Under the terms of the N-9.4 offshore wind concession awarded by the Federal Network Agency, North Sea OFW One GmbH will pay an annual contribution of €8.1 million for 20 years to the electricity transmission system operator responsible for connecting the project, starting once the wind farm is commissioned.
On 16 June 2025, the Federal Network Agency (Bundesnetzagentur) awarded the N-9.4 offshore wind concession in the German North Sea to TotalEnergies via its shareholding in North Sea OFW One GmbH, following a dynamic auction triggered by multiple zero-subsidy bids. The award grants rights to develop 1 GW of offshore wind on an area of around 141 square kilometres about 150 kilometres northwest of Heligoland for 25 years, extendable to 35 years; TotalEnergies bid €180,000 per megawatt (about €180 million total) and committed to pay €18 million to the federal government in 2026 for marine conservation and €8.1 million annually for 20 years to the transmission system operator from commissioning, while planning to develop N-9.4 in a cluster with its adjacent N-9.1 and N-9.2 sites.

North Sea OFW One GmbH, N-9.4
On 16 June 2025, TotalEnergies, via its subsidiary North Sea OFW One GmbH, won the German Bundesnetzagentur auction for the 1GW N-9.4 offshore wind site in the North Sea in a dynamic bidding process. The final bid of €180,000 per megawatt obliges the developer to pay a one-off concession fee of €180 million for the 1000MW area, which has not been centrally pre-investigated and will be connected via a 1GW grid link.
In February 2025, Germany’s Federal Network Agency launched the competitive tender for the N-9.4 offshore wind site in the German North Sea, a roughly 141-square-kilometre area able to host around 1 GW of capacity. The auction, run under section 20 of the WindSeeG for a non-centrally pre-investigated area, initiated the multi-stage bidding process that would later be won by TotalEnergies’ subsidiary North Sea OFW One GmbH.
