Terna Urges Italy to Prioritise Grid Integration Over New Renewable Capacity
Italy's transmission system operator says the country must shift focus from building renewables to connecting them, as grid queues and power prices strain the system.
Italy's grid operator Terna on Wednesday (2026-08-26) called for the country's energy policy to shift from building new renewable capacity to integrating existing and pipeline projects into a functioning system, Montel reported. The statement comes as Italy's grid already holds 350 gigawatts of connection applications, a backlog that dwarfs anything the current network can absorb.8,2
The call coincides with a parallel push from analysts. Earlier this month (week of 2026-08-17), analysts told Montel that Italy should declare a national emergency and reclaim control over its decentralised power system as a way of curbing soaring electricity prices. The political appetite for that prescription is unclear, but both arguments share a core observation: Italy's grid governance has not kept pace with the volume of clean energy projects seeking connection.7
Italy's regulator Arera added a pricing dimension in July. On Tuesday (2026-07-14), Arera said Italy should adopt zonal electricity pricing by 2030 to align with the rest of Europe, executing a plan that became law several years ago but remains unimplemented. Zonal pricing would vary power costs by area based on local supply and demand, in theory reducing congestion and sharpening incentives for investment in constrained regions.6
Terna has already committed substantial capital to solve the problem from the transmission side. The operator's €18 billion investment plan for 2024 to 2028 is one of the largest grid programmes in Italian history, the Economist reported. Still, Italy's connection queue of 350 GW runs far beyond what any single capital plan can resolve.2
The scale problem extends across Europe. ENTSO-E, the pan-European grid regulator, estimates that meeting EU electrification targets by 2050 will require €800 billion of grid investment. France's RTE has pencilled in €100 billion through 2040. TenneT, covering the Netherlands and much of Germany, is targeting €200 billion by 2034. The scale of commitment is clear; the pace of execution is not.2
Private capital is moving in regardless. In late May (2026-05-27), Qualitas Energy announced financing for a 211-megawatt battery storage portfolio in Lombardy and Apulia, partnering with developer ACL Energy. In late June (2026-06-24), NatPower and Tesla signed a multi-year agreement to deploy more than 25 gigawatt-hours of battery storage across Italy and the United Kingdom, with ambitions to scale beyond 100 GWh. NatPower estimated the combined construction value at $4 billion to $5 billion, with projected revenues above $15 billion over a 20-year period.3,5
Battery storage is the most visible integration tool available right now. It absorbs surplus renewable output and releases it during low-generation periods. But 25 GWh of new capacity, however welcome, does not fix the north-south congestion that divides Italy's grid, a structural problem that requires new transmission infrastructure and, eventually, workable zonal pricing.6,5
On the financing side, the European Commission on Thursday (2026-05-28) urged member states to redirect up to €20 billion from the Just Transition Fund to address the energy crisis. The JTF was designed to cushion fossil-fuel-dependent communities through industrial change; repurposing it for grid integration carries political complications in the communities where it was originally targeted.4
A further complication surfaced earlier this year. A suspected sabotage attack on the Transalpine crude oil pipeline in Italy in May (2026-05-18) prompted warnings about the vulnerability of European energy infrastructure. Terna confirmed at the time that the origin of the damage remained unknown. Physical security of transmission assets now runs alongside the integration agenda, not separate from it.1
The concrete test for Terna's push is the zonal pricing shift Arera has set for 2030. Cheaper power for consumers in constrained southern zones may conflict with generation interests in Italy's north. That political redistribution fight is what's most likely to slow the system's integration — not the engineering.6,7
