Noninterconnected Island Systems: The Greek Case

Greece comprises more than 100 inhabited islands, 60 of which are not interconnected to the mainland grid, forming 32 isolated electrical systems, each with one or more islands interconnected to each other but not to the mainland. Noninterconnected island power systems (NIPSs) are located mostly in the Aegean Sea (Figure 1), host 15% of the Greek population, and account for almost 10% of the total national annual electricity consumption.
