groSolar to Install 6,500 Solar Panels on Capped Landfill

Logan Township, Gloucester County, NJ - February 24, 2011 – National solar integrator, groSolar, is helping Clean Harbors Environmental Services, Inc., utilize solar powered electricity for its United States Environmental Protection Agency (USEPA) and State of New Jersey approved pump and treat system to decontaminate groundwater at an ongoing environmental clean-up project it has been conducting in New Jersey.

“We’re using sustainable green power from a 1.5 megawatt solar array to create clean groundwater. The photovoltaic modules sit on top of a capped landfill that was closed decades ago,” said Bill Geary, President, Clean Harbors Development, LLC. “At Clean Harbors, we are in the business of protecting the environment. This project demonstrates our commitment to sustainability by redeveloping an otherwise unusable Brownfield to generate renewable clean energy to power ongoing decontamination activities at the site. This is the very type of Innovative Green Energy Project the USEPA and State of New Jersey are advocating from business and industry.”

Upon completion of the project in the spring, the groSolar installation is expected to lower annual electric costs at the site by more than 90 percent.

“After deciding to install solar last year, we went through a formal procurement process and hired independent experts to conduct a Request for Proposal (RFP) process to evaluate several, qualified providers of integrated solar energy solutions. We selected groSolar because of its outstanding reputation in the commercial solar industry, broad capabilities, strong knowledge of landfill construction, and turnkey approach,” said Geary.

Clean Harbors (NYSE: CLH) is funding the project internally. However, the project is receiving the benefit of federal tax credits and New Jersey SRECs, which will accelerate the company’s return on investment (ROI).

“Our landfill experience provided Clean Harbors with the extra assurance they needed on this project. The New Jersey renewable portfolio standard (RPS) is providing them with additional cash flow to support the ongoing clean-up project to generate revenue as well as clean power, which benefits large commercial facilities, such as Clean Harbors,” says Jeff Wolfe, CEO, groSolar.
