The Tina River Hydro Project is planned to be completed in early 2028 and will provide about 70% of the annual electricity demand for Honiara, the capital city. At its core, the project includes a 5MW hydropower station, a 71.5-meter-high dam, access roads, transmission lines, and a powerhouse positioned 5.4 kilometers downstream from the dam.
Project officials reported that overall progress has reached 28%, highlighting that construction continues to advance according to plan. The project is regarded as a significant step toward strengthening the Solomon Islands’ domestic energy supply and reducing reliance on imported fuel. By developing renewable resources, the initiative is expected to enhance energy security and support long-term economic development.
The Tina River Hydro Project is being carried out with broad international cooperation. Support is being provided by the Solomon Islands Government, the World Bank, the Australian Government, the Asian Development Bank, Korea-EXIM Economic Development Cooperation Fund, the Abu Dhabi Fund for Development, and the Green Climate Fund. This collaborative effort reflects the shared commitment of multiple stakeholders to promote sustainable infrastructure and clean energy transition in the region.
The project is expected to bring significant benefits upon completion. It will not only supply most of Honiara’s electricity demand but also provide stable, renewable energy to help reduce costs associated with fossil fuel imports. The establishment of transmission lines and related infrastructure will improve grid stability and increase access to reliable electricity for households and businesses.
The arrival of the TBM represents an important step forward in moving the project from planning to full construction. Once tunneling begins, the pace of development is expected to accelerate, bringing the project closer to its goal of operational readiness by 2028.
The Tina River Hydro Project demonstrates the Solomon Islands’ progress in adopting renewable energy solutions. With support from international partners, the project aims to establish a sustainable energy foundation that will contribute to future growth, improve living standards, and strengthen resilience in the national power system.
