Taiwan-based semiconductor group TSMC signed what’s billed as the world’s largest renewable power deal by agreeing to buy the entire output from a 920MW Orsted offshore wind farm.

The deal will see TSMC offtake full production from the Greater Changhua 2b & 4 project, due to enter service in 2025/26, under a 20-year fixed-price contract, said a statement from the Danish offshore wind giant.
