Tonga's high electricity tariffs will be reduced this month, returning to the mid-2007 level as the falling cost of diesel fuel is passed on to consumers.
Matangi Tonga online reports Tonga Power expects a further decrease in the electricity tariffs in April.
The company's Acting Chief Executive, David Wright, says electricity tariffs will decrease and will apply to electricity supplied after the date of the next meter readings in February.
However, a non-fuel component in the tariff has actually increased.
Mr Wright says normally, only the fuel component is reviewed, but this time the Electricity Commission has reviewed both the fuel component and the non-fuel component of the tariff to determine the new electricity tariff.
