After the completion of the plants, Nigeria will be able to independently produce power transmission and transformation equipment and even serve other African countries.

Nigerian presidential spokesperson Garba Shehu said Nigeria has suffered a long-term power supply deficit, which is a major obstacle in the country's way of economic diversification, according to Xinhua News Agency.

"We expect the engineers to bring home what they have learned in China, and I'm sure they will do something in manufacturing indigenous electric devices and alleviating power shortages in the country," Shehu said.
