Work is delivered directly for plant owners and through electrical contractors and EPC / systems integrators.
Sasol, Sasolburg
Designed and commissioned several plant MicroSCADA systems, then kept extending them for years: new substations added one by one, power stations brought onto the system, and maintenance contracts to keep them running. Later extensions were IEC 61850 systems.
Sasol, Secunda
Designed and commissioned MicroSCADA systems for plant areas, and extended them to further substations. Engineered and upgraded substation SCADA systems in 2023 and 2024, and acted as on-site engineering support for six months in 2023.
EPC and systems integrators
SCADA engineering and commissioning support for electrical EPC contractors and systems integrators, including Proconics and Iyanda Power Technologies.
132 kV IEC 61850 substation
