All inter-array cables at Ørsted's new offshore wind farm in Taiwan installed and energized
What happened
Ørsted has installed and energised all inter‑array cables at the Greater Changhua 2b and 4 offshore wind farms, and commissioning and grid integration work is continuing ahead of full operation. The commissioning phase now drives acceptance tests, warranty starts and O&M readiness for the project’s offshore systems. Watch whether final grid handover and CPPA milestones trigger immediate spare‑parts demands and final supplier payments
Buyer takeaway
Treat energisation as a contractual handover event that likely triggers acceptance tests, warranty start dates and final payments — confirm those gates now
Cost / money
The cost profile shifts toward O&M and spare parts as the project enters operations; retention releases and parts demand will affect near‑term cashflow
Supplier / commercial
Suppliers can use acceptance and warranty triggers to press for final invoices or to limit liability; include witnessed testing and hold‑points
Safety / operations
Energised cables raise HV testing and marine exclusion requirements; ensure competent testing providers and third‑party witnessing are scheduled
What to watch
Watch for delays in grid handover or CPPA activation that can postpone warranty windows or shift liability; monitor supplier readiness for immediate O&M handover
Key facts

Once fully operational, which is expected in the third quarter of 2026, Greater Changhua 2b and 4 will supply renewable electricity to Taiwan Semiconductor Manufacturing Company Limited (TSMC) under a corporate power purchase agreement (CPPA) signed in 2020
The 66th and final wind turbine was installed in January this year
