[3] The power company Fennovoima announced in April 2021 that construction of the plant would begin in 2023 and commercial operation would start in 2029.

[4] In May 2022, in the wake of the Russian invasion of Ukraine, Fennovoima terminated its contract with Rosatom to build the power plant.

On 21 April 2010, the Finnish Government decided to grant a permit (decision-in-principle) to Fennovoima for construction of a nuclear reactor.

[11][12] On 28 July 2016, Rosatom signed a contract with Alstom Power Systems (part of General Electric) for the design and supply of turbine generator equipment package ("conventional island") as well as advisory services for installation and commissioning works.

[17] On 28 February 2014, Voimaosakeyhtiö SF made the final decision to participate in Fennovoima's nuclear power plant construction.

[22] In April 2021, Fennovoima announced that bringing the design and licensing material to the level of Finnish requirements has taken longer than expected.

[4] As the power plant would have generated 10% of Finland's electricity demand and Rosatom would have owned 34% of the plant, this would have meant that Rosatom would have supplied 3% of Finland's electricity production according to Veli-Pekka Tynkkynen [fi], professor of Russian energy politics at the University of Helsinki.

[5] In December 2022, the contract's Dispute Review Board, following International Chamber of Commerce rules, determined that Fennovoima's cancellation was unlawful, though this is subject to appeal (notices of dissatisfaction).
