South Korean nuclear restarts to help meet peak demand

Returning nuclear capacity in South Korea is expected to help the country cope with a spike in seasonal temperatures and peak power demand.

Three nuclear units are expected to resume operations in the near term, according to a notice published by energy and trade ministry Motie today.

These are the 1.4GW Shin Kori 4 reactor, which has been off line because of an unplanned outage since 29 May, and the 700MW Wolsong 3 and 1GW Shin Wolsong 1 units.

Shin Wolsong 1 was expected to return from maintenance on 27 July, but instead started up yesterday and will reach full capacity by 21 July, the government said. Wolsong 3 is due to return on 23 July, as scheduled.

The Shin Kori 4 reactor is awaiting approval to restart following its outage and the completion of an inspection on 15 July and could resume operations on 21 July, the ministry said.

If these units return as planned, nuclear availability would average 16.6GW this week, from 15.5GW last week. Average July availability would be 16.2GW, down from actual generation of 18.4GW in July 2020.

The boost to nuclear availability should help to balance peak demand, but is unlikely to drastically slow the expected rise in generation from fossil fuel compared with a year earlier as power demand surges.

Daily peak power demand has averaged 77.9GW so far this month, up from 67.6GW a year earlier. Daily mean Seoul temperatures are forecast to average 28.2°C this month, which would be only the second time in 10 years that July temperatures have surpassed 28°C and higher than the 26.3°C 10-year average for the month.

Argus analysis shows that combined coal and gas-fired generation may need to rise by 6.4GW on the year to 45.6GW this month.

Cop: Drafts point to trade-off on finance, fossil fuels

Baku, 22 November (Argus) — The new draft on the climate finance goal from the UN Cop 29 climate summit presidency has developed nations contributing $250bn/yr by 2035, while language on fossil fuels has been dropped, indicating work towards a compromise on these two central issues. There is no mention of fossil fuels in either the new draft text on the global stocktake — which follows up the outcome of Cop 28 last year, including "transitioning away" from fossil fuels — or in the new draft for the climate finance goal. Developed countries wanted a reference to moving away from fossil fuels included, indicating that not having one would be a red line. The new draft text on the climate finance goal would mark a substantial compromise for developing countries, with non-profit WRI noting that this is "the bridging text". Parties are negotiating the next iteration of the $100bn/yr that developed countries agreed to deliver to developing nations over 2020-25 — known as the new collective quantified goal (NCQG). The new draft sets out a figure of $250bn/yr by 2035, "from a wide variety of sources, public and private, bilateral and multilateral, including alternative sources". It also notes that developed countries will "take the lead". It sets out that the finance could come from multilateral development banks (MDBs) too. "It has been a significant lift over the past decade to meet the prior, smaller goal... $250bn will require even more ambition and extraordinary reach," a US official said. "This goal will need to be supported by ambitious bilateral action, MDB contributions and efforts to better mobilise private finance, among other critical factors," the official added. India had indicated earlier this week that the country was seeking around $600bn/yr for a public finance layer from developed countries. Developing countries had been asking for $1.3 trillion/yr in climate finance from developed countries, a sum which the new text instead calls for "all actors" to work toward. The draft text acknowledges the need to "enable the scaling up of financing… from all public and private sources" to that figure. On the contributor base — which developed countries have long pushed to expand — the text indicates that climate finance contributions from developing countries could supplement the finance goal. It is unclear how this language will land with developing nations. China yesterday reiterated that "the voluntary support" of the global south is not part of the goal. The global stocktake draft largely focuses on the initiatives set out by the Cop 29 presidency, on enhancing power grids and energy storage, though it does stress the "urgent need for accelerated implementation of domestic mitigation measures". It dropped a previous option, opposed by Saudi Arabia, that mentioned actions aimed at "transitioning away from fossil fuels". Mitigation, or cutting emissions, and climate finance have been the overriding issues at Cop 29. Developing countries have long said they cannot decarbonise or implement an energy transition without adequate finance. Developed countries are calling for substantially stronger global action on emissions reduction.

