There are few technical barriers to building biomass-fired facilities
at any scale, from domestic to around 50 MW, above which
considerations of the availability and cost of providing fuel become
significant. In general however, the capacity and generating efficiency
of biomass plants are considerably less than those of modern
natural-gas fired turbine systems. The main non-technical
limitations to investment in larger systems are economic, or in
some countries reflect planning conditions and public opinion,
where a clear distinction may not be made between modern effective
biomass energy plant and older polluting incinerator designs.
