Teollisuuden Voima Oyj Company Teollisuuden Voima Oyj (TVO) is a non-listed public company founded in 1969 to produce electricity for its shareholders at cost price. TVO s nuclear power plant produces about one sixth of the electricity consumed in Finland. Electricity is generated at the two Olkiluoto nuclear power plant units Olkiluoto 1 and Olkiluoto 2 (OL1 and OL2) in Eurajoki and at the Meri-Pori coal-fired power plant in Pori. A one-megawatt (MW) wind power plant also produces electricity in Olkiluoto. A new unit, Olkiluoto 3 (OL3), is under construction. In 2011 Olkiluoto 4 project proceeded to the bidding and engineering phase. We support wellbeing of the society by producing electricity to Finnish people through a safe, economical and environmentally benign process. Our vision is to be an acknowledged Finnish nuclear power company. Our operation is based on our vision, ethnical principles and values, and the high level safety culture that we maintain. Our safety culture consists of practices, procedures and attitudes. The promotion of safety culture is one of our most important tasks. The Olkiluoto nuclear power plant produced ca. 14.2 TWh electricity in 2011. This was about one sixth of all electricity used in Finland. TVO s share of the electricity produced at the Meri-Pori coal-fired plant was ca. 0.8 TWh. The production of the wind power plant totaled 0.002 TWh. The electrical output of OL1 and OL2 is 880 MW each. TVO s share of the electricity produced at the Meri-Pori coal-fired power plant is 45%. 4 Pocket Guide 2012
