Windsor Energy company logo


Windsor Energy (formerly RCR Energy) has been responsible for designing, manufacturing and installing more biomass boiler capacity in New Zealand than any other company.

Windsor Energy is the leading New Zealand EPC contractor specialising in biomass and other sustainable fuel sources. They partner with some of the best-known global names in biomass combustion technology to offer a variety of biomass systems ranging from small light industrial units to the largest biomass process heat plants in Australasia.

Windsor are unique in New Zealand in being technology agnostic. They have assessed and accessed the best technology available from different providers for different bioenergy applications and can therefore recommend whatever is most appropriate for a client’s requirements rather than being limited to one solution. This flexibility extends to grate technology for burning the range of moisture content fuels and waste products that typically make up NZ requirements, a diverse range of fuel handling solutions for different materials, budgets and locations and comprehensive emission control solutions.   

Windsor Energy biomass boiler projects have been successfully delivered across the globe including NZ, Australia, South America and the UK. Windsor are as comfortable delivering large, bespoke turnkey projects (up to 80MW) as they are supplying small, containerised biomass solutions (>180kW) for schools and small industrial applications.

Windsor are specialists in all areas of biomass use, from fuel handling, combustion, dust and emissions control, ash management, existing boiler conversions and combustion tuning. Windsor has a full in-house engineering resource as well as an extensive aftermarket Service and Maintenance capability throughout New Zealand.
