S Korea to convert half of existing coal fleet to gas

The closure or conversion of ageing South Korean coal-fired power plants could cut power sector consumption by 19mn-28mn t/yr by 2034, although the decline may be slowed in the near term by the start-up of new plants in the next five years.

South Korea plans to shut a total of 15.3GW of coal-fired capacity by 2034, according to a draft of the country's ninth basic electricity plan released on 7 May, of which 12.7GW will be switched to run on LNG. South Korean state-owned Kepco utilities currently operate 33.7GW of coal capacity across 56 units.

Some 30 of those coal units that reach 30 years of service by 2034 will be retired, 24 of which will be converted to run on natural gas, according to the draft. The exact units to be converted were not specified, but are likely to comprise power plants earmarked for conversion by the five individual state-owned utilities.

The existing eighth electricity plan already includes the conversion of the 500MW Dangjin 1 and 2 units to run on gas in 2029, with the 560MW Samcheonpo 3 and 4 units to be retired in March 2023 and the 500MW Taean 1 and 2 units scheduled to close in 2025.

In addition, Korea East-West Power has proposed the conversion of its 500MW Dangjin 3 and 4 in 2030, according to board meeting notes published on its website.

Fellow state-owned utility Korea South East Power (Koen) has proposed converting its 500MW Samcheonpo units 5 and 6 in July 2027 and January 2028, respectively, and its 800MW Youngheung units 1 and 2 in June 2034 and December 2034. Koen's 560MW Samcheonpo units 1 and 2 are already scheduled to retire as part of the eighth plan.

Korea Southern Power (Kospo) plans to convert a total of 3GW of ageing coal capacity across six units in 2026-31. Kospo's meeting notes do not specify the exact units to be converted, but the 500MW Hadong units 1-6 are the oldest in its fleet. Kospo is already scheduled to retire its 250MW Honam units 1 and 2 in January 2021.

Korea Western Power's (Kowepo) 500MW Taean units 3 and 4 have been proposed for conversion to LNG in December 2032 and Korea Midland Power's (Komipo) 500MW Boryeong units 5 and 6 in December 2024 and December 2025, respectively. The 500MW Boryeong units 1 and 2 are scheduled to close in December this year as part of the eighth plan, but Komipo has decided to convert the units to run on LNG in December 2026, according to board meeting minutes.

But despite the swathe of plant retirements and fuel conversions, seven new coal units are currently under construction with a combined capacity of 7.26GW. This means that South Korea's installed coal capacity will likely peak around 2024-25, potentially slowing the decline in coal burn until later this decade.

State-owned utilities consumed 83.3mn t of coal (with an unspecified calorific value) to generate 226.8TWh in 2019, according to Kepco data. This represented a 71pc utilisation rate of the country's state-owned fleet, down from 75pc in 2018. Coal-fired load factors may remain under pressure in the coming years, as the government has pledged to restrict the use of coal plants to improve air quality during the peak winter heating season each year. Increasingly competitive gas prices and rising nuclear and renewable capacity may also stem the use of coal plants.

If the use of South Korea's installed state-owned coal capacity ranges between 60pc and 70pc, annual coal consumption for power could drop to as low as 53mn-62mn t/yr in 2034, according to Argus analysis. But annual power sector demand is set to average around 80mn t/yr in the next five years, assuming a 70pc average load each year, as new capacity additions will outpace retirements in the near term. But the record 89.3mn t of consumption recorded in 2018 may be unlikely to be repeated.

Ninth plan targets renewables growth

The government — recently strengthened by the success of President Moon Jae-in's party in last month's national assembly elections — is targeting a 62.3GW increase in renewable capacity by 2034, in line with a previous target set out in the third energy plan.

This would bring total renewable capacity to around 79GW, which the government expects to represent around 40pc of the country's installed capacity, compared with 15pc now. The ninth plan sees coal, nuclear and gas-fired capacity accounting for 14.9pc, 9.9pc and 31pc, respectively, by 2034.

The increase in renewable generation would offset declines in coal, gas and nuclear generation and cater for growth in overall power demand. The eighth plan targeted a 24 percentage point increase in renewables' share of power generation to 33.7pc by 2030, with coal, gas and nuclear shares falling by around nine, five and seven percentage points. The targets in the ninth plan — to be confirmed in the second half of the year — may now be even tougher on coal.

