As the Lee Jae-myung administration’s policy of phasing out coal gathers momentum, earnings pressure has increased at the Korea Electric Power Corporation’s thermal power subsidiaries.

Both companies shifted from operating profit to operating losses compared with the same period a year earlier.

In the same period a year earlier, the system marginal price was 1 per kilowatt-hour 115.6 won.

As this price fell, the settlement prices actually received by power generators also declined.

Although the price of electricity sold to KEPCO fell, fuel costs for coal-fired power generation rose at the same time.

Among power generation 5 companies, Korea South-East Power has the highest share of coal-fired power generation.

Korea South-East Power said that lower unit sales prices, reduced electricity sales volumes and a rising exchange rate led to foreign-exchange losses, including losses on lease translation.

Korea Western Power's performance declined as the closure of coal-fired power plants coincided with temporary suspensions of operations due to fires.
