Eskom Holdings SOC has issued a tender to provide design, engineering, procurement, construction, construction management, start-up, commissioning, performance testing, operator training and maintenance (O&M), and two years of O&M services of a 17 MW solar power plant located at the Duvha power station.
The South African utility yesterday, December 15, issued the tender for its flagship coal-fired power plant in Mpumalanga. The addition of solar power is part of the company’s strategy to alleviate system constraints and decarbonize operations at the Duvha plant. The plant has been in operation since the early 1980s and is one of the largest fossil fuel plants in South Africa.
The scope of work includes the design of a solar PV plant with a minimum AC capacity of 17 MW and a maximum evacuation capacity of 30 MW AC on a 35.2 hectare environmentally friendly site within the Duvha power station at Witbank in Emalahleni Local Municipality.
Applicants are asked to submit their documentation electronically through Eskom’s website. The tender is open until January 30 at 10am, local South African time, and applications will be assessed against the issuance document in February.
In August 2025, Eskom issued a tender for 291 MW of solar capacity, with selected bidders entering into power purchase agreements (PPAs) with the utility for the energy produced. The purchased solar capacity would be put into use in phases. Projects had to be at least 10 MW to qualify.
