1.0 SCOPE Nova Scotia Power Inc. (NSPI) completed an LIS for the proposed MLS Spaceport in 2022. The project was on hold until discussions were picked up again in 2025. Now that federal funding has been secured, the request has been made f...
AI summary Nova Scotia Power Inc. (NSPI) completed a Load Impact Study (LIS) in 2022 for the proposed MLS Spaceport, which concluded no transmission upgrades were needed for a 4 MVA load. However, with a new large load customer in the area and a revised in-service date of 2026, the 2022 LIS is no longer valid. Alternative distribution supply options for 3 MVA will be explored, while loads above 3 MVA would require a new or upgraded 69-25 kV source and a transmission interconnection request to IESO-NS.
2.0 PROPOSED LOAD MLS is proposing a new 4 MVA load facility in Canso to be connected by end of 2026 with operations to begin in 2027. Neither substation transformer 19C-T51 nor 24C-T54 have sufficient capacity to supply the full 4 MVA of...
AI summary MLS is proposing a new 4 MVA load facility in Canso, to be connected by the end of 2026 and operational in 2027. However, existing substation transformers 19C-T51 and 24C-T54 lack sufficient capacity to support the full 4 MVA load.

AI summary Transformer 19C-T51 currently supplies a peak winter load of 1.4 MVA and is not at risk of overloading. However, connecting a new 4 MVA load is not viable due to 4 kV feeder design limitations such as voltage drop and non-standard construction.
4.2 24C-T54 Transformer Loading Based on the available load check data, transformer 24C-T54 supplies a total peak winter load of approximately 6.3 MVA and is not at risk of overloading. 3 MVA of new load could be supplied from this transfo...
AI summary Transformer 24C-T54 currently supplies a peak winter load of 6.3 MVA and can accommodate an additional 3 MVA without exceeding 133% of its 7.55 MVA rating. Voltage regulators would be needed on circuit 24C-442 to maintain feeder voltage at Canso and the MLS Spaceport site.
4.3 19C New Feeder Loading In order to supply a 3 MVA demand load from the 19C 4 kV distribution system from a single feeder (built to 25 kV standards), it would need to be built with 556 ACSR conductor and two sets of 400 Amp 4 kV voltage...
AI summary The text discusses the technical considerations for supplying a 3 MVA demand load from the 19C 4 kV distribution system. It outlines the need for a single feeder with 556 ACSR conductor and two sets of 400 Amp voltage regulators, or alternatively, two feeders each with a set of voltage regulators. The alternative is not recommended due to the age of the transformer and non-standard construction.
