2.1 Procedure

Title : Market consultation for the maintenance and repair of TenneT’s offshore assets in the North Sea
Description : TenneT is a leading European transmission system operator. We are committed to a secure and reliable electricity supply – 24 hours a day, 365 days a year. We are helping to shape the energy transition – for a sustainable, reliable, and affordable energy future. TenneT Germany is the largest transmission grid operator in Germany (based on grid length as of 31 December 2024). The company operates critical infrastructure that secures access to a reliable, sustainable and affordable electricity supply. TenneT Germany is one of the largest investors in electricity grids on land and at sea in Germany. Located at the Northwest European energy crossroads, TenneT Germany connects: North and South. Offshore and Onshore. Germany and Europe. With its over 5.000 employees (internal and external) the company builds, maintains and operates Germany's largest transmission grid with a length over 14.000 km connecting more than a third of the European Union’s total offshore wind capacity. Its growth is driven by a rapidly evolving electricity demand that requires a flexible and growing grid architecture. TenneT Germany is part of TenneT Group, the European leader in cross-border grid development and pioneer in linking mainland Europe to one of the world’s largest renewable energy sources, the North Sea. The aim of this market consultation is to identify the most advanced maintenance concept available on the market for the maintenance of a number of offshore installations (AC & DC) in the German North Sea. What is the common service set-up? What are the current innovations that shape the market and how do you drive this development? What is the usual amount of standardization and what is your specific competitive edge that makes you a role model for the whole market? Furthermore please challenge TenneT´s described plans and the set-up in order to facilitate a subsequent partnership with the aim of mutual success by describing the ideal strategy from your perspective. If feasible, a thorough description in the open text fields is highly appreciated in order to give TenneT the opportunity to learn about the market capabilities. With this in mind, we would like to ask you for feedback on the tender. If possible, a detailed description in the open text fields is very welcome. TenneT reserves the right to invite selected participants of this market exploration to further detailed discussions after evaluation of the results. These are expected to take place in September, 2025. You can find the questionnaire and the associated soil surveys in the “Questionnaire” module. Thank you in advance for your participation!
