Siemens Energy has partnered with Rolls-Royce SMR to supply conventional technology for its future Small Modular Reactors (SMRs). In this partnership, Siemens Energy will supply major components such as steam turbines, generators, and auxiliary systems for Rolls-Royce’s planned Generation 3+ modular nuclear power plants. The two companies will finalize the comprehensive agreement for this partnership by December 2025.
Exclusive Technology Supply Agreement
Under the deal, Siemens Energy will exclusively supply Rolls-Royce SMR’s order book reactors with the non-nuclear hardware. Rolls-Royce is designing small nuclear reactors that will use steam turbines and generators to produce up to 470 megawatts of electricity, enough to power 1.1 million homes, marking a significant breakthrough for the energy industry.
SMRs are seen as a future innovation for nuclear power. Smaller, safer, and cheaper than traditional nuclear power plants, they can make a major contribution to the global energy transition. Rolls-Royce SMR designs modular units that speed up construction and bring power online faster than traditional nuclear plants.
Rolls-Royce SMR’s intended pressurized water reactors will be at the heart of the next-generation nuclear power technology. Their modular design will make them deploy more quickly and give operational flexibility, delivering clean and reliable energy.
Karim Amin, Executive Board Member at Siemens Energy, said, “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.”
