Officials at the Rincon del Diablo Municipal Water District on Thursday formally unveiled plans to build a solar canopy array and battery energy storage project at the Harmony Grove Village Water Reclamation Facility in Escondido. The reclamation facility runs up a power bill of about $5,000 each month and the solar-plus-battery project will help offset the wastewater treatment center’s energy costs. … The 302-kilowatt solar array with 559 panels atop a canopy will generate electricity to help run the treatment facility that recycles more than 180,000 gallons of wastewater on a daily basis.
