Electricity Tariff effective from 1 July 2025
The Competent Authority with its ADO Fuel Price for quarter April-June 2025 driven by a decrease in diesel prices of $0.23 per litre (10.72%). Therefore, the Energy Commission has approved the new electricity tariff effective 1st July, 2025. Thus, the revised power tariff for this quarter, will be set at $0.8494 per kilowatt-hour (kWh), representing a decrease of 13.1% from the previous quarter’s rate of $0.9778. The decrease can be attributed to the decrease of diesel prices, which decreases by 10.72% during the April to June 2025 quarter.
The new electricity tariff to adopt by Tonga Power Limited is $0.8494 per kilowatt-hour and will be reviewed on a quarterly basis with respect to the movement in diesel prices and on an annual basis according to the movements in inflation.
The overall Power Generation from Renewable Energy (RE) Sources is averaged from 22% of TPL total monthly power generation to which its impact on their prices is included on this tariff calculation.
Tonga Power Limited will now cover the cost previously funded by Government under the GPO (Government Policy Obligation) for customers consuming less than 150 kWh per month, which is 70 seniti kWh.
The revised tariff rates approved by the Energy Commission are as follows:
Note: The Electricity Tariff is regulated by the Energy Act 2021 and administered by the Energy Commission. A process set down in the Concession Agreement between Tonga Power Limited and the Energy Commission determines the tariff adjustment.
The Competent Authority is the Tongan Government Agency that sets the landed price of diesel which Tonga Power Limited uses for its power generation.
Respectfully, Tonga Energy Commission
