Why do this project? This capital expenditure is required to relieve overloaded equipment. The East Dartmouth 25kV feeder circuit 113H-442 supplying Caldwell Road, Cow Bay and the Eastern Passage areas of Dartmouth exceeds overload criteri...

AI summary This capital expenditure is necessary to address an overloaded 25kV feeder circuit (113H-442) in East Dartmouth, which supplies Caldwell Road, Cow Bay, and Eastern Passage areas. The 2008-09 peak load reached 432 amps, exceeding the 325-amp overload criteria.

Why do this project now? This project is required to restore overload criteria and provide for further development in this area.

AI summary The project is necessary to address current overload issues and facilitate future development in the area. It aims to restore criteria that ensure system reliability and accommodate growth, which is critical for maintaining infrastructure integrity and supporting expansion efforts.

b) Justification In its application, NSPI justifies the need for this project by stating: This capital expenditure is required to relieve overloaded equipment. The East Dartmouth 25 kV feeder circuit 113H-442 supplying Caldwell Road, Cow B...

AI summary NSPI justifies a capital expenditure to relieve an overloaded 25 kV feeder circuit in Dartmouth, citing a 2008-09 peak load of 432 amps exceeding the 325-amp overload criteria. However, the critique notes that normal operating conditions show 300-amp loads, with the higher peak attributed to load transfers, suggesting NSPI's justification may be misleading.
