Purpose, Promise and Principles

Our Principles are the rules we live by at TenneT influencing how we communicate and how we behave, the decisions we make and how we work with others, both in and outside TenneT. They will support us living up to our Purpose and Promise, and are what we want people to recognise us for as we become a more flexible learning organisation.

Everything in energy is connected

Local, national and international. Electricity and gas. Offshore and onshore. Supply and demand.

The people who make energy systems possible, and the people who need them.

And it’s people across governments, businesses, organisations and communities who share the responsibility and the capabilities to drive the energy transition and manage our finite resources as best we can.

In our role as an independent European grid operator, TenneT brings these people and their expertise together with our own, in our pursuit to create a brighter energy future – more sustainable, more reliable and more affordable than ever before.

It’s a challenge that needs new ideas, new technologies and new behaviours that build on the strong foundations we’ve laid. It demands that we do things differently, and that we learn from each other, across industries, because we know we don’t have all the answers ourselves.

It’s why we’re happy to collaborate and share the knowledge and experience that enable us to keep the lights on, so that as a society we can design and deliver the energy system we all need for tomorrow. 

Together, we are lighting the way ahead.
