"We plan to enter the aging nuclear plant maintenance market by competing with global players such as GE in the U.S. and Siemens in Germany."

In an interview, E2S CEO Woo-sik Choi said the movement to extend the operating life of nuclear plants to as much as 80 years is gaining momentum in the United States. He explained that while the nuclear ecosystems in both the U.S. and Japan weakened after long periods without new nuclear construction, demand for maintenance of aging plants is expected to grow.

E2S is known for localizing major generator excitation systems (ECS) and controllers for control rod drive system power cabinets, which are core pieces of nuclear plant equipment. The company explains that ECS regulates generator output voltage by controlling excitation, and because a failure can lead to a major power event, reliability and safety are critical.

E2S is regarded as one of the few Korean companies capable of challenging a market led by GE, Siemens, ABB, and Mitsubishi. CEO Choi emphasized that E2S can offer comparable quality at roughly one-third of the price of major overseas suppliers. He also noted that global electricity demand is rising rapidly as investment in AI accelerates data center growth, creating new opportunities for power-sector capital investment.

A further strength is that Mir System, E2S's parent company, is one of Korea's leading PCB design and manufacturing companies, supplying boards for power, rail, defense, medical devices, and drones.
