Doc Soi - Dung Quat 500KV Substation starts operation

A 500KV Substation installed at Doc Soi in Binh Son district, Quang Ngai which is a point of the North - South 500KV electricity line has been recently put into operation by Vietnam's Electricity Transmission Corporation. 

The substation is part of the Pleiku - Doc Soi - Danang 500kV transmission line project which was approved by the government to be invested with a total capital of VND 533 billion (~ US$ 30 million), financed by the World Bank's credit.

In addition to providing electricity to Dung Quat EZ, Chu Lai Open EZ and other localities in central provinces, this substation also helps resolve the overloading situation for the two 500KV Substations in Da Nang and Pleiku. 

In order to explore the full capacity of the substation, the Central Power Projects Management Board also installs simultaneously the 220KV transmission lines including Doc Soi – Danang, Doc Soi - Quang Ngai, Doc Soi – Dung Quat ones, and three 220kV substations
located at Dung Quat, Quang Ngai and Tam Ky.

According the design, the capacity of this sub-station is 500/220kV - 2 x 225MVA. Such capacity is high enough to sufficiently provide power for about 10 refineries as big as Dung Quat oil refinery.
