Siemens Has Built Vietnam’s Largest Privately Operated Power Plant

Siemens Power Generation (PG) built Vietnam’s largest privately operated power plant as a turnkey project in the Phu My industrial park. The plant was released to the operating consortium comprising British Petroleum (BP), Sembcorp and Kyushu Power / Nissho Iwai in an opening ceremony on April 3, 2004. The consortium will operate Phu My 3 for 20 years. The plant is the country’s first power plant that was built as a Build-Operate-Transfer (BOT) project. Siemens PG secured the contract to build the combined cycle power plant from BP in 2001. Siemens also has a maintenance agreement for the plant covering a 12-year period.

The Phu My 3 combined cycle power plant, located about 70 kilometers southeast of Ho Chi Minh City, constitutes a significant milestone in the history of Vietnam’s power supply. It will make a major contribution toward alleviating the country's power shortage. Since January 2004, Phu My 3 has been providing approximately 720 megawatts of power to the grid, which is operated by the state-owned power supplier Electricity of Vietnam (EVN) under the terms of a long-term supply agreement. The combined cycle power plant, which is fired with natural gas from two newly developed offshore gas fields, is operated in base-load duty.

The Siemens PG scope of supply included two V94.3A gas turbines with associated auxiliary systems from the PG manufacturing plant in Berlin, one steam turbine and three generators from Muelheim, the entire electrical equipment and a Teleperm XP instrumentation and control system. The two gas turbines were synchronized with the grid on schedule in late August 2003. The steam turbine was connected to the grid for the first time in November 2003.

At the same location, Siemens PG had already built the gas turbine power plant Phu My 2.1 Extension for EVN. This plant, which is also fired with natural gas, is equipped with two V94.2 gas turbines and two air-cooled generators. This unit has been providing approximately 300 megawatts of power to the Vietnamese grid since early 1999. The total installed power plant capacity in Vietnam currently amounts to approximately 8,250 megawatts.
