This partnership will create local jobs, establish resilient supply chains, and demonstrate how gravity energy storage can accelerate Africa’s transition from coal dependency to energy independence and security — all while delivering reliable, affordable power to communities that need it most.”
The initiative aligns closely with Eskom’s Just Energy Transition Partnership (JETP), which seeks to reduce dependence on coal while maintaining energy reliability, encouraging economic participation and supporting employment opportunities.
"Eskom is committed to reducing the environmental impact of its electricity generation activities and will continuously drive projects to support South Africa’s local and global emission reduction targets and transition responsibly. Eskom’s strategy is designed to position us as a resilient and competitive energy leader in a liberalised energy market."
"We will drive a just and inclusive energy transition that includes intensifying the repowering and repurposing of coal power stations and exploring clean coal technologies and solutions using technology as a strategic enabler to improve efficiencies and lower the cost of electricity. This partnership with Energy Vault and its innovative gravity storage technology will play a pivotal role in achieving our Just Energy Transition goals,” said Dan Marokane, group CEO, Eskom Holdings.
Southern Africa’s energy sector continues to evolve as governments and utilities pursue wider access to reliable and sustainable electricity. Electricity access across the SADC region has increased to 56% of the population, compared to 36% a decade earlier, reflecting expanding infrastructure investment and regional cooperation efforts.
Although coal still accounts for more than 80% of South Africa’s electricity generation, countries across the region are increasingly investing in renewable energy and storage technologies to diversify supply, strengthen grid resilience and improve long-term energy security. Utility-scale storage solutions are expected to become increasingly important in supporting renewable integration while also contributing to industrial growth, job creation and community development initiatives.

The launch of the Koruson 2 (K2) renewable energy cluster in South Africa’s Eastern Cape highlights Kumba Iron Ore’s continued focus on sustainable mining and cleaner energy solutions through its collaboration with Envusa Energy
Envusa Energy, a joint venture between Anglo American and EDF power solutions, is advancing the delivery of dependable and competitively priced renewable energy for South Africa’s energy-intensive sectors. The K2 cluster adds 520 MW of combined wind and solar capacity to the grid and forms part of the company’s wider target to develop between 3 GW and 5 GW of renewable energy by 2030.
For Kumba, the partnership is already generating measurable environmental, operational and financial gains.
“Our partnership with Envusa Energy allows Kumba to decarbonise our operations while strengthening the resilience and competitiveness of our business. It is a practical demonstration of how renewable energy can support both mining and South Africa’s economic future,” said Mpumi Zikalala, CEO Kumba Iron Ore.
At the Kolomela Mine in the Northern Cape, renewable energy now supplies around 72% of the site’s electricity demand, significantly lowering dependence on carbon-intensive grid power. Alongside emissions reductions, the mine also achieved financial savings, with approximately R600,000 (approx.US$30,000) saved during March alone.
Through the Sishen Iron Ore Company Community Development Trust (SIOC CDT), local communities are able to share in the value generated by both mining and renewable energy developments. The Trust maintains equity ownership in Kumba and is also set to hold a 10% stake in the Sishen solar project, supporting long-term investments in healthcare, education, infrastructure and livelihood programmes.
The K2 cluster also showcases how cooperation between industry, communities and government can help tackle South Africa’s energy constraints. Using an innovative wheeling model that enables renewable electricity to move across the national grid, the project is expected to strengthen energy security while supporting faster decarbonisation across major industries.
Aptech Africa electrifies 69 Sierra Leone schools with off-grid solar systems. (Image source: Aptech Africa)
Aptech Africa has completed the installation of standalone solar PV systems across 69 schools in Sierra Leone’s Western Area, covering both urban and rural districts including Central I & II, East I–III, West I–III, Koya Rural, Waterloo Rural and Mountain Rural
The company is also responsible for the ongoing maintenance of the systems.
