About

Built on the plant floor

Tshepang Thapelo Engineering is led by Ronald Kgomo, a Red Seal qualified electrician from eMalahleni.

Ronald has spent fifteen years in industrial and mining work, most of it on coal plant electrical and instrumentation maintenance. He has worked as an instrumentation electrician on a Witbank plant, as an electrical technician on a coal mine, and came up through the trade as an electrician's assistant.

At a coal processing plant he cut filter press breakdown callouts by half within two months, ending the site's reliance on OEM callouts. On a coal mine's PLC fuel management system, the site ran a full year without a breakdown longer than an hour and reached 800 lost-time-injury-free days.

His approach is "Simplicity is genius": understand the problem, then build a fix that is safe, reliable and easy to maintain.
