The electricity tariff consists of the following four components: a) Energy costs (paid to the generation companies): This component is adjusted quarterly to reflect changes in the cost of fuel and power generation. The fuel cost is the cost of imported natural gas, which is tied to oil prices by commercial contracts. The cost of power generation covers mainly the costs of operating the power stations, such as the manpower and maintenance costs, as well as the capital cost of the stations. b) Network costs (paid to SP PowerAssets): This fee is reviewed annually. This is to recover the cost of transporting electricity through the power grid. c) Market Support Services Fee (paid to SP Services): This fee is reviewed annually. This is to recover the costs of billing and meter reading, data management, retail market systems as well as for market development initiatives. d) Market Administration and Power System Operation Fee (paid to Energy Market Company and Power System Operator): This fee is reviewed annually to recover the costs of operating the electricity wholesale market and power system.