Designed as hybrid off-grid installations, the systems generate solar electricity during daylight hours while simultaneously charging battery storage units. During the night or periods of cloudy weather, stored battery energy ensures a continuous electricity supply without reliance on the national grid. The systems provide dependable power for lighting, computers, Wi-Fi routers and printers within school administration blocks, enabling internet connectivity and digital operations in areas lacking grid infrastructure.
Installation teams secured the solar panels on reinforced roof-mounted rail systems, while batteries and inverters were placed within protected and ventilated enclosures inside principals’ offices or school administration buildings. Each installation operates independently, supplying power solely to local school equipment such as lights, laptops, routers and printers. Electrical cabling, fuses and breakers were integrated according to industry standards, while detailed commissioning reports and maintenance documentation were prepared for every site to support future servicing requirements.
The rollout faced several logistical and environmental challenges during implementation.
Accessing remote schools, particularly within Mountain Rural and other rural districts, proved difficult due to poor road infrastructure. Teams relied on four-wheel-drive vehicles and support from local communities to transport personnel and equipment to project sites. To improve efficiency, installations were grouped geographically, allowing crews to complete several nearby schools during a single deployment. In some locations, equipment was temporarily stored at regional hubs to reduce transport delays.
Seasonal weather conditions also created interruptions. Sierra Leone’s heavy rainy season occasionally delayed rooftop installations and electrical works. Project teams adapted schedules around weather forecasts and used temporary coverings where possible to continue work safely during short rain periods. Flexible planning and additional time allocations enabled all 69 systems to be completed successfully despite these constraints.
The project is expected to deliver significant educational, economic and social benefits across participating schools and communities.
Reliable electricity now supports extended study hours, improved administration and enhanced access to digital learning tools. With continuous power for internet routers and computers, schools can connect students and staff to online educational resources and modern learning platforms. The solar systems effectively introduce digital infrastructure into previously underserved schools and 'make education more flexible and accessible by powering the technology and infrastructure needed for digital learning'.
Consistent power also helps bridge connectivity gaps in rural education. Internet routers and communications equipment can now operate independently through off-grid solar supply, ensuring reliable access for teachers and students. Devices such as laptops, mobile phones and printers can also be charged directly through the systems. International community solar initiatives have similarly identified device charging as an essential service for improving educational access.
Administrative functions within schools have also improved. Teachers and principals can now operate office equipment including fans, projectors, printers and phones without disruptions caused by unreliable electricity or fuel shortages. Stable lighting additionally supports safer environments, improved record management and better operational efficiency.
The shift from diesel generators and inconsistent grid supply is also reducing operational costs. Lower spending on fuel and electricity allows schools to redirect funds toward educational materials, maintenance and staff development. International research has shown that solar PV systems can reduce school electricity costs by between 20% and 50%. In some instances, excess power generated by schools may also be shared with nearby buildings.
Environmental gains are another major outcome of the initiative. Replacing diesel and gasoline generators with renewable solar power significantly cuts emissions and local pollution levels. Similar school electrification projects supported by UNICEF in Eritrea demonstrated reductions in carbon emissions while improving access to digital education. Over the operational life of the systems, the Freetown installations are expected to avoid substantial volumes of CO₂ emissions.
Beyond the schools themselves, the project is anticipated to strengthen community confidence in public education. Access to functioning lights, internet services and digital technology can help improve student attendance and encourage enrolment. Previous UNICEF-supported programmes found that improved school infrastructure, including solar-powered facilities, contributed to higher attendance rates among girls in rural communities.
Overall, the initiative highlights how solar PV systems can transform educational infrastructure in off-grid regions. Schools gain “improved learning environments” alongside greater access to digital tools while supporting broader sustainability and climate objectives. The project also demonstrates the wider potential for renewable energy to support connected, technology-enabled education systems throughout Sierra Leone.
