Expression of Interest (EoI)

Botswana’s national power utility, the Botswana Power Corporation (BPC), is currently operating 600MW (4 X 150MW) Morupule B Power Station, and is also in the process of refurbishing Morupule ‘A’ Power Station (MAPS), which consists of 132MW (4 X 33MW) units.

The two stations are located about 270 km North East of the capital city, Gaborone at a place called Palapye in the Central District.

Morupule ‘A’ Power Station

Morupule ‘A’ Power Station Boilers employ a Pulverised Fuel technology and are of Natural Circulation type – designed and manufactured by Lungi Lentjes, Germany.

The installation and commissioning was achieved in 1986 (Phase 1) and 1988 (Phase 2) respectively. Since then all the four units have been in operation until July of 2012 when they were shut down as it was no longer economically viable to run the power station due to low unreliability emanating from too frequent breakdowns. Subsequently the power station was put under care and maintenance as preservation measure.

With environmental impact management taken into consideration, MAPS will come back in operation with Flue Gas Desulphurisation (FGD) of Dry-type desulfurisation process with sodium bicarbonate (NaHCO3) being injected into the flue gas path to guarantee desulfurisation facility’s level of assurance.

The fly ash production for MAPS is about 300 tonnes per day. The commercial operation of the plant is expected to be up to 15 years before it could be refurbished once again.

Morupule B Power Station

Morupule B Power Station (4 X 150MW) is coal-fired power plant that uses circulating fluidised bed combustion (CFBC) technology.

The plant uses an ultra-high pressure CFB boiler manufactured under the cooperation between WUXI Huaguang Boiler Co. Ltd and German LENTJES Company.

The first unit was commissioned in 2012 and the fourth unit was commissioned during the last quarter of 2013. The power plant uses limestone (CaCO3) to trap sulphur dioxide gas and therefore reducing the SOx emission into the atmosphere and in order meet the World Bank and local air pollution emission standards.

The installation of electrostatic precipitators in the power plant also helps to minimise the particulate emissions.

Morupule B Power Station produces fly ash as one of its combustion by-products. The design fly ash production from each unit is 440 tonnes/ day—commercial operation of the plant is expected to be up to 30 year.
