Cyrénée is the project for the pipeline connecting Galsi to Corsica with 220km offshore and 230km onshore between Bastia and Ajaccio. A public consultation took place in 2010. The feasibility studies have sketched out a draft route. They have been put on hold in relation with the uncertainties around the Galsi project.

7.5.3 AN ACCESS TO THE ITALIAN AND EUROPEAN GAS NETWORK FOR SARDINIA, CORSE AND ELBA ISLANDS Infrastrutture Trasporto Gas (ITG) evaluated various alternatives to be applied in case the Galsi project should have a undefined postponement, whilst considering the Cyrénée and GALSI routes and minimising technical complexities (such as high depth sea and long off-shore routes) and costs, in line with cost-effectiveness and efficiency principles. The best option identified by ITG for the above scenario consists in two pipelines connecting Piombino (in the Tuscany region, center of Italy) to the islands of Elba and Corse (at Bastia); this project would create the presuppositions for the realization of the other infrastructures necessary to provide the islands with gas (that are the transmission and distribution systems onshore these islands and an off-shore connection between Sardinia and Corse).

A compression station should be installed at the entry site in Piombino. The whole project, including batch 3, has some regulatory, permit- ting and financial complexities and will require the involvement of other TSOs and the coordination between European regulatory authorities, such as the French and Italian NRAs. Identified complexities, however, do not affect the project's attrac- tiveness, given the reciprocal benefits that its implementation could bring to the involved countries; such benefits are expected to encourage these countries to cooperate for a shared network realization. The realization of the above projects of section 7.5.2 and 7.5.3 and other needed infrastructures in Corse and in Sardinia will make natural gas available for the local populations and indus- tries. This will bring the following benefits: \\ improvement of the energy mix (using natural gas instead of oil, LPG and diesel fuels brings a relevant cost reduction); \\ reduction of CO ² emissions.
