Large electricity tariff reduction from July 1

Nuku'alofa, Tonga

Electricity Tariff Reduction effective 1st July 2020
$0.6102 per kilowatt-hour

Diesel prices continue to drop from $1.5091 per litre in March 2020 to $1.0419 per litre in June 2020 (an accumulated reduction of $0.47 per litre or 32% reduction in total)1,

The accumulated price reduction from 15 March 2020 to 15 June is driven mainly by the ongoing and current economic impact of the worldwide COVID-19 pandemic.

Therefore, the new published rate for electricity will be reduced by a total of $0.1198 per kWh (16.4% reduction) per kWh to $0.6102 per kWh from the current tariff of $0.7300 per kWh set back on 1 April 2020.

The new price will last for 3 months unless otherwise reviewed. This is the lowest electricity price in 14 years.

The tariff set back in April 2020 $0.7300 per kWh, Government of Tonga (Shareholder) subsidised $0.08 kWh Lifeline Tariff (known as Government Policy Obligation or GPO), to all residential customers consuming 100 or less kWh of electricity per month.

The new electricity tariff of $0.6102 per kWh was approved by the Electricity Commission to be effective from 1st July 2020.

Since the new electricity price is less than $0.65 per kWh, there is no Lifeline-Tariff GPO effective from 1 July 2020.

The table set out below provide details of the new electricity tariff.

1.  One (1) litre diesel generates around 4.05 kWh of electricity.

The overall Power Generation from Renewable Energy (RE) Sources is only 12% to 14% of our total monthly power generation to which its impact on our prices is included on this tariff calculation.

The next electricity tariff review will be due by 1st October 2020.
