Taiwan: The first onshore substation for Taiwan’s Greater Changhua 2b and 4 offshore wind farms has been successfully energized and is now connected to the national grid, right on schedule. This marks a major milestone for the 920 MW project, developed by Ørsted, located off Taiwan’s southwest coast.
Using a 345 kV high-voltage system, the first of its kind for an onshore substation in Taiwan, the facility sets a new benchmark for offshore wind power transmission, enhancing both efficiency and stability. The substation also introduces several innovative features and sustainability-focused designs.
It includes the world’s largest variable reactor to improve power supply quality, and a dry cooling air conditioning system that saves about 30,000 t of water annually, preventing thermal pollution. Additionally, its prefabricated construction method reduced the build time while improving safety and environmental management.
Local involvement was significant, with more than 80 % of the EPC contract awarded to Taiwanese suppliers, resulting in around 500 direct jobs. Taipower played a critical role in completing the Changgong transformer station, enabling the smooth grid integration.
As installation of the wind turbine foundations and towers continues at full pace, the project remains on track to expand Taiwan’s clean energy capacity and lead the region in offshore wind innovation.
