The International Energy Agency published on 1 April 2019 a commentary titled "Another Look At China's Involvement in the Power Sector in Sub-Saharan Africa" by David Benazeraf and Yilun Yan.
At least 24 countries have contracted new power plants to Chinese construction companies between 2014 and 2024. Zambia is the largest investor in Chinese-added capacity, followed by Nigeria, Angola, Uganda, and Cote d'Ivoire. These five countries make up about half of the capacity added or being added by Chinese contractors, mostly due to large hydro projects. Compared to the almost 30 percent of new capacity that Chinese companies built as of 2016, the role of Chinese companies in Sub-Saharan Africa capacity additions has declined to 20 percent.
