BHP to expand gas-fired West Australia power station

  • Market: Electricity, Natural gas
  • 17/04/24

Australian resources firm BHP plans to increase power generation at its 154MW Yarnima gas and diesel-fired facility near the Pilbara iron ore mining hub of Newman in Western Australia (WA) state.

The proposal, according to documents filed with WA's Environmental Protection Authority (EPA), will see output increase by 85MW to a total of 239MW through gas reciprocating engines and associated infrastructure with up to 120MW of nominal new capacity to be built in stages.

Peak scope 1 greenhouse gas (GHG) emissions from the project are predicted to be 480,030 t/yr of carbon dioxide equivalent (CO2e), while scope 3 emissions related to supplying the gas are expected to be 37,260t CO2e/yr.

Power demand at BHP's iron ore operations in the Pilbara is forecast to increase from 150MW currently to 1GW by 2040, as the company reduces its GHG emissions through electrification of its rail and mining fleets and must balance renewables with firmed generation.

The iron ore mining sector is a large-scale producer of Australian GHG emissions through its Pilbara-based operations. Displacing liquid fuels such as diesel, which Australia consumes at an average rate of around 500,000 b/d by electrifying processes and switching to lower CO2-emitting sources such as gas, is expected to trend as Australia's largest polluters meet government mandates. Yarmina currently runs a 35MW diesel-fired temporary power station as part of its installed capacity.

Canadian energy firm TransAlta earlier this year lodged plans to build a new 150MW gas-fired power station for BHP's Nickel West operations in WA's Northern Goldfields region.

WA's domestic market is likely to be short on gas later this decade despite being Australia's largest LNG export state, the Australian Energy Market Operator (Aemo) has warned in its Western Australia Gas Statement of Opportunities. Aemo's modelling released last year shows the closure of WA's state-owned coal-fired power stations will drive increased requirements for gas-fired electricity generation in the next decade.

