📊 Doosan Enerbility: Between Changwon Investment and Stock Numbers - 2026.10.20

Well, look who’s here—Onion~! The biggest thing catching the eye in Doosan Enerbility’s world today is the major investment news coming out of Changwon 🔥

Investing 500,000,000,000 KRW in Changwon to expand the nuclear power business

Changwon Special City signed investment agreements totaling 500,000,000,000 KRW with three companies in and outside the region, and Doosan Enerbility is also taking part, investing in expansions to the nuclear power plant manufacturing facility and the new forging and casting business plant at its Changwon site ^[1]. The backdrop is rising power demand driven by the spread of AI data centers, along with the global push to decarbonize. The key point is that facilities related to large nuclear power plants and small modular reactors (SMRs) are included in the investment plans 📈

Changwon City is pushing in the same direction. Its goal is to build an ecosystem connecting manufacturing, testing, and inspection with R&D, drawing on the region’s foundation of around 150 nuclear power companies, with Doosan Enerbility at the center. It has laid out plans to foster the nuclear industry over the next 50 years, with SMRs at the heart, and establish a global manufacturing hub ^[2]. That’s it, that’s it! The whole region feels like it’s in the same boat, doesn’t it?

Engine talk spreads into defense

Doosan Enerbility signed a memorandum of understanding (MOU) with LIG D&A to develop guided-missile engines ^[3]. The signing ceremony was held at Bundang Doosan Tower, and the two companies will cooperate on next-generation guided weapons and aircraft engines. The stated aims are to respond to a rapidly changing security environment and enter the global defense market ^[4]. The phrase to keep an eye on here is “domestically produced engines.” The question is whether technology built up through gas turbines can extend into other fields. Still, an MOU is a starting point for cooperation, not a contract, so it’s difficult to say at this stage how much will ultimately translate into actual sales.

Still, stock numbers are unforgiving

Now for the mood-killing part. According to this table, the closing price on October 20 was ₩62,800, with a change of -5.71%. That’s down from the October 19 close of ₩67,100(+4.19%) the day before. The stock had fallen as low as ₩61,400(-10.88%) on October 15 before rebounding, so recent swings have been quite wide. Even as positive expectations build, the price isn’t moving in step—that’s a defining feature of the market right now. What did I tell you~? Some days, the numbers speak before the news does.

Let’s leave the questions here

There’s still a lot to confirm: whether nuclear and SMR investment will lead to actual orders and earnings, and whether the MOU will turn into defense sales. Onion sees a clear bullish scenario for nuclear power and SMRs, but we also have to remember that for this picture to become reality, orders need to show up in the results. The real question in this story is where expectations turn into numbers ☕
