Municipal solid waste (garbage)

Refuse Derived Fuel (RDF) steam turbine generator

46 MW expanding to about 73 MW


The primary function of H-POWER (Honolulu Program of Waste Energy Recovery) is to reduce the volume of municipal solid waste on Oahu. The plant is capable of consuming 2,160 tons of garbage per day, reducing the volume of refuse that goes to the landfill by 90%. H-POWER, owned by the City & County of Honolulu, processes the garbage and burns it in furnaces to produce steam that drives a turbine generator. The electricity is sold to Hawaiian Electric and distributed to customers. H-POWER is currently expanding by adding a third boiler and other equipment which should bring its capacity to about 73 MW. Hawaiian Electric and H-POWER are negotiating a power purchase agreement which will go to the Hawaii Public Utilities Commission for review. Learn more about H-Power.
