Italy Approves Nuclear Return Framework After Final Senate Vote

Key Facts

Italy's Senate approved a bill on September 23, 2026, establishing a route back to nuclear electricity generation, with 81 votes in favour, 51 against and 7 abstentions. The final parliamentary vote gives Giorgia Meloni's government authority to write rules for a sector dormant for nearly 40 years. Its policy centres on small and advanced modular reactors as tools to strengthen energy security and reduce industrial emissions. Parliament approved a legal framework; operating a reactor still requires implementing rules, permits and a viable project. The immediate development is therefore a regulatory opening for future investment, rather than new generating capacity on the grid. Its economic importance will depend on whether the government turns that authority into workable, sufficiently clear procedures.

The delegation covers rules for building and operating plants, managing spent fuel and radioactive waste, and supervising nuclear safety. Under the bill, the government has 12 months from the law's entry into force to issue the necessary legislative decrees. That deadline concerns detailed regulation, not the start of electricity generation or completion of a first plant. Approval of an individual project will also depend on site, environmental and safety requirements clarified through the subsequent rules. Separating the broad statute from project authorization is essential when estimating the time between a policy decision and a productive asset. Earlier clarity would let companies and lenders assess construction costs, obligations and execution risks with greater precision.

Italy's reliance on imported energy explains the government's interest in an additional domestic source of electricity. Overall energy import dependence stood at 75.8% in 2024, according to Italy's environmental research agency ISPRA. Dependence was much higher for individual fossil fuels: 95.8% for natural gas and 95.5% for oil and petroleum products that year. Italy also imports electricity generated at nuclear plants in neighbouring countries, including France. If domestic reactors eventually supply power that replaces imported-fuel generation, they could reduce demand for some foreign energy. Passing the law alone changes none of today's import volumes; that effect requires capacity to be built and operated.

The distinction between the total energy mix and the electricity mix matters when assessing the potential effect. In the International Energy Agency's 2021 review, natural gas supplied 42% of Italy's total energy and oil 33%, while renewables supplied 19%. Coal and other sources also contributed, so renewables did not account for everything left after gas and oil. Nuclear plants would first change how electricity is generated, then change fuel demand to the extent that their output displaces other generation. Oil use outside the power sector would not automatically fall because reactors joined the grid. Any later economic assessment should therefore identify the electricity and fuel that nuclear output actually replaces.

The government is focusing on small and advanced modular reactors to pursue both supply security and lower industrial emissions. A parliamentary review of the national energy plan describes a scenario in which nuclear power supplies about 11% of electricity demand in 2050. That is a long-term scenario, neither an approved volume of generation nor an outcome guaranteed by the Senate vote. Reaching it depends on technical rules, site selection, finance, construction schedules and local acceptance of projects. For industry, nuclear power's value would depend on whether it delivers dependable electricity at a commercially useful cost. The distant target cannot establish future industrial power costs before specific projects and their commercial terms are known.

The legislation revisits a political settlement shaped by the 1987 referendum and closure of the earlier nuclear programme, followed by another referendum in 2011. That history helps explain why the debate extends beyond reactor design to safety, waste and the rights of communities that might host facilities. Site decisions determine where benefits and obligations fall, while waste and oversight rules determine how long-term responsibilities are managed. The delegation addresses those subjects together but leaves much of their practical treatment to decrees and competent authorities. Delays in resolving them could defer investment decisions even if the policy objective remains in place. Clear, enforceable rules would instead help developers compare prospective projects on cost and timing.

For investors in utilities, engineering businesses and the supply chain, the vote creates possible future opportunities rather than confirmed orders. Licensing and financing rules may matter more to the value of an opportunity than the political announcement, because they determine required capital and the timing of revenue. Electricity-intensive businesses face a different question: whether new output will reach the grid at a cost competitive with alternatives when operation begins. Domestic nuclear generation could reduce some exposure to volatile imported-gas prices if it displaces gas-fired power. The size of that benefit depends on the capacity built, its cost and how it runs, none of which the law settles. Parliamentary approval alone therefore cannot establish a near-term fall in energy bills or a specific company's earnings.

The next test is publication of decrees that turn Parliament's delegation into rules on safety, licensing, waste and oversight. Energy Minister Gilberto Pichetto Fratin has said he intends to issue them by the end of 2026, while the law allows 12 months from its entry into force. The texts should show how permits would work and how responsibilities would be divided among the state, regulators and developers. Specific projects with identified sites, financing and construction schedules would then provide a clearer measure of the nuclear programme's pace. Delayed rules or stalled projects would leave any effect on electricity supply distant. Progress on permits and projects would allow the contribution to energy security and cost to be judged against measurable results.
