With a proven record as lead engineer for the soft desk conversion of the Ironbridge coal fired power plant (1990s), Craig Powers was selected by Capula as the control engineer for the plant's conversion to 100% wood biomass. The APACS PLC system was reconfigured for control of the new biomass hammer mills and associated draught plant. Other supporting changes were required to the master firing and draught controls. The work was carried out to a very tight timescale and budget. The work was carried out for Capula sub-contacted to Doosan.
