The Gambia is one of mainland Africa's smallest countries: a narrow strip of land following the River Gambia inland from the Atlantic, almost entirely surrounded by Senegal. Its size and shape matter a great deal for electricity. Distances are short, the land is low and flat, and the national grid is small. This note explains how those features shape the country's wind and solar prospects in general terms. For current figures, tariffs and plans, check official sources such as the national utility and the energy regulator.
A sunny, flat landscape
For much of the year, particularly in the long dry season, skies are clear and sunshine is strong, which makes solar the leading renewable option. Flat land makes installation simpler than in hilly countries. There are complications, though. The harmattan, a dry, dusty wind from the Sahara, can carry fine dust that settles on panels and dims the sunlight for days at a time, so regular cleaning and realistic output estimates matter.
What about wind?
Along the Atlantic coast, sea breezes are a familiar part of daily life. Whether they are strong and steady enough for turbines is a question only careful, on-site measurement can answer. Low coastal land also raises concerns about erosion and rising sea levels, which affect where any coastal infrastructure should go. Our guide to reading a wind map explains why general maps are only a first step.
The small-grid challenge
Small power systems have historically relied heavily on generators burning imported fuel, which can make electricity expensive and exposed to world oil prices. Adding solar can reduce fuel use, but a small grid can only absorb so much power that rises at midday and vanishes at sunset. Batteries, better forecasting and links to neighbouring grids all help. Because the country is surrounded by Senegal, regional interconnection is a natural part of the discussion.
Homes, hotels and farms
Coastal hotels, businesses and households may install their own rooftop systems to cut bills or cover power cuts. Upriver, solar is used for water pumping and irrigation, and in villages beyond the grid, small mini-grids can make sense.
Questions for any project
- How will output be affected by dust in the dry season?
- Can the grid take the extra midday power, or is storage included?
- Who buys the electricity, and in which currency?
