The project of building the second circuit 110kV transmission line and Cat Ba 110kV substation has a total investment cost of more than VND 110 billion, which includes building the second circuit of Cho Roc - Cat Ba overhead 110kV transmission line with a length of more than 13.6 km; a new Cat Ba 110kV substation in the form of the unmanned substation with a capacity of 50MVA; and 5 new 35kV feeders connecting after Cat Ba 110kV substation. The project is expected to be completed in mid-2022.

The project of building the second circuit 110kV transmission line and Cat Ba 110kV substation is particularly important for the economic, social and tourism development of Cat Ba island in particular and Cat Hai district in general; creating a loop to link with 110kV substations in the area; contributing to satisfying the electricity demand for local socio-economic development, national defense and security in the area.
Currently, Cat Ba Island is supplied with electricity through the only 35 kV power line being built since 1997. During its operation for over 20 years, the power line has been repeatedly rehabilitated by Hai Phong Power One Member Co., Ltd. However, as going through a rugged mountainous area, with difficult conditions for traffic and transportation, the fixing of incidents on the power line usually takes a long time whenever any incidents occur. In addition, the economy and tourism on Cat Ba island have developed strongly in recent years, which has led to an increase in the demand for electricity, making it difficult for the current power grid to meet the hot development needs of Cat Hai district in the coming period.
