How Electricity Bills Work in Korea (2025)

Korea’s residential electricity billing system is a mix of base charges, tiered usage rates (progressive pricing), and fuel cost adjustments.

Here's how it breaks down:

  1. Base Fee: A small fixed amount based on your household type.

  2. Usage Fee (Tiered System): The more electricity you use, the higher your per-kWh rate gets. This is called the progressive rate system.

  3. Fuel Cost Adjustment: Added or subtracted quarterly, based on global fuel prices. In 2025 so far, this has remained unchanged.

Korea uses different tiers for summer (July–August) and the rest of the year.

● 2025 Summer Rates (July–August)

Usage Rate per kWh
0–300kWh ₩120.0
301–450kWh ₩214.6
451kWh+ ₩307.3

● 2025 Non-Summer Rates (Jan–June, Sep–Dec)

Usage Rate per kWh
0–200kWh ₩93.3
201–400kWh ₩187.9
401kWh+ ₩280.6

Even if two people use the same amount of electricity, their final bill may vary depending on when they used it and which tier they hit. That’s why it’s crucial to track your monthly usage and know which pricing band you're in.

Average Monthly Electricity Cost by Household Size

To know if your bill is reasonable, let’s look at the nationwide average monthly electricity bills in 2025 based on household size.

Household Size Avg. Monthly Bill (KRW)
1 person ₩55,000
2 people ₩75,000
3 people ₩95,000
4 people ₩115,000
5+ people ₩130,000

These figures are annual averages, which means they balance out high-use months (summer and winter) with low-use months (spring and fall).

Actual bills may vary depending on:

  • Air conditioner/heater usage

  • Number of appliances always running (fridge, purifier, etc.)

  • Building type (apartment vs. villa)

  • Eligibility for discounts

Try comparing your bill with the average above. If your 2-person household pays over ₩90,000 every month, it might be worth looking into your usage habits—or checking if you're in a higher tier.


Seasonal Peaks: What to Expect in Summer & Winter

In Korea, electricity use isn't just about how many people live in your house—it’s also about the season.

Summer (July–August)

Air conditioning is the biggest culprit. Most households jump into the 2nd or 3rd tier quickly during these months. For a family of 4, a summer bill can range from ₩140,000 to ₩170,000.

Winter (December–February)

Electric heaters, floor heating systems, and even electric blankets can drive up electricity use. A typical winter bill may reach ₩120,000–₩145,000 or more, especially in poorly insulated buildings.

Spring & Fall (Low Season)

These are the cheapest months, with many households paying only ₩60,000–₩80,000.

💡 Tip: If your summer or winter bill is over 2x your spring bill, you're likely hitting the higher tiers. Time to investigate!


How to Tell If You’re Paying Too Much

Worried that your bill is above average? Here's how to check:

Do this self-check:

  • Is your bill 15–20% higher than the average for your household size?

  • Do you often hit 400kWh or more per month?

  • Are you running a lot of 24/7 appliances? (e.g., fridge, air purifier, water purifier)

  • Do you rarely unplug electronics or use standby power?

  • Are lights or A/C left on longer than needed?

If you answered “yes” to 2 or more, you're likely paying more than you should.

One key thing to check is your monthly usage in kWh. You can find this on your KEPCO bill or in the “KEPCO Smart Billing” app. If you cross into the 2nd or 3rd tier, even just once, your rate jumps sharply.


Smart Tips to Reduce Your Electricity Usage

The good news is, cutting your electricity bill in Korea is possible—even without sacrificing comfort.

Here are easy tips that actually work:

In Summer:

  • Set your A/C to 25–26°C, and use a fan to circulate cool air.

  • Keep blinds closed during the hottest hours to block sunlight.

  • Turn off unused A/Cs when moving between rooms.

In Winter:

  • Use draft stoppers or window film to reduce heat loss.

  • Layer clothing instead of cranking up the heater.

  • Use electric blankets or heated pads sparingly.

Everyday Habits:

  • Plug electronics into a power strip with a switch and turn it off when not in use.

  • Run the washing machine at night if you have off-peak rates.

  • Unplug chargers, TVs, set-top boxes when not needed.

  • Switch to high-efficiency appliances if possible (especially for old fridges or washing machines).

Even one or two changes can save you ₩10,000–₩20,000 per month—over time, that adds up!

💡 Tip: Download the KEPCO app (한전 스마트고지서) to track your usage and set alerts when you're approaching the next tier.

FAQ: Korean Utility Bills Explained

Here are some less obvious but highly relevant questions that foreign residents often ask:

Q1. Do apartment buildings include electricity in maintenance fees?
Sometimes, yes. Some officetels or managed apartments include electricity as part of a lump-sum utility bill. But in most cases, electricity is billed separately by KEPCO. Always ask your landlord when you move in.

Q2. Can I put the electricity bill under my own name as a foreigner?
Yes! If you're the legal tenant, you can call KEPCO (☎123) and change the billing account to your name. You’ll need your ARC and a copy of your lease contract (임대차계약서).

Q3. What happens if I don't pay my electricity bill on time?
KEPCO usually gives a 15-day grace period after the due date. After that, a second notice is issued. If unpaid beyond the second notice, power may be disconnected, and late fees will apply. Always check the bill due date.

Q4. Can I pay my bill with a foreign credit card?
Generally no. KEPCO accepts Korean bank transfers, cash payments at convenience stores, or auto-payment with a Korean credit/debit card. If you don't have one, consider asking your employer or school for assistance.



Electricity bills in Korea can be confusing, but they don’t have to be overwhelming.
Once you understand how the pricing works, how your household compares to the average, and what discounts or tips you can take advantage of, you'll feel much more in control.

Track your usage.
Check your eligibility for discounts.
Apply small changes to your daily habits.

Even as a foreigner, you’re not left out—these systems are here to support you too.

And remember: the best way to save money on your electricity bill is to stay informed and proactive.
