Daily News Briefing (2026-07-12)

At a glance, the power plant industry all looks the same: boilers, turbines, transmission, maintenance. But the parts where the money sticks and the parts where technological edge remains are very different. The core reality of Korea’s power plant industry is this: it is strong in large-scale nuclear, steam turbines, and maintenance, while the next wave—offshore wind, H-class gas turbines, and SMRs—still has major gaps to fill.

If you do not recognize that difference, both the numbers and the companies start to blur together. Doosan Enerbility, KEPCO KPS, KHNP, BHI, Doosan Fuel Cell, S-Fuelcell—familiar names, right? But if you ask who is structurally better positioned, the answer is simpler than it looks. Some companies make money from already proven equipment and maintenance, while those still trying to close technology gaps, quite literally, have a long list of homework left.

In the end, the money lasts longer on the operating side than on the equipment side

The power plant value chain runs long, starting with resources/materials and moving through power generation_upstream, power generation_midstream, power generation_downstream, then energy storage, transmission & distribution_transmission grid·substations·distribution grid·smart grid, retail/consumption, support services, and all the way to power plant maintenance/MRO. What grabs attention at the start is always the big-ticket equipment: nuclear main equipment, steam turbines, BOP, and the like. But on the ground, operations and maintenance make money for much longer than installation does.

In the power plant industry, the highest-quality profits come not from equipment that gets delivered once and is done, but from recurring-revenue segments like power plant maintenance and O&M, where KEPCO KPS and Doosan Enerbility have staying power. Why? Because when a power plant stops, the losses show up immediately. So yes, the company that built the equipment matters—but in the end, what customers hold onto is the side that keeps it running without breakdowns and carries out scheduled preventive maintenance on time. Industry insiders don’t fail to understand this—they understand it all too well.

Korea’s clear strengths today are steam turbines and power plant equipment (BOP), power plant maintenance and O&M, large nuclear reactors (APR1400), and nuclear components and heavy castings/forgings. Its weaker axes are offshore wind systems, large gas turbines (H-class), hydrogen/ammonia co-firing turbines, SMRs, and spent nuclear fuel/decommissioning. What’s good should be called good. Doosan Enerbility and BHI deserve recognition in steam turbines/BOP and nuclear components/heavy castings and forgings. The same goes for the APR1400 led by KHNP and Doosan Enerbility. Maintenance and O&M, where KEPCO KPS and Doosan Enerbility are firmly positioned, is a card Korea genuinely holds in its hand. By contrast, offshore wind systems show a gap of 3. That doesn’t just mean Korea is weak. It means control of the value chain is still far away. H-class gas turbines, hydrogen/ammonia co-firing turbines, SMRs, and spent fuel/decommissioning all show a gap of 2. Korea can catch up, but calling it a leader today would be overstating it. Doosan Fuel Cell and S-Fuelcell clearly have a presence in hydrogen fuel cells, but it would be a mistake to immediately stretch that into overall competitiveness for entire power plants. Fuel cells and large central power generation prime equipment are simply different games. Table below: Domestic vs. global TRL (technology readiness level 1–9) by technology, and key companies Technology Domestic Global Assessment Key companies Gas & Steam Turbines Large gas turbines (H-class) 7 9 Catching up · Gap 2 Doosan Enerbility This is a power generator that compresses air, burns it with fuel, and uses the resulting high-temperature, high-pressure gas to spin a massive turbine and generate electricity. It is roughly like taking a jet engine from an airplane, laying it on the ground, and scaling it up for power generation. The operating principle is the Brayton cycle: air is strongly compressed by a compressor (compression), fuel is burned in the combustor to expand the volume (combustion), and the expanding gas pushes the turbine blades (expansion). The key lies in superalloys and cooling/coating technologies that can withstand flames above 1,500°C, which is why only a handful of global players such as GE, Siemens, and Mitsubishi can build them. Korea became the fifth country to independently develop one through Doosan. At present, Korea is in the stage of demonstrating domestic H-class models (270MW, 380MW) at combined-cycle plants in Gimpo and Boryeong while building an export track record. Hydrogen/ammonia co-firing turbines 4 6 Catching up · Gap 2 Doosan Enerbility, KEPCO This is the technology of blending hydrogen or ammonia into a gas turbine instead of relying solely on natural gas, using fuels that do not emit carbon dioxide when burned. The goal is to start by mixing in 30–50% and gradually move toward 100% hydrogen, turning power plants into “carbon-free” facilities. In principle, hydrogen’s flame propagation speed is nearly eight times faster than natural gas and its flame temperature is higher, so the real battleground is combustor design that can prevent flashback and control surging nitrogen oxide (NOx) emissions. Ammonia (NH3) is discussed because it is easier to transport and store as a liquid hydrogen carrier, but its combustion is difficult in its own right, so deployment begins with pulverized coal co-firing. In Korea, Doosan is developing a 30% hydrogen co-firing combustor, while KEPCO’s generation subsidiaries are pushing ammonia co-firing demonstrations in Boryeong and Samcheonpo. Steam turbines and power plant equipment (BOP) 8 9 Solid · Gap 1 Doosan Enerbility, BHI This refers to the traditional power generation method of boiling water with heat from burned fuel to create high-pressure steam that spins a turbine, along with the supporting auxiliary equipment around it such as boilers, heat exchangers, and condensers—BOP, or Balance of Plant. The principle is the Rankine cycle: water is boiled to create high-pressure steam (heating), the steam does work in the turbine (expansion), then it is cooled back into water in the condenser (condensation) and circulated again by a pump. In combined-cycle plants, the gas turbine’s exhaust heat—around 600°C—can be recovered through an HRSG to generate additional steam and power, lifting total efficiency to around 60%. In Korea, Doosan supplies the steam turbine body itself, while BHI and others supply BOP items such as HRSGs and condensers, giving the country stable competitiveness. Power plant maintenance and O&M 8 8 Solid · Gap 0 KEPCO KPS, Doosan Enerbility This is the maintenance business that inspects and replaces parts and manages performance so power plants can keep running reliably for long periods without stopping. If the manufacturer is the carmaker, this is the repair shop responsible for lifetime inspections and parts replacement. Since power generation equipment is used for 30 to 60 years once built, scheduled maintenance—such as disassembling and inspecting turbine blades and combustors—keeps recurring at fixed intervals. More recently, predictive maintenance using sensor data and digital twins has raised the value-added of this business. KEPCO KPS handles maintenance for most domestic power plants and is expanding into the Middle East and Southeast Asia. Nuclear Large nuclear reactors (APR1400) 9 9 Solid · Gap 0 Doosan Enerbility, KHNP These are large nuclear power plants that generate electricity by using the heat released when uranium nuclei split in two after being struck by neutrons, boiling water into steam and using that steam to spin a turbine. Because 1 gram of uranium produces energy roughly equivalent to about 3 tons of coal, these plants can supply large-scale electricity around the clock with very little fuel. Korea’s APR1400, a 1,400MW-class reactor, is regarded as world-class in safety, construction cost, and schedule discipline. Four units were exported to Barakah in the UAE and are all now in operation, and Korea also secured a foothold for entering Europe by being selected in 2024–2025 as the preferred bidder for the Czech Republic’s new nuclear project. Small modular reactors (SMRs) 5 7 Catching up · Gap 2 Doosan Enerbility, KHNP These are next-generation small nuclear reactors built as modules—typically under 300MW—like factory-made Lego blocks that are assembled on site. Their smaller size allows them to be cooled safely through natural circulation alone, shortens construction time, and makes them suitable for remote regions or dedicated power supply for electricity-hungry data centers. The core idea is to lower costs by mass-producing standardized units in factories rather than pouring everything in concrete on site. U.S. startups NuScale and X-energy are ahead, and Doosan is catching up by supplying them with key components. Korea is also developing its own “i-SMR,” targeting standard design approval by 2028. Nuclear components and heavy castings/forgings 9 9 Solid · Gap 0 Doosan Enerbility, BHI This is the manufacturing technology for critical components such as reactor pressure vessels and steam generators, where steel blocks weighing hundreds of tons are shaped as single pieces through casting and forging. Forging means heating metal and compressing it with giant presses to densify its internal structure, making it far stronger than cast metal and essential for nuclear