The engineering, procurement and construction (EPC) division of electromechanical equipment manufacturer ACTOM is building the 1 000 MVA main transmission substation for the Overberg wind farm, near Swellendam, in the Western Cape. The substation, which will be completed in December, will ensure electricity generated by the wind farm, being developed by renewable energy independent power producer (IPP) Red Rocket, can be delivered reliably into the grid.
