The southern region is facing the threat of a power shortage during the dry season as construction of power plants is behind schedule.

The demand by the region between March and June will increase by 15 percent against recent figures, according to the Vietnam Electricity (EVN).

The south has to rely on supply from the central and northern regions.

The power transmission lines in provinces like Binh Duong, Ba Ria – Vung Tau, Dong Nai and Long An are overloaded, according to a report in the Nguoi Lao Dong (the Labourer) newspaper.

Meanwhile, construction has been slow on many 220 kV power lines and transmission stations such as Nhon Trach, Phu My 2, Vung Tau, My Xuan, Tay Ninh, Ham Tan and Duc Hoa.

In recent years, the demand for electricity for the aquaculture and fruit cultivation sectors has increased significantly.

The consumption of power in the delta's coastal provinces of Ben Tre, Tra Vinh, Soc Trang, Bac Lieu and Ca Mau in 2012, for example, rose by 50 percent against 2011. In 2013, it increased by 49.6 percent against 2012.

The investment in new power projects cannot keep up with demand, according to the EVN.

To ensure supply, the group has told the Southern Power Corporation to work with provinces to find capital to invest in power line projects that serve businesses' production.

Companies and local residents have also been asked to use power efficiently.

Last month, the corporation put into operation Turbine 1 of Vinh Tan 2 Thermopower Plant and Turbine 2 of Hai Phong 2 Thermopower Plant.

It also put into use 48 projects with 500kV, 220kV and 110kV transmission lines that have a total length of 705 km.

The EVN has also asked the National Power Transmission Corporation to ensure the operation of a high-voltage transmission line system and complete construction on key power projects by the end of this month.

The EVN also said that it had been operating gas-fuelled turbines at full capacity.

Several hydropower plants, including Dong Nai and Thac Mo, would soon have enough flood water for operation.-VNA
