Barakah nuclear power plant
On December 27, 2009, Emirates Nuclear Energy Corporation (ENEC) and KEPCO agreed to build four 1400 MWe Korean (APR-1400) nuclear power units in Barakah, United Arab Emirates. KEPCO carried out the project in partnership with KHNP, KEPCO E&C, KEPCO NF, Hyundai E&C, and Samsung C&T. In accordance with its joint project management agreement with KEPCO, KHNP provided manpower and technical support for construction management, in addition to training and licensing support.

KHNP sent skilled nuclear-power-plant operating personnel and provided services requested by ENEC under an operating support services agreement until the agreement ended on July 20, 2016. KHNP will continue to assign an average of 200 operators and engineers to the BNPP annually and provide requested services for 10 years after the completion of BNPP Unit 4. A consortium of KHNP and Korea Electric Power Corporation Plant Service & Engineering Co. (KEPCO KPS) signed a five-year maintenance contract for the BNPP in June 2019.

Diversification
KHNP plans to expand its new and renewable energy production capacity to 7.6 GW by 2030. The company is installing the world’s largest floating photovoltaic power-generation facility (300MW) on the Saemangeum Seawall in North Jeolla Province. With the city of Ulsan and Hyundai Motor Company, it installed a 6 MW photovoltaic power-generation facility. In 2019 KHNP completed a 19.2 MW onshore wind-power-generation complex in 2019, powering about 16,000 households at the foot of Noraesan mountain near its pumped-storage plant in Cheonsong, Syeongsangbuk-do Province.

New markets
In Romania, KHNP implementing a technical-service project for a radioactive waste repository. The company also strengthened cooperation with nuclear power plant operators in the Czech Republic, Poland, Kazakhstan, and Bulgaria.

Overseas renewable energy
KHNP announced in September 2020 that it had joined a consortium with several South Korean financial institutions. The consortium agreed to acquire 49.9 percent of four large wind farms in the United States.

That year, the company joined Korea Overseas Infrastructure & Urban Development Corp (KIND), S Energy, and Hanyang Electric at the World Trade Center Seoul in a consortium to invest in a solar-power project in Chile. The consortium is promoting a 6.6MW plant in Guadalupe and a 6.4MW plant in María Pinto, both near Santiago, the capital of Chile. KHNP intended to complete construction in 2021 and operate the two plants for 25 years.

US reactor
The US Nuclear Regulatory Commission (NRC) certified KEPCO's APR-1400 in 2019, saying that the NRC found the design fully meeting US safety requirements. According to KEPCO, the APR-1400 was the first "non-US type" reactor design certified by the NRC. In October 2017, European Utility Requirements (an advisory group for European utilities) had approved the APR-1400 reactor design.

Winning a tender in the Czech Republic
On 17 July 2024, KHNP won the tender for the construction of two new units at Dukovany in Czech Republic and will also negotiate an option for the construction of two more units at Temelín. Price for one unit at Dukovany to be about CZK 200 billion.
