US solar developer Renewvia Energy will commission three solar and battery-powered micro-grids on islands in Lake Victoria over the next six months, providing power for around 4,000 homes and businesses. A system on Ringiti island in Homa Bay is likely to begin operating this month and another on Ndeda island in Siaya county in May. The final grid on Mahanga island, also in Siaya county, will come online around July.
