Solar Highways Pilot Project

US 101 E. Dunne Ave and Tennant Ave Interchanges

CalTrans and Republic Cloverleaf Solar LLC (Republic) are negotiating a long-term airspace development lease and revenue share operations agreement that would permit Republic to install and maintain photovoltaic (PV) solar power systems within several highway right-of-way (mostly highway interchanges) in Santa Clara County. Seven sites have been chosen including both the E. Dunne Ave and Tennant Ave interchanges. 
 
The proposed Solar Highways Pilot Project would result in the production of renewable power facilities on otherwise unleasable freeway right-of-way while establishing a new revenue source for the state. The purpose of the proposed Project is to develop up to seven PV solar power systems, ranging in size from approximately 5 to 15 acres, within operating State right of way in order to generate up to a total of 15 megawatts (MW) of power to be sold to an investor or municipal owned utility. The seven PV solar power system sites would generate approximately 22 million kilowatt hours (kWh) per year, enough renewable power to supply approximately 2,250 residential units and offset approximately 15,000 tons of carbon annually.
