Partners
At the TVO Group, we produce climate-friendly electricity with nuclear power. Together with renewable energy sources, it plays a crucial role in mitigating climate change. OL3 brings Finland close to electricity self-sufficiency and marks a major leap toward a carbon-neutral society. With all three nuclear power plant units in operation, 30% of Finland’s electricity is generated on a single island—an island where the entire lifecycle of nuclear power is managed. In ONKALO®, excavated deep into the bedrock, we will be the first in the world to begin the safe final disposal of spent nuclear fuel.
We work with partners who are committed to our safety and quality culture. It is important to us that everyone working at Olkiluoto commits to a high safety culture.
