Maun Concentrated Solar Power Station

The Maun Concentrated Solar Power Station, is a planned 100 MW concentrated solar power station in Botswana. The solar power complex would be owned and operated by an independent power producer, whose identity will be revealed when the ongoing open bidding is concluded. Bids were received until June 2022. The power off-taker is Botswana Power Corporation (BPC), who will purchase the power for integration into the national grid, under a long-term power purchase agreement (PPA). This power station is being simultaneously developed, together with the 100 MW Letlhakane Concentrated Solar Power Station.

Location
The power station would be located in the city of Maun, in Ngamiland, approximately 851 km northwest of Gaborone, the capital and largest city of Botswana.

Overview
The power station will be designed with concentrated solar power (CSP) technology. Under this system of power generation, energy from the sun is trapped by curved mirrors. The light is concentrated to generate heat in the range of 400-500 C. That heat is used to heat water to create steam, which is used to turn electric generators. The design may include the use of molten salts technology to store electricity and release it after sunset and/or before sunrise.

Timeline
The tender documents call for the power station to commence commercial operations in the 2026/2027 financial year (July 2026 to June 2027).

Other considerations
As of September 2022, Botswana's national electricity demand was estimated at 550 MW. At that time national generation capacity was 450 MW. The country imports an additional 150 MW from South Africa. The government of Botswana has plans to increase its installed capacity by developing new solar power stations, thereby achieving energy autonomy from South Africa. This power station is part of those efforts.