Baltic April gas consumption rises on year

Baltic April gas consumption rises on year

London, 8 May (Argus) — Gas demand in the three Baltic states and Finland was up by 26pc on the year in April, although there were diverging trends in the different markets. Consumption in Finland, Estonia, Latvia and Lithuania totalled 3.56TWh, up from 2.82TWh a year earlier but down from 4.31TWh in March ( see data and download, graph ). That said, total demand was still well below the 2018-21 average for the month of 5.03TWh. Consumption was up on the year in all three Baltic countries, but Finnish demand edged down. This was the first month in which Finnish demand was lower on the year since April 2023. In contrast, Lithuanian consumption surged by nearly 50pc on the year, and was also higher than in February and March despite the end of the traditional heating season. Gas-fired power generation held broadly stable from a year earlier, totalling 305MW across the four countries compared with 301MW in April last year ( see gas-fired output table ). Output edged down in Estonia and Lithuania and dropped by 25MW in Finland, but this was offset by a 31MW increase on the year in Latvia. But, unlike in March, gas-fired output fell by 246MW, a large contributing factor to the lower gas demand on the month. Many combined heat and power plants will have switched off at around the end of March or mid-April as the traditional heating season came to a close, possibly driving the fall in gas-fired output. But renewables generation was also stronger in April than March, particularly in Finland, where wind output rose to 2.03GW from 1.63GW, while hydro also stepped up. In Lithuania, solar and waste-based production increased on the month. Demand was also stronger despite higher year-on-year minimum temperatures in all four capital cities, which may have curbed most residual heating demand after the end of the traditional heating season, although there was a brief cold snap towards the middle of the month that temporarily drove up demand ( see temperatures table ). With gas-fired power generation only marginally higher than a year earlier, and the warmer weather curbing residential demand, a possible uptick in industrial demand may have driven the aggregate rise in consumption. Average prices on the regional GET Baltic exchange were €33.30/MWh in April, up by 8pc on the month but 30pc lower than a year earlier, the exchange said. Prices increased in around the middle of April "due to the unexpectedly cold weather and the increased demand for gas in the market", but then fell again "as the weather warmed", GET Baltic chief executive Giedre Kurme said. There were a total of 2,400 transactions last month for a combined 642GWh of gas. Volumes sold on the Finnish market accounted for 42pc, the joint Latvian-Estonian market 33pc, and the remaining 25pc was sold in Lithuania. Klaipeda and Balticconnector to change flows The return of the Finnish-Estonian Balticconnector pipeline and the start of maintenance at the Klaipeda LNG terminal in Lithuania will drive changed flow patterns this month. The Balticconector resumed commercial operations on 22 April after being off line since 8 October following a rupture caused by a dragging ship anchor . The reconnection of Finland to its southern neighbours has allowed for strong southward flows since 22 April, at an average of 62 GWh/d on 22 April-7 May. Some of this gas is probably being injected into storage, with the region's only facility at Incukalns switching to net injections on 23 April from net withdrawals of 7 GWh/d earlier in the month. Net injections have since averaged 46 GWh/d on 23 April-6 May, the latest data from EU transparency body GIE show. Stocks at Incukalns ended the withdrawal season on 30 April at 11.29TWh, the highest since at least 2014 and well above the previous high from last year of 9.03TWh. Large volumes of gas that had been stored over the previous summer for export to Finland over the winter were left stranded in Incukalns after the Balticconnector went off line. And the Klaipeda LNG terminal began maintenance on 1 May, which will last until 15 June, as the terminal's Independence floating storage and regasification unit (FSRU) departed for dry-docking in Denmark. As a result, there were net exports from Poland to Lithuania for the first time since early November, at an average of 17 GWh/d on 1-7 May. Some of this gas could have been withdrawn from Ukrainian storage, with flows from Ukraine to Poland averaging 10 GWh/d over the same period. Lithuania's largest supplier Ignitis has said it stored some volumes in Ukraine. And flows at the Kiemenai border point with Latvia have also flipped towards Lithuania, averaging 11 GWh/d on 1-7 May, compared with net flows towards Latvia of 15 GWh/d in April. That said, there were no flows at the point on 6-26 April.