Japan’s Taketoyo to resume biomass co-firing in 2027

Japan’s Taketoyo to resume biomass co-firing in 2027

Tokyo, 22 November (Argus) — Japan's largest electricity producer Jera aims to resume coal and biomass co-firing at the 1.1GW Taketoyo plant in 2027's first quarter, after a fire halted plant operations in January. Jera announced on 22 November that the thermal power plant in central Japan's Aichi prefecture would resume co-firing wood pellets with coal at a rate of 8pc, around the end of the 2026-27 fiscal year ending in March. This will come after its safety measures are completed. The plant's co-firing rate was 17pc before the serious fire, which was caused by an explosion of dust from wood pellets. The company will consider increasing the co-firing rate again in the future, provided safety can be ensured. But the plant will restart coal-only combustion in early January 2025, operating mainly during the summer and winter seasons, when electricity demand is high. Jera will keep operation rates low at Taketoyo and other coal-fired plants when electricity demand is low and rely more on gas-fired generation, to achieve its initial plan to cut CO2 emissions through co-firing at Taketoyo. Taketoyo started co-firing operations in August 2022 and burned around 500,000 t/yr of wood pellets imported from the US and Vietnam. It will burn 200,000 t/yr after it resumes co-firing at 8pc. The plant will slow down the speed of wood pellet conveyors to reduce friction as a part of safety measures, which means it must also reduce its coal and biomass co-firing rate. It is also currently working on other safety measures, such as installing air pressure conveying facilities dedicated to wood pellets and explosion suppressor systems to inject fire extinguishing agents. The outage at Taketoyo has encouraged Jera to boost replacement gas-fired generation, with the extra gas-fired costs accounting for most of the estimated cost resulting from the shutdown, which could be tens of billion yen in the 2024-25 fiscal year ending in March.

Cost of government support for fossil fuels still high

Cost of government support for fossil fuels still high

London, 21 November (Argus) — The cost of government measures to support the consumption and production of fossil fuels dropped by almost a third last year as energy prices declined from record highs in 2022, according to a new report published today by the OECD. But the level of fiscal support remained higher than the historical average despite government pledges to reduce carbon emissions. In an analysis of 82 economies, data from the OECD and the IEA found that government support for fossil fuels fell to an estimated $1.1 trillion in 2023 from $1.6 trillion a year earlier. Although energy prices were lower last year than in 2022, countries maintained various fiscal measures to both stimulate fossil fuel production and reduce the burden of high energy costs for consumers, the OECD said. The measures are in the form of direct payments by governments to individual recipients, tax concessions and price support. The latter includes "direct price regulation, pricing formulas, border controls or taxes, and domestic purchase or supply mandates", the OECD said. These government interventions come at a large financial cost and increase carbon emissions, undermining the net-zero transition, the report said. Of the estimated $1.1 trillion of support, direct transfers and tax concessions accounted for $514.1bn, up from $503.7bn in 2022. Transfers amounted to $269.8bn, making them more costly than tax concessions of $244.3bn. Some 90pc of the transfers were to support consumption by households and companies, the rest was to support producers. The residential sector benefited from a 22pc increase from a year earlier, and support to manufacturers and industry increased by 14pc. But the majority of fuel consumption measures are untargeted, and support largely does not land where it is needed, the OECD said. The "under-pricing" of fossil fuels amounted to $616.4bn last year, around half of the 2022 level, the report said. "Benchmark prices (based on energy supply costs) eased, particularly for natural gas, thereby decreasing the difference between the subsidised end-user prices and the benchmark prices," it said. In terms of individual fossil fuels, the fiscal cost of support for coal fell the most, to $27.7bn in 2023 from $43.5bn a year earlier. The cost of support for natural gas has grown steadily in recent years, amounting to $343bn last year compared with $144bn in 2018. The upward trend is explained by its characterisation as a transition fuel and the disruption of Russian pipeline supplies to Europe, the report said.

