Over 300 medium voltage (MV) subprojects and 25 Capacity Upgrading 110 kV projects are being implemented by the power companies under EVNNPC. It is expected that all the projects will be completed by April 2016.

With regard to the distribution grid, the localities with the highest number of projects being implemented to ease the overloaded situation are namely Thanh Hoa (43 projects), Vinh Phuc (25 projects), Nghe An (24 projects), Thai Binh (23 projects) and Quang Ninh (21 projects).

According to the statistics of the EVNNPC, in 2015, the load growth rate in the North was quite high. The provinces with highest growth rate are Bac Ninh, Thai Nguyen, Hoa Binh, Ha Nam (over 20%); followed by Nam Dinh, Thanh Hoa, Thai Binh, Ha Tinh, Hung Yen from 13 to 20%.

The Corporation forecasts that the load growth rates continue to increase this year, causing overloaded situation for the power grid, especially during the hot moths of May, June and July.

For 2015, the EVNNPC completed and energized 34 projects of 220 kV and 110 kV, with a total capacity of substation of 1,058 MVA and total line length of 314 km to meet the load demand.

Currently, in the North, there are 43 substations (substations having 220/110 kV transformers) with 71 220/110 kV transformers. The peak load of the Northern power system is 11,500 MW.

EVNNPC assesses that the redundancy of the power transmission system is not high. Therefore, to build the 110kV grid of standard n-1 by 2020, the prerequisite is that the 500-220 kV substation and transmission line projects will be put into operation as scheduled in accordance with the planning for 2016-2020 period.
