Jan de Nul has officially tied up a contract with Synera Renewable Energy (SRE) to install export cables to Taiwan’s Formosa 4 offshore wind farm, powering 500,000 homes. The Jan de Nul Taiwan contract marks a major step in Taiwan’s growing offshore wind sector, helping to strengthen the country’s position as a key player in Asia’s renewable energy transition.
Jan de Nul to install export cables at Formosa 4
Belgian company Jan de Nul has signed a contract with Synera Renewable Energy (SRE) to install export cables at the Formosa 4 offshore wind farm in Taiwan. The project involves the transport, installation, and protection of 60 kilometers of submarine cables, bringing green energy to the coast to power nearly half a million households.
The offshore wind farm is located 20 kilometers off the coast of Miaoli County and will have 35 turbines that will generate 495 megawatts of electricity.
“With this new contract, we continue our journey in Taiwan. These projects will provide Jan de Nul with a continuous project portfolio outlook until 2028.” – Wouter Vermeersch, Director of Subsea Cables Offshore Energy at Jan de Nul
In addition to Formosa 4, Jan de Nul has been selected as the preferred contractor for the export cable to SRE’s Formosa 6 wind farm, located 55 kilometers southwest of Formosa 4. The company is also engaged in cable installation for the Greater Changhua 2B and 4 offshore wind farms and in preparation for Fengmiao 1 in 2026.
Jan de Nul’s role in Taiwan’s offshore wind growth
Active in Taiwan since 1990, Jan de Nul has been supporting the development of offshore wind energy since its inception in 2017. According to Wouter Vermeersch:
“We have successfully delivered several fully operational wind farms through large EPCI contracts, undertaking the entire project from design and procurement to construction and installation. We have played a leading role in supporting Taiwan’s path to net-zero emissions by 2050.”
Taiwan has rapidly increased its offshore wind capacity to more than 3 gigawatts, generated by 374 turbines, placing the country in seventh place globally. With ongoing projects, Taiwan is expected to overtake Belgium this year to reach sixth place. By 2030, the country aims to exceed 13 gigawatts of offshore wind capacity.
