The Loviisa nuclear power plant consists of two plant units, Loviisa 1 and Loviisa 2. The plant units generate a combined eight terawatt-hours (TWh) of electricity annually for the national grid. That covers of about one-tenth of Finland's electricity production. In terms of availability, Loviisa ranks among the world's best nuclear power plants.
The key figures measuring the Loviisa nuclear power plant's safety and performance reliability have been good throughout its operational history. The annual load factors have risen to and even exceeded 90%. The number of actual serious disturbances has been very low. The electricity produced by the Loviisa nuclear power plant is used as a base load, continuous, year-round, energy source.
Production year 2009 was record-high at Fortum's Loviisa Power Plant. Loviisa unit 1 produced 4.08 TWh and unit 2 produced 4.07 TWh. Total production was record-high in power plant's operation history, 8.15 TWh.
