The South Korean government has unveiled a new approach to industrial electricity pricing, aimed at optimizing energy usage in alignment with the rising capacity of solar power. Recognizing that fossil fuel-generated electricity is more prevalent during evening peak demand times, the new plan encourages industrial users to shift their electricity consumption to the daytime when renewable energy sources, particularly solar, are more actively generating power. Consequently, the proposal includes a reduction in daytime rates, set to decrease by an average of 15.4 won per kilowatt-hour, while increasing evening and night rates by 5.1 won, effectively pressuring industries to align their consumption patterns accordingly.

Moreover, the plan provides specific incentives during the spring and autumn weekends and public holidays, offering a substantial 50% discount on electricity rates from 11 AM to 2 PM. This change aims to mitigate wastage of energy typically experienced during these off-peak periods, ensuring that the industrial sector efficiently utilizes available capacity without over-reliance on fossil fuels. The adjustments will primarily be applicable to industries with a contracted capacity of over 300 kilowatts, such as semiconductor, steel, and automotive manufacturers, and are scheduled to come into effect on the 16th of next month.

In addition to changes for industrial rates, the proposal introduces adjustments to existing time-of-use billing structures, aiming to redistribute costs related to peak usage times that traditionally favored fossil fuels. The highest rates will now be applied in the evening hours of 6-9 PM, shifting from the previously highest morning and early afternoon periods. This revised pricing structure, aimed at promoting a more sustainable energy economy in line with South Korea’s renewable energy goals, will enter into effect from June 1 and is set to be reviewed and possibly extended based on industrial adjustment participation over the next five years until 2030.
