Japan’s Higashidori No.1 reactor faces further delays
Japanese utility Tohoku Electric Power has confirmed a further delay in reinforcement works at its 1,100MW Higashidori No.1 nuclear reactor, with its completion date unknown.
The postponement in restarting the Higashidori reactor in northern Aomori prefecture would encourage Tohoku to secure replacement thermal fuels — such as LNG and coal — for an extended period, although the company is planning to resume another reactor in September.
Tohoku previously aimed to complete the reinforcement work at Higashidori in the April 2024-March 2025 fiscal year. But the company needs more time to clear all the procedures for the assessment of basic earthquake ground motions and tsunamis, and to prepare for the plant inspection. It is still unclear when the company will complete the safety measures.
The Higashidori reactor is undergoing inspections by Japan's nuclear regulation authority (NRA), based on stricter safety rules following the 2011 Fukushima nuclear disaster. The reactor will need to pass the safety checks and secure approval from local governments before restarting.
Tohoku has three commercial reactors, including two at Onagawa in Miyagi prefecture and the Higashidori No.1 reactor, of which it applied to restart two. The 825MW Onagawa No.2 reactor has already cleared the NRA's safety inspections and obtained permission from local authorities to restart. The company is now planning to restart the Onagawa No.2 reactor in September.
The possible return of the Onagawa No.2 reactor will help Tohoku reduce consumption of thermal fuels. The company used 2.76mn t of LNG in April-December 2023, up by 12pc from a year earlier, in the absence of all its nuclear reactors. But its coal consumption fell by 12pc to 5.68mn t during the period.

Floods stress Brazil energy sector vulnerability
Floods stress Brazil energy sector vulnerability
New York, 10 May (Argus) — Record flooding in Brazil's Rio Grande do Sul state over the past week underscores vulnerabilities in the country's energy system to extreme weather, which could also slow its pace of transition to cleaner energies. Nearly one week after record rainfall began flooding the state, power outages continue to plague it, with nearly 400,000 residents still in the dark. The flooding forced companies to suspend operations of critical infrastructure for the power sector, including three substations, 25 transmission lines, six hydroelectric plants and 11 power transformers. This led grid operator ONS to import power from Uruguay to meet domestic demand. With forecasts pointing to more rain, it is increasingly clear that it will take weeks if not months for the state to start returning to normal. The Rio Grande do Sul government estimates that the floods will cost the stateR19bn ($3.6bn?) . The tragedy in southern Brazil comes less than a year after a record drought struck the Amazon basin, which pushed water levels of the Amazon River and its tributaries to their lowest in 120 years. The drought reduced hydroelectric output from the region's plants and interrupted transport of fuel along key river corridors, leaving many households without power, because of the lack of diesel to operate generators used in off-grid communities. These crises highlight the country's failure to prepare for extreme weather and underscore the lack of investment in critical infrastructure, including in the energy sector. A study by the World Bank from 2023 warned of the need to upgrade the country's aging infrastructure and of future power supply risks. Brazil's large hydroelectric plants have been operating for an average of 55 years, according to the study, and need investments to boost efficiency and to limit the impact of extreme weather. A total of 11 hydroelectric plants in Rio Grande do Sul are being monitored, including six that present an elevated risk of rupture, such as the 28MW 14 de Julho plant that experienced a partial rupture last week because of the heavy rains. Authorities will now need to change their focus, which has been largely on limiting the impact of dry weather on the electricity sector, especially following the 2021 droughts, that resulted in expansion of thermoelectric generation. More recently, electricity regulator Aneel has been focusing on making power distribution and transmission networks more resilient to extreme weather, especially after downed power lines resulted in extended blackouts for some 4mn consumers in the city of Sao Paulo and over 1.3mn consumers in Rio de Janeiro. The sector is working to make transmission towers more resilient to high winds. Several cities and states in Brazil have launched plans to prepare for climate change, but the bulk of these plans focus on increasing investments in renewable energy and emissions reduction. Increasingly, these plans will also need to focus on mitigating risk from floods, heat waves and landslides. Brazilian energy companies are also behind the curve in their preparations for climate change. Only 13pc of executives in the energy sector that participated in a recent survey conducted by consulting firm PwC Brasil said they have assessed the impact of climate change on their financial planning. State of climate Brazil faced 12 extreme climate events in 2023, according to the World Meteorological Association (WMO). This included a tropical cyclone that hit Rio Grande do Sul last year and affected more than 340,000 people and left nearly 50 dead. The WMO blamed the extreme climate events in Brazil on the "double-whammy of El Niño and longer-term climate change." Last year, eight Brazilian states recorded their lowest July-to-September rainfall in over 40 years, it said. Send comments and request more information at feedback@argusmedia.com Copyright © 2024.

