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. Sustainable energy sources in South Korea South Korea imports over ** percent of its energy, which primarily originates from fossil fuels. But as demand continues to rise, the country needs to look for more sustainable options for residents to maintain the same standard of living. One such option is solar energy. Indeed, the government has already invested in solar energy, newly installing multiple megawatts worth of solar power generators yearly. Private solar power installations in South Korea The amount of solar power for private use in South Korea is likely to rise as more people look toward installing their own solar panels to meet their energy needs. Panels that can be attached to the outside railings of apartments as well as on building rooftops are available for private installation. The government has encouraged these efforts through subsidies.

In 2022, petroleum accounted for around **** of all final energy consumption in South Korea, with electricity accounting for nearly another ** percent. According to the source, the share of coal and LNG have both increased compared to the previous year. Electricity consumption in South Korea Electricity made up around ** percent of energy consumption in the country. This is unsurprising as South Korea is renowned for its bright city lights, filled with seemingly never-ending rows of 24-hour cafés and bars on standby for customers seeking anything but sleep. Maintaining this lifestyle, however, demands a constant and reliable source of power as electricity consumption per capita continues to rise. System marginal price (SMP) for electricity Most of the domestic electricity generation in South Korea comes from coal, nuclear, and LNG, much of which is dependent on imports. However, with a high demand for power and a volatile global market, the cost of electricity has started to strain the average household in recent years. As a response, the South Korean government introduced the SMP ceiling system at the end of 2022, limiting the wholesale price at which the Korea Electric Power Corporation (KEPCO) purchases electricity from power generation companies to protect energy consumers when prices fluctuate.

Electricity Trading Market Size 2025-2029

The electricity trading market size is forecast to increase by USD 123.5 billion at a CAGR of 6.5% between 2024 and 2029.

The market is witnessing significant growth due to several key trends. The integration of renewable energy sources, such as solar panels and wind turbines, into the grid is a major driver. Energy storage systems are increasingly being adopted to ensure a stable power supply from these intermittent sources. Concurrently, the adoption of energy storage systems addresses key challenges like intermittency, enabling better integration of renewable sources, and bolstering grid resilience. Self-generation of electricity by consumers through microgrids is also gaining popularity, allowing them to sell excess power back to the grid. The entry of new players and collaborations among existing ones are further fueling market growth. These trends reflect the shift towards clean energy and the need for a more decentralized and efficient electricity system.

By Type Insights

The day-ahead trading segment is estimated to witness significant growth during the forecast period.

Day-ahead trading refers to the voluntary, financially binding forward electricity trading that occurs in exchanges such as the European Power Exchange (EPEX Spot) and Energy Exchange Austria (EXAA), as well as through bilateral contracts. This process involves sellers and buyers agreeing on the required volume of electricity for the next day, resulting in a schedule for everyday intervals. However, this schedule is subject to network security constraints and adjustments for real-time conditions and actual electricity supply and demand. Market operators, including ISOs and RTOs, oversee these markets and ensure grid reliability through balancing and ancillary services. Traders, including utilities, energy providers, and professional and institutional traders, participate in these markets to manage price risk, hedge against price volatility, and optimize profitability.

Key factors influencing electricity prices include weather conditions, fuel prices, availability, construction costs, and physical factors. Renewable energy sources, such as wind and solar power, also play a growing role in these markets, with the use of Renewable Energy Certificates and net metering providing consumer protection and incentives for homeowners and sustainable homes. Electricity trading encompasses power generators, power suppliers, consumers, and system operators, with contracts, generation data, and power station dispatch governed by market rules and regulations.
