138 kV Substation – Joffre Plant

CIMA+ designed a new substation to support the expansion of NOVA Chemicals’ polyethylene production facility.

NOVA Chemicals Corporation is expanding its polyethylene capacity in Joffre, Alberta, through the addition of a 431 KTA (950 million lbs/year capacity), single train, linear low-density polyethylene unit, based on NOVA Chemicals’ gas phase polyethylene technology. With this expansion in mind, NOVA Chemicals opted to build a new 138 kV substation dedicated to supplying power to the new facility. The substation is fed by tapping the two existing NOVA-owned 138 kV overhead lines that connect the cogeneration facility to the Altalink 535S substation. CIMA+ was part of a consortium with PCL Intracon for this EPC project, and was responsible for providing detailed engineering including design, major apparatus specification, transmission lines, civil/earthworks, foundations and structural, electrical layout, control and protection, telecontrol/SCADA, and telecommunications, as well as on-site support and commissioning.
