AI summary This project entails constructing an 8.5 km three-phase feeder from the 92H Tidewater Substation to relieve and double-circuit the existing 92H-331 feeder along Peggy's Cove Road. It aligns with a separate project (CI C0071888) to replace the 92H-T61 transformer with a 25 MVA unit, addressing winter peak-load overloads at the substation and feeder.

2.1 Transmission The Tidewater and Hammonds Plains substations are supplied from the 138 kV system in the Halifax area. The transmission network in this area is well interconnected and no transmission thermal or voltage limitations were id...
AI summary The transmission network in the Halifax area, which supplies the Tidewater and Hammonds Plains substations, is well interconnected and does not have thermal or voltage limitations that would constrain distribution alternatives. Transmission constraints are not a limiting factor in addressing distribution capacity issues.
7.4.3 Hammonds Plains Alternative C: Feeders from Lucasville Alternative C involves extending feeders from the 131H–Lucasville substation to offload 137H and increase contingency capacity. While this alternative avoids major substation con...
AI summary Alternative C proposes extending feeders from Lucasville to offload 137H and increase contingency capacity. It avoids near-term substation construction but requires long feeder lines with routing challenges. Reliance on Lucasville capacity limits regional supply flexibility and defers a new substation until 2029. The approach is deemed non-preferred due to limited long-term benefits and reliance on distant infrastructure.
2037: - Install a second transformer at 137H-Hammonds Plains. Implementation of these projects will restore compliance with planning criteria, provide sufficient contingency capacity, and accommodate forecast load growth in the Tidewater a...
AI summary The document outlines the installation of a second transformer at 137H-Hammonds Plains to restore compliance with planning criteria, ensure contingency capacity, and accommodate load growth in Tidewater and Hammonds Plains. Continued monitoring of development in Bedford West, Sandy Lake, and Hubley/Timberlea is recommended to adjust project timelines and identify long-term needs.
