Australia Callide C coal unit delays return: Correction
Corrects JV partner for Callide C from "InterGen Australia" to "Genuity" in 2nd paragraph.
The troubled Callide C coal-fired power station in the Australian state of Queensland will remain off line until 2024, in a blow to the country's east coast electricity users.
C3 and C4, the two 466MW units of Callide C located at Biloela, 420km north of the state capital Brisbane, are being rebuilt since an explosion in 2021 highlighted problems at the C4 unit. State-owned CS Energy, which operates the Callide C joint venture on behalf of Genuity — formerly known as InterGen Australia — authorised the demolition and rebuilding of the C3 and C4 cooling towers following the failure.
The C4 unit was scheduled to return to part capacity from 31 October this year and full capacity from 31 January 2024, but CS Energy revised those dates to 19 May 2024 and 6 July 2024, respectively.
The C3 unit, which was projected to reach partial capacity on 30 September and full capacity on 31 December this year, will now return to 50pc capacity on 7 January and full capacity on 18 February 2024. The unit suffered a structural failure of the cooling plant in October last year.
CS Energy said updated time frames for the two units follow advice from independent technical experts on the cooling tower rebuilding project, which received revised tenders earlier this year. The company said the new return-to-service dates reflected its priority of returning unit C3 for the peak summer demand period in early 2024, before tackling more difficult recommissioning of the rebuilt C4 unit.
Acting chief executive Andrew Varvari said he accepts that the performance of Callide C's generating units had not been good enough and must be improved. New management is in place in key areas of the business, to improve the performance of the Callide C units alongside a targeted maintenance programme, he added.
"CS Energy is acutely aware of the importance of reliable generation from coal-fired generators such as the Callide C power station, particularly at a time of high gas and coal prices and with reducing coal generation across the energy sector," Varvari said.
Black coal fuels most of Queensland's network, which is part of the eastern Australian National Electricity Market (NEM), but closures of older power stations and weak performance at others has led to increased demand from gas-fired plants.
The country needs to install 45GW of new supply by 2030 to replace coal-fired power stations likely to close in the coming years, the Australian Energy Market Operator (AEMO) has said. Queensland's government has committed to closing all coal-fired power generation by 2035.

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

Brazil hydroelectric dam bursts under record rains
Brazil hydroelectric dam bursts under record rains
Sao Paulo, 3 May (Argus) — Brazilian power generation company Companhia Energetica Rio das Antas (Ceran) found a partial rupture in its 100MW 14 de Julho hydroelectric plant following record precipitation in Rio Grande do Sul state. Flooding from the record rains has left 37 dead and forced more than 23,000 people out of their homes, causing widespread damage across the state, including washed out bridges and roads across several cities. Ceron reported that the dam of the hydroelectric plant on the Antas River suffered a rupture under the heavy rains and the company implemented an emergency evacuation plan on 1 May. Ceron's 130MW Monte Claro and 130MW Castro Alves plants are under intense monitoring, the company said in a statement. Rio Grande do Sul state governor Eduardo Leite declared a state of emergency and the federal government promised to release funding for emergency disaster relief. Leite said the flooding will likely go down as the worst environmental disaster in the state's history. Brazil's southernmost state along the border with Argentina has been punished by record precipitation over the past year owing to the effects of the strong El Nino weather phenomenon, according to Rio Grande do Sul-based weather forecaster MetSul Meteorologia. Brazilian power company CPFL Energia controls Ceran with a 65pc equity stake. Energy company CEEE-GT, which is owned by steel manufacturer CSN, owns another 30pc, and Norway's Statkraft owns the remaining 5pc. The state had declared a state of emergency as recently as September 2023 because of unusually heavy rains that resulted in the death of more than 30 people. Weather forecasters expect El Nino conditions to abate in the coming months over the eastern Pacific. Send comments and request more information at feedback@argusmedia.com Copyright © 2024.

