Covanta adds 30 MW to Hawaii biomass plant

Covanta Energy has completed a $302 million expansion of the H-POWER energy-from-waste facility in Honolulu, Hawaii, adding 900 tons to its daily municipal solid waste (MSW) capacity with the addition of a third boiler.

Construction of the expansion began during the end of 2009. Now capable of processing 3,000 tons of MSW per day, the plant generates up to 90 MW, or enough power to satisfy about 9 percent of Oahu’s needs. Previously, H-POWER produced about 57 MW.

Operating as Covanta Honolulu Resource Recovery Venture, the plant has been in service since 1990 and is owned by the city and county of Honolulu, which funded the expansion. Covanta Energy is the designer, builder and operator of the facility and with the expansion secured a new, 20-year operating agreement.

It’s expected that the expanded facility will offset the need import about one million barrels of oil. During its 22 years of operation, the facility has processed more than 13 million tons of waste, reduced the need for 15 million barrels of imported oil, saved 500 hundred acres of land otherwise used for landfills and recovered 450,000 tons of metals for recycling, according to Covanta Energy.
