Finland’s much-delayed Olkiluoto 3 (OL3) nuclear reactor, Europe’s largest, will begin regular output on Sunday, its operator said on Saturday, boosting energy security in a region to which Russia has cut gas and power supplies.
Nuclear power remains controversial in Europe, primarily due to safety concerns, and news of OL3’s start-up comes as Germany on Saturday switches off its last three remaining reactors, while Sweden, France, Britain, and others plan new developments.
OL3’s operator Teollisuuden Voima (TVO), which is owned by Finnish utility Fortum and a consortium of energy and industrial companies, has said the unit is expected to meet around 14% of Finland’s electricity demand, reducing the need for imports from Sweden and Norway.
Construction of the 1.6 gigawatt (GW) reactor, Finland’s first new nuclear plant in more than four decades and Europe’s first in 16 years began in 2005. The plant was originally due to open four years later but was plagued by technical issues.
OL3 first supplied test production to Finland’s national power grid in March last year and was expected at the time to begin regular output four months later, but instead suffered a string of breakdowns and outages that took months to fix.
As a result of the startup, analysts have said Finland, the only Nordic country with a large power deficit, can expect lower electricity costs.
Russia’s power exports to Finland ended last May when Russian utility Inter RAO said it had not been paid for the energy it sold, a consequence of the widening gulf between Moscow and Europe over the war in Ukraine.
Russian state export monopoly Gazprom shortly after ended shipments of natural gas to the Nordic nation.
