Abstract: Renewable energy in the past has been considered a costly venture and not until recently has the idea of exploiting natural resources been fully embraced. This has become a staple for most developing countries that are depending mostly on solar energy for electrification of rural areas. Rwanda is not an exception in this case and with this in mind the government in partnership with Gigawatt global embarked on a project to build the first-ever solar park of its size in the region (Gigawatt solar power plant) to further boost the energy sector. The study examined the various factors that influence renewable energy projects sustainability.
