Quang Ngai power complex will include four 750MW gas-fired combined-cycle power plants in the Quang Ngai and Quang Nam provinces of Vietnam. The project will have a combined capacity of 3GW and will generate power using gas supplied by the Ca Voi Xanh gas field (Blue Whale gas field), which is located approximately 80km offshore of central Vietnam. The total investment in the combined-cycle power plants and the offshore field development is estimated to be $20bn. The $1.78bn first phase of the Quang Ngai project will include the development of the power plants in the Dung Quat Economic Zone (DQEZ). The first plant in the DQEZ is expected to commence operations in the fourth quarter of 2023, while the second plant will commence operations in the second quarter of 2024. The Quang Ngai gas-fired power complex in the DQEZ will cover an area of approximately 85.9ha. The main plant will cover an area of 54.7ha, while the operations and maintenance area will cover 6ha. The DQEZ power complex will also include a port area, pump station and pipeline for supplying cooling water, all of which will cover an area of 25.2ha. The Dung Quat Economic Zone Authority completed site clearance for 25.3ha out of the 54.7ha of the power plant by July 2017. The power plants in the CLEZ will cover an area of 117.7ha. Three of the four plants in the Quang Ngai power complex will be developed by Electricity of Vietnam (EVN). Petrovietnam Exploration Production Corporation (Petrovietnam) will be the main investor in the project.
