Why do this project now? Feeder 92H-331 has a winter peak load beyond the 325 Amp, NS Power Capital Expenditure Justification Criteria (CEJC) and has experienced cold load pickup issues, as observed during the February 4, 2024 extreme cold...
AI summary Feeder 92H-331 exceeds NS Power's 325 Amp design criterion, faces cold load pickup issues, and has a 4% annual load growth rate. Adjacent feeders are also over capacity, limiting operational flexibility. A new feeder is proposed to reduce loading, improve voltage, and enhance reliability. The project is deemed in-service after infrastructure upgrades by July 2026, with a Final Cost Date in June 2027.
Contingency Statement Contingency for this project has been determined using a combination of internal subject matter expert (professional engineers, capital planner and Power Line Technicians) previous experience and site-specific knowled...
AI summary The contingency for the project is set at 15% based on internal expertise, site-specific knowledge, and non-binding guidelines, classified as a Class 3 estimate. Risks covered include equipment replacement, environmental mitigation, and additional labor requirements.

EXECUTIVE SUMMARY This study evaluates capacity constraints affecting the 92H-Tidewater and 137H-Hammonds Plains substations and identifies capital investments required to maintain compliance with NS Power planning criteria and accommodate...
AI summary This study identifies capacity constraints at 92H-Tidewater and 137H-Hammonds Plains substations, recommending capital investments to meet NS Power planning criteria and accommodate load growth through 2035. Key projects include transformer replacements, new feeders, and the Stillwater Lake substation. These upgrades aim to restore compliance, improve reliability, and address forecasted overloads.
1.0 SCOPE This study was initiated to address transformer and feeder overloads at the 92H-Tidewater and 137H-Hammonds Plains substations. Both substations have experienced sustained loading above planning criteria during recent winter peak...
AI summary This study addresses transformer and feeder overloads at 92H-Tidewater and 137H-Hammonds Plains substations due to sustained winter peak loading and forecasted residential growth. It evaluates alternatives to meet planning criteria (133% transformer loading, 325 A feeders) and contingency capacity (e.g., mobile transformers, load transfer) over a 15-year period, recommending capital investments to resolve overloads and ensure reliability.
6.1.1 92H-T61 Replacement Winter peak load supplied by transformer 92H-T61 significantly exceeds the transformer rating when hydro is unavailable. Replacement with a new 15/20/25 MVA transformer is required. Monitoring limitations, rapid l...
AI summary Transformer 92H-T61 is overloaded during winter when hydro is unavailable, requiring replacement with a larger unit. Temporary solutions like modified hydro dispatch and mobile transformers are insufficient. Alternatives such as load transfers or adding a second transformer are infeasible due to infrastructure constraints and high costs. Replacement remains the only viable long-term solution.
7.1 Estimates Below are preliminary capital cost estimates by year for capital items associated with the alternatives discussed in Sections 6.2 and 6.3. The economic analysis in Section 7.2 will determine the NPV of these alternatives. Tab...
AI summary Preliminary capital cost estimates by year are presented for alternatives discussed in Sections 6.2 and 6.3. These estimates will inform an economic analysis in Section 7.2 to determine the NPV of the alternatives, focusing on capital expenditures and cost considerations.
7.4.2 Hammonds Plains Alternative B: Second Transformer at Hammonds Plains Adding a second transformer at 137H provides additional substation capacity and improves operational redundancy at the existing station. The 137H site was originall...
AI summary Alternative B proposes adding a second transformer at Hammonds Plains to enhance substation capacity and redundancy. While it resolves feeder capacity issues, it introduces reliability risks from long feeders, construction challenges due to heavy development along Hammonds Plains Road, and defers a Stillwater Lake substation until 2032, increasing overall costs. These factors make Alternative B less favorable than Alternative A.
7.5.1 Tidewater Alternative A: Hubley Conversion and Transfer to Stillwater Lake This alternative converts portions of the Hubley distribution system from 12 kV to 25 kV and transfers this load to the proposed Stillwater Lake substation. T...
AI summary Tidewater Alternative A involves upgrading Hubley's distribution system from 12 kV to 25 kV and transferring load to the Stillwater Lake substation. This reduces Tidewater substation loading, improves reliability via new feeder ties, resolves feeder overloads, and leverages existing infrastructure, making it the lowest-cost, preferred long-term solution.
