In June 2013, NamPower finalised a pre-feasibility study for a biomass power station. The pre-feasibility study assessed the technical, environmental, socio-economic and financial aspects of this project. It was recommended commercially proven combustion technologies be used for the conversion of biomass to heat energy for generating electricity. In 2018, a micro- and macro-economic impact assessment of a proposed 20MWe encroacher bush biomass power station was completed. More recently, in December 2019 a greenhouse gas assessment of biomass utilisation in Namibia included a proposed 20MWe encroacher bush biomass power station and in October 2020 an environmental impact assessment for a proposed 40MW encroacher bush biomass power station was published. It is against this background, that there is a need to update the existing macro-economic study completed for a 20MWe biomass power station to reflect the current market conditions and present the benefits should the project be implemented to an increased capacity of 40MWe or even in phases.
