ecalled on two weeks' notice. Over the 2024/2025 winter period the unit was recalled to service four times by the NS Power System Operator to support firm customer load, generating a total of 128 GWh. In its 2024 and 2025 10-Year System Ou...

AI summary The document discusses the recall of the Lingan Unit 2 (LIN2) by NS Power to support winter firm load during the 2024/2025 and 2025/2026 winter periods. NS Power plans to keep LIN2 in cold reserve until new fast-acting generation resources are online. The IESO Nova Scotia also stated that LIN2 and Trenton 5 can only be retired once these new resources are in service and operating reliably.

espite the BESS and Wreck Cove resources, due to increasing system demands LIN2 will still need to be operated through winter 2029/2030 to maintain the planning reserve margin under NPCC requirements. The Board understands the transition o...

AI summary Despite the BESS and Wreck Cove resources, LIN2 will need to be operated through winter 2029/2030 to maintain the planning reserve margin. The Board acknowledges the transition of reliability functions from NS Power to IESO Nova Scotia under the More Access to Energy Act and approves the LIN2 2025/26 Capacity Requirement project to ensure firm capacity and reliability.

LIN2 2025/26 Capacity Requirement project was necessary to provide firm capacity for the 2025/26 fall and winter season. Accordingly, the Board approves the project in the final amount of $4,392,251. The Board considers LIN2 to present a u...

AI summary The Board approved the LIN2 2025/26 Capacity Requirement project for $4,392,251, acknowledging the unique circumstances surrounding LIN2's role in ensuring adequate planning reserve margin during the winter. However, the Board emphasized the need for ongoing oversight of LIN2's expenses due to its impending retirement and the dynamic nature of future capacity requirements.

AI summary LIN2 has been recalled multiple times during the 2024/2025 winter to support firm customer load, generating significant energy. NS Power states that LIN2 will remain in cold reserve until new fast-acting generation resources are online. The IESO Nova Scotia report (M12916) supports this, noting that LIN2 and Trenton 5 cannot be retired until reliable replacements are in service. NS Power also explains that battery energy storage and other resources are insufficient to replace LIN2's capacity due to increasing demand.

AI summary Despite existing resources like BESS and Wreck Cove, LIN2 will need to remain operational through winter 2029/2030 to meet planning reserve margin requirements under NPCC. The Board acknowledges the transition of reliability functions from NS Power to IESO Nova Scotia and the reduced reserve margins since 2023. The LIN2 2025/26 Capacity Requirement project was approved for $4,392,251 to ensure reliability.

AI summary The Board approved the LIN2 2025/26 Capacity Requirement project for $4,392,251 to ensure firm capacity during the fall and winter seasons. The decision was based on the need for cold reserve due to forced outages and limited import opportunities. The Board emphasized the importance of ongoing visibility on LIN2's expenses and directed NS Power to continue submitting LIN2 Cl projects as Winter Capacity Requirement applications.
