Some projects are already underway. Tunisia and Algeria are planning links under the Strait of Sicily to reach Italy and Spain, and plans to connect to Morocco with undersea high-voltage direct-current cables with 3.6GW capacity are being discussed. Greece and Egypt are in the final phase of an agreement for a submarine interconnector with 2GW capacity.
The consequences of such a large project require additional research given the knock-on effects on the global climate. Meanwhile, more modest undertakings could compensate for the energy deficit that would follow ending gas imports from Russia. The main reason for low implementation is the need for transmission networks to transport electricity from dam to consumer, such as the proposed Grand Inga scheme .
