The extension of the Vinh Tan 4 plant – owned by Vietnam Electricity – is currently being carried out by a consortium of Mitsubishi Corporation and Doosan Heavy Industries & Construction.
The 600 MW steam turbines and generators that Toshiba will supply generate steam at a pressure of over 240 bars, with a reheat steam temperature of 593°C.
Toshiba said they are “considerably more efficient than thesteam turbines and generators now in wide use in Vietnam”. Toshiba will start delivery in January 2018, with commissioning scheduled for 2019.
In 2014 Toshiba won a contract to provide the same equipment for Units 1 and 2 of Vinh Tan 4, and started delivery in December 2015.
Takao Konishi of Toshiba’s Energy Systems & Solutions Company said: “Demand for power is growing fast in Vietnam and Toshiba is pleased to help increase capacity. Selection of our steam turbines and generators for Vinh Tan 4 extension is a strong testament to the country’s confidence in the technologies and services which Toshiba has developed over the years.”
Strong economic growth is putting a strain on Vietnam’s power generating capacity, with the south of the country particularly susceptible to shortages and the government is responding with expansion plans to boost electricity supply.
So far, Toshiba has supplied steam turbines and generators for the Vung Ang 1 and Thai Binh 2 thermal plants.
