EVNHCMC is prepared for  different scenarios of system operation at peak times during dry season

Organizing power outage drill, arranging backup generators, using live – line working technology if performance on energized grids is needed, etc. are some solutions to be implemented by Ho Chi Minh City Power Corporation (EVNHCMC) to ensure the safe and uninterrupted electricity supply for socio - economic development and people's life in the city at peak months during dry season.

It is forecasted that in 2018, the power sales of Ho Chi Minh City will reach 24,200 million kWh, increasing by 5.71% compared to 2017; the peak capacity is estimated at 4,141 MW, an increase of 7.05% over the same period of 2017.

In the first days of March, 2018, the heat waves occurring in Ho Chi Minh City led to high demand for electricity. In particular, the highest demand occurring on March 15, 2018 got to 74 million kWh, 5.7% higher than the same period in 2017.

By well preparing plans for system operation and power distribution in the dry season, EVNHCMC has ensured the safe and continuous electricity supply for socio - economic development and people's daily life in the city.

Ho Chi Minh City is coming to the peak time of dry season (April and May 2018). Scenarios of electricity security have been rehearsed by the Corporation. The Corporation has also built and got agreement with the Southern Load Dispatch Center on the operation mode of 110 kV power grid, especially to ensure that Tao Dan 220 kV substation supplying electricity the downtown area of ​​the city can operate under 80% of the rated load in the normal mode.

During this time, the Corporation will not cut off electricity to perform repair and maintenance of the power grid. Grid works (if any) will use live - line working technology, flexible and safe load transfer solutions.

In case of power interruption due to unexpected and uncontrollable reasons such as natural disasters and power grid failures, EVNHCMC's member organizations put in place plans to ensure manpower and facilities, adequate equipment and supplies, aiming at resupplying electricity within less than 2 hours.

At present, the power grid in Ho Chi Minh City has a relatively safe contingency, which is 58% as for 220 kV grid, 48% as for 110 kV grid, and 67% as for 22 kV grid. All medium voltage power lines are connected in ring circuits, ensuring n-1 standard.
