South Korea will halve public electric-vehicle charging fees from 11 a.m. to 2 p.m. during the four-day Chuseok holiday from Sept. 24 to 27, while eligible private and business self-consumption facilities will receive a full waiver of electricity usage charges during the same period. The Ministry of Climate, Energy and Environment and Korea Electric Power Corporation, or KEPCO, announced the plan on Sept. 21. The policy is designed to shift EV charging into daytime hours when industrial electricity demand is lower but renewable generation, including solar output, remains relatively steady, helping absorb surplus power and ease grid-management pressures. South Korea had roughly 1.16 million EVs on its roads as of last month. About 102,000 self-consumption charging locations will receive discounts on electricity usage charges of 85.4 won per kWh for low-voltage connections and about 80.2 won for high-voltage connections, although base charges are excluded. Around 18,000 public chargers operated by the ministry and KEPCO will charge half the standard rate. For a 100kW charger, the price will fall from 348.4 won per kWh to 174.2 won. Private operators will also pass on discounts received from KEPCO, although participation and the form of savings may vary. The government expects the holiday measure to have a stronger demand-shifting effect than the spring weekend program, which increased public-charger use during discounted hours by 9.2%. Nineteen mobile chargers will be deployed at eight highway rest stops from Sept. 23 to 27, with priority for vehicles at or below 50% battery charge. The ministry also plans to expand smart-charging infrastructure so EVs can become demand-response resources (assets that adjust electricity use to grid conditions).
