- Toshiba Corporation has received an order to supply steam turbines and generators (STGs) for the extension of Vinh Tan 4 coal-fired thermal power plant by state-owned Vietnam Electricity (EVN). The order is from Mitsubishi Corporation of Japan and Doosan Heavy Industries & Construction Co., Ltd. of South Korea, members of the consortium awarded the engineering, procurement and construction contract for the project by EVN. Toshiba will start delivery in January 2018, with commissioning scheduled for 2019.
The STG that Toshiba will supply to the Vinh Tan 4 extension, generate steam at a pressure of over 240 bars, with a reheat steam temperature of 593°C. They are considerably more efficient than theSTGs now in wide use in Vietnam. Toshiba won an earlier contract to provideSTGs for Units 1 and 2 of Vinh Tan 4, now under construction, in April 2014, and started delivery in December 2015. The award of the new contract is based on Mitsubishi and Doosan’s positive evaluation of the technical strength of Toshiba’s STGs and the company’s delivery record.
Commenting on the order, Mr. Takao Konishi, General Manager of the Thermal & Hydro Power Systems & Services Division in 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 straining Vietnam’s power generating capacity, with Southern Vietnam particularly susceptible to shortages. The government is responding with expansion plans to boost electricity supply. So far, Toshiba has supplied STGs for the Vung Ang 1 Thermal Power Plant and the Thai Binh 2 Thermal Power Plant,contributing to securing stable power supply in Vietnam.
Toshiba will reinforce its thermal power plant business, a source of steady income, by globally providing high-efficiency power generation equipment. Toshiba will look to contribute both to the realization of a low-carbon society and to the stable supply of electricity.