Japan’s J-Power steps up coal-fired power phase-out
Japan’s J-Power steps up coal-fired power phase-out
Osaka, 10 May (Argus) — Japanese power producer and wholesaler J-Power is stepping up efforts to halt operations of inefficient coal-fired power plants, while pushing ahead with decarbonisation of its existing plants by using clean fuels and technology. J-Power plans to scrap the 500MW Matsushima No.1 coal-fired unit by the end of March 2025 and the 250MW Takasago No.1 and No.2 coal-fired units by 2030, according to its 2024-26 business strategy announced on 9 May. It also aims to decommission or mothball the 700MW Takehara No.3 and the 1,000MW Matsuura No.1 coal-fired units in 2030. The combined capacity of the selected five coal-fired units accounts for 32pc of J-Power's total thermal capacity of 8,412MW, all fuelled by coal. While phasing out its ageing coal-fired capacity, J-Power is looking to co-fire with fuel ammonia at the 2,100MW Tachibanawan coal-fired plant sometime after 2030 and ensure it runs on 100pc ammonia subsequently. The company plans to increase the mixture of biomass at the 600MW Takehara No.1 unit, along with the installation of a carbon capture and storage (CCS) technology after 2030. The CCS technology will be also applied to the 1,000MW Matsuura No.2 unit, which is expected to co-fire ammonia, after 2030. J-Power plans to use hydrogen at the 1,200MW Isogo plant sometime after 2035. The company is also set to deploy integrated coal gasification combined-cycle and CCS technology at the 500MW Matsushima No.2 unit and the 150MW Ishikawa No.1 and No.2 units after 2035. The company aims to cut carbon dioxide emissions from its domestic power generation by 46pc by the April 2030-March 2031 fiscal year against 2013-14 levels before achieving a net zero emissions goal by 2050. This is in line with Tokyo's emissions reduction target. The company aims to expand domestic annual renewable output by 4TWh by 2030-31 compared with 2022-23, along with decarbonising thermal capacity. Its renewable generation totalled 10.4TWh in 2023-24. Tokyo has pledged to phase out existing inefficient coal-fired capacity by 2030, which could target units with less than 42pc efficiency. The country's large-scale power producers have reduced annual power output from their inefficient coal-fired fleet by 13TWh to 103TWh in 2022-23 against 2019-20, according to a document unveiled by the trade and industry ministry on 8 May. It expects such power generation will fall further by more than 60TWh to 39.700TWh in 2030-31. Global pressure against coal-fired power generation has been growing. Energy ministers from G7 countries in late April pledged to phase out "unabated coal power generation" by 2035 or "in a timeline consistent with keeping a limit of 1.5°C temperature rise within reach, in line with countries' net zero pathways".

LNG imports loom as Australia unveils gas strategy
LNG imports loom as Australia unveils gas strategy
Sydney, 9 May (Argus) — Australia's federal government will attempt to reverse the decline in new gas developments by expediting projects, although a report has found it is unlikely to reverse an anticipated shortfall in southern states' supplies later this decade. Canberra's long-awaited Future Gas Strategy will form its future policy on the resource, following two years of uncertainty for the industrial sector. This follows the Labor party-led government's election in May 2022 and its dumping of the previous Liberal-National coalition administration's gas-fed recovery from Covid-19 policy, which emphasised bringing new supplies on line to drive down rising prices. Six principles have been outlined by the government — driving down emissions reductions to reach net zero emissions by 2050, making gas affordable for users during the transition, bringing new supplies on line, supporting a shift to "higher-value and non-substitutable gas uses", ensuring gas and power markets remain fit for purpose during the energy transition and maintaining Australia's status as a reliable trading partner for energy, including LNG. The report found that gas-fired power generation will likely provide grid firming as renewables replace older coal-fired plants. Peak daily gas demand could rise by a factor of two to three by 2043, according to projections, with gas-powered peaking generation labelled a "core component of the National Electricity Market to 2050 and beyond". But by the 2040s more alternatives to gas for peaking and firming are expected to become available. Supplies are forecast to dip significantly in the latter years of the decade, especially in gas-dependent southeast Australia, driven by the 86pc depletion of the region's producing fields. This reduced supplies will outpace a fall in demand , while rising demand is forecast because of the retirement of Western Australia's coal-fired power plants . The report found the causes of Australia's low exploration investment are "multifaceted", blaming the Covid-19 pandemic, difficulties with approvals processes , legal challenges, market interventions and a perceived decline in social licence. It added that international companies may focus on lower cost and lower risk fields in other countries. New sources Stricter enforcement of petroleum retention leases and domestic gas reservation policies are also likely to increase supplies, the report found, with term swap arrangements beneficial in increasing their certainty. Upwards pressure in transport costs is likely to result from increased piping of Queensland coal-bed methane gas to southern markets such as Victoria state, which could influence industrial users to relocate closer to gas fields in the future. Options canvassed to meet demand include more pipelines and processing plants and LNG import terminals , which would provide the fastest option but must overcome regulatory and commercial pressures, given the pricing of LNG would be higher than current domestic prices. Longer term supplies depend on the commerciality from unsanctioned projects such as Narrabri and in the Beetaloo and Surat basins, the report said. More supplies are needed to support exports under foundational LNG contracts, with an impact on the domestic market if Surat basin developments such as Atlas does not continue, the report said. Forecasts show LNG exporters have sufficient production from existing and committed facilities to meet forecast exports until 2027 if expected investments proceed. But beyond this new investment is required, especially for the 8.5mn t/yr Shell-operated Queensland-Curtis LNG at Gladstone. The Australian Energy Producers lobby, which represents upstream oil and gas businesses, said the strategy should now provide clear direction on national energy policy. But the Greens party, the main federal parliamentary group aside from Labor and the Liberal-National coalition, said any plans to continue gas extraction beyond 2050 will negate state and federal net zero 2050 climate targets.

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.
