AI summary The document discusses capital expenditures and operational issues related to the maintenance and performance of diesel CT units, including variations in sustaining capital from 2021 to 2024 and failed starts on Burnside 3 due to instrumentation and system faults.

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.

- New Auburndale Substation by 2026 1 Request IR-6: 2 3 On page 27, NS Power stated that "The sustaining capital values for the diesel CTs has 4 decreased as compared to the 2020 IRP assumptions for 2023…" 5 6 (a) Please explain the factor...

AI summary The document discusses the sustaining capital values for diesel combustion turbines (CTs) and the factors influencing their changes from 2020 to 2023 and beyond. The response explains that decreased values in 2023 were due to deferred capital projects based on updated condition assessments, while the 2024 increase was driven by specific major projects such as a generator purchase and refurbishments.

Request IR-6: - On page 27, NS Power stated that " The sustaining capital values for the diesel CTs has decreased - as compared to the 2020 IRP assumptions for 2023… " - a) Please explain the factors contributing to the decreased sustainin...

AI summary Request IR-6 seeks clarification from NS Power on changes in sustaining capital values for diesel CTs, noting a decrease from 2020 IRP assumptions in 2023, a nearly doubling of values in 2024, and projected trends for 2025 and beyond. The inquiry focuses on factors influencing these changes and their alignment with the Integrated Resource Plan.

Request IR-7: - On page 39, NS Power provided the following statements: - Today manufactures can support between 5% and 35% hydrogen blending. - Current models would need to be retrofitted to operate using 100% hydrogen as a fuel source. •...

AI summary NS Power states current models require retrofitting for 100% hydrogen operation but not 35% blending. The 10% capital cost adder for hydrogen-capable turbines aligns with the Evergreen IRP. Questions seek clarification on retrofit needs for 35% blending and the 10% assumption's basis (hydrogen vs. diesel CT costs).

26 Request IR-3: 27 28 RE: Roadmap Item 2 29 30 (a) Please provide a summary of NS Power's seasonal fuel price forecast through 2030. 31 32 (b) Please provide a discussion of the current operational practices with respect to dispatch of 33...

AI summary Request IR-3 includes three parts: (a) requesting NS Power's seasonal fuel price forecast through 2030; (b) inquiring about operational practices for dispatching natural gas, HFO, and LFO; and (c) asking about the IRP's considerations for sustaining capital investment in thermal infrastructure. The request focuses on fuel forecasting, dispatch practices, and infrastructure planning.
