NON-CONFIDENTIAL 1 Request IR-14: 2 3 Please discuss the other alternatives and provide a justification that an immediate purchase 4 of a new transformer is the lowest cost option. 5 6 Response IR-14: 7 8 As provided in the response to IR-...
AI summary NSPI justifies immediate purchase of a spare transformer over constructing underground feeders, citing higher costs for duct banks and feeders. Congestion in Halifax Peninsula and 2010 ACE Plan cost data support the transformer option as lower-cost.
IR-19: With reference to the response to IR-6: - a) Describe any test results regarding the integrity of this third transformer. - b) On page 4 of 20 of the submission NSPI states: liThe remaining unit has been exposed to similar condition...
AI summary IR-19 queries NSPI on test results for a third transformer's integrity, risk assessment of a unit post-procedure, reinforcement measures for transformer integrity, and cost comparison between enhancements and replacement.
IR-28: Please provide and discuss assumed transformers' failure rates, and probabilistic risk assessments of the reliability of power supply to customers in the downtown Halifax area, for the following transformer configurations at the Kem...
AI summary The document requests probabilistic risk assessments and failure rate analyses for transformer configurations at Kempt Road Substation across six timeframes, including pre-2009, post-2010, and scenarios with spare transformers. It also asks for economic analyses comparing urgent transformer purchase versus delayed purchase, referencing prior IR-5(b) responses.
