The transmission system operator TenneT has now awarded the contract for the connection of the Nordergründe offshore wind farm with three-phase alternating current technology. The connection constitutes a part of the projects already planned by TenneT prior to 2011, for which the company has already released a total investment volume of approximately 5.5 billion euros since 2010. Thus TenneT is the largest investor in the energy turnaround and provides a significant contribution to the energy turnaround in Germany by feeding wind energy generated in offshore wind farms into the mainland energy grid and also by expanding the grids on the mainland.
In the future too, TenneT would like to contribute to the successful implementation of the energy turnaround, which, however, requires a fundamental structural change regarding the connection of offshore wind farms. The connection of electricity gained by offshore wind farms in the course of the next years can only be successful if the still to be clarified liability issues are clearly regulated by law, if there is a long-term offshore planning agenda in place, and if the required further investments will rest on multiple shoulders and not be borne by one party only.
The Nordergründe offshore wind farm consists of 18 wind energy plants, which are to generate a total of 111 megawatt of electricity. Thanks to the proximity to the mainland, the wind farm will be connected with three-phase alternating current technology. The cable route will run 28 kilometres from the wind farm to the landing point and from there another four kilometres on land to the Inhausen transformer station, which is being expanded for the feed-in of wind-generated electricity. ABB is the contractor.
