The extent of grid electricity is limited and mainly concentrated near Kigali. Most of the country uses as its main energy source. Rwanda is planning to expand from 276 MW of grid power in 2022 to 556 MW in 2024 and may import some additional electricity from neighboring countries. In addition, it is installing small solar units throughout the country to ensure that households located in off-grid areas have access to electricity, or to help deal with power outages. Currently, the government plans to brin.
