NAIROBI, Dec. 27 (Xinhua) -- China has made great contributions to narrowing Africa's power deficit, a perennial problem that still leaves two thirds of the population in sub-Saharan Africa without access to reliable electricity supply.

In 2017, Chinese firms have successfully built or are in the process of building many hydro-power plants across the continent.

These projects are located in a good many African countries including Cote d'Ivoire, Uganda, Zimbabwe, Angola and the Democratic Republic of the Congo (DR Congo).

When all projects are finished, they are expected to create nearly 3,700 MW of electricity for the continent. (1 MW=1,000 KW)

The construction of all these projects have also created tens of thousands of jobs for the locals.

The following is a list of six Chinese-constructed hydro-power plants, some of which are already commissioned, or still under construction in 2017.
