DESCRIPTION: This project was for the refurbishment of Lingan Unit 2 (LIN2) to safely operate and provide firm capacity required for system security through 2025 into winter 2026. Capital work was completed on critical plant equipment to e...

AI summary This document describes the refurbishment of Lingan Unit 2 (LIN2) to ensure safe operation through 2025 into winter 2026. Capital work was completed on various systems, including boilers, ash systems, electrical systems, and water systems. The Board directed NS Power to submit LIN2 CI projects as a single Winter Capacity Requirement application until otherwise directed.

Why do this project? This project was completed to allow Lingan Unit 2 to operate safely through 2025 and early 2026. Lingan Unit 2 is required to meet the demands of the NS Power system per the 2025 10-Year System Outlook (10YSO), which c...

AI summary This project ensures Lingan Unit 2 can operate safely through 2025 and early 2026. The unit is kept in cold reserve to maintain reliable supply for firm customer load, as outlined in the 2025 10-Year System Outlook. It will remain in reserve until new firm fast-acting generation resources are online and reliable.

Why do this project now? This project was completed to allow Lingan Unit 2 to operate through 2025 and the winter of 2026. NS Power has continued to minimize investment in Lingan Unit 2 in line with expected utilization using short-term al...

AI summary This project was undertaken to ensure the continued operation of Lingan Unit 2 through 2025 and the winter of 2026, as short-term mitigation strategies were no longer sufficient to maintain safe operations. The unit is necessary to meet capacity requirements during this period and is expected to be required in the same manner going forward.

Why do this project this way? NS Power is obligated to maintain sufficient firm capacity to meet its reliability obligations. Lingan Unit 2 was required for firm capacity for customers during the 2025/2026 season and is expected to be requ...

AI summary NS Power is maintaining Lingan Unit 2 to ensure firm capacity and system reliability until new resources are available. The Board has approved operating expenditures for LIN2 up to the end of 2024 but requires further approval for expenses beyond that date. The decision highlights the need for cost recovery and prudence in operations.

The increase of $1,230,048 from the 2026 ACE Plan subsequent submittal estimate of $3,162,203 is primarily due to the project scope being unknown until equipment could be brought offline to open and inspect for condition, and refurbishment...

AI summary The increase in the 2026 ACE Plan estimate is due to unforeseen refurbishment and replacement requirements identified after inspecting equipment at LIN2. Increased utilization of LIN2 has led to higher maintenance needs.

AI summary The document references the IESO-NS 10 Year System Outlook Report, indicating that the thermal retirement schedule aligns with 2030 coal phase-out targets. Due to rising demand, Lingan 2 is expected to remain operational through the winter of 2029/2030 to ensure adequate reserve margins until new fast-acting generation is available.

Request IR-1: - a) What is the current rated capacity (in MW) of the LIN2 generating unit? - b) Please provide an estimate of the power generation from this unit for 2026 to 2030. - c) Please extend the table requested by Board staff in IR...

AI summary The document contains three requests (IR-1, IR-2, IR-3) to Nova Scotia Power Incorporated (NSPOWER) regarding the capacity of the LIN2 generating unit, reserve margins for 2026-2027, and firm import options from New Brunswick and Newfoundland. It seeks information on generation estimates, energy substitution, and capacity planning.