Newly inaugurated Graspan Solar PV plant adds 75MW to South Africa’s grid
Pele Green Energy and ENGIE South Africa have formally inaugurated the Graspan Solar PV facility in South Africa’s Northern Cape, celebrating a project that has already entered commercial operation and is currently supplying electricity to the national grid
The 75 MW solar project was developed under Bid Window Five of South Africa’s Renewable Energy Independent Power Producer Procurement Programme (REIPPPP). Combined with ENGIE’s Grootspruit Solar PV project in the Free State, the developments contribute a total of 150MW of renewable generation capacity to the country’s electricity network.
Having already commenced operations earlier this year, Graspan is actively feeding power into the grid, underlining the growing importance of utility-scale solar projects in addressing South Africa’s ongoing energy supply challenges while supporting longer-term grid resilience.
“These projects demonstrate what matters most in the current environment, which is execution,” commented Sanjeev Mungroo, managing director: renewables and batteries at ENGIE South Africa.
“Graspan is an operating asset contributing power to the grid today. That is critical as South Africa works to close its supply gap and build a more resilient electricity system.”
The project was developed in collaboration with local stakeholders, reinforcing the role of partnerships between the public and private sectors in expanding generation capacity through the REIPPPP framework.
Beyond increasing electricity supply, the solar facility reflects the broader transformation underway within South Africa’s energy sector. As renewable generation capacity continues to grow, projects such as Graspan are expected to contribute to a more balanced and diversified energy mix while reducing dependence on conventional power sources.
“Graspan shows what happens when partnerships are anchored in shared purpose. We’re not just delivering sustainable power into the grid – we’re driving economic activity, creating pathways for growth, and making sure communities feel the benefits of the energy transition. Today isn’t just about infrastructure. It’s a foundation for opportunity, dignity, and progress. Beyond the megawatts, impact means jobs, skills, and lasting value for local communities. For Pele Green Energy, this is moving from promise to performance – commercially sound and socially meaningful,” remarked Nicolas Lecomte, general manager, Pele Green Energy.
In addition to strengthening energy security, the project is anticipated to generate wider economic benefits through local procurement opportunities, workforce skills development and long-term investment initiatives aimed at surrounding communities.
For ENGIE South Africa, the commissioning of Graspan also forms part of a larger renewable energy pipeline that includes newly commissioned facilities, preferred bidder projects and participation in South Africa’s evolving electricity market.
“Graspan is part of a wider portfolio that reflects our long-term commitment to South Africa. The focus now is not only on adding capacity, but on ensuring that projects are delivered, integrated, and operated in a way that supports reliability, growth, and system resilience over time,” added Mungroo.

Work at Kamoa mine site (Image source: Ivanhoe Mines)
Canadian mining group Ivanhoe Mines has provided an update on its various power projects at its mine sites in the Democratic Republic of Congo (DRC)
Construction of Kamoa-Kakula’s on-site solar (PV) facility, with battery storage, is advancing “on schedule”, it reported in its Q1 statement, delivering a total baseload of 60 MW to the copper complex from early Q3 2026.
The solar facility is already the largest solar project with battery storage on the African continent, the mining group added.
Kamoa-Kakula is planning to increase total on-site solar power generation capacity, with battery storage, to 120 MW by the end of 2027.
A tender was awarded, and a power purchase agreement (PPA) signed in late April for an initial 30 MW expansion of the existing on-site solar facilities.
“A further 30-MW facility is currently being tendered and is expected to be awarded in the next month,” the Q1 report noted.
However, energy supply at the mining complex is also underpinned by thermal power plant.
This has resulted in efforts to secure fuel supplies in a volatile market amid tensions in the Middle East and the Strait of Hormuz.
“Preparations have been made across the group to secure on-site consumables in the event of continued global supply chain disruptions,” the company noted.
“This includes Kamoa-Kakula securing five months’ worth of diesel supply.”
However, the company added that the use of backup diesel generators could be be curtailed to rationalise diesel consumption.
Ivanhoe’s founder and co-chairman Robert Friedland said he remained bullish despite these challenges.
