The world leading offshore TSO

Wilfried Breuer, Member of the Executive Board, TenneT B.V.

TenneT – two TSOs, one company

Europe‘s first transnational TSO Connections to 10 TSOs – in the center of the European electricity market 20.997 km of ehv- and hv-lines 2.2 bn. € turn over in 2013 2.600 employees secure the power supply for 36 m. people Legal obligation to expand, operate and maintain the power grid on- and offshore

Legal framework

§ 17 d EnWG „The TSO, in whose control area an OWF has to be connected to the

• nshore grid, is obliged to build and operate the grid connection according

to the offshore grid development plan.“ Legal obligation to connect OWF

Current Situation – OWF in Germany

German renewable energy targets for offshore wind: 6.500 MW by 2020. As of today TenneT has awarded grid connection capacity of more than 7,1 GW. Among these are 9 DC-systems and 3 AC-systems. The draft Offshore Grid Development Plan (O-NEP) foresees 3 additional projects (2.700 MW) to be tendered until 2024. Only 3 OWF are in operation, 7 under construction and 3 officially approved and with final investment decision. TenneT is legally obliged to up-front services.

TenneT‘s vision for Wind op Zee

TenneT has experience in connecting OWF since 2007. As of today TenneT has awarded grid connection capacity of more than 7,1

• GW. The draft Offshore Grid Development Plan (O-NEP) foresees 3

additional projects to be tendered until 2024. TenneT has relevant competencies to connect OWF:

̵ Abilities to handle large offshore projects for more than 5 years ̵ Skills and proficiencies in large scale project organization ̵ Expertise and experience in planning, consenting, permitting and

• perating & maintaining grid connections

Based on TenneT‘s experience with connecting OWFs in Germany, TenneT suggests to be the designated Offshore TSO in the Netherlands as well. TenneT is the most experienced offshore network developer

TenneT is Europe´s first cross-border grid

• perator for electricity. With approximately

20.000 kilometres of (Extra) High Voltage lines and 36 million end users in the Netherlands and Germany we rank among the top five grid operators in Europe. Our focus is to develop a north-west European energy market and to integrate renewable energy. Taking power further www.tennet.eu
