Name of the Project
Tina river hydrodevelopment project (TRHDP).

Location
The proposed project is located on the Tina river, a tributary of the Ngalimbiu river, in north Guadalcanal, in the Solomon Islands.

Client
The TRHYDP is a national project of the Solomon Islands, managed by a dedicated project office under the Ministry of Mines, Energy and Rural Electrification (MMERE).

Project Description
The TRHDP is part of a broader initiative called Solomon Islands Sustainable Energy Project and aims to provide electricity for Honiara from indigenous renewable-energy sources to ensure more affordable and reliable energy options for the capital. The project comprises a 53-m-high dam at an elevation of about 123 m above sea level, and an estimated 30 river kilometres from the sea, a 3.3 km tunnel to a powerhouse and a tailrace at an elevation of 73 m above sea level.

The reservoir formed by the dam will extend about 2.6 km upstream and will have a surface area of about 0.28 km² at an elevation of 175 m above sea level.
Initially, the powerhouse will have three generator units, each with a capacity of 5 MW, allowing for a maximum discharge of about 18 m³/s and a minimum discharge of about 2.4 m³/s.

Two 33 kV, 22-km-long transmission lines, built on the access road are proposed to connect the TRHDP substation to the existing Solomon Islands Electricity

Authority electrical grid at a substation located at the Kukum Highway junction, which, in turn, will connect to the Lungga diesel power station.

The transmission line will be designed to be upgraded to 66 kV in the future.
