The wonderful Lelepa island, part of the Roi Mata’s Domain and a UNESCO World Heritage Site, is interesting not only in its culturally important role, but also in its development potential. As part of the Prove of Concept project (POC), the project team was able to carry out an initial infrastructure test with its innovative swarm technology and equip five buildings on the island with solar power based on a Flex-Grid1 meter based mini-grid.
