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] ].

Which islands have achieved complete energy self-sufficiency?

So far, only very small islands such as El Hierro in the Canary Islands have achieved complete energy self-sufficiency, says Dominique Grondin, who studies energy engineering at the University of La Réunion.

Are France's Islands self-sufficiency?

The challenge is greater for bigger islands, especially those with significant industrial activity, high standards of living and large numbers of people. Another of France’s island departments, Corsica, has similar energy self-sufficiency to Réunion, about 13%. The two islands share the same electricity grid operators.

Is Corsica more energy-independent than France?

Corsica is more than three times larger than Réunion but has a smaller population and lower levels of energy consumption. It’s also connected to the Italian power grid, whereas Réunion is “totally isolated”, Grondin says. Of France’s other island departments, New Caledonia is bottom of the energy-independence list, at just 3%.
