Ørsted's Greater Changhua 1 & 2a Offshore Wind Farms Mark 2 Years of Commercial Operation, Surpassing 7 Billion kWh in Cumulative Power Generation

Ørsted today (12 May) announced the 2nd anniversary of commercial operations for the 900 MW Greater Changhua 1 & 2a offshore wind farms. Since full grid connection and completion in April 2024, the wind farms have generated more than 7 billion kWh of electricity cumulatively, equivalent to reducing approximately 3.31 million metric tons of carbon dioxide emissions. The projects have also achieved an outstanding safety milestone of more than 850,000 cumulative hours without a lost-time injury (LTI).

Located 35 to 60 kilometers off the coast of Changhua, Greater Changhua 1 & 2a is Taiwan's largest offshore wind farm and the only far-shore wind farm currently in commercial operation. Over the past 2 years, the wind farms have continued stable operations through several typhoons and more than 10 earthquakes above magnitude 5, demonstrating strong resilience. Their capacity factor has also significantly outperformed the global offshore wind average of 42%, underscoring the strong and stable wind resources of the Taiwan Strait.

Christy Wang, Chairperson of Ørsted Taiwan, said: "The stable power generation of the Greater Changhua Offshore Wind Farms is supported by Ørsted's strong local operations and maintenance capabilities, backed by our global O&M network. Around-the-clock operations rely on the close collaboration of nearly 100 local O&M professionals and more than 20 local suppliers. I sincerely thank all colleagues and local partners for their expertise and commitment in ensuring stable generation under Taiwan's complex weather and sea conditions."

Andreas Munk-Janson, Head of Operations APAC at Ørsted, said: "The strong performance of the Greater Changhua Offshore Wind Farms is the result of meticulous daily operations and maintenance, with safety placed at the core of every activity. Through proactive safety management, we have maintained a strong low-incident record across both onshore and offshore operations, while continuously improving generation performance through rigorous procedures and data analysis."

In response to Taiwan's high-temperature, high-humidity environment and complex marine conditions, Ørsted has continued to refine its O&M strategies. These measures include optimizing work-rest schedules, enhancing turbine ventilation and cooling systems, conducting regular emergency response drills, and strengthening safety management protocols. Leveraging more than 35 years of experience operating 30 offshore wind farms worldwide, Ørsted also integrates data analytics and predictive maintenance technologies to identify up to 70% of potential failures in specific components several months in advance, thereby reducing the risk of unplanned downtime and maintaining high asset availability.

Centered around the TSS PIONEER service operation vessel and the Asia-Pacific's largest offshore wind operations and maintenance hub at the Port of Taichung, Ørsted has established in Taiwan an O&M capacity capable of supporting a total of 1.82 GW of offshore wind assets, including the 920 MW Greater Changhua 2b & 4 offshore wind farms. The company will continue delivering stable, large-scale renewable power generation to strengthen Taiwan's energy resilience, energy independence, and sustainable industrial development.

【Ørsted – Offshore Wind Farms in Operation】
．Ørsted is the largest shareholder in Taiwan's first offshore wind farm, Formosa 1 Offshore Wind Farm, holding a 35% stake. Formosa 1 Phase II construction was completed at the end of 2019 and entered commercial operation in early 2020, expanding installed capacity from 8 MW to 128 MW.
．The Greater Changhua 1 & 2a Offshore Wind Farms are located 35 to 60 kilometers off the coast of Changhua County, with a total grid-connected capacity of 900 MW. The projects generate enough clean electricity annually to meet the equivalent yearly power consumption of approximately 1 million Taiwanese households.
．The Greater Changhua 1 has an installed capacity of 605 MW, of which Ørsted holds a 50% ownership stake. The remaining 50% stake is jointly owned by an international infrastructure investment consortium comprising La Caisse (the Québec Deposit and Investment Fund) of Canada and Taiwan's Cathay Private Equity Sustainability Fund.
．At the Greater Changhua 1 Offshore Wind Farms, Ørsted is conducting the world's first coral propagation feasibility study, ReCoral by Ørsted™, which explores the use of offshore wind turbine substructures in tropical waters to create new habitats for coral ecosystems.

【Under Construction – Greater Changhua 2b & 4 Offshore Wind Farms】
．In June 2018, Ørsted secured development rights through a competitive tender for its 2nd large-scale offshore wind project in Taiwan — the 920 MW Greater Changhua 2b & 4 Offshore Wind Farms. In July 2020, Ørsted signed a CPPA with Taiwan's largest semiconductor manufacturer.
．The Greater Changhua 4 Offshore Wind Farm has an installed capacity of 583 MW, with Ørsted holding a 50% ownership stake and the remaining 50% owned by Cathay Life Insurance.
．Ørsted has signed an agreement with Cathay Life Insurance Co., Ltd. and its subsidiary Cathay Power Corporation (collectively "Cathay") for a joint investment under which Cathay will acquire a 55% ownership stake in the 632 MW Greater Changhua 2a Offshore Wind Farm. The transaction is expected to be completed upon the project’s commercial operation date in the third quarter of 2026.
