The Malta–Sicily interconnector is the submarine power cable which connects the power grid of Malta with the Italian Transmission Network managed by Terna, which is part of the European grid.

Technical Characteristics[edit]

The 95-kilometre (59 mi) long subsea cable starts at Magħtab, Qalet Marku in Malta and it runs to Marina di Ragusa in Sicily, Italy. [1] From there it is connected to the Ragusa substation via 25 kilometres (16 mi) underground cable.[2]

The cable and 132/220 kV substation in Malta is provided by Nexans. The cable has capacity of 225 MW [3] and it uses 220 kV high voltage alternating current. The interconnector will be operated by Enemalta, the Maltese power corporation. The interconector was operational in April 2015 with a commercial capacity of 200 MW.[4][5] In the 2014 the cable was laid in the sea by the ship C/S Nexans Skagerrak of the Company Nexans.[2]

The project is to cost €182 million.[6]

The benefits of the interconnector[edit]

The cable will allow the island to exchange electricity with the Italian power market, i.e. the island can both import and export electricity from in Italy through the interconnector. It allowed Malta to end its previous electricity's isolation and achieving a diversified mix of energy sources for the country. In February 2015 European Commission underlines in one of its communication that Malta's interconnection level will go from 0% now to approx. 35% with the new interconnector. [7]
