This tender seeks proposals for the refurbishment of Control and Protection systems for a 275 kV / 11 kV ±50 MVAR STATCOM at Garona substation. Key requirements include technical scope, estimated costs, and implementation timelines.
The National Transmission Company South Africa (NTCSA) is inviting submissions for a Request for Information (RFI) regarding the refurbishment of Control and Protection systems on an existing 275 kV / 11 kV ±50 MVAR STATCOM located at Garona substation. The project aims to enhance the reliability and performance of the STATCOM, which has been operational since 2013 without significant refurbishment. Interested suppliers are required to provide a detailed technical scope, indicative costs, and a proposed timeline for implementation.
The refurbishment will focus on the Control and Protection systems while evaluating the feasibility of retaining existing components, such as the RXPE VSC IGBT valves. Suppliers are encouraged to outline any challenges associated with partial refurbishments versus complete replacements. The RFI also seeks information on the suppliers' capabilities to provide ongoing support services, including maintenance and diagnostics, ensuring the long-term operational efficiency of the STATCOM. This project represents a critical investment in the infrastructure of the electrical grid, aimed at improving voltage stability and supporting the integration of renewable energy sources.
This tender is suitable for engineering firms, electrical contractors, and companies specializing in power systems and FACTS technology. Businesses with experience in refurbishing control systems and providing ongoing maintenance support are particularly encouraged to apply.
