The electricity tariff consists of four components – energy costs paid to the generation companies, network costs and market support services fees paid to SP Group, as well as market administration and power system operation fees paid to the energy market company and power system operator.
The energy costs component is adjusted quarterly to reflect the 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.
