Nuclear makes the power, LNG sets the price — the job each source does

In 2025, one in every three units of electricity bought and sold in Korea's power market came from nuclear plants — even though nuclear capacity is only a little over half of LNG capacity. And in 7,295 of that year's 8,760 hours, it was an LNG generator that set the wholesale price.

In 2025, one in every three units of electricity bought and sold in Korea's power market was made by nuclear plants. Yet nuclear capacity is only a little over half of LNG-fired capacity. The plants are smaller, but they made more electricity.Source 1Korea Power Exchange (KPX), *2025 Electricity Market Statistics* (「2025년도 전력시장 통계」, 2026-05), Tables 1-1· 1-2· 1-6· 1-7 (market-participating capacity and traded volume; traded volume provisional)· annual average of the integrated SMP.

Each kind of plant runs for different hours and touches the price of electricity in a different way. Know that difference, and whenever "nuclear" or "LNG" turns up in a story, you also see when in the day that plant runs and how it moves the price of power.

How do the smaller nuclear plants make the most?

At the end of 2025, plants taking part in the power market added up to 146,157 MW. Nuclear was 26,050 MW, or 17.8%; LNG was 48,388 MW, or 33.1%. Of the 547,163 GWh (provisional) traded in the market that year, nuclear made 175,549 GWh, or 32.1%, and LNG made 159,227 GWh, or 29.1%.Source 1Korea Power Exchange (KPX), *2025 Electricity Market Statistics* (「2025년도 전력시장 통계」, 2026-05), Tables 1-1· 1-2· 1-6· 1-7 (market-participating capacity and traded volume; traded volume provisional)· annual average of the integrated SMP. Shares and capacity factors are calculated values.See in sources →

The difference comes from how long each ran. Set running flat out all year as the ceiling, and the share actually made is called the Capacity Factor Capacity factor is the ratio of how much a plant actually generated to the maximum it could have produced. Plants of the same size can deliver very different output depending on their capacity factor. Glossary →. This piece works it out on the basis of electricity traded in the market. Worked out that way, it is about 77% for nuclear, about 45% for coal, about 38% for LNG and about 13% for solar. Worked out on all the electricity the plants actually made, the values could differ. Capacity is "how much can it deliver"; the amount of electricity is "how long did it run." That leaves one question. What decides who runs long and who runs briefly?

Which generator switches on first?

The Korea Power Exchange (KPX), which runs the market and the grid, picks generators so as to meet the next day's demand at the lowest cost. The yardstick is the fuel cost of making one more kWh. The cheapest generators are lined up first and called up in turn until demand is met. This order is called the Dispatch and Merit Order Dispatch is KPX telling generators when and how much to run. In principle it follows the market's priority order: generators with the lowest variable cost run first. Glossary →.

Set the 2025 fuel costs of each source side by side and the order of the line appears. Per kWh, nuclear was KRW 6.39, bituminous coal KRW 73.70, LNG KRW 124.20 and oil-fired plants KRW 319.07.Source 2Korea Power Exchange (KPX), *Fuel Costs* (「연료비용」, Electric Power Statistics Information System (EPSIS, 전력통계정보시스템), accessed 2026-10-23), 2025 annual fuel unit cost (KRW/kWh)generation-cost evaluation data reviewed and resolved by the Cost Evaluation Committee, averaged with weights by plant capacity· note on the screen: 'fuel unit costs are not calculated for non-centrally dispatched plants (new & renewable plants, etc.)' (비중앙급전발전소(신재생에너지발전소 등)는 연료단가를 산정하지 않음). The multiple is a calculated value.See in sources → LNG's fuel cost is about 19 times nuclear's.

Fuel costs are KPX EPSIS 2025 annual averages (see notes). Step widths follow capacity shares; oil is drawn narrow only. The demand line’s position is illustrative: this shows the queue, not actual hourly prices.

Solar and wind don't buy fuel. KPX, too, sets no fuel unit cost for renewable plants.Source 2Korea Power Exchange (KPX), *Fuel Costs* (「연료비용」, Electric Power Statistics Information System (EPSIS, 전력통계정보시스템), accessed 2026-10-23), 2025 annual fuel unit cost (KRW/kWh)generation-cost evaluation data reviewed and resolved by the Cost Evaluation Committee, averaged with weights by plant capacity· note on the screen: 'fuel unit costs are not calculated for non-centrally dispatched plants (new & renewable plants, etc.)' (비중앙급전발전소(신재생에너지발전소 등)는 연료단가를 산정하지 않음). The multiple is a calculated value.See in sources → Which generator switches on first is decided not by the cost of building it, but by the cost of making one more unit.

