On May 20, 2026, at the Africa Energy Technology Conference in Accra, Julius Debrah announced that the Ghanaian government is in the process of signing a bilateral agreement for the construction of a 1,000 MW nuclear power plant and is simultaneously engaging partners for the deployment of small modular reactors. Technical assessments for site selection are reportedly in their final stages, with a formal roadmap expected in the coming months. The announcement positions nuclear energy as a cornerstone of President Mahama’s energy strategy, framed as a generational investment in affordable, reliable and clean electricity for the manufacturing and mining sectors.
The timing is not incidental. In April 2026, a fire at the GRIDCo substation near the Akosombo hydroelectric dam knocked out approximately 960 MW of transmission capacity, roughly 25% of Ghana’s peak demand of 3,500 to 4,000 MW. The incident triggered widespread load shedding across the Ashanti, Central and Greater Accra corridors. Ghana temporarily suspended electricity exports to Togo, Benin, Burkina Faso and other West African neighbours to stabilize its own grid. When the Mahama administration took office in December 2024, the power sector was already facing a generation deficit exceeding 700 MW. The Akosombo fire did not create the structural problem. It exposed its depth.
Ghana’s installed generation capacity exceeds 5,000 MW. But installed capacity and reliable supply are not the same thing. The grid remains heavily dependent on a small number of high-capacity nodes. The Akosombo and Kpong hydroelectric plants, which have anchored Ghana’s baseload for six decades, currently supply approximately 32% of electricity, a share projected to decline to about 25% beyond 2025 as water levels drop due to climate variability. The rest of the mix is overwhelmingly thermal, dependent on imported gas or liquid fuels. There is no second baseload source of comparable scale or reliability in the current system. That is the structural gap nuclear is being positioned to fill.
The institutional groundwork is more advanced than in any other newcomer African country. Nuclear Power Ghana, established in 2018 as the designated owner and operator of the first plant, has been running for eight years. In September 2023, NPG selected Nsuban in the Western Region as the preferred site, with Obotan in the Central Region as backup. In February 2025, Ghana hosted its first IAEA Site and External Events Design Review mission, which confirmed that the site selection process and management systems were in line with IAEA safety standards. The Nuclear Regulatory Authority of Ghana completed its first Integrated Regulatory Review Services mission in 2024 and is building competencies for overseeing a nuclear programme commensurate with each phase of the project. Ghana is in Phase 2 of the IAEA’s Milestones Approach, alongside Kenya and Nigeria, meaning it has completed pre-feasibility studies and made a firm decision to use nuclear technology for electricity production. Only Egypt is more advanced on the continent, at Phase 3.
The vendor landscape reflects the geopolitical competition that now surrounds nuclear exports to Africa. In August 2024, NPG and Regnum Technology Group, a US-based developer partnered with NuScale Power, signed a commercial agreement to deploy a single NuScale VOYGR-12 SMR plant at the US-Africa Nuclear Energy Summit in Nairobi. NuScale’s technology is the only SMR to have received design certification from the US Nuclear Regulatory Commission. Ghana also hosts the NuScale Energy Exploration Center at the Ghana Atomic Energy Commission, which includes Africa’s first SMR control room simulator. Separately, NPG has identified China National Nuclear Corporation’s HPR1000 as a candidate for the large light-water reactor track. Other potential vendors include France’s EDF, South Korea’s KEPCO/KHNP, and Russia’s Rosatom, with which Ghana signed an intergovernmental agreement. NPG’s executive director has stated that the final selection could involve one vendor or two, depending on the financial model and technical specifics, with preference for a build-own-operate-transfer arrangement with local equity participation. Parliamentary approval will be required given the scale of project funding.
The financing question is the central constraint. Energy Intelligence has described Ghana as “poised, technologically and operationally, to be the first nuclear state” on the continent after South Africa and Egypt, while noting that the country “lacks the financial resources to fully support a newbuild project without substantial support from the vendor nation.” Egypt’s El-Dabaa project, the continent’s only active large-scale nuclear construction, is financed primarily through a government-to-government loan from Russia. Ghana does not have an equivalent bilateral financing framework in place. The cost of a 1,000 MW nuclear plant is typically in the range of $5 to $10 billion or more, depending on technology, site conditions and financing terms. For a country whose power sector already carries significant financial strain, the structure of the financing matters as much as the choice of technology.
The regional dimension adds a layer of strategic logic that goes beyond Ghana’s own grid. The West African Power Pool achieved full-grid synchronization for four hours in November 2025, connecting all member states within a single network. Permanent synchronization is targeted for mid-2026. If it holds, a regional nuclear project model becomes conceivable, in which a single large reactor in Ghana could supply multiple countries via interconnectors such as the Ghana-Burkina Faso line. For vendors, a regional off-taker pool improves bankability and allows design standardization, which is critical for SMR economics. For Ghana, it transforms a national infrastructure investment into a regional platform.
The broader African nuclear pipeline is more active than it has ever been. Egypt’s four-unit El-Dabaa plant, using Russian VVER-1200 reactors, is expected to begin operations by 2028. Kenya had planned to begin construction of a 1,000 MW plant in 2027, but the dissolution of the Nuclear Power and Energy Agency in January 2025 has effectively put its programme on hold. Nigeria has resumed preparations after shelving its earlier Geregu project. The IAEA projects that nuclear capacity in Africa could increase tenfold by 2050 in a high-case scenario, requiring over $100 billion of investment. The World Nuclear Association forecasts that Ghana and Nigeria will each have 1 GW in operation by 2038. In total, 22 African countries are currently exploring civil nuclear programmes, though only Ghana, Kenya and Nigeria have progressed to the stage of active preparation.
The question is sequencing. Ghana’s nuclear roadmap originally called for construction to start by 2024 and commissioning by 2030. Both dates have slipped. The current target is construction around 2027 and first operations by 2034. Every nuclear newcomer programme on the continent has experienced similar delays. The gap between announcement and construction is where most projects stall, caught between vendor selection, financing closure, regulatory maturation and public engagement. Ghana has advanced further than any other West African country on all four fronts. But the distance from where it is today to a functioning nuclear plant is still measured in years, not months.
What the Akosombo fire has done is remove any ambiguity about the urgency. Ghana’s baseload problem is no longer a medium-term planning issue. It is a present-day constraint on industrial output and regional electricity trade. Nuclear is not the only answer. But it is the only option being considered at the scale and duration that a baseload replacement requires. The question is whether the financing and vendor decisions can be locked in fast enough to match the pace at which the existing system is losing capacity.
