Transmission, Distribution & Supply

After electricity is produced at the various power plants it has to reach the customers that use the electricity. High voltage transmission lines carry electricity long distances to a substation. The power lines go into substations near businesses, factories and homes. Here transformers change the very high voltage electricity back into lower voltage electricity. The Oman Electricity Transmission Company SAOC (”OETC”) is the monopoly provider of transmission services in the MIS and Dhofar Systems. OETC owns and operates the 220 kV, 132 kV and 400 kV interconnected transmission systems, and as system operator is responsible for the central dispatch of generating and desalination facilities connected to the MIS and Dhofar Systems.

While the transmission system delivers high-voltage electricity from generators to substations, the distribution system is the final stage in the delivery of electrical power. The distribution system reduces the transmission voltage and then delivers the electricity to retail customers. In addition to substations, the distribution system includes wires, poles, metering, billing, and related support systems involved in the retail side of electricity. Three licensed distribution and supply companies (the Muscat, Majan and Mazoon Discos) in the MIS and the Dhofar Power Company (DPC) in the south have monopoly rights to carry out these functions and distribute and supply electricity within Authorised Areas stipulated in their licenses.
