The Half Year Report of the Dutch-German TSCNET shareholder TenneT does not only provide satisfactory figures, but also shows that the business of a transmission system operator (TSO) with a control area from the seashores to the Alps is essentially divided into two parts: connecting offshore wind energy capacity to the onshore grid and ensuring the transport of sustainable generated electricity to wherever it is needed. To further support the energy transition, TenneT is accelerating the realisation of large-scale projects in the Dutch sector of the North Sea and on the German mainland. The TSO’s commitment to the European energy future is reflected with a total of €904m of investments in the transmission systems in the first half of 2018 ‒ not only impressive compared to the first half of 2017 (€750m).
By 2030, TenneT plans to have connected a total of 11.5GW of offshore wind energy to the grid in the Netherlands. Three years earlier, in 2027, the TSO aims to achieve a total transmission capacity of 11GW for the German North Sea. The most outstanding onshore infrastructural projects are the German supraregional extra-high voltage lines SuedLink and SuedOstLink with a length of 700km and 580km, respectively, and a combined capacity of 6GW. Both DC lines will partially be realised by means of underground cabling and are joint ventures of TSCNET shareholders. On SuedLink, TenneT cooperates with TransnetBW, and on SuedOstLink with 50Hertz. To help financing its investments in the transmission of the renewables, TenneT in March 2018 again has issued long term green bonds in two tranches with a nominal total value of €1.25bn. Altogether, TenneT has issued €6.25bn in green bonds to date.
Mel Kroon, CEO at TenneT, emphasises the company’s “central position in the energy transition” and considers that the construction of new infrastructure alone is not enough to meet the challenges of the future, “but also the development of innovative hard- and software systems for real-time coordination of the variable supply of green electricity.” Mr Kroon expresses the need for a new energy system, and points out the unexploited potential of green hydrogen for flexibility and storage solutions: “Following the successful development of offshore wind energy, we now need to focus on promoting the production of green hydrogen in order to facilitate long-term energy storage and make the industrial and transport sectors far more sustainable.”
