Large power sources including hydro-electricity and thermalpower all have decreased, so the available capacity of the national and northernpower systems is only about 42,000MW and 19,000MW in the afternoon peak, and 39,200MW and 18,000MW in the evening peak, respectively.
Therefore, the EVN has to mobilise thermal power sources running on diesel oil (DO)and fuel oil (FO).
It has also implemented many solutions such as working with theVietnam National Coal - Mineral Industries Holding Corporation Limited(Vinacomin), the Dong Bac Corporation, and the Vietnam Oil and Gas Group(Petrovietnam) to supply coal, gas and oil for power plants.
The group has negotiated with investors of wind and solar power projects that areeligible to generate electricity to the national grid, while coordinating withlocalities in enhancing economical and efficient use of electricity.
More efforts are being made to add new power sources,including negotiations with investors of transitional renewable energy plants.To date, 15 power purchase contracts have been completed with a total capacityof 1,150MW and a temporary price equal to 50% of the price bracket.
However, as of May 21, the EVN had only added 85MW ofelectricity from Trung Nam Thuan Nam solar power to the national grid, while otherinvestors were having to finalise relevant legal regulations.
Meanwhile, it is negotiating to buy electricity from Chinavia the 110kV Shengou - Mong Cai line in May, June and July with a capacity of70MW, and soon completing procedures to sign the power purchase agreement.
The group has also boosted the import of power from Laosthrough the Nam Kong and Nam San hydropower plant clusters./.
