KEPCO Freezes Q4 Rates at +5 Won Cap Despite Higher Fuel Costs
KEPCO holds fuel cost adjustment charges at the 5 won ceiling for Q4, masking a calculated need of 7.3 won per kWh.
Key points
- KEPCO freezes Q4 electricity rates by holding the fuel cost adjustment at the 5 won per kWh regulatory ceiling.
- Actual fuel costs require a 7.3 won per kWh adjustment, but the 5 won cap forces KEPCO to absorb the 2.3 won difference.
- KEPCO's consolidated debt with subsidiaries reached 210 trillion won in the first half of the year due to uncapped fuel cost burdens.
Korea Electric Power Corporation (KEPCO) has confirmed that electricity rates will remain unchanged for the fourth quarter, effective from October. The utility will maintain the fuel cost adjustment unit price at the regulatory ceiling of 5 won per kilowatt hour, freezing total consumer rates despite rising input costs.
This decision caps the pass-through of energy expenses to consumers. While KEPCO’s internal calculations indicated a higher necessary adjustment of 7.3 won per kWh, the statutory limit of ±5 won per kWh prevented any increase. Consequently, the basic, electricity, and climate environment rates also remain static, leaving the full burden of fuel cost inflation on the company’s balance sheet.
Fuel cost gap drives accounting deficit
The discrepancy between the capped rate and actual costs stems from elevated fuel prices. The average trade statistics price for bituminous coal, LNG, and bunker C oil resulted in a performance fuel cost of 549.64 won per kilogram. This figure exceeds the standard fuel cost of 494.63 won per kilogram by 55.01 won, creating a structural loss for each unit of electricity sold.
KEPCO has applied the maximum positive adjustment of 5 won per kWh for 18 consecutive quarters since the third quarter of 2022. This prolonged period of capped rates means the utility continues to absorb the difference between market fuel prices and the regulated charge, directly impacting its quarterly earnings and cash flow.
Debt load reaches 210 trillion won
The financial strain from limited rate hikes amid soaring input costs has accumulated into a significant liability. As of the first half of this year, the consolidated debt of KEPCO and its power generation subsidiaries amounted to 210 trillion won. The inability to fully reflect fuel cost fluctuations in consumer rates has been a primary driver of this accumulated deficit.
According to reporting by mk.co.kr, the company’s financial burden is expected to persist as long as fuel costs remain above the standard baseline. The regulatory framework limiting the fuel cost adjustment to a ±5 won range ensures that any excess costs are retained by the utility, further pressuring its solvency metrics and debt servicing capacity.
