Within the newly developed Guzape District in the heart of Abuja lays a unique 10-apartment block building. None of the apartments is connected to the electricity grid, although the grid has reached Guzape District. The building is running on a hybrid system of solar and wind energy, providing enough electricity for the residential apartments, including air conditioning. For Sulaiman Yusuf, the renewable energy entrepreneur behind the construction, the buildings are proof that Nigeria’s energy future has a large off-grid component. In this video Mr Yusuf explains the technical and financial set-up of the buildings.
