Italy Permit Reform Could Cut Spot Power Prices by a Third as Gas Dependency Widens Gap With Spain
Gas sets Italy's marginal electricity price in 89% of hours, and analysts say clearing the permit backlog is the fastest route to changing that.
Clearing Italy's backlog of stalled renewable energy permits could cut spot power prices by up to a third, analysts and industry participants told Montel, in a country where gas-fired generation sets the wholesale electricity price in 89% of hours. The estimate came from Diego Begnozzi, analyst at Italian think tank Teha. "A much stronger reliance on renewables could lower prices across the whole system," he said. "We calculated that the discount could amount to as much as a third."3,6
The scale of Italy's exposure to gas prices is sharpest against Spain. Ember calculated that gas set the Italian day-ahead price in 89% of hours during the first months of 2026 — against just 15% in Spain. Italy's average day-ahead power price reached €142/MWh in March 2026; Spain averaged €59/MWh over the same month, the Economist reported on 19 May 2026. The two countries operate the same market design. The divergence comes from generation mix.3
A faster rollout of Italian wind capacity could deliver most of the potential price reduction on its own. An analyst told Montel late on Monday 15 June 2026 that accelerating wind deployment could cut Italian power prices by more than 20% by reducing the country's reliance on expensive imported fossil fuels.6
The European Commission cleared a €23bn ($26.5bn) state aid scheme for Italian renewables on 9 June 2026 under the Clean Industrial Deal State Aid Framework.4 State aid authorization and permitting are separate tracks, though. Projects can win EU funding approval and still sit in a construction permit queue; analysts identify the permitting bottleneck, not the aid structure, as the binding constraint on the build-out.4
Experts told Montel during the week of 8 June 2026 that nuclear power could push down Italian wholesale prices over the long term by displacing gas as the price-setting fuel, bringing Italy toward French price levels.5 Italy has no operating nuclear capacity, and any new build would take well over a decade. Renewables remain the only credible nearer-term mechanism for shifting the merit order.5
The Iran conflict has raised the cost of Italy's dependence. Analysts told Montel on Thursday 21 May 2026 that Italy's spot power price could reach EUR 320/MWh — more than double the levels prevailing at that time — should the conflict push gas prices sharply higher alongside cold weather.1 ICE Endex TTF front-month gas was trading at €75.83/MWh on 9 September 2026, maintaining pressure on Italian generation economics.
Saharan dust events add episodic volatility on top of the structural exposure. Analysts told Montel on Friday 15 May 2026 that such events could cut solar generation by up to a quarter in Italy, adding EUR 4-15/MWh to day-ahead prices.2 In severe scenarios involving added cloud cover, the output loss could exceed 20% — equivalent to 40-50 GWh per day, according to Paolo Guerrieri, energy economist at the Paris School of International Affairs, speaking to Montel.2
The analyst estimates for potential relief span a range. Faster wind alone may deliver 20% price reductions; a broader clearing of the renewable permit backlog reaches up to a third. The upper bound assumes sustained administrative progress, not the incremental clearances that have characterized the Italian permitting system historically.6,4
With ICE Endex TTF front-month gas at €75.83/MWh on 9 September 2026 and gas still setting prices in roughly nine out of ten Italian power auctions, Italy's structural premium over Spain is not narrowing. Monthly permit approvals for wind and solar projects — rather than headline aid commitments — are the operational figure traders have least visibility on and the one most likely to move Italy's gas-dependency ratio before the next peak demand season.6,4
