Column: Energy issues rein in international aluminium output development: Andy Residence

LONDON, Jan 23 (Reuters) – International aluminium manufacturing rose by a marginal 2.0% final yr, a fee of development that was down from 2.7% in 2021 and the slowest since 2019, in response to the Worldwide Aluminium Institute (IAI).

Output barely rose at everywhere in the second half of the yr. Annualised manufacturing of 69 million tonnes in December was simply 231,000 tonnes greater than June’s international run-rate.

Europe’s power disaster has taken a heavy toll on a notoriously power-hungry sector. Regional manufacturing fell by 12.5% final yr, a significant component behind the 0.9% decline in output outdoors of China.

China, the world’s dominant producer of major aluminium, registered 4.0% output development for the second consecutive yr.

But it surely too has been grappling with energy issues, most lately within the hydro-rich provinces of Yunnan and Sichuan. The nation’s annualised manufacturing peaked in August 2022 at 41.46 million tonnes, since when run-rates have fallen by 600,000 tonnes.

Aluminium’s power paradox is coming into ever sharper focus. Manufacturing of a metallic that’s important for constructing a greener energy system is itself more and more susceptible to fluctuating energy availability.

EUROPE POWERS DOWN

Western European aluminium output was working at an annualised 2.73 million tonnes in December, down by 540,000 tonnes on December 2021 and the bottom manufacturing fee this century.

Russia’s invasion of Ukraine and the ensuing surge in energy costs induced a number of smelter closures and curtailments final yr.

Europe’s power crunch has now handed its peak. German baseload energy for 2024 supply has fallen from 470 euros/MWh in August to a present 189.

Some European aluminium capability is returning. The Dunkerque plant, one of many area’s largest with capability of 285,000 tonnes per yr, is reversing the 20% cuts made within the fourth quarter of 2022.

For some, although, it is in all probability too late.

Slovakia’s sole smelter with capability of 175,000 tonnes per yr has closed all major operations after 70 years of operation.

The Podgorica smelter in Montenegro closed the final 60,000 tonnes of major capability on the finish of 2021.

Curiously, each vegetation are counted within the IAI’s Jap Europe and Russia class. So too are smelters in Romania and Slovenia, each of which have drastically curtailed operations during the last yr.

But regional manufacturing was down by only one.4% final yr, a counterintuitive consequence until the closures have been offset by greater output in Russia.

That is potential given Rusal was planning to fireside up its new Taishet plant final yr, though there was no latest replace on the 428,500-tonne per yr mission.

STOP START IN CHINA

China’s manufacturing of 40.39 million tonnes of aluminium final yr was a brand new annual file however the headline masks appreciable chop and alter within the nation’s base smelter community.

New capability was introduced on stream and mothballed capability restarted in some provinces, whereas in others energy restrictions translated into obligatory curtailments for smelter operators.

The steadiness flipped from quick development within the first half of 2022 to sliding output over the closing months.

This yr has seen no repeat of the blanket restrictions imposed throughout the 2021 winter power crunch however drought within the southwest of the nation is weighing on smelter working charges. Some two million tonnes of capability in Yunnan, Sichuan and Guizhou was off-line on the finish of 2022, in response to Shanghai Steel Market.

It is unlikely to return till the second quarter, when the wet season ought to restore depleted reservoir ranges within the area’s hydro energy system.

There’s nonetheless loads of room for manufacturing development in China with the federal government capability cap of 45 million tonnes not but reached.

Nevertheless, the final two years have proven that it’s more and more uncommon for China to run at its current capability for any extended time period earlier than energy restrictions of 1 type or one other are imposed by provincial governments trying to steadiness power hundreds.

GREEN PRESSURE

It is noticeable that the drought issues in China’s southwest have not deterred aluminium producers from transferring capability there from coal-powered provinces within the quest for metallic with a decrease carbon footprint.

The stress to go inexperienced can also be turning into a key think about smelter restarts in the remainder of the world.

Latin America was the fastest-growing aluminium manufacturing area final yr with output up 10.7% yr on yr. A key driver was the restart of the Alumar smelter in Brazil primarily based on a swap to renewable energy. Ramp-up is taking a bit longer than planned, in response to 40% proprietor South32 (S32.AX), which isn’t stunning for the reason that plant final operated seven years in the past.

Alcoa (AA.N), which owns the balancing 60% stake in Alumar, can also be hoping to restart its San Ciprian smelter in Spain after a swap to renewable power. It has secured two wind-power offers which might cowl 75% of power wants for the 228,000-tonne per yr plant.

Even Slovalco could be resuscitated by Norwegian proprietor Hydro (NHY.OL) if the Slovak authorities can implement the European Union’s framework on carbon compensations.

POWER PARADOX

But the push for renewable energy merely accentuates the core aluminium paradox. As ever extra smelters swap to inexperienced power sources, international aluminium manufacturing is ever extra depending on seasonally variable energy availability.

Furthermore, seasonality itself is altering as international warming brings each longer droughts and warmer summer season warmth waves, which mix to raise power utilization whereas miserable energy technology.

It has turn into clear in the previous few years that China’s aluminium smelters, together with different power-intensive industries, are first in line for mandated curtailments when a province is making an attempt to steadiness its grid.

Such regional changes at the moment are half and parcel of the worldwide aluminium manufacturing panorama however they’ve injected a brand new diploma of volatility into aluminium’s beforehand slow-changing provide aspect.

Additionally they elevate the chance that China’s seemingly unstoppable aluminium juggernaut has run out of highway even earlier than reaching the federal government’s capability cap.
