaded within the next 5-10 years. These assessments are directional and not detailed in terms of capital requirements, but they guide further planning studies to identify necessary upgrades and evaluate alternative solutions.

This report provides a moment in time summary of substation loading (and an estimation on average feeder loading) for the system peak that occurred February 21st, at 7:30am. This 2024 System Snapshot is used to flag potential substation, f...

AI summary This report provides a snapshot of substation and feeder loading during the system peak on February 21st, 2024, identifying transformers operating above 100% of their nameplate rating and feeders with average loading above 300A. It outlines methods used to determine loading conditions and discusses how Distributed Energy Resources (DERs) affect substation load calculations. The report also references the Capital Expenditure Justification Criteria for transformer upgrades.

NON-CONFIDENTIAL 1 Request IR-4: 20 Brushy Hill is currently under review. 21 22 2. Adjust corridor flow limits related to contingency loss of L-6503 with L-8003 out 23 of service. 24 25 Contingency loss of L-6503 is noted to cause overloa...

AI summary The document discusses adjustments to corridor flow limits and Remedial Action Schemes (RAS) to address potential overloads and accommodate future generation additions. It highlights short-term solutions like limiting corridor flows and long-term planning for upgrades as the power system evolves.
