Landfill gas to energy statistics

Here are some quick statistics on the number of landfill gas to energy plants by state. California has 77 operational plants, Illinois has 32, Texas has 27, and Colorado has 1.  Granted we have a much smaller population than all of these other states, but with over 30 landfills in the state of Colorado there should be more of these plants in operation.  The only landfill gas to energy plant in operation is located at the Lowery Landfill in Aurora.  The gas gathering system consists of 218 wells and collects LFG from both the Lowery Landfill and the Denver Arapahoe Disposal Site (DADS).  Between the two landfills, Lowery being closed and DADS still in operation, they collect enough gas to produce 3.2 megawatts of electricity.  This is enough electricity to power nearly 3,000 homes.  In April of last year, a new LFG to energy plant broke ground at the Larimer County Landfill, located in Fort Collins.  This plant is expected to produce 1.6 megawatts of electricity.  Both the Lowery Landfill/DADS and Larimer County Landfill have plant sized below the average size of simlilar plants in the United States, which is 3.4 megawatts.  The largest LFG to energy  plant is located in Puente Hills, CA and produces 50 megawatts.
