The importance of the project

Over the years, following the direction of the Prime Minister and the Ministry of Industry and Trade, Vietnam Electricity has completed the negotiation and signed the Power Purchase Agreement for the Van Phong 1 BOT Thermal Power Plant Project, and at the same time assigned to The National Power Transmission Corporation focuses on investing in synchronously connected power grid projects. These are key projects to ensure power supply for the South Central and Southern regions from 2023 onwards.

According to the provisions of the power purchase and sale contract and the BOT contract of the Van Phong 1 BOT thermal power plant project, EVN is obliged to complete the 500kV Van Phong – Vinh Tan transmission line project no later than December 26, 2022. If the project is completed later than this milestone, EVN will have to pay huge expenses every day. At the same time, after 6 months, if it cannot be overcome, the investor has the right to terminate the project and the Ministry of Industry and Trade must buy back the project according to the provisions of the BOT contract. If this happens, it will cause loss, economic damage and affect the reputation of the Government of Vietnam, the Ministry of Industry and Trade, as well as the Electricity of Vietnam with investors.

In addition to releasing the capacity of Van Phong 1 BOT Thermal Power Plant, the investment in construction of synchronous power grid projects to release the capacity of Van Phong 1 BOT Thermal Power Plant is also very important in the operation of the transmission grid. ensure electricity supply and make a significant contribution to the socio-economic development, security and defense for the provinces in the South Central Coast region; clearing capacity of power plants using renewable energy in Khanh Hoa, Ninh Thuan and neighboring provinces; contributing to ensuring electricity supply for the South, creating a strong link between the central and southern power systems, as well as having an important meaning in the economic operation of the national power system.

Concentrating resources to ensure project progress

Speaking at the launching ceremony of joint emulation, Chairman of EVN Member Council Duong Quang Thanh assigned tasks to National Power Transmission Corporation, Central Power Project Management Board, contractors, consulting units and relevant units, must appoint responsible leaders to follow the line to focus on organizing and operating the construction site, mobilizing all resources and better coordinate with localities in accelerating and accelerating progress. The site clearance level as well as the project’s construction schedule, ensure completion on schedule as committed no later than December 26, 2022.

Requesting the units to continue to promote the experience and results achieved through the emulation movements on the transmission grid projects in the past years to continue emulating production labor on the construction works. synchronous power grid project to release capacity of Van Phong 1 BOT Thermal Power Plant, complete energizing on time and ahead of schedule, ensuring quality, efficiency and meeting technical requirements.

Mr. Nguyen Tuan Tung – Chairman of the Board of Members of EVNNPT said: Aware of the importance and urgency of the projects, EVNNPT’s leaders have directed the specialized departments of the Corporation and CPMB to focus on human resources and implementation. synchronous solutions to ensure the progress of completing projects.