Why does nuclear run without a break?

Nuclear costs a lot to build, and once built its fuel costs a few won per kWh. Standing at the very front of the line, it is called up even in the small hours, when demand is lowest. Stand a nuclear plant down, and its place has to be filled by generators whose fuel costs ten or twenty times as much. That is why nuclear has the highest capacity factor.

Standing at the front of the line also changes what nuclear is paid. In 2025, the average nuclear was paid for each kWh sold in the market (its settlement unit price) was KRW 79.04.Source 3Korea Power Exchange (KPX), *Settlement Unit Priceby Fuel Source* (「정산단가See in sources → The year's average wholesale price was KRW 112.72.Source 1Korea Power Exchange (KPX), *2025 Electricity Market Statistics* (「2025년도 전력시장 통계」, 2026-05), Tables 1-1· 1-2· 1-6· 1-7 (market-participating capacity and traded volume; traded volume provisional)· annual average of the integrated SMP. Shares and capacity factors are calculated values.See in sources → However, the settlement unit price has several settlement items mixed in besides the wholesale price, so the gap between the two numbers cannot simply be read as what nuclear was paid less. What nuclear is paid also involves a separate adjustment device: the Settlement Adjustment Factor It adjusts the settlements of generators at KEPCO majority-owned companies and of central-dispatch coal units. The rules place it among measures for power price stability. Glossary →, which adjusts the settlement payments of generators owned by generation companies in which KEPCO holds more than half the shares, and nuclear is among them. How much this device accounts for in the gap between the two numbers, this piece could not confirm. Nuclear makes the most power, but it almost never stands in the seat that sets the price.

Why does LNG so often set the price?

The wholesale price for each hour, the SMP (System Marginal Price) SMP is the energy price set for each trading hour in the power market. It is the highest generation price among the generators eligible to set the price in that hour. Glossary → (system marginal price), is set by the cost of the generator that last filled that hour's demand. Generators standing toward the back of the line easily become that "last one."

Of the 8,760 hours in the 2025 mainland power market, LNG generators set the SMP in 7,295 hours, or 83%. Coal (bituminous) set it in 1,412 hours, 16%, and nuclear in 7 hours.Source 4Korea Power Exchange (KPX), *SMP Setting by Fuel Source* (「연료원별 SMP결정」, EPSIS, accessed 2026-10-23), hours in which each fuel source set the mainland system marginal price2025 annual, 8,760 hours, and by month. Shares are calculated values.See in sources → LNG is not the source that made the most electricity, but it is the one that set the price most often.

Who the last one is shifts with each hour's demand and fuel prices. In 2025, coal set the price in 29 of July's 744 hours, and in 283 hours in December.Source 4Korea Power Exchange (KPX), *SMP Setting by Fuel Source* (「연료원별 SMP결정」, EPSIS, accessed 2026-10-23), hours in which each fuel source set the mainland system marginal price2025 annual, 8,760 hours, and by month. Shares are calculated values.See in sources → Even within one year, the owner of the "last seat" changed month by month.

Why is coal shrinking?

Coal stands in the middle of the line. Its fuel is cheaper than LNG, but the government's plans are built around closing old coal plants one after another. The *11th Basic Plan for Electricity Supply and Demand* (「제11차 전력수급기본계획」) says 28 aging coal units will be retired over 2024–2036 and converted to LNG (14.1 GW), and the 12 units of 2037–2038 will be converted mainly to carbon-free sources such as pumped storage, hydrogen-only firing and ammonia co-firing. Coal capacity falls from 39.2 GW at the end of 2023 to 31.7 GW in 2030, 28.1 GW in 2035 and 22.2 GW in 2038.Source 5Ministry of Trade, Industry and Energy, *11th Basic Plan for Electricity Supply and Demand (2024–2038)*, revised notice (「제11차 전력수급기본계획(2024~2038)」 수정공고본, 2025-03-13), printed pp. 43–45confirmed capacity for '23· '30· '35· '38, shares of rated and effective capacity (winter basis) of confirmed plants in '38, peak contribution of new & renewable plants in '38.See in sources →

In the same plan, LNG capacity grows from 43.2 GW in 2023 to 67.0 GW in 2038.Source 5Ministry of Trade, Industry and Energy, *11th Basic Plan for Electricity Supply and Demand (2024–2038)*, revised notice (「제11차 전력수급기본계획(2024~2038)」 수정공고본, 2025-03-13), printed pp. 43–45confirmed capacity for '23· '30· '35· '38, shares of rated and effective capacity (winter basis) of confirmed plants in '38, peak contribution of new & renewable plants in '38.See in sources → It is a picture in which LNG takes over much of the room coal leaves.

