Société Mauritanienne d’Électricité (SOMELEC) — Ministry of Energy and Petroleum
Mauritania is carrying out an ambitious transformation of its electricity sector: developing generation capacity from gas and renewables, reinforcing transmission and distribution networks, adding energy storage and extending access to electricity.
The success of that transformation rests on a strong mobilisation of private investment, on public–private partnerships and on close cooperation with international partners — which is precisely why the portfolio was put on the table in Las Palmas.
This presentation is the project book itself: the generation projects under way, the 225 kV and 400 kV lines that will connect industrial hubs, inland cities and neighbouring countries, and the distribution and rural electrification programmes that turn all of it into service quality for households and businesses.
Three layers of the same programme, presented together: what generates the power, what carries it, and what delivers it.
Thermal plants — HFO/LFO and gas — alongside hybrid, solar and wind plants, hydroelectricity and battery storage.
225 kV lines: 1,500 km operational or in the final phase of construction and 1,200 km in project, plus transformer substations, regional interconnection corridors and 90 kV lines.
Reinforcement of the 33/0.4 kV networks and supply to cities and localities from the new substations.
Independent power producers are the core of the new generation capacity, combining gas from national fields with the country’s solar and wind resource.
A new combined-cycle plant next to the existing 180 MW plant in Nouakchott, supplied with natural gas from the Banda offshore field some 55 km out to sea.
An additional 60 MW taking capacity to 240 MW, with conversion to gas once the pipeline from Banda is completed.
Construction and maintenance of 10 solar plants with storage to hybridise SOMELEC’s diesel plants inland — a solution designed for off-grid sites. The project is currently entering its start-up phase.
Gas from GTA and Banda, 220 MW of new wind and solar with 375 MWh of storage, a 225 kV backbone reaching Zouerate, Néma and the Malian border, and 481 localities waiting to be connected — the portfolio is what industrialisation will run on.
Connecting the industrial hubs, the inland cities and the regional interconnections.
Connects the northern and mining zone to Nouakchott via Akjoujt and Atar. Commissioning expected end 2026.
Designed at 400 kV for initial operation at 225 kV.
A second circuit on the NKC–NDB line to secure the N-1 criterion.
A 90 kV line serving the agricultural zone.
Generation and transmission only count once they reach cities, towns and villages — which is what this part of the portfolio delivers.
Supplying the cities located along the new lines: Akjoujt, Atar, Kiffa, Néma and other localities.
A regional electricity access and battery energy storage technology project, electrifying 481 localities across Trarza, Brakna, Assaba, Gorgol and Guidimagha.
A 33 kV line linking Kaédi to Sélibaby along two routes, electrifying all the villages in between. Works are currently in progress.
The continuation of the SUD project completed in 2021; the project is entering its start-up phase.
A set of projects to improve electricity service quality in Nouakchott — public lighting, construction of 30 MV/LV substations and more. The programme is in its final phase.
The continuation of emergency plan I, due to start shortly.
Read as a business opportunity, the portfolio maps directly onto the capabilities represented around the round table.
