Water services According to their data, while 88.5% of the world has access to water, only 52.6% of the people of the Pacific Islands have access to water, with Papua New Guinea, Solomon Islands and Timor-Leste having the poorest access, while seven of the countries including Tonga, have almost universal access to water services, where more than 95% of the poulation can have access to safe water services.
Electricity services With electricity, in some regions of the Pacific only 33% of the people have access to electricity, comparing with 87.4% of the world.
Once again the development is uneven and in eight of the countries, including Tonga, some 90 percent of households have access to electricity, while the overall average for the 15 countries is 75%.
Meanwhile, an average of 69% of the population in 15 Pacific countries have access to improved sanitation.
Unlike access to improved water sources, access to sanitation service varies realty across countries.
Over 95% of electricity in Tonga was generated using imported diesel fuel.
Outer island renewable energy investments are guided by Tonga Energy Road Map (TERM) 2010–2020.
The first phase of TERM (2014–2019) involves (i) installing solar power systems, including some smart meters on nine outer islands; (ii) transferring operation and maintenance knowledge, and (iii) rehabilitating the existing grid network near the solar power generation systems on the islands of ‘Eua and Vava’u.
By 2030, 70% of all electricity is targeted to be generated from renewables.
The government and TPL have no plan to install any new diesel generators after 2020.
