Vinh Tan 4 Extension Thermal Power Plant successfully grid-connected for the first time

The Vinh Tan 4 Extension Thermal Power Plant (VT4E) is undertaken by a consortium of Power Engineering Consulting Joint Stock Company 3 and Power Engineering Consulting Joint Stock Company 4 for contract management, design appraisal, and construction supervision. The project has been substantially completed, ensuring quality and surpassing the schedule.

On April 22, 2019, the VT4E successfully conducted its first grid connection, surpassing the schedule by 71 days (the planned date as per the contract was July 1, 2019). This milestone marks a significant step towards commissioning the project for commercial operation before October 31, 2019.

VT4E, with an installed capacity of 600 MW, is located in Vinh Tan commune, Tuy Phong district, Binh Thuan province. Vietnam Electricity is the Investor, and the Power Generation Corporation 3/Project Management Board of Vinh Tan Thermal Power Plant is responsible for project management.

The project utilizes existing infrastructure and some shared systems with the Vinh Tan 4 Thermal Power Plant project. It is one of the critical projects of the government, aligned with the Power Development Plan VII, aiming to meet the urgent electricity demand of the southern provinces.

According to the design, the annual electricity output of VT4 will contribute approximately 3.6 billion kWh to the power system. It will operate with the existing Vinh Tan 4 Thermal Power Plant (2 x 600 MW) to ensure a stable power supply for the socio-economic development of Binh Thuan province and the southern provinces.
