50Hertz's Ostwind 2 project has reached a new milestone with the installation of around 170 kilometres of cable, both onshore and offshore, over recent months. Now, the last section of the submarine cable is being laid on schedule to complete the second of the total of three 220 kV cable systems.

Ostwind 2 is a grid connection project, which will connect two future offshore wind farms in the Baltic Sea,
Arcadis Ost 1 and Baltic Eagle, to the German high voltage grid. The project includes the installation of three submarine cable systems to deliver this power. They will connect to the German transmission network at the substation Lubmin (Mecklenburg-Vorpommern).

Three cable systems will be laid in the Ostwind 2 project: Two cables lead to the
Baltic Eagle wind farm, and one cable to the Arcadis Ost 1  wind farm. The installation of the third cable system, which is already in production, will begin in 2022.

"Five years ago we announced that we would complete the two cable systems in 2021. Back then, we moved forward ambitiously - and today we can say: we show results! Our Ostwind 2 project is right on schedule. Taking into account that we had to do pioneering work in many places to develop the Baltic Sea as a German offshore wind location, this target was certainly ambitious in 2016. The fact that we are now reaching this crucial milestone as planned not only shows to our project partners that you can rely on 50Hertz,"
said Stefan Kapferer, CEO of 50Hertz.

The Belgian offshore wind farm developer Parkwind will operate the
Arcadis Ost 1 wind farm. Parkwind and 50Hertz will operate a joint offshore platform for the wind farm. The installation in the Baltic Sea takes place next summer. The two companies agreed on this in a memorandum of understanding in 2019.

Arcadis Ost 1 wind farm will have a capacity of about 257 MW and is located in the Baltic Sea, 19 km north-east of the island of Rügen, within the 12 nautical mile zone of the Federal State Mecklenburg-Western Pomerania, Germany. Parkwind secured grid capacity for the project in the offshore wind auction in Germany back in 2018. Offshore installation works are expected to start works in 2022. It is expected to be operational in 2023, and will be capable of generating enough green electricity for the annual power consumption of more than 290,000 homes.

Iberdrola's 476 MW
Baltic Eagle project is being developed off the island of Rügen, in the German waters of the Baltic Sea. The project, which will span a 40 km2 area, is expected to be completed in 2024 and will consist of 50 Vestas V174-9.5MW wind turbines. It is Iberdrola's second array to be built in the Baltic Sea; the first was Wikinger.
