Tonga has signed a deal with a United Arab Emirates renewable energy company to build a solar plant on the island of Vava'u.
The plant to be built by the Abu Dhabi-based firm, Masdar, is expected to meet about 13 percent of Tonga's annual electricity needs.
Tonga's Energy Minister Lord Ma'afu says the project will mean reduced electricity prices and save 180,000 litres of diesel.
The project is financed by a grant from the Abu Dhabi Fund for Development.
