Europe’s attempt to rebuild domestic supply chains for lithium, rare earths and battery metals is often described as a race to secure raw materials. Yet the decisive factor shaping where the continent’s new refining plants will actually be built may not be geology at all. It may be electricity.
Across lithium conversion facilities, copper refineries, graphite purification plants and rare-earth metal processing units, energy represents one of the most important operating costs. In some segments it is the single largest controllable component of operating expenditure. In others it is the factor that determines whether a refining plant can compete globally.
This reality is beginning to reshape the geography of Europe’s emerging midstream minerals industry.
Under the European Union’s Critical Raw Materials Act, the bloc aims to ensure that 40 % of strategic minerals are processed within Europe by 2030, reducing dependence on external refining capacity. Achieving that target will require dozens of new chemical conversion plants, metallurgical refineries and materials-processing facilities across the continent.
But as investors and industrial planners evaluate potential locations for these plants, one factor repeatedly dominates feasibility studies: the long-term price and stability of electricity.
The reason is simple. Many critical-mineral refining processes are highly energy intensive. Producing battery-grade graphite requires temperatures exceeding 2,500 °C. Copper smelting operates above 1,200 °C, while electro-refining processes consume large amounts of electricity continuously over extended production cycles. Even lithium chemical conversion plants require high-temperature roasting and energy-intensive crystallisation stages.
In these operations, electricity is not just another input. It is the backbone of the refining process.
In copper smelting and refining, energy costs can represent 20–30 % of operating expenditure, second only to the cost of the metal concentrate itself. Graphite purification and graphitisation processes are even more energy intensive, with electricity sometimes accounting for 30 % or more of total production costs.
For lithium conversion plants producing lithium hydroxide, energy plays a slightly smaller but still significant role, typically accounting for 10–15 % of operating costs, depending on plant design and energy prices. Rare-earth separation plants are less energy intensive but rely heavily on chemical reagents and solvent extraction systems that also require substantial energy inputs.
These cost structures help explain why refining capacity historically concentrated in regions with abundant and inexpensive energy.
China, which today dominates global rare-earth refining and graphite processing, built its midstream metals industry in provinces where electricity prices were relatively low and industrial power supply could be scaled rapidly. Indonesia’s recent expansion of nickel refining has similarly been supported by large coal-based power plants built specifically to supply metallurgical facilities.
Europe faces a different economic environment. Industrial electricity prices in many EU countries remain significantly higher than in competing regions, reflecting both energy-market structures and the cost of decarbonisation policies. For energy-intensive refining processes, these price differences can dramatically influence competitiveness.
As a result, companies planning new refining facilities are increasingly searching for locations where electricity prices are both predictable and internationally competitive.
This search is quietly reshaping the geography of Europe’s emerging critical-minerals industry.
The Nordic region has already positioned itself as one of the continent’s most attractive locations for battery-metal refining. Countries such as Finland and Sweden offer relatively stable electricity prices, strong renewable energy resources and long industrial traditions in metallurgy. Several battery-materials refineries and precursor plants are already operating or under construction in the region.
France is emerging as a hub for rare-earth refining and recycling, with projects such as the Caremag rare-earth recycling facility in the Lacq industrial cluster and expansions of existing processing capacity in La Rochelle. These facilities are supported by strong industrial infrastructure and proximity to European manufacturing centres.
Yet beyond these established industrial regions, another geography is beginning to attract attention as a potential midstream processing hub: Southeast Europe, and particularly Serbia.
The country’s industrial history provides an important starting point. Serbia hosts one of the largest metallurgical complexes in the region at Bor, where copper mining, smelting and refining have been central to the local economy for decades. The complex, now operated by Zijin Mining, integrates multiple mines with smelting and refining facilities capable of producing high-purity copper and precious metals.
This legacy has left Serbia with something that many European countries no longer possess: a workforce experienced in large-scale metallurgical processing and an industrial ecosystem familiar with the demands of heavy materials production.
Energy economics further strengthen the country’s potential role in Europe’s refining landscape.
Industrial electricity prices in Serbia generally range between €0.14 and €0.18 per kilowatt-hour, depending on contract structures and consumption levels. While not the lowest globally, these levels remain competitive compared with many Western European industrial markets.
