Norwood GXP is a robust 220/66/11 kV facility with an N-1 capability and a total capacity of 180MVA. Its implementation involved the strategic division of the 220 kV ISL-LIV Cct 1 (ROX-ISL A line) and the establishment of a bifurcated 220 kV bus system which supports the capacity of Orion’s network in response to escalating load demands.
ElectroNet constructed and commissioned 8 x 220kV bays which included DCB’s, ES, CT’s, buswork etc. The scope also included the construction and commissioning of a full TP control room consisting of DC systems, comms, SCADA and full protection systems. In total the contracting group spent 18,850 hrs building and commissioning NWD substation.
