This text is based on corporation information of TVO:
Teollisuuden Voima Oyj (TVO) is a public company established in 1969 producing electricity for its shareholders at cost price. TVO's nuclear power plant produces about one sixth of the electricity used in Finland. Electricity is generated at the two Olkiluoto nuclear power plant units Olkiluoto 1 and Olkiluoto 2 (OL1 and OL2) at Eurajoki and at the Meri-Pori coal-fired power plant in Pori. A new unit, Olkiluoto 3 (OL3), is under construction at Olkiluoto. TVO has filed an application for a decision-in-principle to construct a fourth nuclear power plant unit at Olkiluoto in spring 2008.
The main mission of TVO is to produce electricity for shareholders safely and economically without carbon dioxide emissions. TVO's vision is to be a world-class nuclear power company that is appreciated by Finnish society. Values of the company are responsibility, transparency, pro activity and continuous improvement.
The Olkiluoto nuclear power plant produced ca. 14.5 TWh electricity in 2009. It was about one sixth of all electricity used in Finland.
TVO's generating capacity consists of the Olkiluoto nuclear power plant units Olkiluoto 1 and Olkiluoto 2 with an electrical output of 860 MW each and the 257 MW share in the Meri-Pori coal-fired power plant.
