Three refineries, one pipeline
On June 13, 2026, Guinea launched construction of the Chalco alumina refinery on the Lisso-Demougala site, located approximately 40 kilometres from Boffa. The ceremony was co-chaired by General Amara Camara, Secretary General of the Presidency, and Djiba Diakité, Chairman of the Strategic Committee of Simandou, in the presence of government representatives, industrial partners, and local communities. The project represents an estimated investment of one billion dollars and plans for a production capacity of 1.2 million tonnes of alumina per year. This unit adds to the refinery projects led by SPIC and the Winning Consortium in Dobali. The three projects now active in Guinea’s refinery pipeline carry a combined planned capacity of 4.8 million tonnes of alumina annually: SPIC at 1.2 million tonnes targeting completion by late 2027 and commercial production by December 2028; the Winning Consortium Alumina Guinea refinery planned for 2028 at 1.2 million tonnes per year; and the Chalco project at 1.2 million tonnes per year, with construction launched June 13 pending Chalco shareholder approval expected by August 10, 2026. Guinea’s only operating alumina refinery remains the RUSAL-operated Friguia facility at 600,000 tonnes per year. The country has not built a refinery since the colonial period. It is now attempting to build three simultaneously.
The contractual architecture that makes the pipeline credible
The government’s enforcement mechanism gives the pipeline credibility that previous refinery commitments in Guinea lacked. SPIC faces a strict deadline, with the Guinean government reserving the right to withdraw the mining concession if commercial production is not achieved by December 2028. The government’s resolve was starkly demonstrated in August 2025, when the bauxite mining concession of Emirates Global Aluminium and its subsidiary Guinea Alumina Corporation was revoked. This action followed GAC’s failure to adhere to its commitment to construct a 1 million tonnes per year alumina refinery, despite signing a term sheet in June 2024 and receiving an extension until September 2026. The GAC revocation is the enforcement precedent that makes SPIC’s December 2028 deadline credible and gives Chalco’s shareholder approval process a specific political risk dimension: if shareholder approval is delayed beyond the August 2026 deadline, the Guinean government may revisit the terms of the concession arrangement. Chalco’s board intends to seek shareholder approval through a general meeting, with detailed project disclosures expected to be circulated to investors by August 10, 2026. Shareholder approval uncertainty could surface investor concerns about capital allocation or Guinea-specific political risk. The concession-linked conditionality that the government is applying uniformly across its refinery pipeline is the operational expression of resource nationalism by contract rather than by decree, a model that this series has documented as structurally more durable than either voluntary commitment or state intervention alone.
The energy arithmetic that the pipeline cannot yet solve
The combined energy requirement of the three refineries is where the pipeline’s most significant structural constraint sits. Alumina refining through the Bayer process is energy-intensive: a 1.2 million tonne refinery requires between 200 and 300 megawatts of reliable electricity supply under continuous operation. Three such refineries would require between 600 and 900 megawatts of dedicated industrial power. The SPIC refinery, under construction now, will be the country’s largest, capable of processing 1.2 million tonnes of alumina each year and powered by a 250 megawatt integrated plant. SPIC has solved its own energy problem by internalising it: the 250 megawatt captive plant, with 100 megawatts earmarked for Guinea’s national grid, makes SPIC energy-independent while contributing to national capacity. Chalco and the Winning Consortium face the same requirement. Guinea’s 450 megawatt Souapiti Hydropower Plant and the 240 megawatt Kaleta facility have significantly expanded national generation capacity, together supplying over 80% of Guinea’s electricity demand. That 690 megawatt combined hydropower capacity is not available in full to industrial users: it supplies residential and commercial demand across Conakry and 11 prefectures, supports grid exports to Senegal, The Gambia, and Guinea-Bissau under the OMVG transmission framework, and must maintain reserve capacity for the dry season when river levels reduce output. Despite both dams being operational, Guinea remains in electricity deficit. In 2024, Guinea signed an agreement to import 124 megawatts from Senegal. A country that imports power from its neighbour to meet current demand cannot supply three energy-intensive industrial refineries from its existing grid.
The gap between pipeline and delivery
The Simandou 2040 programme has identified a 10 gigawatt hydropower target as the energy architecture for Guinea’s industrialisation. Planned expansions include the 300 megawatt Amaria hydropower project and the 294 megawatt Koukoutamba hydropower plant being developed under the Senegal River Basin Development Authority, along with three micro-hydro plants totalling 30 megawatts by 2027. These projects extend Guinea’s generation capacity pipeline, but their commissioning timelines run beyond the December 2028 refinery production deadlines. SPIC’s integrated 250 megawatt captive plant is the model that resolves this sequencing problem for a single project. It does not resolve it for the pipeline as a whole. If Chalco and the Winning Consortium are required to bring their own captive power generation as a condition of their concession arrangements, the combined investment in refinery-associated power infrastructure across the three projects would approach 700 to 800 megawatts of new generation capacity, broadly equivalent to a second Souapiti complex, financed and operated by industrial actors rather than the state. That outcome would meaningfully expand Guinea’s installed generation base while resolving each project’s energy constraint individually. It would also place the control of a significant share of Guinea’s new power infrastructure in the hands of Chinese industrial operators, adding a sovereignty dimension to the energy architecture that the IMF mission currently working through Simandou 2040 conditionality will need to address. The VINCI solar grid and EBID infrastructure financing documented in this series represent Guinea’s attempt to build nationally owned energy capacity in parallel. Whether that parallel track keeps pace with the industrial demand the refinery pipeline is generating is the energy governance question that the 4.8 million tonne alumina ambition has now placed directly on the table.
