The Belgian government announced plans on Wednesday to purchase the country’s seven nuclear reactors from French utility Engie, a full takeover that reverses a 23-year-old policy to exit atomic power. Prime Minister Bart De Wever said the deal aims to secure energy supplies and reduce dependence on fossil fuel imports. The two sides are targeting a final agreement by October 1.
The proposed acquisition would immediately halt the dismantling of five reactors shut between 2022 and 2025. Only two units, at the Doel and Tihange plants, remain operational. Their operating licenses were recently extended to 2035.
Nobody expected this pace. The 2003 law mandated a complete nuclear exit by 2025. It prohibited new construction and capped reactor lifespans at 40 years.
That legislation now faces formal suspension. De Wever framed the decision as a matter of sovereignty. “This government is choosing safe, affordable and sustainable energy, with less dependence on fossil fuel imports and more control over our own supply,” he posted on X. The statement signals a profound shift in Belgian energy strategy.
A joint communiqué from the government and Engie went further. It outlined ambitions to not only extend existing operations but to develop “new nuclear capacity” in Belgium. The language was deliberate.
It marks the first official endorsement of building new reactors since the phase-out began. Engie confirmed the negotiations in a brief statement. The company, which is majority-owned by the French state, has long sought to limit its exposure to Belgium’s aging nuclear infrastructure.
Safety concerns and repeated shutdowns have made the reactors a political and financial liability. The Doel and Tihange plants have a troubled history. Reactors were taken offline repeatedly for inspections after cracks and water leaks were discovered in pressure vessels.
In 2015, plans to operate units beyond their 40-year design life triggered formal complaints from neighboring Germany, the Netherlands, and Luxembourg. Fear spread across borders. The German city of Aachen, located roughly 70 kilometers from Tihange, began distributing iodine tablets to residents in 2017.
The move was a stark public health precaution against potential radiation leaks. It underscored the deep regional anxiety surrounding the Belgian fleet. That anxiety never fully dissipated.
But the energy crisis triggered by Russia’s invasion of Ukraine in 2022 rewired political calculations across Europe. Belgium’s decision mirrors a broader continental reassessment of nuclear power. The economic toll of volatility changed minds.
Gas prices spiked. Supply chains fractured. Governments from France to Sweden and the Netherlands extended reactor lifetimes or announced new construction programs.
Belgium’s U-turn is the latest, and one of the most dramatic. Behind the diplomatic language lies a complex financial negotiation. The government must agree on a purchase price for aging assets, assume long-term decommissioning liabilities, and manage radioactive waste storage.
These costs are substantial. Engie has previously estimated its Belgian nuclear provisions at over €10 billion. Thierry Saegeman, Engie’s Belgium CEO, acknowledged the complexity in a brief statement.
He said the company would work “constructively” toward the October deadline. The tight timeline leaves little room for error. Energy Minister Tinne Van der Straeten, a Green party member, now faces the task of reconciling her party’s anti-nuclear roots with the government’s new direction.
She has previously advocated for a gas-fired capacity mechanism as a bridge technology. That position appears overtaken by events. Industry groups reacted positively.
The Federation of Belgian Enterprises welcomed the “pragmatic turn” toward reliable baseload power. Manufacturing sectors, particularly chemicals and steel, have warned for years that intermittent renewables alone cannot sustain their operations. Environmental organizations were less enthusiastic.
Greenpeace Belgium called the decision “a costly distraction from real climate solutions.” The group argued that investing in new nuclear would divert billions from wind and solar deployment. The debate is not new. It is now settled.
The timeline concerns many observers. Reaching a binding agreement by October 1 requires resolving valuation disputes, regulatory approvals, and parliamentary scrutiny. The government has not yet disclosed how it will finance the acquisition.
Parliament must also vote to suspend the 2003 phase-out law. The coalition government, led by De Wever’s Flemish nationalist N-VA, holds a fragile majority. Opposition parties have already signaled resistance.
The socialist Vooruit party demanded guarantees on consumer electricity prices before supporting any deal. History hangs over the negotiations. Belgium’s nuclear saga began in the 1970s with the construction of seven reactors across two sites.
Doel, near Antwerp, houses four units. Tihange, near Liège, has three. They once supplied over half the country’s electricity.
By the early 2000s, safety incidents and political pressure led to the phase-out law. The discovery of thousands of cracks in Doel 3 and Tihange 2 reactor vessels in 2012 intensified public fear. Regulators ordered extended shutdowns.
Trust eroded. That trust is now being rebuilt on different terms. The government’s statement explicitly linked nuclear power to “climate objectives, industrial resilience and socio-economic prosperity.” The framing is new.
It treats atomic energy not as a necessary evil but as a strategic asset. Key takeaways from this development are clear. - Belgium is reversing its 2003 nuclear exit law and will acquire all seven reactors from Engie. - The deal halts decommissioning of five shut reactors and paves the way for new nuclear construction. - A final agreement is targeted by October 1, with complex financial and regulatory hurdles ahead. - The decision aligns Belgium with a broader European trend of extending nuclear power amid energy security concerns. Why it matters extends beyond Belgium’s borders.
The decision validates nuclear power as a cornerstone of Europe’s decarbonization and energy independence strategy. For Belgian households and industries, it promises stable baseload electricity but raises questions about who bears the long-term financial risk. The European Commission has increasingly accepted nuclear as part of the green taxonomy.
Belgium’s move provides political cover for other hesitant nations. It also pressures Germany, which closed its last reactors in 2023, to reconsider its position as industrial competitiveness concerns mount. What comes next is a sprint.
Negotiating teams will meet weekly through the summer. A draft agreement must emerge by September for parliamentary review. The government must also submit a financing plan to the budget committee.
Watch for the valuation report. Independent auditors will assess the reactors’ worth and the decommissioning fund’s adequacy. That number will determine whether the deal is a strategic masterstroke or a fiscal burden.
The October 1 deadline is firm. The consequences are permanent.
