High-voltage Submarine Cable Agreement to keep ZTT engaged in offshore projects within China's waters
ZTT Submarine Cable & System (ZTTSC) has secured an engineering, procurement, and construction installation (EPCI) contract to supply 94 km of 500 kV, 3-core HVAC submarine cables for Shenzhen Energy’s Honghai Bay VI offshore wind project in Guangdong, China. This pioneering offshore wind development has a capacity of 500 MW, with wind turbines situated more than 30 km offshore.
The project scope specifically involves the design and installation of high-voltage submarine cables that connect the offshore wind turbines, enabling large-scale energy transmission to the onshore grid. Honghai Bay VI represents a significant advancement in China's next-generation offshore energy infrastructure by setting a new technical benchmark with the 500 kV cable voltage level, which enhances transmission efficiency over long distances.
This project, scheduled for delivery in February 2026, will be built in the southern sea area of Honghai Bay Development Zone, Shanwei City, Guangdong Province, within a 62-square-kilometre area. The successful implementation of this 500 MW wind farm will contribute substantially to clean energy generation in Guangdong Province and demonstrate technological progress in offshore wind grid integration in China.
In terms of impact, this project advances China's offshore wind energy capacity and infrastructure capabilities by deploying innovative cable technology and supporting a growing offshore renewable energy sector. This marks another significant win for ZTT in the Chinese offshore wind industry.
It is worth noting that ZTT Group was recently awarded a contract for the supply of submarine cables for the Yangjiang Fanshi II project in China. However, the details of the specific project, such as its location and the exact scope of work, were not disclosed in the article. The article also does not provide any context about the role of offshore wind energy in China's energy mix or the country's renewable energy targets.
Despite the lack of financial details, this project underscores the increasing importance of offshore wind energy in China's energy landscape. The successful completion of the Honghai Bay VI project will undoubtedly contribute to China's efforts to reduce carbon emissions and transition towards a more sustainable energy future.
