The Most Powerful Steam Turbine in the World Will Be Installed at the Hinkley Point C Nuclear Power Plant in England and Will Produce 3.2 GW of Energy Over the Next Sixty Years
The most powerful steam turbine in the world will leave the giant General Electric factories in Belfort to equip the Hinkley Point C nuclear power plant, under construction in the southwest of England. The largest rotor in the world, associated with this turbine, has just been successfully tested, GE said in a statement.

Measuring 1.9 meters, the equipment named Arabelle will be the most powerful nuclear steam turbine in operation. “Inserted into a compensation pit specially designed for large turbines, the 8-meter-wide module rotated at a speed of 1,500 revolutions per minute,” General Electric reported.
The purpose of a turbine, accompanied by an alternator, is to convert steam into electricity. Longer blades on the turbine rotor increase the electrical output of the nuclear power plant, optimizing the “condenser vacuum,” reducing “bleed losses,” and increasing the “turbine efficiency,” says GE.

50% of the Global Turbine Fleet
The most powerful steam turbine in the world will be installed at the Hinkley Point C nuclear power plant in England, built by EDF Energy, a wholly-owned subsidiary of EDF in the UK. It will allow the production of 3.2 GW of energy over the next sixty years. The installation will be equipped with two EPR-type reactors.
The tested rotor is expected to be delivered to the factory in 2021. “This critical component of the turbine is an important milestone in the first quarter of 2021 for the Hinkley Point C project, achieved on schedule, despite the pandemic,” says Guillaume Callewaert, manager of the HPC program at EDF, quoted in the General Electric press release. In this contract, General Electric supplies and orders the two conventional islands of the two future EPRs (turbine and alternator) and also provides engineering services. “At GE Steam Power, we are proud of our involvement in such an important project,” says Frédéric Wiscart, Project Director at GE Steam Power.
Earlier this year, EDF announced a delay in the construction of this plant due to the COVID-19 pandemic, which delayed the construction site from 2020, launched in 2015. The start of the first unit is scheduled for June 2026, six months later than planned. According to Le Monde, this project amounts to between 25 and 26 billion euros.
The Most Powerful Steam Turbine in the World Built by General Electric
The Arabelle turbine to be installed at Hinkley Point C will be the most powerful steam turbine in the world. General Electric, which acquired this know-how from Alstom in 2015, is expected to contribute 20 GW of power in the coming years with this Arabelle steam turbine technology, “bringing the Arabelle fleet to 53 GW globally,” concludes the press release. General Electric is responsible for 30% of the global steam turbine production, while 50% of the operating global steam turbine fleet is GE technology.
