The Master Plans have been developed during the period of unprecedented technological change. The last few years have seen remarkable and disruptive improvements in renewable energy (RE) technologies and battery storage. Further expected reductions in the costs of these technologies provide FSM with an opportunity to combine achievement of its environmental targets with ensuring that electricity production remains affordable. At the same time, FSM faces a significant challenge of delivering electricity to people living on outer islands.
