"Tina Hydro Project "

The Tina River Hydro Development Project (TRHDP) is a National project of Solomon Islands, managed by a dedicated Project Office under the Ministry of Mines, Energy and Rural Electrification, MMERE.

The proposed development is situated on the Tina River, a tributary of the Ngalimbiu River on north Guadalcanal. The Ngalimbiu flows to the Iron Bottom Sound about 15 kilo metres east of the capital Honiara.

The TRHDP is part of a broader initiative called Solomon Islands Sustainable Energy Project, SISEP, and has as its objective the provision of electricity for Honiara from indigenous renewable energy sources(hydro) to provide more affordable and reliable energy options to the capital.

The proposal is for a single power station with four Francis turbines, each with a capacity of 5 MW. Water will be captured by a Roller Compact Concrete (RCC) dam, approximately 50 metres high, and fed through a 3.3m diameter headrace tunnel, a distance of 3.5 kilo metres to the power house.

Power will be conveyed to the Lungga substation, on the eastern outskirts of Honiara (a distance of approximately 22 kilometres) by twin 33kV transmission lines.

The power station is expected to produce just over 80 GWh in an average hydrological year, which is about the equivalent of Honiara’s current demand. Because of the significant variation between inflows during the wet and dry seasons, there will still be the need for back up thermal generation. Read more about Proposal

Who we are

The project is managed by the TRHDP office under the Ministry of Mines, Energy and Rural Electrification (MMERE) of the Solomon Islands Government. The project is currently working with the five tribes identified by a traditional land identification process to acquire about 550 ha. This has resulted from feasibility studies financed by the World Bank (WB) (with AusAID financing through the Pacific Regional Infrastructure Fund, PRIF). And the European Investment Bank (EIB) and Pacific Islands Greenhouse Gas Abatement through Renewable Energy Project (PIGGAREP) working within the South Pacific Environment Program, SPREP. The International Finance Corporation (IFC) is a potential partner. Read more about Who we are
