Guinea’s plan to expand domestic processing of its bauxite is confronting a major electricity challenge, with the country generating approximately 1,000 MW of power against an estimated 5,000–10,000 MW needed to support its wider industrialisation ambitions. The gap threatens to complicate plans to build alumina refineries and, eventually, aluminium smelters as the West African country seeks to capture more value from its mineral resources instead of exporting predominantly unprocessed ore. The estimates were outlined by Daouda Diakité, a senior adviser to Guinea’s mines minister, during African Mining Week in Cape Town.
The government wants five alumina refineries operating by 2030, with combined annual production capacity of between seven million and eight million tonnes. Three projects are already under construction, according to Diakité. The target forms part of Guinea’s broader Simandou 2040 strategy to expand domestic mineral processing, alongside plans to develop iron ore pellet plants, steel production and other industries. Guinea has recently overtaken Australia as the world’s largest bauxite producer and exporter, but turning that resource advantage into industrial production requires substantial investment in processing facilities and supporting infrastructure.
Electricity is a particular constraint because Guinea’s power supply depends heavily on hydropower and varies seasonally. The country can export electricity to neighbouring markets during the rainy season, which generally runs from April or May to November, but imports power from Côte d’Ivoire or Senegal during drier months. That variability creates a challenge for industrial facilities that need dependable energy throughout the year. New refineries will add demand to a system that must also supply households, existing businesses and other planned industrial developments.
The distinction between alumina refining and aluminium smelting is important to the scale of the challenge. Alumina refineries convert bauxite into alumina, an intermediate product used to manufacture aluminium. Smelters then use an electricity-intensive process to turn alumina into metal, requiring a much larger and more continuous power supply. Diakité’s estimate of 5,000–10,000 MW relates to Guinea’s broader industrialisation ambitions, including future aluminium smelting; it should not be interpreted as the confirmed electricity requirement of the five planned refineries alone. The two stages of production therefore present different energy requirements and investment decisions.

Guinea is considering multiple energy options to support industrial growth, including gas, coal and nuclear power, according to Diakité. The country does not produce coal domestically, and he suggested that vessels arriving to load bauxite could potentially transport coal from South Africa or Mozambique. Such options would require further development and commercial assessment. Expanding generation capacity would also need to be accompanied by transmission and distribution infrastructure capable of delivering reliable electricity to industrial sites. Without those investments, additional power generation may not translate into a dependable supply for processing plants.
The challenge extends beyond Guinea. Across Africa, governments are encouraging mining companies to process minerals locally through investment incentives, access to deposits and proposed restrictions on raw-material exports. Yet the economics of these projects depend on more than the availability of mineral resources: investors also need reliable and affordable energy, transport infrastructure, stable policy and buyers for the finished products. Guinea’s refinery programme illustrates the scale of coordination required to move from exporting bauxite to building a domestic alumina industry. Delivering the planned capacity by 2030 will depend on whether processing projects and the electricity infrastructure needed to support them advance together.
