Tennet's North Sea power transfer jumps 50%

NETHERLANDS/GERMANY: Transmission system operator (TSO) Tennet transferred approximately 7.77TWh of wind energy in the North Sea in the first six months of the year.

The total transmitted in the first half of 2017 exceeded that of the same period last year (5.18TWh) by 50%, Tennet announced.

The 7.77TWh it transferred from its nine offshore grid connection systems off the coast of the Netherlands and Germany corresponds to 72% of the total output (10.83TWh) for 2016.

Between January 2016 and the end of June 2017, the installed capacity of offshore projects in the North Sea increased from 2.95GW to 4.4GW.

Meanwhile, Tennet’s installed connection capacity of 5.2GW in the North Sea has remained constant since February 2016 — the month it added 916MW to the grid.

After the H1 results emerged, Lex Hartman, a member of Tennet’s management board, said: "This expansion, on the one hand, lays clear the present growth in generation output, but a major prerequisite for the successful bringing in of the ‘wind harvest’ was the continual expansion of TenneT transmission capacities.

"Since February 2016 we have already been able to supply more than 5.2GW."

The German government set a target of having more than 6.5GW of offshore capacity by 2020, before ramping up to 15GW by 2030.

As such, Tennet has already connected projects with a capacity totalling more than 80% of the government’s 2020 expansion goal.

The company plans to complete three more grid connection systems by the end of 2019, bringing North Sea transmission capacity up to over 7GW.

TenneT also has plans to create four more connections by 2025, meaning North Sea connection capacity would exceed 10GW.
