Maldives - Sustainable Energy Development for the outer islands
Maldives has 194 inhabited islands, each of which is electrified with its own diesel-powered mini grid system (total installed diesel generation capacity of 100 MW + 100 MW on the tourism islands). In 2012, the cost of diesel power required government subsidies of more than 40 million US$.
On the other hand, Maldives has significant renewable energy resources, particularly solar and - to a minor extent - wind energy. Given the cost of diesel, the Government initiated two programmes to extend the use of renewable energies in electricity generation. The present project covers the design, tendering, and implementation of hybrid solar / battery / diesel mini-grids on 166 islands, with a total of 25 MW solar (PV) power, a total of 8 MWh storage capacity and 44 diesel power plants. Systems are roof-top or ground-mounted and have a size of between 3.5 kW and 1,600 kW per system.
