Alstom Power wins turbine generator order for Finnish nuclear plant

Hanhikivi NPP

Alstom Power Systems, part of GE, will deliver a turbine generator set for Fennovoima’s Hanhikivi 1 nuclear power plant in Finland.

The contract covers the design and supply of the turbine generator equipment package as well as advisory services for installation and commissioning works.

The set will be based on Alstom Arabelle technology and the design work will start immediately. The delivery and installation schedule will allow the commissioning of the power plant to begin in 2023 and commercial operation in 2024.

The turbine generator contract is one of the biggest equipment supply contracts for the Hanhikivi 1 unit, and the contract is a significant milestone for the project.

The turbine generator is used to convert the steam generated in the reactor island into electricity to be distributed to the national grid.

In practice, almost dry steam from the reactor unit is piped to the turbines. This heat energy makes the turbines rotate and the generator – which is on the same shaft as the turbines – converts the kinetic energy of the turbines into electricity.
