Taiwan's Star Trade Co. signed a corporate power purchase agreement with developer Synera Renewable Energy Group on September 9, 2026 for the entire 800 megawatts of the Formosa 6 offshore wind project off Changhua County — one of the largest single-buyer corporate PPAs ever signed in Taiwan.
The deal
Formosa 6 sits about 35 kilometres off the coast of Xianxi Township in an 84-square-kilometre lease area awarded in the second round of Taiwan's Phase 3 Zonal Development programme in 2024. The full 800 MW output will now flow to Star Trade, which will retail the electricity to Taiwan's power-hungry semiconductor and manufacturing sectors.
Building on Formosa 4
The two companies previously signed a similar corporate PPA covering the 495 MW Formosa 4 project off Miaoli County. Combined, Star Trade now holds more than 10% of Synera's contracted offshore capacity — an unusually deep single-counterparty relationship in Taiwan's fragmented CPPA market.
Why it matters
Once operational in Q4 2028, Formosa 6 will supply enough clean electricity for roughly 860,000 Taiwanese households. The project's financing plan leans heavily on the CPPA revenue — a structure lenders have increasingly demanded following volatile merchant power prices in Europe and challenging offshore wind economics chronicled in the Waratah Super Battery restart and Econergy's Romania buildout.
What comes next
Synera is scheduled to reach financial close on Formosa 6 in 2027 and begin turbine installation the following year. The company is also advancing engineering work on the co-sited Formosa 7 concession.
