All Inter-Array Cables at Ørsted’s New Offshore Wind Farm in Taiwan Installed and Energized

Why It Matters

The project supplies clean electricity to a key semiconductor manufacturer, reinforcing Taiwan’s energy security and accelerating offshore wind adoption in Asia. Ørsted’s delivery demonstrates the viability of ultra‑large turbines, setting a benchmark for future projects.

Key Takeaways

• 66 14‑MW turbines installed, first globally with 115‑m blades
• All inter‑array cables energized; 42 turbines now grid‑connected
• Project will deliver 920 MW, powering TSMC under 2020 PPA
• Full commissioning expected Q3 2026, boosting Taiwan’s offshore capacity
• Construction began Feb 2025; first power generated July 2025

Pulse Analysis

Ørsted’s Greater Changhua 2b and 4 offshore wind farms represent a watershed moment for the Asian offshore market. By deploying 66 Siemens Gamesa SG 14‑236 turbines—the world’s first 14 MW units with 115‑metre blades—the project pushes the envelope on turbine size, efficiency, and logistics. Larger rotors capture more wind at lower speeds, reducing the number of foundations needed and cutting overall capital expenditure, a trend that other developers are now emulating across the region.

The timely energisation of all inter‑array cables and the grid connection of the second‑phase turbines underscore Ørsted’s sophisticated commissioning strategy. Subsea cable installation and offshore substation integration are among the most complex phases of offshore wind construction, often causing schedule slippage. Ørsted’s ability to synchronise these systems ahead of the projected Q3 2026 full‑operation date signals strong project management and risk mitigation capabilities, reinforcing its reputation as a global offshore leader.

Beyond technical achievements, the farm’s power purchase agreement with Taiwan Semiconductor Manufacturing Company (TSMC) highlights the strategic role of renewable energy in high‑tech supply chains. As TSMC expands capacity to meet global chip demand, securing stable, carbon‑free electricity becomes a competitive advantage. The 920 MW output will offset a substantial portion of TSMC’s energy consumption, supporting Taiwan’s goal of achieving 20 % offshore wind generation by 2030 and signaling to investors that large‑scale renewable projects can reliably serve energy‑intensive industries.
