Interrogatory: Question(s): What are the O&M costs (savings) for the like-for-like replacement and how were they determined?
AI summary The interrogatory asks for the operational and maintenance (O&M) costs (savings) associated with a like-for-like replacement and the methodology used to determine these costs.
Interrogatory: Question(s): On the RETScreen – Financial Analysis, how are the "O&M costs (savings)" calculated? What were the O&M costs prior to the December 2023 incident when the turbine was operating and what are they expected to be af...
AI summary The interrogatory asks how O&M costs (savings) are calculated in the RETScreen – Financial Analysis, and seeks information on O&M costs before and after a turbine refurbishment following a December 2023 incident.
Response: In the RETScreen Financial Analysis, the "O&M costs (savings)" line represents the estimated annual routine operation and maintenance cost for the Factorydale plant. It is not calculated as a direct savings against the historical...
AI summary The RETScreen Financial Analysis estimates the annual routine O&M cost for the Factorydale plant at $40,000/year, based on BEC's expected staff allocation. This does not include periodic overhauls or major maintenance, which are handled separately. Prior to the December 2023 incident, O&M costs were estimated at $115,000 to $150,000 annually for the 2015–2017 period.
Question(s): In several sections of Condition Assessment, Hysovent noted that consistent maintenance records and technical specifications for various equipment were not available. - (a) Please describe BEC's routine maintenance schedule an...
AI summary The document requests BEC to provide details on its maintenance schedules, record-keeping methods, and procedures for generating facilities and equipment. It also asks for copies of maintenance reports and explanations for any unavailability of records.
