Corporate Social Responsibility

An important part of our work is to facilitate Europe’s transition to renewable energy. As we do this, we transport more and more wind and solar power to end-users and play our part in building a greener future for society.

Sustainable operations

At the same time, we are transforming the way we work to make our operations more sustainable. Corporate social responsibility (CSR) is one of our leading principles; we care for our people and take responsibility for our impact on the planet, in our operations and supply chain. Take a look at what we do to maximise our contribution to society while minimising our impact as a TSO.


We contribute to society, working to create the best possible environment for our staff and less impact for those affected by our work.
