TSMC Signs 30-Year PPA for 294MW from Hai Long Offshore Wind Farm, Securing 1.022GW Total Offtake
Taiwan Semiconductor Manufacturing Company (TSMC), the world’s leading chipmaker, has signed a 30-year Power Purchase Agreement (PPA) with Northland Power to offtake 294 megawatts from the Hai Long offshore wind farm, currently under development off Taiwan’s Changhua coast. The deal expands TSMC’s existing commitment to the project, making it the sole offtaker of the entire 1.022-gigawatt wind farm.
The agreement builds on a previous PPA signed in 2022, under which TSMC agreed to purchase 100 percent of the capacity from the Hai Long 2B and 3 phases, totaling 744 megawatts. That original deal has a 20-year term and will commence once the project reaches full commercial operations. The new PPA covers the entire output of the Hai Long 2A phase, adding 294 megawatts to TSMC’s contracted volume. As a result, TSMC now serves as the exclusive buyer for all electricity generated by the three-phase offshore wind project.
The Hai Long project is a joint venture involving Northland Power (30.6 percent), Mitsui & Co. (40 percent), and Gentari International Renewables (29.4 percent). It comprises three offshore wind sites: Hai Long 2A (294MW), Hai Long 2B (224MW), and Hai Long 3 (504MW). The wind farm is expected to achieve full operations in 2027, a delay from the originally planned 2026 timeline.
“This agreement with TSMC reinforces the strategic importance of Hai Long. Once the switch is complete it will enhance the project’s long-term economic fundamentals and contribute directly to value creation for Northland and its shareholders,” said Christine Healy, president and CEO of Northland Power.
TSMC is one of Taiwan’s largest electricity consumers, accounting for approximately nine to ten percent of the nation’s total power usage. The company has set ambitious sustainability targets, aiming to source 100 percent renewable energy for its global operations by 2040 and achieve net-zero emissions by 2050. To support these goals, TSMC has signed multiple large-scale renewable energy agreements, including a 20-year, 20,000 GWh deal with Ark Power, a 1 GW wind agreement with WPD, and a 920 MW PPA with Ørsted.
The expansion of TSMC’s offtake from Hai Long underscores the growing role of corporate PPAs in driving offshore wind development in the Asia-Pacific region. For Northland Power, securing TSMC as a long-term counterparty improves the project’s financial stability and de-risks its revenue stream, while for TSMC, the deal provides a critical source of clean energy to power its semiconductor fabrication facilities. The agreement also signals that long-term, large-scale renewable procurement remains a central pillar of corporate decarbonization strategies, even as project timelines face typical development delays.
