Eskom has achieved a significant milestone in its ongoing efforts to stabilise South Africa's electricity supply, as the utility proudly announced that Unit 4 of the Medupi Power Station has been successfully returned to service.
The Medupi Power Station, located in Lephalale in South Africa's Limpopo province, holds thedistinction of being one of the world's largest dry-cooled, coal-fired power plant
The unit, which is now operational, adds an impressive 800MW to the national grid, further reinforcing the country's energy security.
The return of Unit 4 follows extensive repairs and a strategic approach that allowed it to come back online a remarkable eight months ahead of the original schedule.
This expedited process was made possible through the innovative use of a refurbished Generator Stator, which served as an alternative to waiting for a brand-new component, thereby avoiding costly delays.
Unit 4 had been out of service since 8 August 2021, after suffering substantial damage from the explosion of its original Generator Stator.
This critical failure prompted Eskom's engineering teams to formulate a Generation Operational Recovery Plan that focused on cost-effective and timely solutions.
By sourcing a used stator from the Netherlands and implementing strategic measures, Eskom overcame the long delivery times associated with new parts and successfully fast-tracked the unit's return to operational capacity.
With the reinstatement of Unit 4, all six units at the Medupi Power Station are now fully operational, poised to deliver a combined capacity of 4 800MW to the national grid as each unit reaches its full output in the coming weeks.

According to Eskom Group Chief Executive Dan Marokane, this corrective measure is integral to their overarching goal of achieving operational stability and adding a total of 2 500MW to the grid.
'Today's developments once again reflect the progress of our Generation Operational Recovery Plan, which is central to ensuring the long-term sustainability of the broader economy. This achievement moves us closer to consistently overcoming loadshedding, which is now largely behind us due to structural improvements in the generation fleet,' he said.
Eskom also extended its appreciation to the Medupi team, support staff, and all execution partners for their professionalism and commitment throughout this endeavour.
In particular, the successful and safe transportation of the 400-tonne Generator Stator, spanning approximately 1 000km by road from Richards Bay to the power station, was a notable highlight, achieved through the dedicated efforts of Eskom Rotek Industries.
Bheki Nxumalo, Eskom Group Executive for Generation, noted that the successful return of Unit 4 serves as a motivational achievement for their teams, reinforcing confidence in the reliability of Eskom's power supply moving forward.

Green hydrogen to power South Africa's future economy and job creation
Green hydrogen is set to play a defining role in South Africa's future energy mix, economic growth, and youth employment opportunities. This is according to Electricity and Energy Minister, Dr Kgosientsho Ramokgopa. Ramokgopa said South Africa is uniquely placed to lead the green hydrogen economy – an industry projected to exceed $300b (R60b) in global exports over the next 30 years. ALSO READ: Complaint lodged against City of Ekurhuleni for failing to supply electricity 'Green hydrogen is a big part of the South African growth story because it helps us to beneficiate our upstream endowments in the form of our platinum group metals (PGMs),' he said. 'Mining has the highest employment absorption capacity of any sector, so it's going to help get more people into employment.' South Africa is home to 80% of the world's PGMs and 40% of global platinum and palladium reserves – key ingredients in the hydrogen production process. Beyond its economic potential, green hydrogen offers solutions to decarbonising South Africa's hardest-to-abate sectors, particularly transport and energy. ALSO READ: CoE replaces old electricity meters with advanced pre-paid ones Ramokgopa noted that while Eskom is addressing electricity-related emissions, the country needs additional technology to reduce emissions in aviation and shipping – a gap green hydrogen can help close. 'It's going to help us transition and diversify our energy sources. With maturity, the cost of the technology will drop, making it a viable solution for South Africa,' he said. Aligning Africa's strategy The upcoming Africa Green Hydrogen Summit will focus on aligning African policy and investment to fully harness the continent's renewable potential. 'Africa can produce up to 60% of global renewable energy, but currently receives less than 1% of the total investment. Coordination is key,' Ramokgopa stressed. Jobs for the future The green hydrogen economy is expected to unlock thousands of jobs, particularly for South Africa's youth, across manufacturing, science, technology, and engineering sectors. Two PhD graduates, Dr Mphoma Matseke and Dr Victor Mashindi, currently working at Isondo Precious Metals, shared their experience with SAnews. ALSO READ: CoE updates locals on electricity meters 'Young people often don't know what green energy is. This platform can change that,' said Matseke. 'It feels amazing to be working at the cutting edge of technology. You leave university having studied science and end up in finance. Now, we can apply our knowledge to real problems, and that's exciting.' He encouraged young people to pursue Science, Technology, Engineering, and Mathematics fields, especially chemistry, to participate in what he called a 'bright future' powered by green energy.

Minister upholds green light for Eskom's new nuclear power station in Western Cape
Minister upholds green light for Eskom's new nuclear power station in Western Cape Minister of Forestry, Fisheries and the Environment, Dr Dion George, has upheld the 2017 decision to grant Eskom Environmental authorisation to construct and operate a new nuclear power station in Duynefontein, Western Cape. The decision was upheld after appeals were made by various environmental organisations. 'In considering these appeals, I have carefully reviewed the Environmental Impact Assessment Report (EIAr), as well as the independent peer review conducted in respect of the project. 'In the end, my decision was made in respect of the principles of the National Environmental Management Act, 1998 (Act No. 107 of 1998), and with full appreciation of the environmental, social and economic considerations involved,' the minister said on Friday. The original decision to grant the environmental authorisation was made in October 2017. Various appellants challenged the decision, submitting appeals that ranged from comprehensive and detailed submissions to shorter, individual objections. This week, the minister has decided, in terms of section 43(6) of NEMA, to dismiss the appeals, and confirm the decision to grant the environmental authorisation to Eskom. Appeals dismissed, but more approvals still needed for nuclear build The minister's decision to uphold the environmental authorisation does not automatically grant Eskom permission to begin with the construction or operation of the nuclear power station. The entity is still required to obtain several additional statutory authorisations before proceeding in accordance with section 24(7) of NEMA. The authorisations include: A nuclear installation licence from the National Nuclear Regulator (NNR); Approval from the National Energy Regulator of South Africa (NERSA); Water use licences from the Department of Water and Sanitation, and Any other relevant approvals, including those from the Minister of Mineral and Petroleum Resources. 'As per section 24(7) of NEMA, the granting of an Environmental Authorisation does not exempt an applicant from complying with any other applicable legal requirements or obtaining permits from other competent authorities,' George said. Dion says that the protection and preservation of South Africa's environment is a non-negotiable. 'The Department of Forestry, Fisheries and the Environment supports South Africa's transition to a cleaner, more sustainable energy future where inclusive growth, job creation and poverty reduction are central,' he said. – Breaking news at your fingertips… Follow Caxton Network News on Facebook and join our WhatsApp channel.
