ELECTRICITY FROM WOOD-FIRED GASIFICATION IN UGANDA - A 250 AND 10KW CASE STUDY Thomas Buchholza, Izael Da Silvab, John FurtadoC 8Gund Institute for Ecological Economics, University of Vermont, Vermont, USA, [email protected] bCentre of Excellence in Renewable Energy & Sustainable Development (CERESD), Strathmore University, Nairobi, Kenya CDepartment of Industrial Ecology, KTH Royal Institute of Technology, Stockholm, Sweden ABSTRACT Wood

of

an

operational

wood-based

and

gasification

systems (250 and 10 kW) installed in Uganda in 2007. Both

systems

proved

their

potential

to

compete

economically with diesel generated electricity when operating close to the rated capacity. At an output of 150 kW running for �12 h/day and 8 kW running for �8h/day, the systems produced electricity at US$ 0.18 and 0.34/kWh, respectively. A stable electricity demand close to the rated capacity proved to be a challenge for both

systems.
