Coupled with the adoption of the Rural Electrification Master Plan in 2008, Zambia was able to expand access to electricity from about 20 percent before 2010 to above 40 percent in 2019. The review of the National Energy Policy in 2019 marked the beginning of the third wave of sector reforms.

How is Zambia active in the energy sector?

The state is active in the sector in different ways, in policy-making through the Ministry of Energy (MoE) and through various state agencies, including Zesco itself. 1 The Rural Electrification Agency (REA) is mandated to provide electricity infrastructure in rural areas of Zambia.

What is the regulatory review of the electricity market of Zambia?

The regulatory review of the electricity market of Zambia is a result of a continental initiative to crowd-in private sector participation in Africa’s electricity market in collaboration with Member States, in this case the Republic of Zambia. This review process enjoyed cooperation from the Ministry of Energy, which was very valuable.

Is Zambia's energy strategy a symptom of a worsening energy deficit?
