Nova 535S Substation

Substations Protection & Controls

This project involved the construction of a grassroots switchyard to facilitate the interconnection of Nova Chemical Corporation s new 400 MW cogeneration facility to TransAlta Utilities Corporation s grid.

Westpark s contract required the erection of all structural steel, installation of 29 - 138kv airbreak switches, 23 - 138kv voltage transformers, 11 - 138kv circuit breakers, associated 138kv buswork, all protection and control modules and related wiring, ground grid, lighting, station fencing and insulating gravel placement.

Tie-ins to the existing Nova substation required excavation and cable installation through the Nova station in tight quarters while maintaining service to the plant. This work required detailed planning and risk assessment, as well as careful attention to working clearances.

Westpark was able to complete the work ahead of schedule due to careful work planning, carefully selected manpower and excellent client relations.
