EU plans to caution against premature nuclear phase-outs to tackle the energy crisis.

The EU is preparing to warn its member states against prematurely closing nuclear plants, according to a draft document obtained by Reuters. This move comes as Europe seeks to strengthen its power supplies in response to the repercussions of the Iran war.

On Wednesday, the European Commission is expected to unveil a set of measures aimed at addressing rising energy costs. The plans, previously highlighted by Reuters, include reductions in electricity taxes and an increase in clean technology investments.

A revised draft viewed by Reuters on Tuesday outlines several initiatives for governments to provide "immediate relief." It advises against the early retirement of energy generation assets, particularly existing nuclear facilities, which can continue to offer stable, affordable, and low-emission electricity. This approach could help reduce reliance on fossil fuels in heating and industrial sectors.

The draft also emphasized that nuclear power plants contribute clean energy, which is important for system integration and enhancing flexibility to support the deployment of additional clean technologies. A spokesperson for the Commission has not yet commented on the draft.

European Commission President Ursula von der Leyen expressed last month that scaling back Europe’s nuclear energy capabilities was a "strategic mistake," highlighting how the Iran war emphasized Europe's vulnerability to rising oil and gas import costs.

Germany, the largest energy consumer in the EU, has phased out nuclear power due to public opposition and safety concerns following the 2011 Fukushima disaster, with its last reactor closing in 2023.

Spain intends to begin shutting down its nuclear reactors in 2027, although energy companies have requested to extend the operation of the first reactor slated for closure. Other EU nations, including Belgium and the Netherlands, have recently reversed their decisions to exit nuclear energy to secure reliable, low-carbon electricity.

The EU's recommendations, while non-binding, also include proposals for distributing energy vouchers to vulnerable populations, financial assistance for installing plug-in batteries and solar panels, lowering public transport fares, and urging businesses to limit air travel where feasible.
