The Government of Tuvalu has commenced feasibility work on a series of floating solar and coastal micro-grid renewable energy systems, intended to reduce dependence on imported diesel and strengthen the resilience of power supply across the islands. The feasibility stage is supported by technical advisers and international development partners with expertise in renewable infrastructure in small island environments.
Tuvalu currently relies heavily on diesel generators for electricity generation, which is costly and vulnerable to supply chain disruptions. Rising fuel prices have placed pressure on household budgets, government operations and businesses. The move to diversify energy sources is seen as both an economic and environmental priority, particularly in the context of climate change and Tuvalu’s limited land space.
Floating solar is being examined as a practical alternative to land-based solar farms, given the scarcity of flat and available land on Funafuti. Early studies suggest that solar arrays on lagoon surfaces can produce reliable generation while avoiding land competition. However, detailed engineering assessments are needed to examine anchoring design, tidal conditions, storm resilience and maintenance requirements.
The micro-grid component of the project aims to improve energy access in outer island communities. Small-scale solar and battery systems can reduce the need for regular fuel deliveries and allow more stable power supply for schools, clinics, refrigeration and communication systems.
Community consultations are being carried out to ensure the systems are suited to local conditions and maintenance capabilities. Training will be incorporated into the implementation phase so that island technicians can manage basic servicing and fault response.
If the feasibility results are favourable, Tuvalu could move to staged implementation over the coming three to five years. The initiative aligns with national targets to increase renewable energy share and support climate adaptation measures.
