The two projects will raise Vattenfall's Danish portfolio to seven operational wind farms; the utility currently runs five there, generating about 6.5 TWh a year. Both leases carry 30-year terms with a 10-year extension option, and each holds reserved grid connection rights. Hesselø, in the Kattegat between Denmark and Sweden, is sized at around 800 MW, while North Sea I Mid, off the west coast, has a 1 GW minimum. Vattenfall has published no construction timeline or cost estimate, with permitting, environmental assessment and supply-chain contracting still ahead of any final investment decision.
