In 2017 Lesedi was awarded another Balance of Plant (BOP) Gas Turbine Power Station contract for the Ankerlig Transmission Koeberg Second Supply (ATKSS) Project. The ATKSS Project is a new off-site 132 kV back-up gas turbine power station, replacing the existing Acacia gas turbine power station for Eskom. It will be built next to the Ankerlig Gas Turbine Power Station in Atlantis.
The new power station will supply power to Koeberg Nuclear Power Station in the event of a 132kV loss to safety related power critical plants needed when it is necessary to shut Koeberg Nuclear Power Station down safely or recover to production status.
