PetroVietnam, the initial investor in the project, planned to commission the first unit of the 1,200MW facility in the central province of Quang Binh in June 2015 followed by the second unit in December 2015.
However, the provincial authority said that the power plant construction is due to commence.
Meanwhile, PetroVietnam said that the large scale and complicated technology of the power plant has led to delays.
Vietnamese Prime Minister Nguyen Xuan Phuc said that the Industry and Trade Ministry will work with the two firms for the takeover of the power plant.
Phuc also asked the Ministry to assess alternate source of power in a bid to avoid shortages caused due to the construction delay of the Quang Trach facility, during the 2017-2020 period.
EVN chief administrator Tran Phu Thai was quoted by Reuters as saying: "We are waiting for instruction on the transfer from the Industry and Trade Ministry."
The project, for which only basic work is completed, will use coal as the major fuel to generate 8.4 billion kWh of electricity annually.
Phuc was reported by VietNamNet Bridge as saying that the government has decided to offer EVN with the rights to build the proposed 1200MW Quang Trach thermal power plant in Quang Binh province.
Russia's Inter RAO was earlier selected to research and develop the Quang Trach 2 project.
