Denmark's Orsted said on Wednesday that Taiwan Semiconductor Manufacturing Co has agreed to buy the entire power production from its second offshore wind farm in the Asian country.

Under what Orsted called "the largest-ever contract of its kind within renewable energy", TSMC will for 20 years buy 920 megawatts of power from the Greater Changhua 2b & 4, when the offshore wind farm project is scheduled to be finalised by 2025 or 2026.
