On top of the 900MW secured in the first procurement round, awarded in April, Ørsted has won an additional 920MW of capacity across two projects in its Greater Changhua zone.
The two sites will be 337.1MW and 582.9MW in size, and were both awarded at a bid price of TWD 2,548/MWh ($81/MWh).
Canada-based Northland and its local partner Yushan Energy, meanwhile, announced its Hai Long 2 and 3 sites, 232MW and 512MW respectively, were also successful.
Northland secured the capacity with bid prices of TWD 2,225/MWh ($73/MWh) for Hai Long 2 and TWD 2,503/MWh ($82.49/MWh) for Hai Long 3.
The Hai Long 2 site was awarded 300M of capacity in April's feed-in tariff procurement round.
All four sites are required to be online by 2025.
"The outcome of the auction proves once again that when governments commit to ambitious buildout targets and create stable, transparent and good framework conditions, the offshore wind industry will deliver," said Ørsted wind power CEO Martin Neubert.
John Brace, CEO of Northland, added: "This additional capacity will enhance our ability to generate efficiencies in the delivery of world-class offshore wind projects that will build up the local supply chain, supporting the achievement of Taiwan's ambitious green energy targets from multiple aspects."
The Taiwanese government has set the target of having 5.5GW offshore wind capacity installed by 2025.
