Italian energy diplomacy has spent the past few years pointing south toward North Africa. The projects moving fastest now point east, across the Adriatic toward the Balkans, and the reasoning has changed along with the direction.
The straightforward version is physical. Southeastern Europe is adding solar and wind capacity quickly and has limited storage and limited interconnection. Italy has demand, a grid that reaches it, and increasingly a need for flexible supply at the hours when its own solar output falls away. Two systems with complementary shapes and a short sea between them are an obvious pairing.
The less discussed version is commercial. Interconnection does not only move electricity, it moves price signals, and whoever is connected to a market first tends to shape how that market prices its exports for a long time afterwards. The countries in the region know this, which is why the negotiations have been slower than the engineering.
For Italy the projects also sit inside a broader industrial argument. Cable manufacturing, grid engineering, and offshore installation are sectors where Italian firms are genuinely competitive, and a corridor of interconnection projects is a domestic order book as much as it is a foreign policy.
The obstacle is permitting on both shores, which is where similar projects have historically lost their years. The current schedule assumes that consent runs in parallel on the Italian and the eastern side. That has not been true of any comparable project so far, and it is the assumption most worth watching.
