Italy legislates a nuclear return from the 2030s as war recasts EU energy security

Italy legislates a nuclear return from the 2030s as war recasts EU energy security Rome's enabling law, which its energy minister ties to wartime supply fears, marks a European shift on nuclear even as financing stays the hard part. Italy's energy minister Gilberto Pichetto Fratin said on Tuesday (2026-05-19) that the war in the Middle East is forcing the EU to rethink nuclear power, the clearest official signal yet behind Rome's move to legislate a return to atomic generation from the 2030s.¹ That matters because the rethink is being driven by security, not decarbonisation math. "Four or five years ago," the minister noted, the debate looked different. A legal framework that reopens the door is less a near-term supply event than a marker of how far the argument has moved.¹ Italy is not moving alone. The European Commission has forecast that nuclear capacity across the bloc would rise from 100GW to as much as 145GW by 2050, a path that depends on member states like Italy actually building.³ The economics are the hard part. Britain offers the cautionary tale: its government moved to proceed with Sizewell C, two giant reactors that could cost over £38bn ($51bn). For one British reactor already under construction, the developer reckons some 60% of the final cost will be financing rather than steel and concrete.^3,4 That is why the structure matters more than the ambition. Britain's parliament passed legislation on 31 March (2026-03-31) allowing a regulated asset base model for Sizewell C, shifting construction-period financing risk onto consumers and away from developers. Italy's enabling law will face the same question of who carries a decade of cost before a single megawatt-hour is sold.⁴ For traders the signal is long-dated. New nuclear on Italian soil would not displace gas-fired generation until the 2030s at the earliest, and the standardised small modular reactors some see filling the gap are not expected before the early 2030s even on their boosters' timelines.⁵ The more pressing pressure on Italian power economics is current, not in the 2030s. Italy's energy regulator has begun work on a mechanism to compensate gas-fired plants facing high costs, pending European Commission approval, a scheme that would cover part of generators' net costs.² The juxtaposition is telling. Rome is legislating for nuclear generation from the 2030s while moving to keep gas plants solvent under current cost pressure.² Analysts have warned Italy to target state aid at the energy-cost shock from the Iran war and align with EU policy rather than lean on Brussels for intervention.⁶ The wider picture gives the policy room to run. Barclays predicts net nuclear capacity outside China and Russia will rise by more than half between 2030 and 2050, to over 450GW, with SMRs accounting for 40-60% of the total and implying a $1trn market. Whether Italy captures any of that depends on execution, not enabling laws.³ What to watch is the financing model attached to Italy's framework when it emerges, and whether the Commission signs off on the gas-plant compensation scheme keeping the current system solvent. The legislation buys optionality. It does not yet move a single forward curve, and the wartime security case that justifies it could fade as fast as it arrived.^2,4
