Research and reports

The following findings are part of EECA’s quarterly consumer research that tracks the nation’s views on energy efficiency and renewable energy.

East Harbour Energy was commissioned by Fonterra to carry out an assessment of the feasibility of converting the energy supply at their Tuamarina, Kaikoura, and Culverden milk processing plants from diesel or LFO to wood fuel.

This report investigates the site requirements, the regional wood fuel supply, suitable boiler plant, consenting issues, risks, benefits, and provides a financial assessment of conversion.

This report investigates the options of converting two existing LPG boilers to other fuel sources.  It concludes that at this site, the best option is to install a new wood chip boiler and convert one of the existing boilers to run on recycled oil

This study looks at the feasibility of replacing light fuel oil boilers with wood fuel boilers at ENZAFOODS site in Nelson.  It found that the due to the variable steam demand at the site and the high cost of wood fired boilers per kilowatt, the most cost effective approach to steam supply at the Nelson site would involve utilising a relatively small woodfired boiler as a "Base Load" boiler.