New Zealand’s Genesis Energy to resume coal imports

New Zealand’s Genesis Energy to resume coal imports

Sydney, 8 May (Argus) — New Zealand's upstream firm and utility Genesis Energy plans to resume thermal coal imports later this year to feed its dual gas- and coal-fired Huntly power plant. The resumption was because of lower domestic gas production and rapidly declining coal stockpiles, and will mark the firm's first coal imports since 2022. Coal inventories at the 953MW Huntly plant, — New Zealand's largest power station by capacity and the country's only coal-fired facility — recently slipped below 500,000t, down from 624,000t at the end of March, and will fall below 350,000t by the end of the winter. This will trigger a need to purchase more coal to maintain a target operational stockpile of around 350,000t ahead of winters in 2025 and 2026, the company said on 8 May. Imports are currently the most efficient option for the quantity the company will need, with a delivery time of around three months, chief executive Malcolm Johns said. Genesis typically imports from Indonesia, the company told Argus . Gas production in New Zealand has dropped at a faster rate than expected, with major field production in April down by 33pc on the year, Genesis said. Lower gas availability typically leads to more coal burn, because the Huntly plant runs on gas and coal. This is in addition to an extended period of low hydropower inflows in recent months, which required higher thermal generation to ensure supply security. A prolonged outage at Huntly's unit 5 gas turbine between June 2023 and January 2024 also led to an even greater need for coal-fired generation, Genesis said. Biomass transition The company — which is 51pc owned by the state — is the second-largest power retailer in New Zealand, behind domestic utility Mercury, according to data from the Electricity Authority. It has a NZ$1.1bn ($659mn) programme for renewable power generation and grid-scale battery storage , which includes a potential replacement of coal with biomass at Huntly. But the transition to biomass "will take some years," Johns said. Genesis has successfully completed a biomass burn trial at Huntly last year and has collaboration agreements with potential New Zealand pellet suppliers, but there is currently no local source for the type of pellets needed for the plant. Genesis is hoping to move to formal agreements "as soon as counterparties are able". The company will not consider importing pellets, it told Argus . "We will only use biomass if we can secure a local New Zealand supply chain that is sustainable and cost-effective," it said. Domestic gas production New Zealand's three-party coalition government said separately on 8 May that the "material decline" in local gas production threatens energy security, blaming the previous Labour party-led government for "policy decisions which have disincentivised investment in gas production." The decisions — which were part of the former government's pledge to achieve a carbon-neutral economy by 2050 — led to a reduction in exploration for new gas resources since 2021, while suppressed maintenance drilling reduced production from existing gas fields, according to a joint release from energy minister Simeon Brown and resources minister Shane Jones. "Due to this significant reduction in gas production, the government has also been advised that some large gas consumers are expressing concern about their ability to secure gas contracts," the government said. Major industrial users such as Canada-based methanol producer Methanex have been forced to reduce production as a result, it noted. "We are working with the sector to increase production, and I will be introducing changes to the Crown Minerals Act to parliament this year that will revitalise the sector and increase production," Jones added.

Brazil state faces power outages after record flood

Sao Paulo, 6 May (Argus) — Brazil's Rio Grande do Sul state is facing power outages following record floods that killed more than 80 people and forced over 130,000 people out of their homes. The extreme weather took three substations, 25 transmission lines, five hydroelectric plants and 11 power transformers off line, according to grid operator ONS. In response, ONS started importing power from neighboring Uruguay and requested that the 250MW hybrid natural gas and diesel Canoas and 345MW coal-fired Pampa Sul power plants increase power generation. Earlier today, an estimated 435,000 consumers did not have electricity. The rains affected 341 of the 497 cities in the state, where the government declared a state of emergency in 336 municipalities. The government is working to re-establish power to the state as quickly as possible, the mines and energy ministry said in a social media post. The ministry also held an emergency meeting early yesterday and today to guarantee fuel supplies in the state . State capital Porto Alegre is expected to receive more rain later this week, according to Rio Grande do Sul-based weather forecaster MetSul. Metsul warned that parts of the Porto Alegre metropolitan area could remain uninhabitable for weeks or months. Brazil's airline association Abear said that the Salgado Filho international airport will remain closed indefinitely, after the airport's runway flooded.

