Senegal includes the westernmost point of mainland Africa, the Cap-Vert peninsula on which Dakar stands. From there, a long sandy coast runs north towards the Senegal River, while the south becomes greener and wetter towards the Casamance. The result is a country with a windy shoreline, a sunny interior and a grid that grew up around the capital. This page explains the general factors; for current figures and plans, check official sources such as the energy ministry and national utility.
The Grande Côte
The coastline north of Dakar, often called the Grande Côte, faces the Atlantic trade winds for much of the year. Flat terrain helps: turbines meet smooth, steady air, and large components can be moved more easily than in hill country. Sand, salt spray and coastal erosion are the practical worries, and the same strip of land is valued for market gardening, fishing communities and tourism, so siting needs careful local consultation.
Sunshine, north and south
The Sahelian north and centre are hot and dry, with strong sunshine for most of the year. The south has a longer rainy season and more cloud, but still enough sun for solar to be useful. As in other Sahel countries, the dry-season harmattan haze and dust affect output, so panel cleaning matters.
One big load centre
Much of the demand is concentrated around Dakar and other western towns, while some of the best solar land lies inland. A grid built around one major city needs reinforcement to carry power from new sources, and it has to manage variable supply without blackouts. Storage and flexible generation are part of that picture.
Islands and river villages
Senegal has island and delta communities, for example in the Saloum, as well as villages along rivers where extending the grid is awkward. Solar mini-grids and hybrid systems are often the most practical way to provide power for homes, ice-making and small businesses in such places.
Gas, oil and choices
Offshore oil and gas discoveries have added a new dimension to Senegal's energy planning. How much weight goes to renewables versus gas is a policy choice that can change, so readers should follow official publications rather than older assumptions.
Financing questions
- Is the buyer the national utility, and how secure are its payments?
- Will new transmission be ready when a project is finished?
- How are local communities involved and compensated?
