Korea Hydro & Nuclear Power

What Korea Hydro & Nuclear Power does

Korea Hydro & Nuclear Power Co., Ltd. (KHNP) is a South Korean state-owned electric power company and the country's largest generator, producing approximately 32.04% of South Korea's total electricity as of December 2025. Founded in 2001 as a spin-off from Korea Electric Power Corporation (KEPCO), KHNP operates a 31,475.51 MW generation portfolio across 152 units: 26 nuclear reactors (26,050 MW) at eight sites including Kori, Hanul, Hanbit, Saeul, and Wolsong; 21 hydro plants (607.48 MW); 16 pumped-storage facilities (4,700 MW); and 70 solar, 1 wind, and 2 fuel cell installations (118.03 MW). Its core nuclear technology stack centers on indigenous APR1400 (1,400 MWe) and OPR1000 (1,000 MWe) Gen III+ reactor designs, with the i-SMR (innovative Small Modular Reactor, ~300 MWe) in development under Korea's SMR Special Act.

KHNP's revenue model rests on four streams: (1) regulated domestic electricity sales exclusively to parent KEPCO (its sole offtake counterparty); (2) international EPC and construction management contracts through "Team Korea" consortia, anchored by the ~$17.6-19 billion Dukovany project in the Czech Republic, the El-Dabaa turbine island work in Egypt, and the $2.85 billion Cernavodă Unit 1 refurbishment in Romania; (3) nuclear fuel cycle services under MOUs with Orano and Framatome; and (4) technology licensing of APR1400/i-SMR designs. The company holds Moody's Aa2, S&P AA, and Fitch AA- credit ratings.

KHNP deploys proprietary AI/digital systems across its fleet, including a generative AI platform co-developed with Naver Cloud (claimed as the world's first for nuclear plant operations), a Digital Twin-Based Hydro-AI Monitoring & Diagnosis (H-AIMD) system, an APR1400 operator support system (TOSS), and EPRI Technology Transfer Award-winning steam generator inspection technology. Geographically, KHNP maintains offices in eight countries — South Korea (HQ, Gyeongju), USA, France, Romania, Poland, Egypt, Russia, and the Czech Republic — and pursues international opportunities via government-to-government agreements across Europe, MENA, ASEAN, and South Asia.

Revenue model

1. Electricity Generation & Sales to KEPCO: KHNP generates approximately 32% of South Korea's total electricity (26,050 MW nuclear capacity as of 2025) and sells all power output to Korea Electric Power Corporation (KEPCO) under a regulated/contracted framework as a state-owned enterprise. This is the primary revenue driver.
2. International Nuclear Construction Contracts: KHNP earns revenue from EPC and construction management contracts for overseas nuclear projects, including the Dukovany project in the Czech Republic (valued at ~$18-27 billion) and El-Dabaa in Egypt. Revenue from these projects flows through 'Team Korea' consortium arrangements.
3. Nuclear Fuel Supply & Services: KHNP procures uranium concentrates, UF6 conversion services, and nuclear fuel cycle services, with MoUs signed with Orano (France) and Framatome (France) covering uranium procurement through conversion and enrichment.
4. Hydropower & Pumped-Storage Operations: KHNP operates 21 hydro plants (607.48 MW), 16 pumped-storage plants (4,700 MW), 70 solar installations (118.03 MW), 1 wind turbine (0.75 MW), and 2 fuel cell units (28.6 MW), generating additional electricity revenue through KEPCO offtake agreements.

Products and services

• Baseload nuclear power generation Generation of baseload low-carbon electricity from KHNP's fleet of PWR (APR1400, OPR1000) and PHWR (CANDU-6) nuclear units; electricity is sold wholesale to parent KEPCO under government-administered tariffs and accounts for the majority of South Korea's nuclear output.
• Hydroelectric power generation Generation of electricity from KHNP's hydroelectric plants (multi-dam fleet including large facilities such as Chungju and others); output is fed into the national grid and contributes to KHNP's combined generation mix.
• Pumped-storage hydroelectric generation Large-scale pumped-storage hydropower facilities operated by KHNP that provide peak-hour generation and grid-balancing ancillary services; integrated with the nuclear fleet to balance baseload output against fluctuating demand.
• Renewable power generation (solar, wind) KHNP-owned and operated solar and wind generation assets contributing to its clean-energy portfolio and to South Korea's renewable targets.
• APR1400 nuclear new-build EPC export Turnkey engineering, procurement and construction of APR1400 (Gen III+, 1,400 MWe PWR) nuclear power plants for foreign governments/state utilities, typically delivered through a Korean consortium including KEPCO E&C and Doosan Enerbility with Korean export-credit financing.
