Macron steps back on reactor closures by 2035

France could expand its nuclear fleet by 25GW over the next 30 years instead of shutting down nuclear reactors by 2035, president Emmanuel Macron said today.

Macron asked French utility EdF to assess the possibility of lifetime extension of existing nuclear reactors beyond 50 years. He added that "no nuclear reactor should be shut down in the future, except in the case of safety imperatives".

This turnaround comes despite the French president having pushed for a reduction of nuclear in the power mix during his election campaign in 2017, as a legacy of former president Francois Hollande.

France currently aims to reduce the share of nuclear in its power mix to 50pc, which would be done by shutting down 12 reactors by 2035 as part of its multi-year energy programme. But nuclear safety authority ASN in January recommended reconsidering that target in light of growing concerns over power supply security.

The multi-year energy programme is set to be revised in 2023, subject to parliamentary approval, Macron said.

In addition, a total of six European Pressurised Reactor 2s (EPR2s) would be built by 2050, and plans for eight additional reactors will be studied, Macron said. Construction works are due to start in 2028, and the first plant could come on line in 2035.

The only EPR 2 under construction in France is the 1.65GW Flamanville 3 nuclear unit, the start-up of which was delayed again in January to 2023.

Ambitious renewable goals

While the president was expected to announce the massive investment plan into nuclear energy, he also mentioned a series of measures to boost renewable energy.

Macron intends to raise installed offshore wind capacity to 40GW by 2050, with around 50 wind farms. France currently counts only 17 offshore wind projects under construction or development.

Solar photovoltaic capacity is also due to be raised, to 100GW, from 12.4GW as of the end of 2021. Renewable energy development will benefit from €1bn in support, he added.

The president's message was in line with the recommendations of transmission system operator RTE, which suggested a combination of nuclear and renewables in the country's power mix in 2050.

These announcements come as nuclear operator EdF has been experiencing supply tensions since the end of last year as a result of a tight maintenance schedule on its nuclear fleet, which brought available capacity to a historical low.