parts that must withstand high pressure and radiation. Because even tiny defects are unacceptable, the field requires ultra-large presses exceeding 10,000 tons and highly advanced machining and inspection capabilities. Globally, only a handful of players can do it, including Doosan in Korea, JSW in Japan, and a few firms in France. Doosan is now receiving global orders for these ultra-large forging facilities as both SMRs and large nuclear reactors regain momentum. Spent nuclear fuel and decommissioning 6 8 Catching up · Gap 2 KHNP, KEPCO KPS This covers the technologies for safely cooling, storing, and handling spent nuclear fuel, as well as dismantling end-of-life nuclear plants without radioactive contamination. Even after removal, spent fuel continues to emit heat and radiation for a long time, so it is first cooled for years in water (wet storage) and then transferred to metal or concrete casks (dry storage). Decommissioning is a decades-long process involving remote cutting and decontamination of radioactive areas before restoring the site. Korea is building experience through the decommissioning of Kori Unit 1, the country’s first commercial nuclear reactor, while also facing the urgent challenge of securing disposal facilities as temporary on-site storage nears saturation. Renewables Solar cells and modules 7 9 Catching up · Gap 2 Hanwha Solutions, HD Hyundai Energy Solutions These are solar panels (modules) made by connecting multiple plates (cells) that convert light into electricity using the photoelectric effect, where photons from sunlight strike a silicon semiconductor and knock electrons loose, creating current. A single cell produces only a small amount of electricity, so dozens are connected in series and parallel to raise output. The competitive focus is on next-generation structures such as TOPCon and HJT that reduce light loss and improve efficiency, as well as perovskite tandem technology that stacks two different materials to widen the absorption wavelength range. Hanwha is building a large local production base in the U.S. called Solar Hub to differentiate itself amid China’s low-cost volume offensive and America’s protectionist trade environment. Offshore wind systems 5 8 Caution · Gap 3 Doosan Enerbility, CS Wind, LS Cable & System This is the technology of installing giant wind turbines at sea, using the kinetic energy of the wind to turn blades and then a generator to produce electricity. Winds offshore are stronger and more consistent than on land, so output is higher, but the civil engineering and power transmission challenges are tougher because foundations must be installed tens of meters below the sea and electricity must be brought ashore through subsea cables. In the deeper waters of the East Sea, floating structures are being pursued instead of fixed-bottom foundations. Europe still leads in the turbine body itself through players such as Vestas and Siemens Gamesa, while Korea has strengths in towers (CS Wind), substructures (Doosan, Seah), and subsea cables (LS Cable & System). Large-scale projects such as Donghae 1 and Southwest Sea are being rolled out in phases. Hydrogen fuel cells 7 8 Solid · Gap 1 Doosan Fuel Cell, S-Fuelcell These are devices that generate electricity directly through the chemical reaction of hydrogen and oxygen, without combustion. Instead of burning fuel, they use an electrochemical reaction: hydrogen (H2) releases electrons to create current, and those electrons then combine with oxygen to form water (H2O)—essentially the reverse of water electrolysis. If a battery merely stores previously charged electricity, a fuel cell keeps generating fresh electricity as long as hydrogen is supplied. Because the only byproduct is water, it is clean, and because it can generate power 24 hours a day regardless of the weather, it is well suited for distributed generation. Korea, led by Doosan Fuel Cell and S-Fuelcell, is a global leader in power-generation fuel cell deployment, and government CHPS auctions are broadening the demand base. Water electrolysis (green hydrogen) 5 7 Catching up · Gap 2 Doosan Enerbility, Hanwha Solutions This is the technology of splitting water with electricity generated from renewable energy to produce hydrogen. It uses the basic principle of electrolysis, where passing electricity through water (H2O) separates it into hydrogen (H2) and oxygen (O2), producing “green hydrogen” with no carbon emissions in the production process because no fossil fuels are used. The main approaches include alkaline systems using strong alkaline solutions, PEM systems using polymer membranes, and SOEC systems using high-temperature steam. Because it converts surplus solar and wind power into hydrogen for storage and later use as electricity or fuel, it is a natural partner