Amazon has signed a Power Purchase Agreement (PPA) with Skyborn Renewables for 600MW of capacity from the Gennaker offshore wind farm in the German Baltic Sea.

The PPA is the largest ever in the German market, and is tied to the 976.5MW Gennaker offshore wind farm. Power delivery is expected to commence at the end of 2028, upon the wind farms’ commissioning.

According to Skyborn, the PPA will enable it to advance the construction of the wind farm, which is expected to comprise 63 15MW turbines. The project secured a construction permit in late 2025, and construction is expected to commence in the summer of 2026. The project is expected to cost around €3 billion ($3.43bn) to construct.

“By signing our largest power purchase agreement in Germany, we’re giving Skyborn the certainty to move forward with Gennaker, bringing nearly 1GW of new offshore wind capacity onto the grid, strengthening Germany’s energy security, and supporting jobs and investment in the region,” said Rocco Bräuniger, country manager of Amazon Germany, Austria, and Switzerland.

“This agreement with Amazon marks a defining milestone for Gennaker and Skyborn. As our blueprint project, Gennaker demonstrates how large-scale offshore wind can be delivered in a reliable, scalable way. It also reflects the growing need to connect renewable electricity generation with robust and forward-looking infrastructure that enables a resilient energy system. I am extremely proud of our teams to make this happen,” added Adam Thomsen, chief development officer of Skyborn Renewables.

The PPA builds upon a sizable energy offtake portfolio for Amazon in the German market. The company has now contracted more than 1.3GW of power across 12 projects.

Most recently, the hyperscaler signed a 110MW offshore wind PPA with RWE for capacity from the 900MW Nordseecluster B offshore wind farm in the eastern German North Sea. The company also inked another offshore wind PPA with Ørsted for 100MW from Ørsted’s 900MW Borkum Riffgrund 3 Offshore Wind Farm in Germany, back in December 2021.

Amazon Web Services’ main area of operations in the German market is in Frankfurt, where it has operated a cloud region since 2014. In 2024, the company announced that it would spend €8.8bn ($9.44bn) in its AWS Europe (Frankfurt) cloud region by 2026.

The company is also developing data centers outside Frankfurt in Schöneck and Maintal, in the Hesse region of Germany. AWS will invest “more than €1 billion” in the data center in Schöneck alone.

Skyborn Renewables is a global offshore wind energy developer based in Hamburg, Germany. Founded in 2000, the firm is a portfolio company of BlackRock-owned Global Infrastructure Partners. The company has around 750MW of operational capacity, in addition to a pipeline of more than 20GW across Europe, APAC, and the Americas.
