9.51TWh – this is the considerable total amount of offshore wind power that TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), transmitted from sea to land in the first half of 2019. This means that the first half of 2018 (8.17TWh) will be exceeded by a whopping 16%, while on the German market offshore wind energy accounts for a strong 15% of total wind energy generation. At the same time, the cost efficiency of new offshore grid connection systems has further improved in recent months through the standardisation of TenneT’s offshore grid connection systems and the combined expertise of TenneT as a leading TSO at sea.
With the connections currently planned and under construction, TenneT will increase offshore transmission capacity in the German North Sea to almost 9GW by 2024. However, current efforts in Europe will not be sufficient to achieve the climate targets of the Paris Agreement. TenneT therefore calls for a stronger expansion of offshore wind energy in Europe to create a low carbon energy future. TenneT COO Tim Meyerjürgens refers to international studies and scenarios that indicate that “an accelerated and large-scale roll-out is necessary”.
In this context, Meyerjürgens also points to the North Sea Wind Power Hub (NSWPH) concept, for which a positive feasibility study has just been carried out. The North Sea has great potential for offshore wind power, and the NSWPH consortium’s approach could result in 180GW of offshore wind power by 2045. Meyerjürgens explains: “A future internationally coordinated approach could implement the connection and integration of a roll-out of large-scale offshore wind energy more effectively and at considerably lower costs of up to 30% than with continued individual national planning.”
