TenneT creates, invests and researches for the energy future

12.03.2020

Promoting the energy transition is a priority objective of TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO). This is clearly reflected in the TSO’s just-published Integrated Annual Report. As in recent years, the Annual Report is accompanied by the Green Finance Report 2019.

In line with the energy policy and climate goals of the Netherlands and Germany, TenneT increased its investments yet again in 2019 and spent €3.1bn on the energy transition and supply security (grid availability of 99.9998% in 2019). This financial commitment is even to be stepped up: TenneT is planning annual investments of €4bn to €5bn for the future. The financial performance of the company, with revenues of €4.1bn in 2019 and an EBIT (excluding special effects) of €753m, supports these ambitious plans. Manon van Beek, CEO of TenneT, has every reason to be content with the sound development of the TSO: “We have made great strides again in pursuing our ambition to achieve a sustainable energy future for everyone. Not only in realising and developing new onshore and offshore connections, but also by the required far-reaching international cooperation and working on innovations in close coordination with relevant stakeholders.”

As regards offshore connections, TenneT has already exceeded in 2019 the German government’s expansion target for offshore wind power capacity in the North and Baltic Sea, which is 6.5GW for 2020. With last year’s commissioning of BorWin 3, TenneT’s ninth offshore grid connection system in DC technology, the TSO now has a total of twelve offshore grid connections in operation (nine in DC and three in AC technology) with a total capacity of 7.1GW. But TenneT is not resting on its successes to date: The connection systems DolWin5, DolWin6, and BorWin5 are being developed and will increase the offshore transmission capacity provided by TenneT for wind farms in the German North Sea to almost 10GW by 2025. In addition, Borssele Alpha, TenneT’s first offshore connection system in AC technology in the Dutch North Sea, was installed on schedule and is now ready for operation. Borssele Beta will be completed in 2020.

Onshore, TenneT has eight transmission lines under construction in Germany, more than ever before. In the Netherlands, the 60km-long Randstad 380kV North Ring power line was put into operation, reliably supplying Europe’s most densely populated area with electricity and providing transmission capacity for green energy. At European level, the “green” COBRAcable deserves special mention, which since 2019 directly connects the Dutch and Danish markets for the first time. The German and Norwegian markets will also be directly connected by the NordLink cable, which is currently under construction. On top of this, a proof-of-concept for the North Sea Wind Power Hub has shown the technical feasibility of the concept of multiple wind power distribution hubs in the North Sea.

All these grid expansion projects are complemented by innovative solutions and intensive research to better utilise TenneT’s existing transmission system. These include vehicle-to-grid pilots, the deployment of home storage systems in grid stabilisation and digital solutions for higher grid utilisation. Another long-term innovation project is Element One, a 100MW electrolysis plant to be built in Germany to promote an integrated energy system.

DolWin gamma successfully installed

12.07.2017

The Dolwin3 grid connection for offshore wind farms in the south-western part of the German Bight has the capacity to supply more than one million households in Germany with green energy. The 900MW DC connection – the third in the DolWin cluster – is carried out by TSC member TenneT, the Dutch-German transmission system operator (TSO), and GE, the general contractor of the whole offshore project. With the installation of the DolWin gamma converter platform, another major step towards the successful completion of Dolwin3 has now been taken.

DolWin gamma was shipped on 15 June in Warnemünde harbour in the German federal state of Mecklenburg-Vorpommern. From here it took six days along the German and Danish coast to reach the final destination in the north of Borkum island within a distance of 80 kilometres to the coastal line of Germany. During spells of fine weather the platform was installed onto the so-called jackets, the platform substructure that already had been erected in 2016.

DolWin gamma converts the AC produced by the wind farms into DC, which is transported via submarine and underground cables to the onshore converter station Dörpen West, where the reconversion into AC takes place. Wilfried Breuer, member of TenneT’s executive board and Director Offshore, declares: “The converter platform is one of the largest visible indicators of the German energy transition. Flagship projects such as DolWin3 are essential to provide customers from the north with wind power and to make renewable energy a reality.”
