Frequently Asked Questions
How do I make a complaint about my electricity service?
Contact your provider (usually Tonga Power Limited) first and ask for a reference number — most issues are resolved quickly at that level. If it remains unresolved, or involves a safety or regulatory concern, use our Contact page and select "Complaint" as the submission type.
How are electricity tariffs set in Tonga?
Under the Energy Act 2021, the Commission reviews and approves electricity tariffs, taking into account fuel costs, efficiency standards and affordability for consumers. Tariffs are reviewed regularly — for example, on a quarterly basis for movements in diesel prices.

The Energy Act 2021 is Tonga's first comprehensive energy law. Enacted 26 August 2021 and given Royal Assent on 22 November 2021, it established the Tonga Energy Commission and extended regulation beyond electricity to petroleum, gas and renewable energy.
Does the Commission regulate petroleum and gas too?

The Government of Tonga has committed to reaching 70% renewable electricity generation by 2030, a target the Commission supports through its regulatory work.
