(VEN) - To enhance transmission capacity and meet increasing demand in the southern region, the Central Power Projects Management Board (CPMB) under the National Power Transmission Corporation (EVNNPT) is accelerating preparations for a 500kV triple circuit transmission line project.
CPMB Director Nguyen Duc Tuyen said that on January 16, 2017, the prime minister approved the adjustments to the Vietnam National Power Development Planning. This includes: accelerating the rate of progress of the 18-km long Quang Trach-Vung Ang 500kV double circuit transmission line from 2021 to 2025 to the 2016-2020 period; adding the 485-km long Quang Trach-Doc Soi 500kV double circuit transmission line; replacing the Doc Soi-Pleiku 500kV single circuit transmission line by a 200-km long Doc Soi-Pleiku 2 500kV double circuit transmission line and accelerating its rate of progress from the 2026-2030 period to the 2016-2020 period.
With a total length of more than 700 km across nine provinces and cities, the adjustments will involve many localities. In addition, the central region is prone to extreme weather, such as storms and flooding that will greatly affect progress. Therefore, proper preparations are of great importance.
The CPMB is conducting administrative procedures to ensure the progress of investment, such as submitting the feasibility study report for early approval in April 2017, completing the technical design and putting in an estimate for approval in July 2017, and conducting other procedures to be able to start the 500kV triple circuit transmission line project in the last quarter of this year.
Since the beginning of the year, the CPMB has urged consulting units to complete the design documents, correct and supplement records in accordance with regulations in order to shorten the verification and approval process.
According to Vietnam Electricity (EVN), during the 2017-2020 period, electricity demand in the southern region accounted for about 50 percent of the national power system. Because the southern region has no power reserves, EVN will have to generate around five billion kWh of electricity using diesel in 2017, and 8.5 billion kWh in 2018. Therefore, putting the Vung Ang-Doc Soi-Pleiku 2 500kV transmission line into operation will help increase transmission capacity from the north to the center and reduce power shortages in the south.
Tuyen said that the 500kV triple circuit transmission line project is expected to be launched in October 2017 and completed in March 2019. With a large volume of work, it will pose a major challenge for investors and construction contractors.
However, with experience in management of key projects assigned by the EVN and the EVNNPT such as Pleiku-Phu Lam, Pleiku-Doc Soi-Da Nang, the Da Nang-Ha Tinh 500kV double circuit transmission lines and the Pleiku-My Phuoc-Cau Bong 500kV triple circuit transmission line, the CPMB will mobilize all resources to complete the project on schedule.
CPMB says it has offered many solutions to implement the project in an optimal way, forging coordination with corporations, consultants and localities to conduct research and surveys in order to select appropriate plans.
The CPMB has focused on putting in an estimate, dividing up bid packages and conducting contract negotiations since the start in order to save time. In addition, the management board has also implemented multiple tasks, such as coordinating with relevant units to deploy mapping, announcing the project and establishing a council to handle compensation for ground clearance.
According to Tuyen, the CPMB will ask contractors to register detailed plans for executing the work, send more technical staff to the construction sites, handle inquiries and generally supervise and nudge the project forward.
