Why do this project? The load on the 69kV system in the Annapolis Valley has increased to a level where a loss of some source elements (138kV line or 138-69kV transformer) in the area, under peak load conditions, causes the voltage on the...

AI summary The load on the 69kV system in the Annapolis Valley has increased, requiring an additional 138kV supply to maintain reliability during peak load periods. The project involves interconnecting a new 138kV line from 43V-Canaan Road to 51V-Tremont at the 43V-Canaan Road Substation.

Why do this project now? The 2010/11 peak load on the 69kV system in the Annapolis Valley is forecasted to meet levels during peak load conditions which cause the voltage on the 69kV system to drop below acceptable levels which could resul...

AI summary The 2010/11 peak load on the 69kV system in the Annapolis Valley is forecasted to cause voltage levels to drop below acceptable standards, potentially leading to outages.

Two (2) new 30m radio towers will be required at the Canaan Rd. and Tremont Substations. NSPI's existing microwave radio and SONET fibre network backbones will be used to provide the communications to 415H Ragged Lake for SCADA. A new Alca...

AI summary The document outlines the communication infrastructure upgrades required for the Canaan Rd. and Tremont Substations, including the installation of new radio towers, the use of existing microwave and fibre networks, and the replacement of RTUs as part of the SCADA system upgrade. The SCADA group is evaluating the capacity of the Canaan Rd. RTU for the project.
