4 MW waste-to-energy project in South Africa developed by Bio2Watt. The project utilises biomass wastes in the Gauteng area in a small scale power plant, and sells power to the local BMW factory by wheeling over the local municipal and Eskom networks. This is the first project of this nature in South Africa. Norfund provided preferred equity together with investment funds Chlorophyll and Bertha foundation while Bio2Watt and Bosch Projects provided common equity. The plant became operational in 2015.
Bio2Watt is the first commercially viable biogas from organic waste project in South Africa. The production of methane and carbon dioxide is a natural consequence of the degradation of organic waste. In a biogas plant this process is accelerated and the methane is captured and used to generate electricity using gas engines. The technology is established and commercially proven with many biogas plants operating in Asia, Europe and the Americas.
The generation capacity of the biogas plant is 4.2 MW, providing an estimated 35 GWh of energy per year. The Project is located in Bronkhorstspruit - a 40 minute drive from Johannesburg - on the premises of one of South Africa’s largest cattle feedlots (Beefcor) and an agricultural stronghold in the Gauteng province. The location provides the project with proximity to key feedstock supply, grid access and sufficient water.
The project will be constructed by the South-African construction and engineering company Bosch Projects. The Danish company ComBigaS will supply the biogas technology.
The power will be sold to a nearby BMW factory under a 10-year power purchase agreement (“PPA”).
