Russian will begin constructing two new nuclear reactors in Hungary in the coming weeks, Hungary's foreign minister said, reports BBC.
The deal, reached between Russia and the EU state in 2014, aims to expand the existing Paks nuclear plant by nuclear power giant Rosatom.
Russia's nuclear industry has not been subjected to EU sanctions its invasion of Ukraine.
The Paks site currently generates 40 per cent of Hungary's electricity supply.
With the additional two reactors, the nuclear power station - currently made up of four Soviet-built reactors - will see its capacity more than double.
"This is a big step, an important milestone," Szijjarto said in a Facebook post.
"In this manner we will ensure Hungary's energy security in the long term and protect Hungarians from wild swings in energy prices."
Szijjarto added that the nuclear reactors could be ready for service by 2030.
