The HVDC Italy-Corsica-Sardinia (also called SACOI; Sardinia-Corsica-Italy) is used for the exchange of electric energy between Italy, Corsica and Sardinia.
First used in 1965 as mono-polar line, today this takes the form of a bi-polar high voltage direct current (HVDC) line. It consists of three overhead line sections: one on the Italian mainland with a length of 50 kilometers, one on Corsica with a length of 167 kilometers and one on Sardinia with a length of 87 kilometers. In addition to this, there are two submarine cable sections: 103 kilometers (between Italy and Corsica) and 15 kilometers (between Sardinia and Corsica).
Static inverters for this line, which can transfer a maximum power of 200MW at a voltage of 200kV are in use today. Until the 1990s mercury vapor rectifiers were used, which have now been replaced by thyristors. In 1992 a second pole was taken in service, which can transfer 300MW at a voltage of 200kV. In contrast to most other installations for high voltage direct current transmission this system is a multipoint system making thus possible the energy exchange between several static inverter stations.