FinBalt gas demand down on the year in April

FinBalt gas demand down on the year in April

London, 8 May (Argus) — Combined gas demand across the Finnish and Baltic region fell by 4pc on the year in April despite gas-fired power generation rising by nearly 50pc. Aggregate consumption in Finland, Estonia, Latvia and Lithuania in April fell to 3.42TWh, down from 3.56TWh the previous year and the three-year average of 5.12TWh in 2019-21. That said, it was still higher than in both 2022 and 2023 ( see consumption graph ). Lithuania remained the region's largest consumer, as it has been for every month since June, again driven by an increase in gas-fired power generation. Average gas-fired output soared by nearly 400pc on the year in April to 254MW according to data from Fraunhofer ISE, more than making up for a 43pc drop in Finnish production ( see power table ). Following the de-synchronisation of the Baltic states from the post-Soviet Brell system, gas-fired power plants have become particularly important in the region, not just for producing electricity but also for providing ancillary services such as frequency reserves. Lithuania has the largest gas-fired fleet in the region, and its output jumped despite domestic power consumption falling by more than 5pc on the year and renewable output increasing, which allowed the country to cut its power imports last month to 104MW, from 546MW in the previous year. With power sector gas demand increasing in April but overall gas consumption in the region dropping, demand from households and industries must have been lower on the year. Weather patterns were split across the region, with lower average minimum temperatures than the previous year in Vilnius and Riga, but higher in Tallinn and Helsinki. That said, overnight lows in all four capitals were still above the 2015-24 average last month, limiting strong heating demand in the shoulder month ( see temperature table ). Traded volumes on the region's gas exchange GET Baltic rose to 1.1TWh last month, an "unusually high result for this time of year" according to the exchange's senior account manager Karolis Bagdonas. Of the overall volume, 56pc traded in Lithuania, 28pc in the joint Estonia-Latvia market area, and the remaining 16pc in Finland. The average price on GET Baltic was €39.40/MWh last month, down by around 8pc from March. GET Baltic announced in April that its full integration into the European Energy Exchange (EEX) had been delayed again until 9 September , having previously been planned for 27 May . Across all of January-April FinBalt consumption totalled 18.43TWh, down from 20.04TWh in the same period of 2024. Stocks at the region's only storage facility in Latvia ended the storage year on 1 May at 8.4TWh, below 11.3TWh on the same day last year and 9TWh in 2023, but still above all other years since 2018 ( see data and download ). The entire 100pc of capacity, amounting to just over 23TWh, had been booked for the 2024-25 storage year, but for the new 2025-26 cycle a lower 17TWh has been allocated, representing around 68pc of the cycle's total technical capacity of 24.9TWh. Consistently positive summer-winter spreads over the winter period, which gave no financial incentive to book storage, may have driven lower interest in 2025-26 capacity, although they had normalised by April. Lower overall booked volumes is despite operator Conexus managing to sell all 9TWh of the new five-year capacity product it offered in February and March . Slow start to injection season Injections into Incukalns have been weak so far this year, with not a single day of net injections until 24 April. In the previous year, there had been some brief net injections on 1-4 April at an average of 54 GWh/d, and across all of April they averaged just over 7 GWh/d. In contrast, this year's April averaged net withdrawals of 32 GWh/d across the month, with injections only on 24-30 April. This slow stockbuild has continued in the first week of May, with 35GWh of net injections on 1 May but then a flip back to very minor net withdrawals of 0.2 GWh/d on every day of 2-6 May, the latest data from GIE show. Last year, there were average net injections of 47 GWh/d on 1-6 May, and 39 GWh/d in 2021-23. Despite weak injections, overall LNG sendout across the region's three terminals of Klaipeda, Inkoo and Hamina has increased significantly from April, nearly doubling to 150 GWh/d on 1-7 May from 80 GWh/d in April. Sendout from these terminals averaged 84 GWh/d on 1-7 May last year. Rather than injecting all of the regasified LNG, some of it is being sent southward to Poland at Santaka, with exit flows at the point averaging 22 GWh/d on 1-7 May, switched from net inflows of 2 GWh/d in April. This is likely to be linked to Polish incumbent Orlen's deals to supply LNG to Ukraine's Naftogaz, of which one of the contracts specified that it would be delivered to Klaipeda and transited to the Ukrainian border .

Japan’s Erex to build biomass power plant in Cambodia

Tokyo, 8 May (Argus) — Japanese renewable energy developer Erex aims to start constructing a 50MW biomass-fired power plant in Cambodia in mid-2025, the company told Argus today. The plant in southern Cambodia's Kampong Speu province will be the first biomass-fired power project for Erex in the country. It is scheduled to start commercial operations in the 2027-28 fiscal year, and will burn domestic wood chips and agricultural residues to generate around 350 GWh/yr. The Cambodian government will purchase all the electricity generated at the plant for 25 years after its start-up. Erex plans to build up to five biomass-fired power plants which will burn domestic biomass fuels, as well as several wood pellet factories in Cambodia. The government expects these projects to raise the country's energy security. Erex on 23 April began commercial operations at the 20MW Hau Giang biomass-fired power plant in southern Vietnam, its first biomass-fired power project in the country. Erex aims to construct up to 18 biomass-fired power plants in Vietnam, following Hau Giang. The company has already started constructing two 50MW plants in northern Vietnam. Erex also started wood pellet production at its first factory in Vietnam in March, with a capacity of 150,000 t/yr. The company plans to build up to 20 wood pellet factories in the country. Erex's profits from projects in Vietnam and Cambodia are expected to grow rapidly and could account for more than half of its total profits by around 2030, according to the company, and the projects would also contribute to both countries' decarbonisation efforts.

