The power demand will rise sharply in the second quarter as a result of hot weather. To ensure safe and uninterrupted power supply for customers, Southern Power Corporation (EVNSPC) has developed power supply plans based on construction investment solutions in combination with power supply regulation plans.

According to EVNSPC, in 2019, the largest utilization capacity is forecast at 11,570 MW, an increase of 10.93% compared to 2018. The demand for electricity consumption is expected to rise continuously during the three-month dry season (April to June). High loads will be seen in such localities as Dong Nai, Binh Duong, Ba Ria - Vung Tau, Long An, Tay Ninh, Binh Phuoc and Ben Tre. The increased load during the dry season may give rise to load overcapacity of 220 kV transformers in these areas.

To ensure safe, stable power supply, at the end of the first quarter of 2019, EVNSPC put into operation six 110-kV transformer stations with a total installed capacity of 263 MVA. In addition, 21 power companies in southern provinces and cities urgently operated 22-kV stations to connect to 110-kV stations when they are put into operation.

For fast-growing areas in southern key economic zones such as Binh Duong, Long An, Tay Ninh, Dong Nai and Binh Phuoc provinces, EVNSPC has anticipated load demands and built switching plans for 110kV power stations for each province in 2019. The corporation has also coordinated with provincial departments of industry and trade in checking and supervising electricity conservation by local users; worked with 110kV customers on power supply solutions, load regulation and power saving; effectively carried out Demand Side Management (DSM) implementation plans, reduced the power loss index according to the System Average Interruption Duration Index (SAIDI) to 306 minutes.

Particularly, province-based power companies have actively coordinated with the Departments of Industry and Trade to submit their annual and monthly power supply plans to Provincial/Municipal People's Committees for approval; quickly supplied electricity to customers, worked with big customers to capture load demand and sign agreements on power supply, load regulation and power conservation solutions to ensure safe, continuous power supply; and reviewed and analyzed seasonally and locally typical loads to figure out priority plans for critical loads to serve basic needs of the people.

They have strengthened the protection of high-voltage grids and prevention of flooding and storm impacts; worked closely with local authorities to carry out information and communication to this effect; and continued to implement solutions to reduce incidents and improve supply reliability.

In addition, in April 2019, EVNSPC hosted the Electricity Conservation Festival 2019 in Tay Ninh province; developed power supply plans for political, cultural and social events and people's activities during National Liberation Day and May Day holidays.

EVNSPC’s March and first-quarter business report showed that the electricity output was 6.7 billion kWh in March, representing a year-on-year growth of 11.66%. The average daily output was 217.39 million kWh of electricity, with the biggest daily output of 229.5 million kWh, 10.6% higher than the same period of last year. In the first quarter, the corporation’s electricity output was 17.6 billion kWh, an increase of 10.99% over the same period of last year.

Commercial electricity was 5.708 billion kWh in March, up 14.44% from the previous month and 11.14% over the same period of 2018. In the first quarter, the total commercial electricity output was 16.593 billion kWh, up 10.56% year on year in 2018 and equal to 22.62% of the full-year plan.

Regarding its investment, renovation and upgrading of the power grid, EVNSPC has started construction of eleven 110-kV power grid projects and completed switching on six 110-kV power grid projects with 17 km of new lines and 269 MVA of total additional 110kV stations.

In addition, EVNSPC has put into operation 79 distribution grid projects, including the construction of 166 km of medium voltage lines, the upgrading of 83 km of medium voltage lines, the construction of 1,848 km of low voltage lines, and the upgrading of 797 km of low voltage lines, bringing the total capacity of distribution stations to 65 MVA.
