Siemens to upgrade local steam plant into combined cycle power plant

The contract signing ceremony to supply Siemens equipment to Hiep Phuoc Power Co., Ltd.

This project will increase the plant’s electrical capacity by roughly 780MW to approximately 1,200MW. The modernised plant will be fired with regasified liquefied natural gas (LNG) instead of the oil that has been used to date.

By changing the fuel, deploying modern F-class gas turbines from Siemens, and using the waste heat from the gas turbines to produce electricity, the CO₂ emissions can be cut almost in half for each kilowatt-hour produced on-site. With this project, the customer Hiep Phuoc Power Co., Ltd. will ensure a reliable, secure, and environmentally friendly power supply for Ho Chi Minh City and Vietnam.

The scope of supply from Siemens includes three SGT5-4000F gas turbines, three generators, three heat recovery steam generators (HRSG), related electrical equipment, and the SPPA-T3000 control system. Once the power plant has been upgraded, the waste heat from the gas turbines will be used to generate steam.

The steam obtained will be used to drive the existing steam turbines and generators for electricity production. Recommissioning of the upgraded plant is scheduled for the second half of 2022. To meet the current electricity demand in Vietnam, Hiep Phuoc Power Co., Ltd. will be able to provide around 520MW to the grid by mid-2021 through open cycle operation.

“We are proud to support Hiep Phuoc Power Co., Ltd. to improve the electricity supply situation with an environmentally friendly power plant solution,” said Andreas Pistauer, head of the Asia-Pacific Region within Siemens Gas and Power. “At the same time, the extension to efficient combined cycle technology will diversify the plant’s operational functionality and thus increase the customer’s flexibility.”

Siemens is a leading supplier of combined cycle power plants on Vietnam’s market, with strong reference projects including the Phu My 2-1 and Phu My 3 extensions, as well as orders for the Ca Mau 1 and 2 and Nhon Trach 2 power plants.
