Korea Power Exchange

What Korea Power Exchange does

Korea Power Exchange (KPX) is a non-profit special corporation established on April 2, 2001 under the Electricity Business Act, designated as Korea's sole electricity market operator and power system operator. The organization operates independently of all power companies including KEPCO, providing fair and transparent electricity trading, 24/7 real-time grid monitoring, demand forecasting, and long-term power supply-demand planning. As of December 2025, KPX serves 7,559 market participants including 6 KEPCO subsidiaries (85,209 MW), 26 general power generation companies (30,087 MW), 7,355 renewable energy generators (14,109 MW across solar, hydro, wind, bio, fuel cells, and marine energy), and 14 direct purchasers — collectively representing 146,166 MW of registered capacity.

KPX's technology stack centers on the Central Power Control Center (중앙전력관제센터) for real-time grid monitoring, the Electricity Trading System (전력거래시스템) for bidding/price determination/settlement, and EPSIS (Electric Power Statistics Information System) for market data. Adjacent platforms include the REC (Renewable Energy Certificate) Trading System, Demand Resource Trading Market, Small-scale Power Brokerage Market (for distributed energy and direct PPAs), and the Hydrogen Power Generation Bidding Market. The organization runs a Power Data Curation Service exposing public APIs for SMP, REC, and demand-response data, and operates official Android/iOS mobile applications. AI-based demand forecasting is used for supply-demand balancing and load prediction via a dedicated AI Innovation Division (AI혁신단).

KPX's business model is fee-based and non-profit: revenue comes from market transaction fees on electricity clearing and annual membership dues from the 7,559 member companies, with fee schedules set by board resolution and regulatory oversight under the Electricity Business Act. Capital is government-funded and governance is member-based. Geographic scope is domestic (South Korea), with regional offices supporting Gyeonggi, Chungbuk, and Jeju operations in addition to its Naju Innovation City headquarters. The organization pursues ESG commitments including a 37.4% institutional greenhouse gas reduction target, K-RE100 renewable procurement, ISO 14001, and ISMS-P (ISMS-P-KISA-2019-023) certifications.
