17 Jan (NucNet): The lack of alternative low-carbon energy sources that are as reliable as nuclear means France’s “ambitious” plans to reduce its share of nuclear from 78% in 2015 to 50% by 2025 might not be achievable, the International Energy Agency (IEA) said today.
The Paris-based agency said France – which has the world’s highest share of nuclear in its electricity mix – must assess possible changes in energy demand and supply and to guarantee “continuous security of electricity supply” as it pushes ahead with its plans for an “energy transition” up to 2050.
“The implementation of the 50% target remains challenging given the large role that nuclear electricity plays in the French mix and the average age of the fleet, the IEA said.
As the cornerstone of the transition, the role of renewable energy in the power mix is to be increased to 40% by 2030, from its current share of 16.5%, and France aims to accelerate energy savings and reduce the share of nuclear in the mix.
However, according to the IEA the success of the transition will depend on the mobilisation of “significant investment” for the increase of renewable energy and energy efficiency, and the closure or long-term operation of the nuclear fleet.
The long-term visibility of financing remains “a challenge”, the IEA said.