technology for intermittent renewables. Korea is running demonstrations in places such as Jeju and Saemangeum, but still trails Europe and China in equipment scale and cost. Transmission, Distribution & Power Equipment Ultra-high-voltage transformers 9 9 Solid · Gap 0 HD Hyundai Electric, Hyosung Heavy Industries, LS ELECTRIC These are massive power conversion devices that raise the voltage of electricity generated at power plants to hundreds of thousands of volts for long-distance transmission, then lower it again to 220 volts before it enters homes. The operating principle is electromagnetic induction: current flowing through the primary coil creates a magnetic field in the iron core, and changes in that field induce voltage in the secondary coil. By changing the winding ratio of the coils, the voltage can be stepped up or down. Sending power at higher voltage allows the same amount of electricity to flow with less current, reducing transmission losses, which makes transformers an essential choke point in the grid. Korea’s three major players—HD Hyundai Electric, Hyosung Heavy Industries, and LS ELECTRIC—are exporting large volumes to the U.S. with world-class quality. HVDC (high-voltage direct current transmission) 6 8 Catching up · Gap 2 LS Cable & System, HD Hyundai Electric, Hyosung Heavy Industries This is a transmission technology that converts electricity from the usual alternating current (AC) into direct current (DC) and sends it over long distances at ultra-high voltage, including under the sea. AC changes direction dozens of times per second and creates losses around the cable over long distances and in subsea applications, while DC flows in only one direction and suffers less of this loss. The core is the giant converter station that changes AC to DC at the generation side (rectification) and then converts DC back to AC at the destination (inversion). European companies still lead in this converter technology, which is packed with semiconductor power devices. In Korea, LS Cable & System handles the cables, while Hyosung and HD Hyundai handle converter equipment, with domestic HVDC projects such as the East Coast–capital region link serving as the path toward localization. High-voltage circuit breakers (GIS) 8 9 Solid · Gap 1 LS ELECTRIC, HD Hyundai Electric, Hyosung Heavy Industries These are giant safety switches that instantly cut off electricity when faults or overloads occur in the grid, protecting both equipment and people. When the contacts separate during interruption, a powerful arc is created, and that arc must be extinguished quickly, so the inside is filled with special gas with excellent insulating performance. Gas-insulated switchgear (GIS) uses this approach to make equipment far more compact than air-insulated systems, which is especially useful for urban substations. The problem is that the gas commonly used, SF6, is an extremely potent greenhouse gas with more than 20,000 times the warming effect of carbon dioxide, so the industry is now grappling with the shift to cleaner dry air or alternative gases. Korea’s three major players compete globally in this field alongside transformers. Power cables 8 9 Solid · Gap 1 LS Cable & System, Taihan Cable & Solution, Iljin Electric These are the wires that physically carry electricity, made by wrapping a conductor such as copper or aluminum in insulation to prevent leakage and then adding a protective layer. In particular, subsea cables laid on the ocean floor are highly advanced products that must withstand water pressure, corrosion, and fishing vessel anchors while running continuously for tens to hundreds of kilometers. They are used to bring electricity from offshore wind farms to land or to connect islands and continents. Only a handful of companies in the world can make them, which gives suppliers enormous pricing power. Korea’s LS Cable & System is a global subsea cable player expanding factories in the U.S. and Europe, while Taihan Cable & Solution and Iljin Electric are also catching up in the ultra-high-voltage market. ESS & Power Systems ESS (energy storage systems) Short term (~2027) Expansion of extra-high-voltage transformer capacity — HD Hyundai Electric, Hyosung Heavy Industries Commercialization of H-class gas turbines — Doosan Enerbility Expansion of submarine cable plants — LS Cable & System, Taihan Cable & Solution Deployment of fuel cells for power generation — Doosan Fuel Cell Mid term (2028~2030) SMR equipment supply · i-SMR — Doosan Enerbility, KHNP Localization of offshore wind turbines — Doosan Enerbility, CS Wind Internalization of HVDC converter equipment — LS Cable & System, Hyosung Heavy Industries Integration of ESS and smart grids — LG Energy Solution, LS ELECTRIC Long term (2031~2035) Hydrogen-only combustion turbines — Doosan Enerbility