Italian TSO, Terna SpA, has granted six of Hexicon’s seven wind power sites connection to the national grid. The six sites encompass a total combined capacity of 7,100 MW. Permit for the remaining site is still in process.

Hexicon, operating in Italy through its joint venture AvenHexicon, now has a portfolio of seven development sites for floating wind along the coasts of Sardinia, Sicily and Puglia. Grid connections were applied for in 2022 and Terna has now issued the technical solution to connect six of the seven locations to the national grid - a total combined capacity of 7,100 MW.

The interconnection permit, also called STMG, is a preliminary agreement from Terna to provide interconnection capacity. It provides a commitment from the TSO to make the necessary capacity available to be connected to the grid and is a mandatory step to receive the main authorization (the so called “Autorizzazione Unica” or “AU”) to build and operate an offshore wind farm.

The grid connection solutions are issued for six offshore wind farms under development off the coasts of Sardinia, Sicily and the mainland, in Puglia. The grid connection application for the remaining wind site is currently being processed and is expected to come through shortly.

“The progress is moving at record speed, which speaks for Italy's ambition to develop renewables in the country. Having the grid connection ready is yet another milestone passed, and one which significantly increases the value of each project,”,
said Alberto Dalla Rosa, CEO at AvenHexicon.
