Otago Polytechnic wood boiler options

The Otago Polytechnic (OP) in partnership with City Forest Ltd (CFL) and Dunedin City Council (DCC) received funding from EECA's Wood Energy Grant Scheme to investigate the opportunity of creating a locally owned and sourced wood fuel market.

A study, undertaken by Transitionz Group Ltd and Forest Environments Ltd, was separated into a demand (end user) and supply side (forest supply) for reporting purposes. Thus, three reports were produced according to the requirements of each partner. The DCC report clarifies the delivery prices and how this would translate to savings compared to existing fuel supply contracts. The OP report concentrates on retrofitting or converting their existing coal boiler system to wood biomass. The CFL report considers the potential to supply the city using waste timber remaining in the forest after annual harvesting. This report addresses demand requirements for OP.