Indonesia’s MBAP sets lower coal output target for 2024

Manila, 6 May (Argus) — Indonesian coal producer Mitrabara Adiperdana (MBAP) has set a lower output target of 2.01mn t for 2024, to focus on developing its mining infrastructure. MBAP plans to improve its mining infrastructure to prepare for higher output in the next two years. It has earmarked $57.8mn for its capital expenditure this year, 49pc of which will be used for infrastructure development. This investment will allow MBAP to increase its output to 2.45mn t/yr in 2025-26, in line with its approved RKAB work plans. The firm aims to produce 2.01mn t in 2024, down by nearly 4pc from its 2023 output. The Indonesian Ministry of Energy and Mineral Resources (ESDM) has approved MBAP's target. But MBAP hopes to sell 2.3mn t of coal in 2024, up from 2.13mn t a year earlier, with sales including deliveries by its coal trading arm. Exports accounted for 73pc of the firm's total sales in 2023 and is expected to remain steady at 72-75pc this year. South Korea is expected to remain MBAP's largest market, with the country accounting for 29pc of total sales in 2023. But sales to China, which were at 18pc last year, are expected to increase this year. By Antonio delos Reyes Send comments and request more information at feedback@argusmedia.com Copyright © 2024.

India’s Adani Power raises imported coal use in Jan-Mar

Singapore, 6 May (Argus) — India's leading private sector utility Adani Power more than doubled its use of imported thermal coal during January-March and in the April 2023-March 2024 fiscal year to meet rising power demand. The Bombay Stock Exchange-listed firm used 5.19mn t of imported coal over January-March, more than twice that of 1.99mn t a year earlier. Domestic coal burn also rose by nearly 18pc on the year to 8.83mn t during January-March, following higher availability of local fuel and increased dispatches to utilities. Adani Power consumed 19.44mn t of imported coal over India's April 2023-March 2024 fiscal year. This was also more than double that of 7.66mn t in 2022-23. Its domestic coal burn increased by 10pc on the year to 31.72mn t in 2023-24. Higher imports came on the back of a sharp drop in seaborne prices. The Argus -assessed Indonesian GAR 4,200 kcal/kg coal averaged $57.88/t fob Kalimantan over April 2023-March 2024, down by over 31pc from an average of $84.45/t in the year earlier. The company's fuel cost stood at 3.33 rupees/kWh sold (0.04¢/kWh sold) in January-March, down from Rs5.30/kWh sold a year earlier because of lower blended fuel costs, following a decline in seaborne coal prices. Fuel cost for 2023-24 stood at Rs3.59/kWh compared with Rs4.78/kWh in the previous year. Lower imported coal prices also boosted power offtake under imported coal-based power purchase agreements. The company sold 22.13bn units of electricity in January-March, up significantly from 14.25bn units sold a year earlier. It sold 79.27bn units in 2023-24, up from 53.39bn units in the year earlier. Higher volumes during January-March and the fiscal year were driven by its Mundra, Udupi, Raipur, and Mahan plants — apart from the incremental contribution of the Godda unit — which were commissioned in April 2023. Domestic power sales volumes were driven by growing power demand across the country, the company said. Utility demand could continue to support imports by utilities and lift overall Indian demand for seaborne coal. India imported 14.27mn t of thermal coal in March, up by 8pc from 13.2mn t a year earlier, according to shipping broker Interocean data. Thermal power expansion plans Adani Power operates 15.25GW of thermal generation capacity in the Gujarat and Maharashtra states of west India, Madhya Pradesh and Chhattisgarh in central India, Rajasthan in north India, Karnataka in south India and Jharkhand in eastern India. The firm is eyeing a capacity of more than 24GW by 2029. It is undertaking a brownfield thermal capacity expansion of 1.6GW at its 1.2GW Mahan power project in Madhya Pradesh. It has started developing a 1.6GW expansion at its existing 600MW unit in Chhattisgarh. Adani Power has also emerged as the frontrunner to acquire thermal generation capacity and an under-construction project from domestic debt-ridden Lanco Amarkantak Power. Lanco owned and operated a 600MW thermal power plant in central India's Chhattisgarh state and was planning 1.32GW of generating capacity under the second phase of the project. Adani is in the process of acquiring a 1.2GW debt-ridden thermal power project in south India's Tamil Nadu state. Plant operator Coastal Energen is also having a corporate resolution insolvency process. It is evaluating an organic expansion of 1.6GW, besides considering other inorganic acquisition opportunities, to meet strong demand for thermal power in the coming years, the company said.
