Electricity market

The energy sector is developing rapidly. The process of European market integration began some years ago. Its purpose is to create a single European market that enables market parties to trade gas and electricity across national borders easily and efficiently.

TenneT tackles biodiversity at all its 462 high voltage substations

Downloads & Contact

The grid operator TenneT will be helping to promote biodiversity at all its 462 high voltage substations in the Netherlands and Germany. The plan goes into action following spectacular results achieved in a pilot project at three such substations in the Netherlands. The project revealed that nature-friendly maintenance of these sites conserved up to 72 percent of their insect populations. The programme TenneT is now launching will ensure that by 2025, biodiversity-friendly management will be the standard of TenneT's green management.

Ben Voorhorst (Executive Board member): ‘We operate the electricity grid in the Netherlands and large parts of Germany, ensuring 41 million consumers and businesses receive green electricity. Meanwhile, global biodiversity is also under pressure, according to a report by Ipbes (United Nations) this week. With our high voltage connections and stations, in addition to transporting green electricity, we can also contribute to the conservation of nature in another way.’

Conservation of insects and inspect species and flora

TenneT’s assets are located throughout the Netherlands and Germany, offering unique connection points for local biodiversity. This spurred on TenneT to launch a biodiversity pilot project at three high voltage substations in the Netherlands. The measures taken to increase biodiversity are sowing indigenous mixtures to strengthen local biodiversity and meandering mowing. The pilot project showed that meandering mowing leads to the retention of between 58 and 72 percent of insect fauna. These insects would not survive ‘normal’ mowing.

The pilot project was carried out in collaboration with the Vlinderstichting (Dutch Butterfly Conservation). Albert Vliegenthart of Vlinderstichting: ‘TenneT demonstrates that relatively small measures at hundreds of stations can achieve a significant effect. Such conservation of the insect population is impressive, and at the same time crucial given the current challenges facing us on preserving biodiversity.’
TenneT’s contribution to promoting biodiversity is part of its CSR ambition for 2025. It also contributes to TenneT’s objective of playing a leading role in the energy transition as a green grid operator.
