If every night you turn on the air conditioner, induction cooker, water heater and electric car charger at the same time from 5:30 p.m. to 10:30 p.m., how much money could your electricity bill increase next month?

According to the new widely shared time frame, EVN has changed the way to calculate peak hours with the goal of optimizing national electricity load and reducing evening consumption pressure.
The most notable point lies in abolishing the morning peak frame and consolidating all peak hours in the evening.

NOTABLE NEW ELECTRICITY HOURS

Time frame Time Note
Peak hours 5:30 p.m. - 10:30 p.m. Apply continuously for 5 hours
Normal hours 06:00 - 17:30 and 22:30 - 24:00 Total 13 hours/day
Off-peak hours 00:00 - 06:00 Lowest electricity price

⚡ The biggest change is eliminating the morning rush hour from 9:30 a.m. to 11:30 a.m. This helps businesses produce during the day more easily, but puts extreme pressure on the evening hours when almost every family uses electricity at the same time.

GROUP OF DEVICES THAT CONSUME THE MOST POWER AT PUMP HOURS

Equipment Average capacity Estimated increase in electricity bill if used during peak hours
Air conditioner 1.5HP 1200W - 1500W +150,000 VND to +350,000 VND/month
Kitchen from 1800W - 2200W +120,000 VND to +300,000 VND/month
2500W water heater +80,000 VND to +200,000 VND/month
Electric vehicle charger 1500W - 3000W +200,000 VND to +600,000 VND/month

What surprises many people is that the new time frame almost "hits" the busiest time of the day for Vietnamese families.

WHO IS WORST AFFECTED

• The house has an electric car that charges after work
