Reed canary grass is co-combusted with fuels like peat, bark, sawdust and forest chips. Typical moisture content of these fuels is about 50% on total weight basis and boilers in power plants are designed for fuels with that moisture content. Moisture content of reed canary grass is much lower (15–25%). In terms of energy the maximum annual share of reed canary grass has nowadays been only about 1% of the total annual fuel energy input at power plants. The highest momentary shares have been around 15% of the total fuel energy (20–30% in volume). The most critical limiting factor at the plant is normally the fuel conveyor and feeding capacity which are designed for much energy denser fuels. The energy content of reed canary grass chop is only 0.3 MWh m−3 while it is 0.6–1.1 MWh m−3 for wood and peat.
