Korea Hydro & Nuclear Power Co., Ltd(KHNP) is the largest electric power company which generates approximately 26.7% of the total electric power generated in Korea with the noble sense of mission and pride of ‘supplying electric power in a stable manner to enrich the lives of people and to contribute to the growth of the national economy’ as its driving force. KHNP operates 24 units of nuclear plants, 35 units of hydro power plants and 16 units of pumped-storage power plants, and has a total installed capacity of about 27,896MW. In particular, its nuclear power capacity reaches about 22,529MW, leading Korea as the sixth largest nuclear powerhouse in the world.

Amid tightening regulations on carbon dioxide emissions triggered by intensifying global warming, rising energy prices, including oil as well as widespread resource nationalism across the world, nuclear power is considered by many countries as a key energy source for the next generation since 2000.

In this context, in collaboration with the Korean government and relevant organizations, KHNP has been actively carrying out global nuclear power projects around the world such as exporting Advanced Power Reactor 1400 (APR1400), EU-APR SMR(SMART) and providing O&M (Operation and Maintenance) services based on a strong supply chain and project management capabilities accumulated over 40 years of experience in construction and operation of nuclear power plants.
