- Bid: RM14P
- Partners: Perpetua Holding
- Location: Eastern Cape and Northern Cape
- Awarded: 18 March 2021
- FID: Q1 2022

- Capacity: 75 MW dispatchable power, based on a combination of Wind, PV and BESS installed capacity
In March 2021, the consortium composed with its partner Perpetua Holding, won the Umoyilanga project in the Risk Mitigation IPP Procurement Programme (RMI4P), developed by the Government. EDF Renewables achieved Commercial and Financial Close on the Project in November 2023, reaching Commercial Close with the Department of Mineral Resources and Energy, and then concluding Financial Close with Nedbank, RMB and DBSA. This follows the signing of the Power Purchase Agreement (PPA) with Eskom, and the Implementation Agreement (IA) with the Department of Mineral Resources and Energy in August 2023. The project is currently under construction, with COD expected in the second half of 2025.
This innovative project combines solar, wind and battery storage technologies to offer dispatchable and reliable power to the national electrical grid. The project will operate as a virtual power plant, combining generation from two sites which are 900 km apart, namely Avondale in the Northern Cape, with 115 MW of solar PV and 30 MW of battery storage, and Dassiesridge in the Eastern Cape, with 63 MW of wind and 45 MW of battery storage.
The unique combination of wind and solar resources with batteries, enables Umoyilanga to provide 75 MW on demand from 05:00 to 21:30 as per the requirements of the PPA, and demonstrates that renewable energy can provide reliable, dispatchable power at a competitive price.
To achieve this, batteries at Dassiesridge will generally charge from the wind energy at night, discharging power in the morning until the sun rises. The solar installation at Avondale will supply the bulk of the energy during the day, supplemented by wind energy from Dassiesridge. Excess solar energy will be used to charge the batteries at Avondale, which will discharge after sunset. A sophisticated energy management system will give instructions to assets across both sites to optimise the power supply in real time, depending on weather forecasts and Eskom’s requirements. The low-carbon electricity produced, will help to meet the electricity needs of 120 000 households for 20 years, based on the Eskom residential consumption average of 3 319 kWh/household.
To deliver the Umoyilanga Project, EDF Renewables has signed contracts with major contractors for each technology including:
- A turnkey EPC Agreement with China Energy Engineering Corporation (CEEC), to proceed with the final design, procurement, and construction of the 115 MW Avondale PV plant;
- A Turbines Supply and Installation Agreement with Vestas, to proceed with the erection of 14 wind turbines of 4.5 MW on Dassiesridge;
- A Wind Balance of Plant Contract with Power Construction and Adenco Construction, to build all required infrastructures on Dassiesridge; and
- A Battery Energy Storage System Supply Agreement with Sungrow Power Supply, to deliver battery systems to both sites.
