From April 22, 2026, Decision 963\/QD-BCT will begin applying a new timeframe for hourly electricity pricing (TOU \u2013 Time of Use), while Circular 60\/2025\/TT-BCT, effective from December 2, 2025, stipulates how to apply electricity tariffs to each customer group.<\/p>\n\n\n\n

This does not mean a uniform increase in electricity prices. However, for manufacturing businesses that consume a lot of electricity, especially those operating heavily in the evenings or running continuously 24\/7, electricity costs could change significantly if operating plans are not adjusted.<\/p>\n\n\n\n

1. How have peak hours changed?<\/h2>\n\n\n\n

According to Decision 963\/QD-BCT, peak hours have been adjusted to focus more heavily on the evening \u2013 the time when electricity demand is high but solar power generation is low. Specifically:<\/p>\n\n\n\n

Time slot type<\/td>Monday to Saturday<\/strong><\/td>Sunday<\/strong><\/td><\/tr>
Old<\/td>New<\/td>Old<\/td>Fat<\/td><\/tr>
Off-peak hours<\/strong><\/td>0h-04h, 22h-24h<\/td>00:00 \u2013 06:00<\/td>0h-04h, 22h-24h<\/td>00:00 \u2013 06:00<\/td><\/tr>
Normal hours<\/strong><\/td>4:00 AM - 9:30 AM, 11:30 AM - 5:00 PM, 8:00 PM - 10:00 PM<\/td>06:00 \u2013 17:30 and 22:30 \u2013 24:00<\/td>4 AM - 10 PM<\/td>06:00 \u2013 24:00<\/td><\/tr>

The goal is to balance the national power grid load and optimize power generation operation.<\/p>\n\n\n\n

2. Scope of Application<\/h2>\n\n\n\n
    \n
  • The following entities are required to apply the time-of-day electricity pricing system:<\/li>\n\n\n\n
  • Electricity buyers using electricity for production and business purposes are supplied with electricity through dedicated transformers of 25 kVA or more, or have an average electricity consumption of 2,000 kWh\/month or more for three consecutive months;<\/li>\n\n\n\n
  • Electricity retailers in industrial parks and clusters;<\/li>\n\n\n\n
  • Electricity buyers purchase electricity for retail sale outside of residential use in commercial-service-residential complexes (factories operating 2-3 shifts, cold storage, logistics, shopping malls, etc.).<\/li>\n\n\n\n
  • Less affected groups: Households, Small businesses, Small offices<\/li>\n<\/ul>\n\n\n\n

    3. What are the actual impacts?<\/h2>\n\n\n\n

    While average electricity prices have decreased during business hours, they have increased at night, directly impacting factories and businesses that operate 24 hours a day.<\/p>\n\n\n\n

    For example, a food processing machine operates 24 hours a day:
    \u2013 Power consumption: 5,000 kWh\/day
    => 150,000 kWh\/month, Approximately 400 million VND\/month in electricity bills.<\/p>\n\n\n\n

    Before the change:<\/strong>
    \u2013 Peak consumption: 1,800 kWh\/day
    \u2013 Normal consumption: 2,000 kWh\/day
    \u2013 Off-peak: 1,200 kWh\/day
    \u2192 Cost: ~391.8 million\/month<\/td>    		After the change:<\/strong>
    \u2013 Peak consumption: 2,200 kWh\/day
    \u2013 Normal consumption: 1,800 kWh\/day
    \u2013 Off-peak: 1,000 kWh\/day
    \u2192 Cost: ~413.4 million\/month<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Difference: +21.6 million\/month \u2192 Nearly 260 million\/year<\/p>\n\n\n\n

    4. What can businesses do?<\/h2>\n\n\n\n
      \n
    • Shifting maximum load: Move the most energy-intensive processes to the 0h-6h timeframe. Make the most of Sundays for urgent orders or mass production.<\/li>\n\n\n\n
    • Upgrade to high-performance equipment while implementing comprehensive energy-saving measures.<\/li>\n\n\n\n
    • Install solar panels, integrating storage for daytime use and generating power at night during peak hours.<\/li>\n<\/ul>\n\n\n\n

      The issue isn't just about using less electricity, but about using electricity more efficiently throughout the day.<\/h3>\n\n\n\n
