In open-pit mining, the largest source of energy use and greenhouse gas emissions is often hidden in plain sight: haulage.

Heavy-duty trucks used for loading and hauling can account for between 41% and 66% of total energy consumption, and up to 54% of GHG emissions in operations such as iron, bauxite and coal mining.

As pressure mounts to reduce environmental impact, a novel fuel-efficiency model is challenging traditional dispatch systems that prioritised production alone. By optimising fuel consumption and aligning four interdependent goals, the approach aims to lower emissions while strengthening economic performance.

If you have ever questioned a high electricity bill, consider the industrial reality where a single Continuous Miner can consume more than 91,000kWh every month.

At that scale, electricity is not just an overhead, it is a defining operating risk.

At the Khairaha Underground mine in India, rising power costs prompted a detailed energy audit that went far beyond standard practice.

The focus was on the electrical systems of heavy underground machinery, using advanced diagnostic techniques to expose inefficiencies that often remain hidden but carry serious financial consequences.

The lessons are highly relevant for African mining and energy stakeholders grappling with rising tariffs, constrained supply and decarbonisation pressures.

NERSA ZA has published the outcomes of its workshop with municipalities and private distributors on tariff applications for the 2026/27 financial year.

The discussions were framed by the North Gauteng High Court judgment of 4 December, which introduces new structural deadlines for Eskom Hld SOC Ltd tariff approvals and for the submission and approval of municipal tariffs.

While participants acknowledged that the court-mandated timelines place severe pressure on both municipalities and the regulator, there was agreement to comply.

This is to ensure NERSA can still conduct a meaningful public participation process, as required under the Promotion of Administrative Justice Act, ahead of the 5 May 2026 deadline for tariff approval.

The IEA’s newly released Coal 2025 report shows coal facing growing competition from renewables, natural gas and nuclear power, even as global demand reaches a record 8.85 billion tonnes in 2025.

While demand rises modestly next year, the agency expects it to plateau before edging down towards 2030. China remains central to coal’s outlook, accounting for more than half of global use, even as it rolls out renewable capacity at unprecedented scale.

Africa’s coal consumption is forecast to tick up slightly in 2025, largely due to capacity improvements in South Africa. The report underscores how policy, weather and electricity demand growth will shape coal’s future.

The second 60MW phase of the 120MW Mmadinare Solar Cluster has been commercialised, bringing Botswana’s largest renewable energy project closer to full operation.

This milestone strengthens the country’s push to scale up domestic power generation, cut carbon emissions, and unlock new economic activity in the Mmadinare community.

Once fully optimised, the project is expected to generate around 280GWh of clean electricity annually and avoid approximately 380,000 tonnes of CO₂ emissions.

LONGi has shared the global field performance results for its Back Contact (BC) technology platform and the Hi-MO 9 module, following an extensive testing programme conducted with customers, independent bodies and its own sites worldwide.

The programme assessed long-term power generation performance across a range of regions, including China, Europe, the Middle East, Asia-Pacific and Latin America.

Testing covered everything from temperate continental climates to tropical, arid and high-humidity coastal environments, offering rare comparative insight into real-world module behaviour outside controlled laboratories.

The global dataset points to a high level of stability, consistency and economic performance, reinforcing the Hi-MO 9’s value proposition for developers operating in challenging or varied conditions.

LONGi’s London launch on 26 November signals a decisive strategic shift that the global energy sector should not overlook.

For the first time, Vice President Dennis She set out the company’s integrated Solar-Storage-Hydrogen strategy, positioning storage as the stabiliser in a power system where global electricity demand is set to double by 2050.

The newly presented Stability Triangle framework places solar as the energy creator, storage as the system stabiliser, and hydrogen as the balancing vector.

With world-leading PV and hydrogen technologies already in hand, LONGi’s expansion into storage now closes the loop on its end-to-end value chain.

Rosatom’s Experimental Design Bureau of Mechanical Engineering (OKBM Afrikantov) has achieved a significant milestone with regulatory approval to manufacture components for the RITM-200 reactor plant using 3D printing technology. This approval represents the first certification of additive manufacturing for reactor-plant components in Russia’s nuclear sector.

The development follows the successful qualification of a 3D-printed terminal box used in nuclear power plant pumping equipment. Its approval signals a major shift in how critical nuclear components may be produced in future, potentially reducing lead times, lowering costs and increasing design flexibility.

The RITM-200 reactor, used in marine and floating nuclear applications, is built on more than 60 years of operational experience with nuclear-powered vessels, combined with modern 3D design tools and high-end simulation and supercomputer analysis.

As global interest in small modular and floating nuclear technologies grows, this breakthrough could accelerate deployment timelines and influence future manufacturing standards.
