Small Scale Solar Project
The PUB Small-Scale Solar Project is a targeted renewable energy initiative designed to strengthen power reliability and sustainability across key government facilities in South Tarawa. The project involves the installation of rooftop solar photovoltaic (PV) hybrid systems with battery energy storage systems (BESS), intended to provide seamless and uninterrupted power supply to selected ministry offices. Originally planned to deliver a total capacity of around 180 kWac, the project supports PUB’s broader goals of expanding renewable energy generation, reducing carbon emissions, and improving energy security.
The project was successfully completed in November 2025 following a phased implementation approach that began in 2024. Initial installations were carried out at the PUB headquarters as a pilot to test system performance and reliability. After confirming the effectiveness of the system, PUB’s technical team expanded the initiative to additional government offices, demonstrating confidence in the technology and its operational benefits.
Solar PV systems have now been installed and commissioned at several key offices, including PUB, MCIA, MWYSSA, ECD, and the Ministry of Education (MOE). The combined installed capacity totals 192.76 kWp, exceeding the original target. These systems are fully operational and are already contributing to the daily electricity needs of the participating offices, while providing backup power during grid interruptions.
Overall, the Small-Scale Solar Project represents an important milestone in PUB’s transition toward cleaner and more resilient energy solutions. By reducing reliance on imported fuel, lowering long-term operating costs, and enhancing power reliability, the project delivers both economic and environmental benefits. PUB has expressed its appreciation to all partners and staff involved and reaffirmed its commitment to pursuing practical, sustainable energy initiatives that support Kiribati’s long-term development goals.