Chevron’s oily DJ basin buy boosts gas output
Chevron’s oily DJ basin buy boosts gas output
New York, 3 May (Argus) — Chevron's US natural gas production has surged in recent quarters due to its crude-focused acquisition of Denver-based PDC Energy last August, increasing the oil major's exposure to the US gas market months after that market entered an extended price slump. Chevron's US gas production in the first quarter was 2.7 Bcf/d (76mn m3/d), up by 53pc from the year-earlier quarter and the highest since at least 2021, according to company production data. Chevron's total US output rose by 35pc year-over-year to 1.57 b/d of oil equivalent (boe/d), while US crude output increased by 21pc to 779,000 b/d. The acreage Chevron picked up last year in the DJ basin of northeast Colorado and southeast Wyoming has higher gas-oil ratios than the rest of its US portfolio. Chevron mostly focuses US production in the crude-rich Permian basin of west Texas and southeast New Mexico. Since Chevron closed its acquisition of PDC on 7 August, US gas prices have mostly languished in loss-making territory. Prompt-month Nymex gas settlements at the US benchmark Henry Hub from 7 August 2023 to 2 May 2024 averaged $2.46/mmBtu, down from an average of $4.999/mmBtu in the year-earlier period. In a May 2023 conference call over Chevron's acquisition of PDC, chief executive Mike Wirth expressed optimism for the long-run outlook for natural gas, despite the more immediately dim outlook. "There's going to be stronger global demand for gas growth than there will be for oil over the next decade and beyond as the world looks to decarbonize," Wirth said. Despite lower US gas prices, Chevron has captured $600mn in cost savings from the PDC acquisition between capital and operational expenditures, the company told Argus . Crude prices have also been more resilient. Chevron's profit in the first quarter was $5.5bn, down from $6.6bn in the year-earlier quarter, partly due to lower gas prices. US gas prices have been lower this year as unseasonably warm winter weather and resilient production have created an oversupplied US gas market. A government report Thursday showed US gas inventories up by 35pc from the five-year average. By Julian Hast Send comments and request more information at feedback@argusmedia.com Copyright © 2024.

US job growth nearly halved in April: Update
US job growth nearly halved in April: Update
Adds services PMI in first, fifth paragraphs, factory PMI reference in sixth paragraph. Houston, 3 May (Argus) — The US added fewer jobs in April as the unemployment rate ticked up and average earnings growth slowed, signs of gradually weakening labor market conditions. A separate survey showed the services sector contracted last month. The US added 175,000 jobs in April, the Labor Department reported today, fewer than the 238,000 analysts anticipated. That compared with an upwardly revised 315,000 jobs in March and a downwardly revised 236,000 jobs in February. The unemployment rate ticked up to 3.9pc from 3.8pc. The unemployment rate has ranged from 3.7-3.9pc since August 2023, near the five-decade low of 3.4pc. The latest employment report comes after the Federal Reserve on Wednesday held its target lending rate unchanged for a sixth time and signaled it would be slower in cutting rates from two-decade highs as the labor market has remained "strong" and inflation, even while easing, is "still too high". US stocks opened more than 1pc higher today after the jobs report and the yield on the 10-year Treasury note fell to 4.47pc. Futures markets showed odds of a September rate cut rose by about 10 percentage points to about 70pc after the report. Services weakness Another report today showed the biggest segment of the economy contracted last month. The Institute for Supply Management's (ISM) services purchasing managers index (PMI) fell to 49.4 in April from 51.4 in March, ending 15 months of expansion. The services PMI employment index fell to 45.9, the fourth contraction in five months, in today's report. Readings below 50 signal contraction. On 1 May, ISM reported that the manufacturing PMI fell to 49.2 in April, after one month of growth following 16 months of contraction. In today's employment report from the Labor Department, average hourly earnings grew by 3.9pc over the 12 month period, down from 4.1pc in the period ended in March. Job gains in the 12 months through March averaged 242,000. Gains, including revisions, averaged 276,000 in the prior three-month period. Job gains occurred in health care, social services and transportation and warehousing. Health care added 56,000 jobs, in line with the gains over the prior 12 months. Transportation and warehousing added 22,000, also near the 12-month average. Retail trade added 20,000. Construction added 9,000 following 40,000 in March. Government added 8,000, slowing from an average of 55,000 in the prior 12 months. Manufacturing added 9,000 jobs after posting 4,000 jobs the prior month. Mining and logging lost 3,000 jobs.