The structure of the country’s energy system also plays an important role. Serbia’s electricity generation includes significant hydropower capacity, complemented by large baseload thermal plants that provide stable supply. For industrial consumers operating energy-intensive processes such as electro-refining or graphite purification, access to consistent baseload electricity is often as important as the price itself.
In addition, the country’s position within Southeast Europe places it at the centre of a regional electricity trading network connecting Central European, Balkan and Adriatic power markets. This interconnected grid allows industrial consumers to benefit from cross-border electricity flows and regional market dynamics.
These factors are increasingly relevant as Europe attempts to build new refining capacity across multiple critical minerals.
Lithium conversion plants represent one of the most urgent priorities. Europe’s electric-vehicle industry is expanding rapidly, with battery gigafactories under construction across Germany, France, Hungary and Poland. Yet the continent still lacks sufficient capacity to convert lithium ores into battery-grade chemicals such as lithium hydroxide and lithium carbonate.
Several lithium conversion plants are already planned or under construction in Germany, Finland and Portugal. However, as demand grows, additional facilities may be required to supply Europe’s rapidly expanding battery manufacturing sector.
For such plants, energy costs can significantly influence operating economics. Lithium conversion involves high-temperature roasting and chemical purification processes that require continuous heat and electricity. Locations offering stable industrial electricity supply at competitive prices therefore become particularly attractive.
Rare-earth processing presents another potential opportunity. Permanent magnets made from rare-earth elements such as neodymium and praseodymium are essential components of electric-vehicle motors and wind turbines. Europe currently operates only a handful of rare-earth separation facilities, leaving most magnet materials imported from Asia.
Building a European rare-earth processing chain requires multiple stages, including oxide separation, metal reduction and alloy production. Each of these processes consumes significant energy and relies on specialised metallurgical expertise.
Serbia’s existing metallurgical capabilities could provide a foundation for hosting some of these processing stages, particularly metal reduction and alloy production, which require high-temperature furnaces and experienced industrial operators.
Graphite processing is another segment where energy economics play a decisive role. Producing battery-grade graphite requires high-temperature purification and graphitisation processes that can consume large amounts of electricity. As Europe attempts to reduce dependence on imported graphite anode materials, new processing plants will need to be located in regions where energy costs remain manageable.
For Southeast Europe, this emerging industrial opportunity extends beyond individual refining plants. The broader vision involves the creation of a regional metallurgical processing corridor, linking mining projects across the Balkans and Eastern Europe with refining hubs and manufacturing centres.
In this scenario, mineral concentrates from across Europe and neighbouring regions could be processed in a network of midstream facilities located in energy-competitive industrial zones. Serbia’s geographic position—situated between Central Europe, the Balkans and the Mediterranean—could allow it to play a role in such a network.
Yet energy economics remain the decisive variable. The success of Europe’s midstream minerals strategy will depend heavily on whether refining plants can secure long-term electricity supply at prices that allow them to compete with producers elsewhere in the world.
For policymakers, this creates a complex challenge. Europe’s energy transition aims to reduce carbon emissions while expanding renewable electricity generation. At the same time, the continent must ensure that energy-intensive industries such as refining remain economically viable.
Some countries are exploring long-term power contracts between renewable energy producers and industrial consumers, allowing refining plants to secure stable electricity prices while supporting the development of new renewable capacity. Others are considering special industrial electricity tariffs for strategic sectors such as battery materials and critical-minerals processing.
The underlying reality is that the geography of Europe’s refining industry will ultimately be determined not only by mineral deposits or industrial policy but also by electricity prices.
The continent’s energy transition depends on metals. But refining those metals requires power.
In the coming decade, the places where affordable and reliable electricity can be combined with metallurgical expertise will likely become the new centres of Europe’s midstream minerals industry. As companies search for those locations, Serbia’s combination of industrial heritage, energy infrastructure and geographic position may increasingly attract attention.
The energy transition is often described as a shift from fossil fuels to renewable power. Yet in industrial terms it is also a shift toward energy-intensive materials processing. The countries able to supply both the electricity and the metallurgical capability required for that transformation will help shape the industrial map of Europe’s electrified future.
