TenneT Taps Into CLENS Wind Database

German energy service provider Clean Energy Sourcing (CLENS) has won a contract to provide TenneT with data on current and forecasted generation on wind farms to help optimise the transmission system operator’s net and curtailment management.

TenneT often has to carry out network stabilizing interventions on windy days in order to prevent overloading of individual network elements.

The so-called curtailment measures reduce the feed-in capacity of wind farms for a certain period to avoid overloads in the transmission network. The downside of curtailment is that it stops the electricity generation at wind farms and generates costs due to compensation payments.

CLENS has agreed to provide TenneT with real-time data from wind farms with an installed capacity of more than 800MW to make network interventions such as curtailment more efficient.

“With the increasing share of renewable energies in power generation, data on the generation of renewable energies is becoming increasingly important. Thanks to the digital data usage, we are able to fine-tune the feed-in of the wind power plants more closely to the grid capacities and thus achieve a safe and economic operation of the electricity grid that correspond to a growing share of fluctuating green electricity,” said TenneT CEO Urban Keussen.

“We see the close cooperation between TenneT and CLENS as an important milestone in the digitalization of the energy system.”
