Expensive electricity bills during this period may not be strange because the hot weather makes you have to use electrical appliances more often than usual. Of course, your electricity bill may be higher than usual, leading to the question of why “the electricity bill is expensive”. Let’s see what causes expensive electricity bills, how to calculate the electricity bill, and how much electricity each electrical appliance uses, including measures to reduce electricity bills from the government here.
Why is electricity expensive?
First, we need to understand why electricity is expensive. The Electricity Generating Authority of Thailand calculates electricity fees on a progressive basis. The more you use, the more you pay. The variable of the higher electricity bill is the increased electricity units used. This is because the hot weather makes it possible to use some electrical appliances more than usual, such as air conditioners, fans, or refrigerators, which results in more electricity usage than usual.
Electrical appliances that cause expensive electricity bills
Most houses with high electricity bills have the following electrical appliances:
- Air conditioner and compressor
- Air purifier
- Water fan
- Refrigerator
The reason why the air conditioner is still on but the electricity bill is higher is that the compressor works harder. After all, the hot weather causes the electricity usage to increase faster. As for the refrigerator, if the refrigerator is opened frequently, it will consume more electricity. During the Work From Home period, storing a lot of items in the refrigerator will also consume more electricity. (Even though it is an energy-saving refrigerator, it must store no more than 5 bottles of drinks to pay the advertised annual price.)

Why are electricity bills expensive in summer?
The weather is getting hotter and the house is getting hotter, causing each house to use more cooling appliances, such as air conditioners and refrigerators. According to data from the Metropolitan Electricity Authority, the average electricity usage per household user during April-June is higher than in other months of the year, which is consistent with the change in average temperatures that are higher throughout the year.
Electricity prices rise due to FT increase
Ft stands for Float time, which means the floating cost of electricity production that the Electricity Generating Authority of Thailand cannot control, such as fuel prices, inflation rates, foreign exchange rates, etc., according to different periods used as a framework for calculation.
Most recently, the Energy Regulatory Commission (ERC) has resolved to fix the electricity price for September-December 2024 at 4.18 baht per unit, or the Ft value at 39.72 satang.
Government electricity bill reduction measures
The Cabinet meeting approved in principle measures to reduce the burden of energy costs for the public, providing a 19.05 satang/unit discount on electricity bills for residential electricity users who use no more than 300 units/month. The implementation period is May-August 2024 (4 months).
