A local public utility in Riverside, California transformed a 20-acre landfill into a resource for renewable energy. The 21,600 solar panel array produces over 7 MW of AC power for the local populous. Helping power over 1,600 homes in the area, this array is one of the largest municipal solar projects in the state of California. The system is estimated to offset more than 4 percent of the city’s power consumption, and it’s the initial phase of the city’s push towards having a 100 MW clean energy portfolio.
RBI Solar was responsible for designing, engineering and installing the ballasted ground mount system on the job site. The ballast blocks were fabricated at a local precaster and pre-assembled for on-site delivery. The steady delivery of the precast ballasts were able to reduce the amount of time allocated to labor and keep the project on schedule. The customer provided gravel rock bedding for the ballasts to increase their sliding coefficient.
One of New Jersey’s largest public utility companies tasked RBI Solar with designing and engineering a ballasted landfill solution for Parklands Landfill in Bordentown, NJ. The property is part of New Jersey’s Solar 4 All program; which aimed to bring 125 MW of renewable solar energy to the state. The Parklands landfill will generate over 10 megawatts of clean energy and help power over 1,500 homes in the surrounding area.
When people think of renewable energy and buried waste, they think of Massachusetts. Or at least they might, as the state has been active lately in helping municipalities build solar farms on landfills.
According to the Massachusetts Department of Environmental Protection (MassDEP), there are currently 39 solar-on-landfill projects permitted by the agency that will produce a total of more than 78 MW of energy. (There are also two wind projects generating 3.6 MW of energy.) Some of the projects are complete, and several are under construction.
Other states, such as California and New York, have built solar projects on landfills, but Massachusetts has been especially enthusiastic over the past few years. In 2010, the state approved what was reportedly the first post-closure use permit for solar for the 2 MW Greenfield Solar Field on a landfill in Greenfield, Mass. Read the rest of this entry »
