Hawaiian Electric Company, Inc.'s (Hawaiian Electric's) East Oahu Switching project involved the installation of automation equipment for a key part of the utility's 46-kilovolt (kV) sub-transmission grid, coupled with a smart controller to automate switching in the event of a transmission outage in the area. The distribution automation entailed upgrades in eastern Oahu near Honolulu, with 8 of the company's 147 substations receiving new supervisory control and data acquisition (SCADA) equipment and communications links. SCADA equipment and a communications link were also installed on a 46 kV sub-transmission line switch that can restore power to 4 distribution substations in the project's service area.
