It is TenneT’s job to guarantee the supply of electricity for its 41 million end-users.

Security of supply

Modern society is powered by electricity. From PCs to traffic lights and from home appliances to mobile phones, we all rely on electricity. It is TenneT’s job to keep the lights on, underpinning the fabric of our society and guaranteeing the supply of electricity to 41 million end-users.

Society is expecting more and more renewable energy to be produced - a development where TenneT sees a crucial role for itself to facilitate this. Gaining acceptance from society for our extensive investment programme, which raises concerns about biodiversity, safety, electromagnetic fields and landscape pollution, is challenging and of high importance to us.

Grid availability

A stable and secure power supply is our reason to exist. In 2016, we achieved 99,99% grid availability, making our grid one of the most reliable in the world. The strong growth of renewable energy is putting pressure on grid stability and making it harder to retain this high level. This is because wind and solar power are volatile as they depend on the weather. TenneT is playing an active role in ongoing discussions in the Netherlands and Germany and also in the European market, about how to deal with the changing landscape and secure a reliable and sustainable energy grid.



It is TenneT’s task to transport electricity safely, efficiently and with minimum impact on the environment.
