TSMC’s 30-Year, 1,022 MW Hai Long Offshore Wind CPPA: A Milestone for Taiwan’s Renewable Energy and Industrial Decarbonization
Overview
In 2026, TSMC signed a landmark 30-year Corporate Power Purchase Agreement to become the sole buyer of all electricity from the 1,022 MW Hai Long offshore wind farm, including the newly added 294 MW Hai Long 2A site. This deal secures a stable, long-term supply of renewable energy, helping TSMC meet its accelerated sustainability goals of 60% renewable energy by 2030 and 100% by 2040. For Northland Power and its partners, the agreement provides crucial revenue certainty, improving project financing and bankability. The project supports Taiwan’s ambitious offshore wind targets and sets a strong precedent for corporate clean energy adoption in Asia, despite challenges like technical risks, grid upgrades, and geopolitical tensions.
