Los Angeles Utility Pursuing Power Production from Yard Waste

The Los Angeles Department of Power and Water (LADWP) announced last week that it plans to buy 40 megawatts of power from a new facility that will use anaerobic digestion to convert grass clippings and other yard waste into electricity. The L.A. Board of Water and Power Commissioners approved the power purchase agreement on December 2nd, but the L.A. City Council must also approve the agreement. Under the proposed agreement, LADWP will buy all the power from the facility, which will be built by BioConverter LLC by 2008. According to that company, the new facility will be more efficient than previous anaerobic digesters, producing 30 to 50 percent more energy from the same amount of biomass. The facility is expected to convert 3,000 tons of plant material into biogas each day, which will be used to produce about 333 million kilowatt-hours of electricity per year. See the LADWP press release.
