The Tonga Energy Commission (TEC) is the Kingdom of Tonga's independent statutory regulator for the energy sector. TEC was established under the Energy Act 2021, which the Legislative Assembly enacted on 26 August 2021 and which received Royal Assent from His Majesty King Tupou VI on 22 November 2021.
The Act provides the first comprehensive legal framework for Tonga's energy sector, extending the Commission's regulatory mandate beyond electricity (previously governed by the Electricity Act 2007) to cover petroleum, gas and renewable energy as well. TEC's principal objective is to ensure a safe, continuous, secure and affordable supply of energy to all consumers in the Kingdom, while supporting Tonga's commitment to reach 70% renewable electricity generation by 2030.
