GRICUA is continually working to upgrade and maintain the power delivery system. The most recent job is the Transmission System Hardening Project. GRICUA’s engineering staff analyzed the area’s most likely to be damaged during monsoon storms and designed a project where every 3rd or 4th existing pole is replaced with a new pole that is designed to withstand winds up to 100 miles per hour. This project will help prevent cascading line damage during the most severe monsoon storms. Work is complete on the transmission line to the Santan substation. Crews will now be working on this project along Casa Blanca Rd. Please drive with extra caution in this area.