“Ivanhoe has a portfolio of tier-one mines powered by hydroelectric and solar power…built to withstand disruption,” he said.
“Our company is ideally positioned in this volatile environment, with exploding global demand for the copper, zinc, nickel and precious metals that we produce.”
At its Kipushi mine, the company is also currently tendering for a dedicated solar project with up to 200 megawatt hours (MWh) of battery energy storage.
This facility would provide 10 MW of baseload power, reducing reliance on the backup diesel generators that are used intermittently.
Located on a 70-hectare site near the mine, it is expected to be operational by the end of 2027.

At the heart of IVECO’s industrial operations is its Madrid facility, the only manufacturing site in Spain dedicated to heavy-duty industrial vehicles
The plant produces the company’s complete heavy truck range for international markets including Italy, Germany, Spain and Turkey.
Covering 374,000 m², the facility is built around a 1 km main assembly line and is capable of delivering close to 40,000 different vehicle configurations. With 267 core models and more than 2,800 customisation options available, production is designed around highly specific customer demands. On average, the same truck configuration is assembled just three times annually.
“Every truck we build is essentially a one-off, custom-made to meet specific requirements,” commented José Manuel Jaquotot, director of IVECO’s Madrid and Valladolid plants.
“Each vehicle has a unique identifier that allows us to track it from cab production in Valladolid to final assembly in Madrid, ensuring full traceability and quality.”
Manufacturing operations at the Madrid site rely on a flexible and tightly coordinated production system supported by automation and intelligent logistics. Automated Guided Vehicles (AGVs) transport units across the line, enabling takt times to shift according to the complexity of each build while maintaining uninterrupted workflow across the plant.
Truck cabs arrive from the IVECO Valladolid Plant already painted and welded before being fully equipped in Madrid with dashboards, seats, bunks and airbags. The dashboard assembly process alone includes more than 100 electrical checks and is managed on a separate production line because of its technical complexity.
A major milestone in the process is the integration of the chassis and cab, commonly referred to as the “marriage” stage. Once combined, the vehicle progresses through the fitting of exterior parts, wheel installation and a series of final inspections. These include leak detection, geometry calibration and full functional testing before completion.
The site’s workforce remains central to its operational success. More than 2,700 employees support production activities, bringing the expertise and adaptability required to manage constant product evolution. During 2025, the plant successfully introduced ten new launches.
Sustainability also plays a defining role across operations. The Madrid facility operates entirely on renewable electricity and, in 2025, recycled almost 90% of the water used throughout production processes. Alongside the Valladolid plant, the site forms part of Iveco Group’s broader sustainability strategy and participates in a solar self-consumption initiative with Edison Next Spain, a project expected to help prevent around 500 tons of CO₂ emissions every year.
IVECO’s focus on decarbonisation extends beyond the vehicles themselves to the manufacturing ecosystem behind them. The Madrid plant reflects this broader ambition by combining advanced production technologies, large-scale customisation and sustainable industrial practices in one integrated operation.

In the final webinar of its African Review-hosted 2023 campaign, Convergent Group explored its modern, eco-friendly concrete solutions for African projects
Such solutions – delivered to cut maintenance costs by eliminating hazardous silicate products – were showcased by company experts in the form of Jean-Claude Biard, SEO of Convergent Group SA; Mputu Schmidt, former CEO of Convergent Group SA and founder of Bondeko MB (exclusive distributor of Convergent Group in Africa); Carlos Garcia, technical and sales for ADI Group (Spanish distributor for Convergent Group); and Amritpal Singh Sura, external consultant for flooring treatments, former distributor of Convergent products in the Middle East.
“A number of projects we were doing in the Middle East required protection,” remarked Sura. “Longevity of protection requires a system which basically impregnates and becomes a densified surface as opposed to something which is topical and lifts off due to moisture migration. I found that being exposed to Convergent, it was important to stay focused on those systems in the Middle East. Jean-Claude, Mputu and I met several times in Dubai and there was emphasis on providing systems which were affordable and still ending up having a robust, lasting longevity of product. So you are not spending money all the time in order to maintain the finishes which you have already paid for.”
