A large-scale solar array project at the West Jefferson High School and Middle School facility in Madison County has proven economically successful enough for Jefferson Local School officials to approve an expansion of the energy program, The Madison Press reports. Columbus-based Solar Plant will begin installation of a rooftop solar array at Norwood Elementary this spring, the Columbus Messenger reports. The district's existing solar panel project is freestanding behind the athletic complex, but due to aesthetic considerations, the next project will be a smaller rooftop installation. Officials made the decision following a presentation outlining the energy cost savings and dividend payments that have occurred as a result of the program. From September 2012 to September 2013, for example, the average electricity cost per day dropped from $142.20 to $73.73.
