  • Tuvalu Solar Electricity System

    Tuvalu Solar Electricity System

    The pacific island nation of Tuvalu is on track to achieving its goal of 100% renewables by 2030, with the recent commissioning of a 500 kW rooftop solar project and 2 MWh battery energy storage system in it's capital Funafuti.


    FAQs about Tuvalu Solar Electricity System

    What is the Tuvalu solar power project?

    The Government of Tuvalu worked with the e8 group to develop the Tuvalu Solar Power Project, which is a 40 kW grid-connected solar system that is intended to provide about 5% of Funafuti 's peak demand, and 3% of the Tuvalu Electricity Corporation's annual household consumption.

    How much energy does Tuvalu use a year?

    Like many Small Island Developing States (SIDS), Tuvalu has been heavily reliant on imported fuel for its diesel-based power generation system. Through this new FSPV system 174.2 megawatts per hour of electricity will be generated each year, meeting two percent of Funafuti's annual energy demand.

    What is a floating solar PV system in Tuvalu?

    From solar rooftops and the Off-grid sola-powered Capacitive Deionisation (CDI) systems to the pioneering floating solar PV with 100kW. innovative solutions like floating solar panels (a first for the PICs) and raised solar installations are being embraced in Tuvalu as the Pacific grapples with addressing the challenge of limited land space.

    How TEC is powering Tuvalu with renewable resources?

    TEC has set a vision of “Powering Tuvalu with Renewable Resources” and this align well with the Tuvalu Government set target of 100% renewable energy by 2025. All the islands of Tuvalu are on 24/7 power supply and the access rate is 100%. The outer islands are powered by hybrid solar PV system with diesel generator on standby.

    Where does Tuvalu electricity come from?

    Tuvalu's power has come from electricity generation facilities that use imported diesel brought in by ships. The Tuvalu Electricity Corporation (TEC) on the main island of Funafuti operates the large power station (2000 kW).

    Is Tuvalu A good place to invest in wind power?

    Beyond the solar farm, Tuvalu is also exploring wind energy opportunities. Preliminary assessments on several outer islands are underway to determine the feasibility of wind power. These efforts are part of a broader strategy to diversify Tuvalu's renewable energy sources, ensuring a stable and reliable electricity supply.