Over the course of the session, the participants guided the audience through the potential of cutting-edge lithium silicate technology for enhancing the protection of concrete surfaces, maximising cost-effectiveness and meeting sustainability targets.

Presenting on an African Review-hosted webinar, Martin Provencher, global industry principal for mining, metals and materials at AVEVA, explored the digital transformation of mining operations and its impact on sustainability.
“Sustainability is becoming a key aspect for mining operations,” remarked Provencher. “If we look at the latest EY research on the top ten business risks and opportunities for mining and metals globally in 2023, ESG remains at the top. Of course, most companies have environmental goals or are expected to reach a net zero emission by 2050, which is a pretty aggressive target. Many of them are targeting 30% reduction by 2030; seven years from now. So there is a lot of action that needs to take place quickly to get there. It is possible to get there, but we need to make sure we are doing this correctly.”
Fast becoming a huge part of ESG initiatives is fleet electrification where particular progress is being made in underground mines. While some countries are certainly more advanced than others here, Provencher noted that 40% of total emissions from the mining industry come from diesel trucks, making EVs a very attractive low-hanging fruit for companies to pursue.
There are, however, a number of challenges associated with bringing in electric vehicles which remains a barrier for introduction. One of the predominant reasons, is the limited range of EVs against diesel counterparts. To mitigate this, Provencher continued, data management is key and ensuring a strong grasp of real-time information coming in will show operators when machinery needs to be charged, allowing them to plan effectively for maximum efficiency on site.
Indeed, this is but a small advantage that digitalisation can bring to the mining industry as it grapples to meet ESG goals while achieving production targets. By getting a better grip of their data and using it to empower tools such as artificial intelligence, advanced analytics and machine learning, companies can achieve tangible benefits such as reduce downtime, enhance worker safety, cut operating costs and, of course, ensure compliance with environmental regulations and targets.
Through the course of the webinar, Provencher outlined this in more detail and explored AVEVA’s suite of cutting-edge software solutions, specifically designed to help mining companies make progress on their digitalisation journey and empower their operations.

Convergent, in association with African Review, has held a detailed webinar exploring the usage and effectiveness of lithium silicates and densifiers over traditional methods of concrete surface management which often struggle to meet the increasing challenges posed by concrete surface management.
Convergent experts including Mputu Schmidt, CEO of Convergent; Carlos Garcia, product manager end-user solutions, construction chemicals, Spain and Portugal for the RD Group; Matteo Mozzarelli, CEO of concrete Solutions Italia; and Jean-Claude Biard, global senior executive for the Convergent Group, presented across the session.
Together, they delved into the latest cost-effective application methods for long lasting finishing of concrete that can help reduce maintenance costs and avoid unexpected repair action. In addition, they examined the advancements in technologies that can sustain increased abrasion resistant stains and ensure gloss retention to the highest quality.
As part of the webinar, the representatives explored case studies including a case in DRC where a medical centre had been constructed with a low-quality concrete floor. The customer was considering completely replacing the floor but instead, Convergent put forward a special treatment with its 244+ Pentra-Sil lithium hardener, densifier and sealer. With this solution, Convergent can increase the hardness of a surface by up to 40% and therefore saved the customer significant recuperation costs over a complete replacement. Convergent were happy to report that the solution was perfect for the facility and the customer was pleased to avoid the extra construction work that would have been required for a complete replacement.

Weir has built the most extensive footprint of dewatering and slurry pumps across Africa’s mining landscape by supporting customers in reducing operational risk
This is achieved through a combination of advanced engineering, ongoing equipment refinement and a service network grounded in a fully compliant social licence to operate.
