AI summary

Nova Scotia Power submitted Work Order CI# 40425 (Project T647) on November 24, 2010, requesting approval under section 35 to acquire an additional 138-25 kV, 25/33/42 MVA transformer for Kempt Road Substation, to be connected as an energized spare.
The application cites urgent system reliability concerns: four transformer failures at Kempt Road since 2001, including two units removed from service in July 2009 and September 2010 for factory rewinding and not yet returned, leaving only one transformer in service and a high risk of extended load loss.
Total project cost is estimated at $1,093,699 (zero dollars spent at time of filing), with materials comprising the dominant share at $936,905 — including $876,310 for the transformer itself — and expenditures split across 2010 ($280,115) and 2011 ($813,584); estimated in-service date is August 2011.
The justification notes that Kempt Road is located in a high fault-level area of the transmission system, subjecting transformers to extreme duty cycles, and that favorable manufacturer pricing supported advancing the project at this time.
