CMS advises Vattenfall on sale of 49% of shares in offshore wind farm projects...
Hamburg – Vattenfall has sold 49% of its shares in the Nordlicht 1 and Nordlicht 2 wind farm projects to BASF. The wind farm zone consists of two separate sites and is located in the German section of the North Sea, around 85 kilometres north of the island of Borkum. The two sites, Nordlicht 1 and Nordlicht 2, have planned capacities of approximately 980 MW and 630 MW, respectively. Full commissioning is scheduled for 2028, when a total of around six terawatt hours (TWh) of electricity is expected to be generated per year, enough to power 1.6 million German households. This makes the Nordlicht wind project the biggest offshore wind farm project that Vattenfall has realised to date. Construction is expected to start in 2026, subject to the final investment decision. Vattenfall is acting as developer and builder of both Nordlicht sites.A CMS team headed by partners Dr Holger Kraft and Dr Jacob Siebert advised Vattenfall on all legal aspects of the transaction.
