This document is a conceptual design proposal for diversifying the power supply of the Chiller AjYad facility. It involves joining some existing power feeders from the ShamIya-2 and Haram-2 substations to provide more reliable power. Feeders AH06 and AH26 would be joined at MV3 substation, and feeders AH02 and AH06 would be joined at Chiller AjYad/Haram Two. This would merge the feeder routes and supply power to Chiller AjYad from both substations after the joints.
