Urgent need

Con Dao Special Zone, under Ho Chi Minh City, holds significant importance in national defense, security, and sovereignty over islands and seas, and is also a high-value destination in terms of history, culture, and tourism. However, the island's current electricity system mainly relies on diesel with a capacity of over 11MW. Therefore, the need for investment in infrastructure to provide electricity to Con Dao is urgent.

The project to supply power from the national grid to Con Dao has a total investment of over VND 4,923 billion, with Vietnam Electricity (EVN) as the investor, and the Power Project Management Board 3 as the project management representative. The 110kV transmission line bringing electricity from the mainland to Con Dao is over 100km long, with about 80km of submarine cable.

By mid-July, the construction of the overhead line on the Soc Trang coast had basically completed all 32 foundation poles, and steel poles were being installed. The submarine cable section is divided into two parts, with the first section of 41km completed on July 7, 2025, and the second section, 39km long, is currently being worked on by construction units to pull the cables. At Con Dao, all cable connection tunnels and concrete cable trenches along the route have been completed by the contractor. The submarine cable section and the 110/22kV GIS substation are in the process of cable installation and equipment setup. Efforts are being made to complete the installation as soon as possible, in order to move on to the testing and commissioning phase for energizing the entire line.