Australian renewable projects gain power grid access

Sydney, 8 May (Argus) — A total of 10 renewable energy projects have been granted access to a power grid in New South Wales (NSW), Australia, to avoid over 10mn t/yr of CO2 equivalent (CO2e) of emissions by 2031, the NSW state government said today. The 10 private solar, wind and battery storage projects will connect to the Central-West Orana Renewable Energy Zone (REZ) , a 20,000 km² area about 400 km west of state capital Sydney that will avoid 10.29mn t/yr of carbon emissions, according to the state's energy minister. Construction of the 240 km transmission line connecting the renewable energy projects to the national electricity market will start in mid-2025 and is estimated to cost A$3.2bn ($2.1bn). The 10 projects will provide total renewable energy and storage capacity of 7.15 GW, capable of powering over half the households in NSW by 2031. The Central-West Orana REZ is expected to be completed by December 2028 and is part of the NSW's transition to renewable energy. The REZ is expected to generate 15,000 GWh/yr of energy when fully operational, around 5pc of the total 273,000 GWh generated in the country in 2023, according to the Australian Department of Environment. The REZ improves the state's chances of meeting its target of reducing emissions by 50pc from 2005 levels by 2030 through lowering its reliance on coal-fired generation, which accounted for 70pc of fuel used in NSW in May 2024-April 2025. Australia's largest coal-fired power station Origin's 2,880 MW Eraring provides 18pc of the state's electricity and will close in August 2027, around a year before the expected completion of the Central West Orana REZ project.

IMO GHG pricing falls short on green methanol, ammonia

IMO GHG pricing falls short on green methanol, ammonia

New York, 7 May (Argus) — The International Maritime Organization's (IMO) proposed global greenhouse gas (GHG) pricing mechanism might not drive significant uptake of green methanol and green ammonia by 2035, given current market prices. Despite introducing penalties on high-emission fuels use and tradable surplus credits for low-emission fuels, the mechanism does not sufficiently close the cost gap for green alternatives. Under the system, starting in 2028 ship operators will face a two-tier penalty: $100/t CO₂e for emissions between the base and direct GHG intensity limit, and $380/t CO₂e for those exceeding the looser base limit. These thresholds will tighten annually through 2035. Ship operators can earn tradable credits for overcompliance when their GHG emissions fall below the direct limit. Assuming a surplus CO₂e credit value of $72/t — mirroring April 2025's average EU emissions trading system price — green ammonia would earn about $215/t in surplus credits in 2028 (see chart) . This barely offsets its April spot price of $2,830/t VLSFO equivalent in northwest Europe. Bio-methanol would receive about $175/t in credits, offering minimal relief on its $2,318/t April spot price. Currently, unsubsidized northwest Europe bio-LNG sits mid-range among bunker fuel options under IMO's emissions framework. While more expensive than HSFO, grey LNG, and B30 bioblends, the bio-LNG is cheaper than B100 (pure used cooking oil methyl ester), green ammonia, and bio-methanol. To become cost-competitive with unsubsidized bio-LNG — priced at $1,185/t in April 2025 — green ammonia and bio-methanol prices would need to fall by 57pc and 49pc, respectively, to around $1,220/t VLSFOe and $1,180/t VLSFOe by 2028. Unless green fuel prices drop significantly or fossil fuel prices rise, the IMO's structure alone provides insufficient economic incentive to accelerate green ammonia and bio-methanol adoption at scale.

UK, Norway pursue further ‘green industry’ co-operation

London, 7 May (Argus) — The UK and Norway have signed an early-stage agreement for a "green industrial partnership", planning to work together on low-emissions technology such as offshore wind, carbon capture and storage (CCS) and hydrogen. The partnership will "strengthen energy security" and "support robust value chains for raw materials", the Norwegian government said. The collaboration also aims to "support the development of renewable energy sources, and further develop existing cooperation on the protection of subsea infrastructure in the North Sea", Norway's government added. Both Norwegian and UK representatives are in attendance at the Copenhagen climate ministerial this week — an event which often sets the direction for climate negotiations this year. The countries in December flagged their intent to partner on the energy transition, including developing an agreement on cross-border CO2 transport. Norway is a leader in Europe's developing CCS sector. The country's flagship Northern Lights CCS project is due to begin operating this summer. The project's partnership this week confirmed that all required permits are in place for the injection and storage of CO2.
