This paper reviews the development of the Electricity Corporation of New Zealand’s first gas turbine based cogeneration project, discusses the design work performed, the project implementation and provides lessons learnt for future projects.

The Project employs a TP&M FT4 TwinPac Gas Turbine Generator Set which has been relocated to Anchor Product’s dairy factory at Te Awamutu where it provides hot exhaust gas for a Heat Recovery Boiler which generates steam for use in the dairy factory processes and a steam turbine.

The gas generators were converted from liquid fuel to natural gas and the free turbines were overhauled. All auxiliaries were relocated and upgraded as required by the new operating regime or changes in legislation, and a new microprocessor based Control and Instrumentation system purchased. Plant design is such that the Heat Recovery Boiler can accept hot gas from only one gas turbine at a time while the second is available for peaking duty as required.
