The San Joaquin County Department of Public Works hosted a ribbon-cutting on Tuesday, May 30 for the Hazelton Corporation Yard Solar Carport Project at 1810 E. Hazelton Ave., Stockton. The 496-kilowatt solar photovoltaic system will provide enough power to offset 75 percent of the electricity consumed at this site. San Joaquin County has a 20-year solar power purchase agreement with NRG Energy, Inc. and anticipates energy cost savings of approximately $3 million over the life of the contract.
