Australia’s Origin buys 1.5GW wind, battery project
Australian upstream and utility firm Origin Energy has entered an agreement with renewables developer Virya Energy to acquire the 1.5GW wind, 800MWh battery Yanco Delta project in New South Wales (NSW).
Origin will pay up to A$300mn ($194mn) for the project, starting with an upfront payment of A$125mn and an additional payment of up to A$175mn dependent on Yanco Delta achieving some development milestones.
Yanco Delta — one of the largest and most advanced wind and energy storage projects in NSW — will allow Origin to bring a "material volume of renewable energy supply into the market relatively quickly", chief executive officer Frank Calabria said. Yanco Delta received development approval from the NSW government last December and federal approval under the Environment Protection and Biodiversity Conservation (EPBC) Act in February, with grid connection rights expected to be the next major milestone for the project.
"Securing transmission access rights is a key near term priority for the project, which subject to the timing of the access rights tender process, we anticipate occurring before the end of the 2024," an Origin spokesperson told Argus on 15 April. "Timing for development will ultimately be confirmed once we have all aspects of the project finalised, EPC contractors engaged, and a final investment decision is taken."
The Australian Energy Market Operator (Aemo) manages access rights via a competitive tender process. Virya Energy previously said it expected the final investment decision and the start of construction for 2025-26, with completion between 2027-29.
Yanco Delta will be located some 10km northwest of Jerilderie in the Riverina district, in NSW's South West Renewable Energy Zone (REZ). It could be one of the biggest renewable plants helping to replace ageing coal-fired plants in NSW, with three of the four remaining facilities in the state — Origin's 2,880MW Eraring, utility AGL's 2,640MW Bayswater and utility Delta Electricity's 1,320MW Vales Point — expected to close over the next decade. Virya Energy estimates Yanco Delta could avoid between 3.3mn-4.5mn t/yr of greenhouse gas (GHG) emissions.
Origin was the fourth largest GHG emitter in the 2022-23 fiscal year to 30 June, according to the Clean Energy Regulator (CER). The utility has been in talks with the NSW government to extend Eraring's operations beyond its planned August 2025 closure, while stepping up renewable investments in recent months. It in February acquired developer Walcha Energy, which is developing the Ruby Hills wind and Salisbury solar projects with more than 1.3GW of combined capacity.

Biomass start-ups lift Japan's Renova April power sales
Tokyo, 17 May (Argus) — Japanese renewable power developer Renova's electricity sales doubled on the year in April, following the start-up of three biomass power plants in the past six months. Renova sold 199,601MWh of electricity — including solar, biomass and geothermal — in April, double the 99,857MWh a year earlier, the company announced on 13 May. The 75MW Sendai Gamo plant in northeastern Miyagi prefecture started operations in November 2023 and produced 40,753MWh in April. The 74.8MW Tokushima Tsuda plant in western Tokushima prefecture, which was commissioned in December 2023, generated 10,870MWh in April. The 75MW Ishinomaki Hibarino plant in Miyagi began normal runs in March and supplied 49,495MWh in April. Renova plans to add 124.9MW biomass-fired capacity in the April 2024-March 2025 fiscal year, with the 75MW Omaezaki plant in central Shizuoka city scheduled to begin commercial operations in July, followed by the 49.9MW Karatsu plant in southern Saga city in December. Omaezaki is currently conducting trial runs and Karatsu is under construction. The additions will increase Renova's biomass-fired capacity to 445MW.

Mexican power outages enter fourth day
Mexican power outages enter fourth day
Mexico City, 10 May (Argus) — Mexican power grid operator Cenace issued its fourth consecutive day of operating alerts amid the heatwave gripping the country. Net electricity demand reached 47,321MW early today, with deployed electricity capacity slightly below at 47,233 MW, according to Cenace. Since 7 May, Cenace has declared emergency operating alerts as demand exceeded generation capacity during peak evening hours, prompting the grid operator to preemptively cut electricity supply across different states to maintain grid integrity. Power outages have lasted up to several hours in Mexico City and in major industrial states as power demand has outstripped supply by up to 1,000MW. Peak demand this week hit 49,000MW, just below last year's historic peak of 53,000MW during atypical temperatures in June. "We are very concerned about the unprecedented outages detected across 21 states, a situation that affects the normal functioning of Mexican companies," national business chamber Coparmex said. Peak electricity demand typically rises in June-July but temperatures this week have risen as high as 48°C (118° F) across some states. Mexico City reported a record high of 34.3°C on 9 May and high temperatures are forecast to continue into next week, Mexico's national weather service said. The inability of Mexico's grid to respond to increased demand is because of insufficient power generation capacity, non-profit think-tank the Mexican institute for competitiveness (Imco) said this week. "Despite the energy ministry's forecast that 22,000MW of new power capacity would enter service by 2026, only 1,483MW had entered service as of 2022" since late 2018, Imco said. President Andres Manuel Lopez Obrador's administration pledged to build new generation capacity, including five gas-fired, combined-cycle plants, but recognized this week that delays had contributed to the power outages. "We have an electricity generation deficit because some of the combined-cycle plants were delayed, but we are working on it and it will soon be resolved," Lopez Obrador said on 9 May. Lopez Obrador's government has also curtailed private sector power development during his administration. Mexico needs to upgrade and expand its transmission network, industry associations say. "In order to resolve this problem, we believe that a reopening of the electricity market to the private sector is imperative," Mexico's wind energy association, Amdee, said. Mexico has 87,130MW of installed capacity, with 39.5pc from combined-cycle gas-fired power plants and 31pc in renewable power, including wind, solar, hydroelectric, geothermal and biomass, according to the latest statistics from the energy ministry.

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 state R19bn ($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 2023warned 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".
