Mauritania and Mali have taken a major step toward strengthening regional energy cooperation by signing key contracts for the construction of a high-voltage electricity interconnection project. The agreements were signed during an official ceremony held in late April 2026 and attended by Mauritania’s Minister of Energy and Petroleum, Mohamed Ould Khaled, along with the Minister of Economic Affairs, Abdallahi Ould Suleyman Ould Cheikh Sidiya.

The newly signed contracts are part of the larger 225 kV Mauritania-Mali Power Interconnection and Related Solar Power Plants Development Project, also known as PIEMM. The current phase focuses on the development of a 184-kilometer transmission line inside Mauritania. The project includes a 114-kilometer section linking Kiffa and Teintane, along with an additional 70-kilometer extension connecting Teintane to Ayoune. The contracts also cover the construction of modern substations in these areas to improve electricity transmission and distribution.

The interconnection project forms part of the African Development Bank’s “Desert to Power” initiative, which aims to transform the Sahel region into a major hub for solar energy generation. The Kiffa–Teintane–Ayoune section alone is estimated to cost around $135 million. Financial support for the project is being provided by several international institutions, including the African Development Bank, the Green Climate Fund, and the OPEC Fund for International Development.
