Solar-generated electricity will power streetlights, toll collection equipment, plaza and maintenance facilities, variable message signs and the E-470 administrative headquarters. In all, the installation  will power about a third of the highway.
“This solar project illustrates the E-470 Public Highway Authority’s goal of long term sustainability,” says Randy Drennen, chair of the E-470 Board of Directors.
The project, which began in 2008, is expected to save $1 million in electricity costs over a 20-year period. It was financed by Adamas and constructed by Martifer Solar USA, who will provide maintenance for the installation.