Commercialization of water electrolysis for green hydrogen — Doosan Enerbility, Hanwha Solutions Industrialization of nuclear decommissioning — KHNP, KEPCO KPS Superconducting power grid demonstration — LS Cable & System, KEPCO New Power Plant Construction Plan (11th Basic Plan for Electricity Supply and Demand) Based on the 11th Basic Plan for Electricity Supply and Demand finalized in February 2025, this is the roadmap for new construction and conversion through 2038. Category Plan Details Nuclear Saeul Units 3 and 4 and Shin Hanul Units 3 and 4 currently under construction + 2 new large-scale nuclear reactors (2.8GW, targeted for completion in 2037–38) + 1 innovative SMR (i-SMR) Coal → LNG Conversion Convert 28 aging coal-fired power units to LNG by 2036 Carbon-Free Transition Replace 12 coal and LNG units reaching end of life in 2036–38 with carbon-free sources such as pumped storage and hydrogen Renewables Expansion Installed capacity 39GW (2025) → 121.9GW (2038): solar 77.2GW · wind 40.7GW 2038 Generation Mix Target Nuclear 35.2% · Renewables 33.0% · LNG 11.1% · Coal 10.3% Recent Capacity Factors by Power Source Capacity factor indicates how much a generator actually operated relative to its rated output. As a baseload source, nuclear posts the highest level at around 80%, while coal, LNG, which serve peak and mid-load demand, and naturally variable renewables come in lower. (These are rough ranges, as year-to-year and seasonal fluctuations are significant.) Power Source Capacity Factor Key Characteristics Nuclear About 80–83% Baseload — highest utilization rate in Korea Coal About 40–55% Trending lower due to environmental dispatch and demand adjustment LNG Combined Cycle About 40–60% Peak and mid-load; large seasonal and supply-demand swings Solar About 15% Limited by sunlight hours (mainly daytime and clear-weather generation) Onshore Wind About 20–25% Dependent on site conditions and wind resources Offshore Wind Around 30% Higher than onshore, but transmission constraints remain a key variable Regional Power Self-Sufficiency Rates The power self-sufficiency rate (generation ÷ consumption) shows the imbalance in regional electricity supply and demand. North Gyeongsang, South Chungcheong, and Gangwon—where nuclear and thermal power plants are concentrated—exceed 200%, while the Seoul metro area, Daejeon, and Gwangju—where consumption is concentrated—sit around 10%. This gap is the backdrop to the burden on long-distance transmission networks and the debate over regionally differentiated tariffs and distributed energy. (2023, based on the Regional Energy Statistics Yearbook) Region Power Self-Sufficiency Rate Main Generation Sources North Gyeongsang 215.6% Concentrated nuclear fleet (Hanul, Wolsong) South Chungcheong 213.6% Concentrated coal-fired power Gangwon 212.9% Coal, hydro, wind South Jeolla 197.9% Nuclear (Hanbit), thermal, renewables Incheon 186.3% LNG combined cycle, Yeongheung thermal power Busan 174.0% Nuclear (Kori) South Gyeongsang 123.0% Nuclear (Kori), thermal Sejong 99.4% Roughly balanced Ulsan 94.4% Combined cycle, captive generation Jeju 78.2% Renewables, subsea interconnection North Jeolla 71.7% Renewables expanding Gyeonggi 62.5% Highest consumption, insufficient generation Daegu 13.1% Consumption region North Chungcheong 10.8% Consumption region Seoul 10.4% Concentrated consumption, minimal generation Gwangju 9.3% Consumption region Daejeon 3.1% Lowest self-sufficiency rate What matters next is less a nuclear re-rating than the staying power of turbines and maintenance There are two key things to watch going forward. First, how consistently steam turbines, BOP, nuclear plant equipment, and castings/forgings continue to flow through Doosan Enerbility and BHI. Second, how much more the stability of the power maintenance and O&M businesses tied to KEPCO KPS and Doosan Enerbility comes into focus. In Korea’s power plant industry, the core of any investment call is not flashy slogans about new technologies, but how long the already-strong nuclear, turbine, and maintenance pillars can keep compounding recurring revenue and references. The risks are obvious too. If Korea fails to quickly close Gap 3 in offshore wind systems and Gap 2 in H-class gas turbines, hydrogen and ammonia co-firing turbines, SMRs, spent nuclear fuel, and decommissioning, then in the next cycle it will remain an industry that is strong only where it is already strong. That is not necessarily a bad outcome. But control over the value chain will be limited. You probably know this already. In the power plant business, what is truly dangerous is not having no technology at all, but mistakenly believing you do. ※ This article is an analysis compiled from public data and industry materials, and some figures and assessments are estimates.