Why does solar look small in the table?

In the opening figure, solar was 7.6% of capacity and 2.3% of traded volume. These numbers count only the electricity bought and sold in the power market. Much of Korea's solar never passes through the market; it sells power under power purchase agreements (PPAs) signed directly with KEPCO (Korea Electric Power Corporation), the state-run utility that buys most of the country's power and sells it on to consumers.

KPX's statistics screen lists this out-of-market capacity separately. In December 2025, solar inside the market was 11,040 MW, and capacity under KEPCO PPAs was 20,807 MW. Outside the market is nearly twice inside. The electricity traded under PPAs that year was 25,338 GWh, about twice the solar power traded in the market.Source 7Korea Power Exchange (KPX), *Market-Participating Capacityby Fuel Source* (「시장참여설비용량See in sources →

Widen the view to all the electricity made by generating businesses and the picture shifts again. By KEPCO's statistics, of the 595,649 GWh generated in 2025 (including KEPCO purchases), the new & renewable line was 62,214 GWh, about 10%.Source 8Korea Power Exchange (KPX), *Generationby Energy Source* (「발전량See in sources → Even this leaves out the self-use solar on the roofs of homes and factories. One big reason solar looks small is that the table counts only what is inside the market.

What to watch when using the numbers

If you handle numbers by source in a report or story, four points are worth noting.

  • Traded volume is not generation. It is the amount bought and sold in the market, so KEPCO PPAs and self-use power are left out. When you talk about the "renewable share," first say which table and which denominator.
  • Even for the same year and the same plants, the values differ slightly from table to table. Annual statistics are final published figures; the monthly values on the statistics screen are operating data and can change later. Within one sentence, divide only numbers from the same table.
  • Fuel cost, settlement unit price and SMP are different values. Fuel cost is an average weighted by plant capacity, so it differs from the cost of the last generator in a given hour. The settlement unit price is not a fuel cost but the average money a source was paid in the market. Put all three on one line and compare their sizes, and you can easily reach a wrong conclusion.
  • Planned values are not results. The yearly capacities in the Basic Plan for Electricity Supply and Demand are a target path. Whether plants actually closed has to be checked separately in plant-by-plant retirement records.

Who stands where in 2038?

The capacity the 11th plan draws for the end of 2038 (on the basis of plants already confirmed) is nuclear 31.7 GW, coal 22.2 GW, LNG 67.0 GW and renewables 121.9 GW. By capacity alone, renewables are 47.3%, close to half.Source 5Ministry of Trade, Industry and Energy, *11th Basic Plan for Electricity Supply and Demand (2024–2038)*, revised notice (「제11차 전력수급기본계획(2024~2038)」 수정공고본, 2025-03-13), printed pp. 43–45confirmed capacity for '23· '30· '35· '38, shares of rated and effective capacity (winter basis) of confirmed plants in '38, peak contribution of new & renewable plants in '38.See in sources →

11th Basic Plan for Electricity (2024–2038), revised notice pp. 43–45 (see notes). From 2030 the values are planned and framed with a dashed line. Effective share counts only what can be relied on at the winter peak.

But in the same table, switch to the share that can be counted on at the moment electricity is needed most (effective capacity), and on a winter basis renewables are 9.1% while LNG is 45.3%. Of 77,203 MW of solar, the plan counts only 14.3% toward that moment.Source 5Ministry of Trade, Industry and Energy, *11th Basic Plan for Electricity Supply and Demand (2024–2038)*, revised notice (「제11차 전력수급기본계획(2024~2038)」 수정공고본, 2025-03-13), printed pp. 43–45confirmed capacity for '23· '30· '35· '38, shares of rated and effective capacity (winter basis) of confirmed plants in '38, peak contribution of new & renewable plants in '38.See in sources → Having a lot of plant is not the same as having it there when it's needed.

Midday with the sun up and evening after sunset; the small hours when demand bottoms out and 7 p.m. when people get home and switch on the lights. Over one day, the same generators stand in different places in the line, and each time the last one changes. The reason the price of electricity differs by the hour lies in the shape of that day.
