With a capital expansion programme of over SBD1 billion, Solomon Power strives to develop and implement its planned capital and infrastructure projects over the next five years that will support its mission to provide a safe, reliable and affordable supply of electricity to the Solomon Islands.
These development projects are funded internally and also financed from various sources such as under the World Bank’s Solomon Islands Sustainable Energy Project (SISEP) and ADB’s Provincial Renewable Energy Project (PREP), specifically earmarked for the Fiu River Hydropower project.
Current projects in progress or have recently been completed are as follows.
- Lungga Power Station Expansion
- Solomon Power HQ Refurbishment Project
- UAE/NZ Funded 1 MW Solar Farm Project
- Outstations Upgrade Project
- Buala Hydro Re-commissioning
- Feeder 12 relocation, Upgrade to Ranadi Substation and new Kola’a Ridge Substation
- Network extensions
- Hybrid Generation Systems in Seghe and Taro
- Solar Power Development Project
- 11. SOLOMON ISLANDS ELECTRICITY ACCESS AND RENEWABLE ENERGY EXPANSION (EAREEP) PROJECT (PHASE II)
- Lungga Power Station Expansion
Lungga power station is SP’s main power station generating and supplying electricity to Honiara and environs. The Power plant’s installed generating capacity as at December 2014 was only 17 MW. However with the unreliability of generation coupled but with an escalating demand for power, SP has invested in the construction of a new station with an installed capacity of 10MW. The project was completed by MAN diesel for over SBD120m. The new station has been commissioned and is currently in operation.

The remodeling work provides an open workspace that promotes more interaction between staff at all levels. A drive through window where customers can pay for their cash power tokens was introduced to reduce queues and at the same time improve customer services. Under phase I as well, a pilot project funded by JICA for introduction of grid-connected PV generation totaling 50 kW was mounted on the car garage and fed directly into the grid supplying the office.
Phase II of the project, which included landscaping and upgrading of the car park area with designated parking spaces for customers and staff with an improved site access and drainage system. The works were carried out by Humphrey Engineering and completed in May 2016.
Phase II in progress
Phase III, involved improvements to the Stores and Distribution workshop, additional office space for Engineering and Planning including the construction of a Meter Testing Room. MP Construction executed the works under a contract. This phase was completed and commissioned end August 2017.
3. UAE/NZ Funded 1MW Solar Farm project.
Going forward, SP is investing in clean and renewable energy sources. Following the 2013 feasibility study investigating the development of a 1MW grid-connected solar power station, UAE and NZ government cofounded the development of a 1MW solar farm project at Fighter 1, Henderson.
The plant will save SP approximately US$880k per annum in diesel cost and help reduce the cost of electricity. The project was completed and commissioned on the 10th May 2016.

4. Outstations Upgrade Project
The principal aim of the Outstation Generation Project is for the supply and installation of new generators in selected outstations to upgrade and improve the current generation capability and reliability which will allow future growth demands in the provinces to be met. On top of that a new power station was built in Gizo and the existing Noro station refurbished and upgraded to meet industry standards.
Northpower of New Zealand was awarded the contract to supply the Generators for the selected outstations. The generators were tested and configured in Honiara and shipped out to the provinces in 2016.
a. Gizo power station upgrade project.
This project involves the construction of a new power station on the existing site and the supply and installation of 3 new 500KW generators, associated switchgear and transformers. The power station works was carried out by Hatanga Ltd and completed in June 2016. All the three generators and associated transformers and switchgear have been commissioned.
