Three solid waste landfills in the US state of Massachusetts will go solar using GameChange racking’s innovative Ballasted Ground mounting system. The new power plants, which together will have a capacity of around 6.5 megawatts (MW) will be the latest addition to the company’s already extensive portfolio of solar-on-landfill and brownfield projects. GameChange’s Ballasted Ground mounting system has been used in 33 projects across 12 US states.
Andrew Worden, CEO of GameChange Racking stated: “Our patent pending Pour-in-Place™ Ballasted Ground System is rapidly gaining market share as the fastest installing and most cost effective solution for landfills, brownfields and rocky sites. The self-leveling technology is a key factor for installers to be able to level the racks while they are light prior to concrete install, which allows for speedy site completion.”
