Vision, mission and values

We strive to ensure a reliable and uninterrupted supply of electricity in our high-voltage grid for some 41 million people. In doing so, we make every effort to meet our stakeholders' needs by being responsible, engaged and connected.

The world around us is changing rapidly. The European electricity market is becoming more integrated and there is more electricity being transmitted across borders. Pushed by governments and the general public, there is a rapid transition from fossil fuels to renewable energy sources, such as wind and solar power, and increased focus on the need for European energy independence. At the same time, energy generated locally and by individual households is replacing demand for centrally-produced power. Consumers also become producers, or ‘pro-sumers’. Consequently, electricity supply and demand patterns are becoming more complex, making our task to ensure security of supply even more challenging.


Our society has decided on the large-scale introduction of renewable energy, the generation of which has changed the dynamics of supply. At the same time, the dependence on electricity increases further, which demands continuous reliability levels. To cope with these developments, the European electricity market needs to become more integrated. Sound market design, technical and operational innovation, storage solutions and adequate grid capacity are all required to continue to match supply and demand across borders.


Create stakeholder value by providing security of electricity supply in the markets we serve and by pursuing, as a leading TSO, the development of an integrated and sustainable NWE electricity market.
