Italy · Terna Econnextion · requests at 31 August 2026

Puglia and Sicilia hold 43% of the queue. One municipality, Brindisi, has asked for 13.3 GW, more than 12 of Italy’s 20 regions.

Terna publishes every request to connect storage to the Italian transmission grid, by municipality, by technology and by how far along it is. 290 GW is asked for across 3,460 applications in 814 municipalities. Only 10.5 GW has reached a signed contract, the stage the decree of 8 September 2026 protects. The Italy page reads the same register as tables.

How far along the requests are

Terna sorts every request into five stages. Nearly all of the queue sits in the first four. The last stage, a signed contract, is the one the new rule leaves alone.

Solution issued, not yet acceptedSTMG issued: connection solution issued, not yet accepted by the applicant47.6 GW

The decree of 8 September 2026 ends first come, first served. Capacity is reserved only for a project that holds its permit, and connection solutions already issued lose effect within fifteen days of the regulator’s measures unless the works behind them are validated, authorised or built.

What changed since last month

The first comparison arrives with the October readTerna updates the register monthly and we read it on the 5th. From then on this section, and the “What changed” view of the map, show every municipality whose figure moved: capacity that arrived, capacity that moved between stages, and capacity that left.

What is not published, and why

Terna does not publish the applicant’s name, the size of a single request or the connection point. The decree orders them onto Terna’s Portale Terra; no date is set. The operating fleet by site is not published either, so no ratio of paper to built is drawn for Italy. Requests to the distribution grids are held by the distributors and are not in this register.

Totals are the figures Terna’s charts print; the municipality rows are Terna’s underlying export. Region boundaries from ISTAT. Nothing on this page is modelled. What you may do with it.
