What is the power system of the island?

The overall situation of island's power system is somewhat unique among the islands studied in this paper. The island has a modern 87 MW combined cycle gas turbine (CCGT) plant, using LNG. This provides low cost generation on the island that is also competitive on the UK power market .

What is the most adapted electricity source for the French islands?

As previously underlined, diesel engines are the most adapted electricity sources for the islands due to their small nominal power and relative high ramp rate. The high contribution of fuel in the French islands is presented in Fig. 2 for 2016 [ [8], [9], [10], [11], [12] ].

How has the French government regulated Ocean Energy Systems?

The French Government has initiated legislation and regulation simplifications for Ocean Energy Systems over several years in order to facilitate their development and consolidate their funding. For instance, Decree No. 2016-9 of January 8, 2016, allows the obtaining of a license to occupy the maritime public domain for up to 40 years.

Should Islands be connected to mainland power systems?

At the cost of an often very significant capital investment, connecting islands to mainland power systems can significantly reduce the costs of electricity supply. Several techno-economic analyses have investigated relatively positive cases for interconnection, e.g. for several Greek islands and for Malta , .

Are island power systems underutilised?

As considered above, island power systems are typically characterised by a high ratio of total installed capacity over peak load and a low capacity factor as noted in Section 4.2. The consequence of this is a relatively underutilised generation system.

Why do Island power systems have low capacity compared to mainland power systems?

All island power systems will show relatively low capacity factors compared to mainland plant since islands must have a high level of reserve to ensure system security in the absence of integration into a wider power network.
