ESKOM BLANCO NETWORK STRENGTHENING: NARINA 400/132KV SUBSTATION AND DROERIVIER-PROTEUS 400KV LINE LOOP-INS WITHIN THE GARDEN ROUTE DISTRICT MUNICIPALITY OF THE WESTERN CAPE PROVINCE.

Eskom Holdings SOC Ltd., through their Transmission Grid Planning division have identified transformation constraints at Proteus MTS as well as the sub-transmission constraints on the network supplying the Blanco area located in the Western Cape Province. Eskom Transmission Grid Planning investigated various possible solutions to address these constraints. The establishment and operation of a new 400/132kV Narina MTS with associated LILO powerlines close to the load centre (i.e. central distribution point) located within the Blanco area was ultimately found to be the best technical solution. The required area size for substation location is 600m x 600m to account for current and future needs/plans. The length of the turn-in lines (loop-in loop-out on the Droerivier Proteus 400kV line and the Proteus Blanco 132kV line) will be determined by the approved substation location.
