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 30 MWt
Description of facility: 

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.

Projects completed include the installation of a baghouse to reduce particulate emissions, upgrades of the control system and boiler feedwater treatment, installation of new standby power plant to support the Energy Centre, and installation of a new steam pipeline to Cadburys.

Co-firing trials were carried out using DEC Boiler 2 which is a 6.8 MW unit designed for coal firing with 2 spreader stokers, a 2 section dumping grate, multicyclones and bag filters.
