Construction of the facility at Steven's Croft not only included the biomass plant but a fuel processing facility and 26km of underground electrical cable connecting the plant to Chapel Cross electriclal sub-station<ref name="SC" />. The fuel processing facility was designed to blend all the various sources of fuel mentioned above into one homogeneous material. It includes up to 14 days of round wood storage, a facility for reception of pre-chipped fuel, up to 6000m3 of covered chipped fuel storage, a round wood chipping facility, fuel reclamation and forwarding equipment with systems for final preparation of the fuel before delivery to the power plant.<ref name="SC" /> | Construction of the facility at Steven's Croft not only included the biomass plant but a fuel processing facility and 26km of underground electrical cable connecting the plant to Chapel Cross electriclal sub-station<ref name="SC" />.

Construction of the plant began in October 2005 with the plant entering commissioning in Autumn 2007 <ref name="tech" />. Construction was carried out by a Siemens/Kvaerner consortium with the boiler being a Kvaerner Power Bubbling Fluidised Bed power boiler, fuel handling and flue gas cleaning equipment<ref name="tech" />. The boiler conditions were designed to allow the best efficiency at 537°C, 137Bar with a capacity to raise 16 MWth of energy. The high steam conditions dictate the need for specialist corrosion resistant materials in the high temperature components and to control fuel quality.<ref name="SC" /> | Construction of the plant began in October 2005 with the plant entering commissioning in Autumn 2007 <ref name="tech" />.

The power plant can reach full output even with high moisture fuels. It is able to burn a maximum of 20% recycled wood (limited by Planning and [[IPPC]]) and a maximum of 20% short rotation coppice. Moisture content for the plant is between 46% and 58%, with a design blend of 53%<ref name="tech" />. | The power plant can reach full output even with high moisture fuels.
