The agreement will be finalised by the close of 2025.

According to Siemens Energy, the mini nuclear reactors’ standardised concept allows them to be commissioned at a faster rate when compared with conventional power plants.

The pressurised water reactors of Rolls-Royce SMR can achieve an electrical output of up to 470MW, enough to power 1.1 million homes.

Each Rolls-Royce SMR is expected to generate 1358 megawatt hours (MWh), equal to 45,000 domestic boilers.

A fleet of Rolls-Royce SMRs will contribute £54bn to the UK economy between 2025 and 2105.

Siemens Energy has been a supplier and service provider of components for the “power island” – the non-nuclear part of the power plant – for decades.

The company’s solutions for nuclear power plants feature steam turbines and generators with outputs ranging from 20MW to 1,900MW, as well as operational control technology and control systems.

Siemens Energy executive board member Karim Amin commented: “We are currently experiencing a global renaissance of nuclear energy. Numerous countries are turning to nuclear technology to produce low-emission electricity, and small modular reactors will play a key role in this.

“Siemens Energy brings decades of experience in conventional equipment, while Rolls-Royce has the necessary implementation expertise. This perfect symbiosis enables us to jointly shape the future of energy supply. We are very pleased to be working with Rolls-Royce SMR on this exciting project.”

Situated in 90 countries, Siemens Energy operates throughout the entire energy landscape.
