Case Study: Co-firing biomass with coal at the Dunedin Energy Centre, NZ

Co-firing of biomass with coal at the Dunedin Energy Centre - Energy for Industry purchased the Dunedin Energy Centre from the Otago District Health Board (ODHB) in 2002 under a BOOT partnership (Build, Own, Operate, Transfer). The energy centre comprises four coal-fired steam boilers with a total capacity of 30MWth and a steam reticulation system. Energy in the form of steam and hot water are supplied to ODHB, Cadburys, the University of Otago, NZTS and a number of smaller customers. Following acquisition of the Energy Centre, Energy for Industry carried out an extensive upgrade programme to extend the life of the plant and bring it up to modern best practice standards.
