What the sockets look like
Power in Tonga
Tonga, a Polynesian kingdom located in the South Pacific, consists of 169 islands, of which 36 are inhabited. Tonga uses Type I power plugs. The standard voltage is 230 V and the supply frequency is 50 Hz. Power generation in Tonga is heavily reliant on diesel fuel, although there is a growing emphasis on renewable energy sources such as solar and wind power. The power grid's reliability is moderate, with occasional outages due to the country's remote location and vulnerability to extreme weather events. Efforts are underway to improve the infrastructure and increase the share of renewable energy in the national grid.
