Electricity bill breakdown — homes
A home bill has six lines: basic charge, tiered energy charge, climate charge, fuel adjustment, VAT and the power industry fund.
Default 492 kWh, July: KEPCO residential average use per customer (July 2026, sales ÷ customers). It is a summer month with air conditioning, so it runs higher than spring or autumn.
