Big energy users call for probe into extending Belgium’s nuclear plants

Large industrial electricity users in Belgium are urging the government to investigate whether the country’s nuclear power stations can stay open for longer, even without the support of operator Engie.

The call comes from Febeliec, which represents major energy-intensive sectors such as chemicals and steel. The group says a formal study should assess whether all seven of Belgium’s reactors could remain in operation beyond current plans.

At present, only the newest reactors (Doel 4 and Tihange 3) are still running and have already been granted a 10-year extension until 2035. Most of the country’s other reactors have been shut down or are in the process of being dismantled under Belgium’s long-standing nuclear phase-out policy.

Febeliec argues that Engie, which operates the plants, is effectively blocking further research due to its dominant position. “This is not about Engie, but about the future of the nuclear stations,” said energy expert Andreas Tirez. He added that if the company refuses to cooperate, the government should allow other parties to carry out the study.

The organisation believes that keeping more nuclear plants open could improve energy security and reduce reliance on gas imports, an issue that has become more pressing due to recent geopolitical tensions. It also estimates that electricity prices could fall significantly, potentially saving up to €2 billion per year.

However, Engie has dismissed the idea as unrealistic. A spokesperson told VRT NWS that restarting closed reactors would be costly, take years, and may not be technically or safely feasible. Some facilities have already begun dismantling, while others face structural or regulatory challenges.

Febeliec maintains that government intervention may be necessary if Engie refuses to act. It points to past cases where operators were required to keep power plants running in exchange for compensation.

For now, it remains unclear whether Belgium’s government will back the proposal.
