Typhoon Danas, the first typhoon to hit Taiwan directly in 2025, swept north along Taiwan's western corridor, presenting a true test for offshore wind farms in the Taiwan Strait. Despite the severe conditions, all 421 offshore wind turbines in the strait continued generating electricity. Some wind farms exceeded 90% of their capacity, and as of July 7, the instantaneous peak in wind farm generation reached 2.29 GW, accounting for 9.2% of total electricity consumption.

According to the Energy Administration of the Ministry of Economic Affairs (MOEA), data from the Central Weather Administration showed sustained wind speeds reached nearing 40 m/s, with even stronger gusts recorded that night. The weather tower at Waisanding Sandbar recorded gusts reaching Beaufort scale 17. Despite harsh conditions, offshore wind turbines in the Taiwan Strait continued to operate safely.

In 2017, the MOEA announced typhoon-resistance standards for Taiwan's offshore wind turbines. All turbines in Taiwan comply with the Class T standard, capable of withstanding maximum wind speeds of 57 m/s (Beaufort scale 17). Currently, when wind speeds exceed 25 m/s (equivalent to Beaufort scale 10), offshore wind turbines in Taiwan automatically activate protective mechanisms, halt operations, and adjust blade pitch angles to reduce wind resistance and prevent damage.

During the typhoon, the Energy Administration of the MOEA activated its offshore wind typhoon preparedness and safety reporting mechanism to monitor operational conditions across all wind farms. Moreover, due to the strong peripheral winds of Typhoon Danas, some wind farms reached over 90% generation capacity, providing Taiwan abundant green electricity during the period.

The Energy Administration of the MOEA emphasized that, despite the severity of Typhoon Danas, Taiwan's offshore wind turbines remained safe and successfully converted the strong winds into power. This demonstrated the impressive performance of Taiwan's renewable energy even during extreme weather conditions. The Energy Administration will continue to ensure that offshore wind developers complete all wind farm construction and the grid connection on schedule. This not only helps reduce air pollution and eliminate carbon emissions, but also achieve Taiwan's energy transition goals.
