Sidwawa Substation Upgrade

Innovative 3D modelling enhances safety, efficiency, and reliability at the Sidwawa Substation upgrade in the Eastern Cape.

Client

King Sabata Dalindyebo Local Municipality

Project date

Appointed in 2015

In 2015, Zutari was appointed to remove outdated equipment from the King Sabata Dalindyebo Local Municipality’s Sidwawa Substation and install new, upscaled equipment. The aim was to enhance the reliability and sustainability of electricity supply to customers and improve the substation’s overall capacity.

The opportunity

The existing equipment no longer complied with updated legislation governing fire risks and equipment safety. The proximity of the oil-filled equipment to high-voltage components posed a significant fire hazard in the event of an oil spill. Constructing firewalls to address this risk introduced another challenge, as the required firewall height created clearance issues with the overhead power lines.

What we did

To overcome these challenges, Zutari applied intelligent 3D modelling to develop detailed process documents outlining exact distances between structures and overhead lines. The 3D model provided a realistic visual aid, enabling engineers to adjust the layout and achieve compliance with electrical clearance standards while reducing oil spill risks.

The embedded intelligent data links within the 3D model’s equipment properties also boosted productivity and allowed engineers to plan and visualise work in confined spaces safely. By identifying and resolving safety issues virtually, the team was able to prevent potential on-site incidents.
3D modelling enabled Zutari engineers to optimise equipment layout and enhance safety before construction began.

The outcome

Through the use of advanced 3D modelling, Zutari successfully increased the substation’s capacity, safety, and operational efficiency. The project demonstrated the tangible benefits of digital engineering tools in managing complex, high-risk environments.

The Sidwawa Substation project was recognised for its innovation when Zutari was named a finalist in the 2015 South African Innovation Awards by MyWorld of Tomorrow, in partnership with Business Connexion and Business Day. The recognition reflected how the project positively impacted the environment, enhanced business performance, and showcased the efficiency gains made possible through intelligent design.

Zutari’s innovative approach to intelligent 3D modelling helped mitigate safety risks, improve efficiency, and deliver a compliant, future-ready substation.
