Disagreements between Areva-Siemens, the consortium constructing the reactor, and its client Teollisuuden Voima (TVO) over the plant’s instrumentation and control (I&C) system has been the reason for the delay.
The project has been delayed several times due to surging costs and disputes between Areva-Siemens and TVO.
Reuters quoted TVO’s project head Jouni Silvennoinen as saying: "The delays are because the planning of the plant has taken needlessly long.
"We haven’t examined the supplier’s detailed schedules yet, but our preliminary view is that we could do better (than 2018)."
As per the new timelines, the project construction is slated for completion by the third quarter of 2016 and will commence operations in the last quarter of 2018.
The construction on the 1,600MW plant began in 2005 and was to have commenced operations in 2009.
