The contract signing ceremony was attended by representatives of EVN leadership, leaders of the Project Management Board 3 (EVNPMB3); lenders AFD, KfW, EIB (part of a consortium including AFD, CDP, Propaco, KfW, EIB, JICA) and the consortium of contractors Voith Hydro Shanghai and Powerchina Zhongnan.

Contract Package No. 01TB-BA – Supply of Electromechanical Equipment for the Bac Ai Pumped Storage Hydropower Project is the main equipment supply package of the project, selected through an open international bidding process. The contractor selection process was conducted in compliance with state bidding regulations and the requirements of the lending institutions. The consortium of Voith Hydro Shanghai and Powerchina Zhongnan, meeting the capability and experience criteria, was awarded the contract valued at 4,462.603 billion VND, with a contract duration of 51 months, aligning with the overall project timeline.

The Bac Ai Pumped Storage Hydropower Project in Khanh Hoa Province is Vietnam's first pumped storage hydropower project, included in the national power development plan for the period 2021–2030 with a vision to 2050. The EVN Board of Members approved the investment project, which includes four units with a total capacity of 1,200 MW. Funding sources for the project include equity and loans arranged by EVN from the German Development Bank (KfW) and the European Investment Bank (EIB).

Once operational, the Bac Ai Pumped Storage Hydropower Project will serve as a peak power source for the grid, helping to reduce load curve discrepancies by utilizing pumped storage capacity during off-peak hours and generating power during peak hours, as well as providing frequency regulation and reactive power compensation for the system.
