Stay informed about the latest developments in skid-mounted PV systems, prefabricated photovoltaic containers, containerized energy solutions, and renewable energy innovations across Africa.
Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to 2022.
These benchmarks help measure progress toward goals for reducing solar electricity costs and guide SETO research and development programs. Read more to find out how these cost benchmarks are modeled and download the data and cost modeling program below.
The cost of utility-scale solar in 2022 was down 84% from 2010. Solar power purchase agreements in the West were an average of $10/MWh lower than in other regions. Larger utility-scale solar projects (20 MW+) cost 26% less per MW than projects between 5-20 MW. Annual Energy Outlook, 2023.
Projected change in price by fuel type, 2022-2050 Solar, wind, and hydropower are based on the projected levelized cost of energy, which includes capital expenditures and operating costs, while natural gas, coal, and nuclear are based on the projected cost of only the heat content of these plants.
In 2023, BPC agreed to procure up to 600 MW of power generation from a yet-to-be-built coal-fired power station. Additionally, Botswana imports the bulk of its power from South African utility Eskom, and the rest from Nampower (Namibia), Zesco (Zambia), and the Southern African Power Pool (SAPP), to make up for any production shortfalls.
It was established in 1970 and is currently the only electricity supplier in the country. BPC represents Botswana in the Southern African Power Pool. Morupule Power Station (coal-fired) in Palapye supplies 80% of domestically generated electricity, however the country is dependent on importing energy from its neighbours.
Revised in April 2025, this map provides a detailed view of the power sector in Botswana. The locations of power generation facilities that are operating, under construction or planned are shown by type – including liquid fuels, gas and liquid fuels, coal, hybrid, hydroelectricity and solar.
Botswana Power Corporation (BPC) is a state-owned entity created by Act of Parliament in 1970. BPC is responsible for generating, transmitting and distributing electricity within the country to areas approved by the Ministry of Minerals, Green Technology and Energy Resources.
