President of the Union of the Comoros, H.E. Azali Assoumani, has inaugurated three solar power plants financed by the Abu Dhabi Fund for Development (ADFD) as the island nation seeks to strengthen energy security and reduce its heavy dependence on imported diesel.
The project, financed at approximately AED84.4 million, has been implemented by Abu Dhabi Future Energy Company PJSC, Masdar, and managed by Global South Utilities (GSU).
The three solar photovoltaic plants have a combined installed capacity of approximately 20 MW, comprising 12.86 MW on Grande Comore, 4.05 MW on Anjouan and 3.1 MW on Mohéli.
The project also includes battery energy storage systems with a combined capacity of 16 MWh and a power output of 8 MW across Grande Comore and Anjouan. Approximately 30 km of 20 kV medium voltage overhead transmission lines have also been installed as part of the project.
Technical studies estimate that the three plants will generate approximately 33.75 GWh of clean electricity each year. This is equivalent to the electricity requirements of around 17,500 households and is expected to avoid approximately 20,900 tonnes of carbon dioxide emissions annually.
The new solar capacity comes as Comoros faces significant constraints across its electricity sector. Imported diesel accounted for 91% of the country’s energy mix in 2024, highlighting the vulnerability of the power system to international fuel prices and supply disruptions.
Electricity demand reached 254 GWh in 2024, while actual generation stood at only 150 GWh. The country recorded approximately 3,000 power outages during the year, underlining the gap between electricity demand and available generation capacity.
The solar plants are expected to produce electricity equivalent to approximately 13.3% of total electricity demand in 2024 and 22.5% of actual generation.
The project is therefore expected to contribute to greater diversification of the country’s electricity supply while reducing the amount of diesel required for power generation. The addition of battery storage should also support system flexibility and help the electricity network manage variable renewable generation.
The UAE backed project forms part of wider efforts to deploy renewable energy infrastructure in developing markets, with the investment intended to support Comoros’ economic development while improving the reliability and sustainability of its electricity system.
