what happened
Newsmetry API, citing Nord Pool, reports that two Belgian nuclear units are currently unavailable. Doel 4, rated at 1,026 MW, has been offline since April 1, 2026, with a restart expected on November 2, 2026. Tihange 3, with 1,030 MW of capacity, stopped operating on April 4, 2026, and is scheduled to return on October 20, 2026.
Belgium has seven nuclear reactors with total capacity of almost 6 gigawatts. Electrabel runs them as part of France’s Engie, which was formerly called GDF Suez. The separate table for reactors due to leave service contains no listed units. A plus sign indicates the latest change.
why it matters
The two outages remove 2,056 MW from Belgium’s available nuclear generation until the stated restart dates. Those timelines matter for assessing prospective electricity availability, while routine maintenance, refueling and unexpected shutdowns can all alter output.
