The system marginal price (SMP) for electricity in South Korea stood at around *South Korean won per kilowatt-hour as of March 2025. The South Korean government introduced the SMP ceiling system at the end of 2022, which limits the wholesale price at which Korea Electric Power Corporation (KEPCO) purchases electricity from power generation companies to protect energy consumers during times of price fluctuations. KEPCO is a public institution responsible for the distribution of electricity in South Korea. In the last 10 years, electricity consumed per capita in South Korea has seen a steady increase.
