The Pacific Renewable Energy Investment Facility (PREIF) will administer a grant from the Asian Development Bank (ADB) for Tuvalu: Increasing Access to Renewable Energy (the project). The project will include subprojects on Nukulaelae, Nukufetau, Nui and Funafuti to continue the PREIF’s aim of transitioning electricity generation from diesel to sustainable renewable energy generation sources. Hybrid power systems were installed on Nukulaelae, Nukufetau and Nui in 2015 via a European Union (EU) funded project. The subprojects identified as part of this project will expand the existing hybrid power stations by installing additional solar capacity, thereby increasing the renewable energy contribution from approximately 60 - 70% to more than 90%. The subprojects will also increase flood resilience by replacing the existing diesel powerhouse on Nukulaelae and upgrading distribution system pillar boxes on all outer islands as well as improving power system monitoring and communication. The subprojects on Funafuti will install additional solar and a new battery energy storage system (BESS) to increase the renewable energy contribution. The renewable energy contribution is expected to increase from approximately 16% to 32% as a result of these subprojects. The Funafuti subprojects also include a control system to better manage power system and allow greater renewable energy penetration as well as improved communications between distributed generation sources. The subprojects will assist Tuvalu meet the objectives of its National Energy Policy (2009) as well as its goal of achieving 100% renewable energy by 2025 as articulated in the "Enetise Tutumau" - the Master Plan for Renewable Electricity and Energy Efficiency in Tuvalu. Implementation arrangements. The Ministry of Finance (MOF) will be the executing agency for the project and the Tuvalu Electricity Corporation (TEC) will be the implementing agency reporting to the Ministry of Transport, Energy and Tourism(MTET).
