Measures
Reducing petroleum product dependency via transport efficiency strategies and power sector decarbonization
Tonga’s reliance on imported fuel is high, whereby 81 per cent of its primary energy supply in 2018 came from externally sourced oil products. The majority of petroleum products are used for power generation purposes (39 per cent) as well as in the transport sector (50 per cent). Being a Pacific Island State, all of Tonga’s petroleum products are imported. Hence, such high reliance on petroleum products makes Tonga susceptible to future supply and price shocks.
Rapid ramping up of renewable power generation allows a substantial decrease of petroleum product usage in the power sector. For example, a decrease in diesel usage ranging up to 14.6 kTOE can be achieved if the power sector is fully decarbonized, compared to the usage in 2018. Notwithstanding this, Tonga’s energy security can be further enhanced through transport efficiency measures. These are, for example, by introducing vehicle fuel economy standards and by electrifying part of the transport fleet.
