Mainstream nears completion on country's first 'self-build' substation

Manie Kotze, Construction Project Manager for Kangnas Wind Farm, explained: “This is a huge project allocated by Eskom TX to a developer, as an entire self-build from greenfield construction to fully commissioned substation.”

Ground on the Kangnas Wind Farm was broken in June 2018 and 19 months later construction remains on time and on budget, with all civil works having been completed and more than half of its turbines now erected.

Additionally, 80% of the turbine components have now made the journey from Atlantis and Saldanha on the west coast, and delivery of all 610 components to the Northern Cape site is expected to be finished by the end of February.

Construction work will stop in mid-December for a month, before the final run-in to Kangnas Wind Farm entering commercial operation in late August 2020.

The project’s 160MVA transformer is scheduled to be handed over at the end of January, followed by the 250MVA transformer a month later.

Kotze added: “Once the two major transformers are installed and all Pad Mount transformers are in place, commissioning and testing will commence on completed circuits, while the final erection of turbines will continue in remaining circuits, followed by GRID Code compliance testing.”

Last month plans were announced to run Eskom’s transmission arm as a standalone subsidiary, Eskom TX, that will buy power from private and public sources and then sell it to the distribution business of Eskom.