Marnus Koorts, General Manager – Original Equipment at Weir, explained that the company’s market position is shaped not only by the strength of its pump technologies, but by a comprehensive value chain approach that addresses risk throughout the lifecycle of mining operations.
“Mining is continuous and extremely capital intensive, so equipment must perform reliably and optimally,” said Koorts. “It is no surprise, therefore, that mines are risk averse when partnering with solution providers – they need to deal with partners they can trust.”
He notes that meeting the demanding uptime and performance requirements of modern mines calls for deep process knowledge and engineering capability, supported by a widespread service presence across the continent.
“Our customers’ first question is often about our references in a specific country or commodity,” he said.
“Thanks to our extensive footprint and vast experience, we’re almost always familiar with their operating environments – from the minerals being mined and processing conditions to the local regulatory landscape.”
Koorts points out that Weir’s large installed base provides a key advantage, generating valuable operational data across diverse commodities, climates and working conditions. This data is continuously fed back into product development and refinement.
“We are continuously releasing new variants of components based on feedback from the field,” commented Koorts.
“We are also digitally monitoring a large portion of our installed base, so it is not just physical site visits, but smart monitoring that allows us to improve performance, longevity and total cost of ownership.”
These insights enable Weir to deliver practical solutions, including equipment standardisation across multiple sites. In one recent West African gold project, the company recommended a minor design modification that allowed two operations to adopt a unified mill pump configuration.
Drawing on experience from the first site, Weir advised the engineering contractor on aligning motors and gearboxes, resulting in significant savings on spare parts inventory while lowering the risk of downtime.
“We have this capability due to our institutional knowledge of hundreds of projects and product applications,” remarked Kroots.
“This is a crucial part of the value that we bring as an OEM where we can collaborate with customers in applying the best solutions possible.”

AFC reaches financial close on the Poro Power Green Bond (Image source: Adobe Stock)
Africa Finance Corporation (AFC) has reached financial close and disbursed €43mn under the Poro Power Green Bond, to be used to fund construction of a 66 MW solar power plant in the northern Korhogo region in Cote d’Ivoire
Structured as a €65mn dual-currency facility in euros and CFA francs, it marks the first project finance green bond in Cote d’Ivoire and across the West African Economic and Monetary Union (WAEMU).
The solar power plant, developed by Poro Power, is expected to be operational in 2027 and will become the country’s largest solar plant.
The solar plant is expected to provide electricity to more than 100,000 households and avoid over 72,000 tons of CO2 emissions annually, contributing to greater energy access and the country’s target of increasing the share of renewables in the energy mix to 45% by 2030.
AFC acted as lead underwriter and co-arranger, helping to structure the innovative dual-currency green bond that creates what it called a ‘replicable model’ for mobilising African capital into bankable infrastructure.
It also called the transaction a milestone for Côte d’Ivoire’s capital markets and for African infrastructure more broadly.
Historically, long-term infrastructure financing in the country has depended heavily on international capital.
By contrast, the Poro Power Green Bond was African-led, structured, and fully funded by African institutions.
Samaila Zubairu, president and CEO of AFC, said the Poro Power Green Bond sets a new benchmark for sustainable infrastructure financing in Africa.
“This landmark transaction demonstrates the growing capacity of African institutions to mobilise domestic capital and expertise to deliver transformative infrastructure projects,” said said Zubairu.
“We are not only helping to close the infrastructure gap, but also creating scalable, homegrown financing models that can be replicated across the continent.”
The transaction builds on AFC’s track record in Côte d’Ivoire across the power and transport sectors.
In the energy sector, it includes the 44MW Singrobo-Ahouaty hydropower project, Côte d’Ivoire’s first private hydro independent power producer.
Its investments in the country also include the 1.5km Henri Konan Bédié Bridge, which has eased congestion by 30% since commissioning and improved mobility in Abidjan.
In 2024, AFC also supported the Ivorian government in awarding six road development contracts worth €691.6mn.
