At 23:15 on January 27, 2019, after nearly 2 months of shutdown, the overhaul of GT12 unit was officially handed over to the Load Dispatch Center (A0) for operation, surpassing the delivery schedule by 4 days.

In 2018, Phu My Thermal Power Company had to carry out 07 major repair projects, among which the overhaul of GT12 unit at Phu My 1 Power Plant was conducted in the last months of 2018 and completed around the days before the Lunar New Year celebration, marking the arrival of the Year of the Pig.

To ensure quality and expedite the completion of the GT12 unit overhaul at Phu My 1 Power Plant, Phu My Thermal Power Company collaborated with EVNGENCO3 Power Plant Services Company (EPS) to work in two shifts per day in order to shorten the schedule. This involved implementing various improvement and equipment upgrade projects to enhance the available capacity and efficiency of the unit, such as replacing hot gas path components to extend the maintenance cycle, installing additional exhaust pipes in the turbine cooling air intake, installing a purge air system on the gas and oil fuel lines to improve reliability during fuel switching. Particularly, together with the MHPS contractor, the successful replacement of the DCS Diasys UP/V control system with Diasys Netmation for Boiler 12 was accomplished.

After nearly 2 months of continuous work and effort, each equipment was checked, maintained, and put into trial operation and testing, meeting all technical requirements. Following the 6-day hot trial period, the GT12 unit was officially handed over to the National Load Dispatch Center for operation and exploitation at 23:50 on January 27, 2019, 4 days ahead of the approved schedule. The shortened downtime for repair allowed for the quick restoration and operation of the unit, contributing to the increased electricity production for the company, meeting the electricity demand during the dry season of 2019, and ensuring the national energy security.

To achieve the above results, in addition to the hard work and dedication of each employee in the operational and repair departments of Phu My Thermal Power Company and EPS Company, we must also acknowledge the deep concern and timely guidance of the Company's Leadership Board throughout the project to ensure the quality and timely completion of the maintenance work, contributing to the successful fulfillment of the company's tasks in 2019.

Phu My 1 Thermal Power Plant is one of the four power plant clusters under Phu My Thermal Power Company, which started commercial operation on April 22, 2002. The accumulated electricity production of Phu My 1 Power Plant until the end of February 2019 reached approximately 124 billion kWh. The plant utilizes a combined cycle gas turbine technology with a designed capacity of 1,090 MW, operating in a 3-3-1 configuration. It consists of three gas turbines (M701F) with a capacity of 240 MW each, three heat recovery steam generators, and one steam turbine (TC2F-40.5) with a capacity of 390 MW.