Cop: Talks in Baku torn between mitigation and finance

Cop: Talks in Baku torn between mitigation and finance

Edinburgh, 21 November (Argus) — Developing and developed nations remain at loggerheads on what progress on climate finance and mitigation — actions to cut greenhouse gas emissions — should look like at the UN Cop 29 climate summit. But Cop 30 host Brazil has reminded parties that they need to stick to the brief, which is finance for developing countries. Concluding a plenary where parties, developed and developing, listed grievances, environment minister Marina Silva recognised "the excellent progress achieved" on mitigation at Cop 28. She listed paragraphs of the Cop 28 deal, including the energy package and its historic call to transition away from fossil fuels in energy systems. "We are on the right track," she said, talking about mitigation, but "our greatest obligation at this moment is to make progress with regard to financing". "This is the core of financing that will pave our collective path in ambition and implementation at Cop 30," Silva said, adding that $1.3 trillion for developing countries should be "the guiding star of this Cop". Parties are negotiating a new collective quantified goal (NCQG) — a new climate finance target — building on the $100bn/yr that developed countries agreed to deliver to developing countries over 2020-25. But developed countries insist that a precise number for a goal can only be produced if there is progress on mitigation and financing structure for the NCQG. "Otherwise you have a shopping basket but you don't know what's in there," EU energy commissioner Wopke Hoekstra said. Some developing nations said they need the "headline number first". Some developing countries, including Latin American and African nations as well as island states, have also complained about the lack of mitigation ambition. Cop is facing one of the "weakest mitigation texts we have ever seen," Panama said. But they also indicated that financial support was missing to implement action. Developed countries at Cop 29 seek the implementation of the energy pledges made last year. "What we had on our agenda was not just to restate the [Cop 28] consensus but actually to enhance and to operationalise that," but the text goes in the opposite direction, Hoekstra said, talking about the latest draft on finance. Whether hints that Brazil has mitigation in focus for next year's summit will be enough to assuage concerns from developed countries at Cop 29 on fossil fuel ambitions remains to be seen. The communique of the G20, which the country hosted, does not explicitly mention the goal to transition away from fossil fuels either. The developed countries' mitigation stance grew firmer after talks on a work programme dedicated to mitigation, the obvious channel for fossil fuel language, was rescued from the brink of collapse last week. Discussions have stalled, but another text — the UAE dialogue which is meant to track progress on the outcomes of Cop 28 — still has options referring to fossil fuels. But in these negotiations too, divisions remain. "The UAE dialogue contains some positive optional language on deep, rapid and sustained emissions reductions and the [Cop 28] energy package, climate think-tank E3G said. But Saudi Arabia has made clear that this was unacceptable, while India, which worked to water down a coal deal at Cop 26, is pushing back on the 1.5°C temperature limit of the Paris Agreement. Negotiators are starting to run out of time. Draft after draft, the divide fails to be breached with no agreement on an amount for the finance deal. "We cannot talk about a lower or higher number because there is no number," noted Colombia's environment minister Susana Muhamad. The next iteration should have numbers based on the Cop 29 presidency's "view of possible landing zones". The fact that the draft text on finance has no bridging proposal is a concern, non-profit WRI director of international climate action David Waskow said. Finance was always meant to be the centrepiece of Cop 29. Parties have not formally discussed the goal in 15 years, and have been trying to prepare for a new deal through technical meetings for the past two years. But the discussion needs to end in Baku.

Cop: EU, four countries commit to 1.5°C climate plans

Baku, 21 November (Argus) — The EU, Canada, Mexico, Norway and Switzerland have committed to submit new national climate plans setting out "steep emission cuts", that are consistent with the global 1.5°C temperature increase limit sought by the Paris Agreement. The EU and four countries made the pledge at the UN Cop 29 climate summit in Baku, Azerbaijan today, and called on other nations to follow suit — particularly major economies. Countries are due to submit new climate plans — known as nationally determined contributions (NDCs) — covering 2035 goals to the UN climate body the UNFCCC by early next year. The EU, Canada, Mexico, Norway and Switzerland have not yet submitted their plans, but they will be aligned with a 1.5°C pathway, EU climate commissioner Wopke Hoekstra said today. The Paris climate agreement seeks to limit the global rise in temperature to "well below" 2°C and preferably to 1.5°C. Canada's NDC is being considered by the country's cabinet and will be submitted by the 10 February deadline, Canadian ambassador for climate change Catherine Stewart said today. Switzerland's new NDC will also be submitted by the deadline, the country's representative confirmed. Pamana's special representative for climate change Juan Carlos Monterrey Gomez also joined the press conference today. Panama, which is designated as carbon negative, submitted an updated NDC in June. It is planning to submit a nature pledge, Monterrey Gomez said. "It is time to streamline processes to get to real action", he added. The UK also backed the pledge. The UK announced an ambitious emissions reduction target last week. The UAE — which hosted Cop 28 last year — released a new NDC just ahead of Cop 29, while Brazil, host of next year's Cop 30, released its new NDC on 13 November during the summit. Thailand yesterday at Cop 29 communicated a new emissions reduction target . Indonesia last week said that it intends to submit its updated NDC ahead of the February deadline, with a plan placing a ceiling on emissions and covering all greenhouse gases as well as including the oil and gas sector. Colombia also indicated that its new climate plan will seek to address fossil fuels, but it will submit its NDC by June next year .
