The City of Honolulu broke ground in December on the long-awaited expansion plans for Honolulu’s H-Power plant. The $302 million project will expand the waste-to-energy plant’s capacity by 50 percent to handle an added 300,000 tons of garbage a year at the Campbell Industrial Park facility. Processing capacity will increase to 900,000 tons at the 28-acre plant, which is owned by the City and County of Honolulu. That volume will be able to generate 84 megawatts of power, which represents about 6 percent of Oahu’s electricity needs.  The project will create approximately 300 construction jobs as well as additional jobs to operate and maintain the facility when it’s completed in two years. With Oahu residents generating about 1.5 million tons of garbage each year, the expanded capacity at H-Power will help reduce the tonnage sent to Oahu’s only landfill, Waimanalo Gulch.
