Operation of the power system in October 2019 and the tasks for the whole year 2019

Since the beginning of 2019, Vietnam Electricity (EVN) has ensured power supply for the country's socio-economic development, the people's living activities as well as social, political and national defense events. In the first 9 months of 2019, the total produced and imported power output of the whole system has reached 180.52 billion kWh, an increase of 10.4% compared to that of the same period in 2018.

Regarding the operation situation, by the end of September 2019, the weather was dry and hot in many hydropower reservoirs across the country, the amount of water flowing to the reservoir was still very low compared to the average level for many years. In particular, in the Da River’s basin, the amount of water flowing into large reservoirs in the North (Lai Chau, Son La, Hoa Binh) and many hydropower reservoirs in the South Central region was at the lowest level in recent years. Only some reservoirs in the Central Highlands and Southern basins (such as Reservoirs of Serepok, Tri An, etc.,) had to discharge water to ensure the limited water level as prescribed.

By the end of October 2019, the water level of 26/37 EVN hydropower reservoirs was lower than that in the same period in 2018. Currently, the total available capacity of hydropower reservoirs is around 19.67 billion m3, about 7.67 billion m3 lower than that of the same period in 2018 (equivalent to nearly 2 billion kWh of power).

Accumulated power output in the first 9 months of 2019:

+ Produced power amount generated by hydropower plants reached 51.98 billion kWh, a decrease of 18.3% (11.7 billion kWh) compared to the same period in 2018.

+ Produced power amount generated by coal thermal power plants reached 88.05 billion kWh, increasing by 35% (22.8 billion kWh) over the same period in 2018;

+ Produced power amount generated by renewable energy sources (wind, solar, biomass) was 3.51 billion kWh, accounting for about 1.54%, of which solar power output was 2.78 billion kWh.

+ EVN's power loss was 6.62% (more efficient than the expected 2019 target of 6.7%)

Currently, the power output generated by EVN's power plants and its Generation corporations is 100.7 billion kWh, accounting for 55.8% of the total produced power output of the whole system.

In the first 20 days of October 2019, the total produced power output of the system was 13.2 billion kWh, of which 178 million kWh generated by oil-burnt power sources was mobilized EVN.

Regarding the power transmission, in September 2019, the main transmission direction is from the South to the Central and the North in order to ensure safe power supply to the North due to the hot weather in the this region and the Central; at the same time, the highest capacity to release power load from solar power plants was mobilized. In the first 9 months of 2019, the accumulated transmission output reached about 151 billion kWh (an increase of 10% over the same period in 2018). The amount of power transmitted to the South was about 30.4 million kWh/day (equivalent to 10.3% of the South’s power demand).

Regarding the Rooftop solar power program: By the end of September 2019, 15,289 rooftop solar power projects with a total capacity of 249.9 MW were installed. Based on the Draft Decision of the Prime Minister, replacing Decision 11/2017/QD-TTg, which expired from 30 June 2019, on the mechanism of encourage solar power development, the purchase price for rooftop solar power is expected to remain the same.

Some key targets and tasks of EVN in the Fourth quarter of 2019

Many difficulties will face EVN during the implementation of its planned tasks of operating the power system in the last 3 months of 2019, including: (i) Power demand is forecasted to continue increasing dramatically, meanwhile the power system likely has no backup power source; (ii) the water level of hydropower reservoirs is very low, particularly the large ones on Da River whose water level is close to the dead one; (iii) Coal supply for power generation will face extreme difficulties, besides, thermal power plants were mobilized to operate at high capacity in the first 9 months of 2019; (iv) Domestic gas sources have decreased, since October 2019, PM3 gas output continues declining sharply; (v) Oil power sources expected to be highly mobilized in the last 3 months of 2019 will be a big challenge for the Group's financial situation; (vi) The total capacity of renewable energy sources put into operation is expected to continue increasing, exerting negative impacts in safe and stable operation of the power system, etc.

However, with the aim of achieving and exceeding the targets set for 2019, including ensuring power supply and improving production and business efficiency as well as labour productivity; striving for profitable business, preserving and developing capital, the Group has set out some targets for its operation as follows:

- Produced and purchased power amount in 2019 is estimated at 226.4 billion kWh, of which the commercial power output in 2019 is at 211.4 billion kWh, increasing by 9.9% compared to that in 2018.

- In expectation, power output generated by renewable energy sources throughout 2019 is about 5.54 billion kWh (of which about 4.6 billion kWh is generated by solar power sources); Particularly, it is expected that oil sources which require high costs shall be mobilized to produce an output of about 1.56 billion kWh.

- Striving to achieve the planned target of 6.7% for power loss index.

- Improving the index of power access 3 to 5 levels higher than that of 2018, ranked at ≤24/190 countries and economies.

- In 2019, striving that each Power Corporation has at least 2-3 power companies meeting the standards equal to ASEAN 4 power companies.

- Increasing the labour productivity by 10% compared to that of 2018.

- Safe and stable operation of the power system and power market, closely following load situation and weather – hydrological happenings, always ready to response to adverse situations; mobilizing the system’s plant to operate at the highest capacity.
