COMMENT
The turning of the year 2 025! So, we end one year and start the next. There is little doubt that 2025 was an interesting year. Of course, it was tough – but it also presented one or two sparks of hope, I think. If we leave sport aside for a moment, the G20 was a success – and although there are certainly appropriate but cynical views about why we suddenly saw folk working to repair, maintain and ‘make nice’ Johannesburg, as the host city – the impact was positive. We also saw the Medium-Term Budget Policy Statement provide a few flickers of positive sentiment. And we saw what was some quite extraordinary washing of dirty linen in public via various commissions and enquiries – in a way which suggested it may be very hard to hide what everyone can see happening. What can we take away from all of this? Well, if there is a will there is a way. If there is political will and the money can be found (don’t think too much about this comment…) things can be done. And they can be done well. It also seems that folk in general have had it with enquiries that seem to present pretty obvious outcomes, and nothing is done following the fact. It seems that regular citizens will no longer tolerate that. The last general observation is that we may be seeing a meeting of minds at the highest levels of political leadership – some indication that the Government of National Unity may be developing a more constructive approach to the way the country is managed – and that is having an impact. Let’s wait and see … This was also an interesting year for me personally, as I found myself having to step

Subsea cables power the data centre-driven digital economy
The internet as we know it would not exist without the vast, largely invisible network of subsea cables lying deep beneath the ocean’s surface. Stretching across thousands of kilometres, these cables are the arteries of the global digital economy, carrying over 95% of the world’s data traic. Teraco here looks at increasing investments in this infrastructure to serve escalating data demand, globally.
Left: Subsea cables connect countries – and they connect large ecosystem data centres which have become critical points of presence for subsea cable operators. Right: Internet traffic is doubling every two years, demanding faster and more dense connections.
R esearch by TeleGeography indicates that, in 2025, there were 570 in-service subsea cable systems worldwide, with an additional 81 systems planned, a record high within the past two decades. This explosive growth is being driven by soaring global data demand, the rapid rise of artificial intelligence (AI), and the need for more resilient, high-capacity connectivity. Surge in investment According to TeleGeography’s Transport Networks Research Service, investment in subsea cables has accelerated at an unprecedented pace. Over the past nine years, an average of $2 billion has been spent annually on new cable construction. However, between 2025 and 2027, spending of more than $13 billion in additional subsea cables is expected. Since the early 2000s, when state-backed enterprises and telecom consortiums dominated, the investment landscape has changed. Today, technology giants like Amazon, Google, Meta, and Microso¤ are leading the way, building private subsea cables to interconnect their global data centre networks directly and deliver low-latency, high-capacity services to users worldwide. Several factors are driving this surge in subsea infrastructure investment: exponential data growth, content provider dominance, network resilience, and the ageing of existing subsea cable infrastructure. Internet tra§ic is doubling every two years, demanding faster and more dense connections. Tech giants now account for most of the subsea bandwidth usage, prompting them to build their own cables instead of leasing capacity. Enterprises increasingly require mesh networks that span multiple cables to ensure business continuity during outages. Some legacy cables are nearing the end of their lifespan, requiring next-generation systems with significantly higher capacity and lower unit costs.
The future of connectivity Trends shaping the future of subsea connectivity include: the rise of interconnections within data centres, geographic diversity and network resilience, technological advances, sustainability and climate resilience, and security and maintenance. Subsea cables connect countries – and they connect data centres. With AI workloads, streaming platforms, and cloud computing demanding massive throughput, large ecosystem data centres have become critical points of presence for subsea cable operators. The closer a business is to these hubs, the lower its latency, and the faster its access to global markets. Many cables are being built along new routes to connect previously underserved regions, particularly in Africa, Southeast Asia, and South America. By diversifying routes, operators reduce the risk of single points of failure and enhance disaster recovery capabilities. New cable technologies are enabling faster data transfer speeds, increased capacity, and greater durability. Improved fibre designs, advanced materials, and innovative deployment methods are allowing operators to manage greater demands and navigate challenging seabed conditions. Climate change has created new risks, including stronger ocean currents, severe storms, and increased seabed instability. In response, cable operators are burying cables deeper, using reinforced designs, and selecting routes more carefully to strike a balance between environmental impact and connectivity needs. With an average of 150 to 200 cable faults reported globally every year, proactive monitoring and maintenance are essential. Furthermore, national security concerns have prompted increased investment in physical and cybersecurity measures to protect the world’s digital backbone.

Africa’s role in the global subsea ecosystem Africa is seeing major investments in new subsea cable systems on both the east and west coasts. With new cables landing in the region, including 2Africa and Google’s Equiano, local businesses have access to unprecedented levels of bandwidth and interconnection. A number of cables, such as ACE, EASSy, METISS, SAT3/SAFE, Seacom, and WACS also enable improved connectivity in the region. Within this ecosystem, Teraco’s network-dense data centre infrastructure has become a cornerstone of Africa’s internet connectivity. Its facilities host over 250 network providers, including all major subsea cable operators traversing the continent. This creates an extensive interconnected environment where clients can switch instantly between network providers during cable outages, access alternative routes across east and west coasts to maintain uptime, and cross-connect directly with carriers, ISPs, and cloud platforms at scale.
NAPAfrica, one of the top seven global Internet Exchange Points (IXPs), operates within the Teraco ecosystem, enabling networks, ISPs, and content providers to exchange tra§ic directly. During subsea cable outages, NAPAfrica has consistently managed surges in tra§ic volumes, maintaining critical services and supporting seamless internet access for millions. Building a more resilient future Subsea cables form the backbone of our connected world, but they are only as powerful as the infrastructure they link to. Teraco is enabling enterprises, service providers, and hyperscalers to use this global network, providing resilient interconnection, scalable capacity, and a data centre ecosystem purpose-built for the digital age. As investment in subsea cables continues to rise, the convergence of data centres, subsea infrastructure, and edge connectivity will define the next chapter of global digital transformation.

Developing smarter technologies for water management
Adroit Technologies, a leader in industrial automation and digital transformation solutions and well experienced in working with water utilities, is advancing its research and development into an AI-powered Water Management Platform, to help address one of South Africa’s most urgent infrastructure challenges: non- revenue water losses. The R&D programme is exploring the potential to develop a first if its kind, AI-driven ‘pseudo-metering’ capability, one that can infer consumption and pressure data in areas where physical meters are not installed. “We have proven the initial concept and have now secured the support of government and other industry leaders to develop this AI-driven platform,” says Frits Kok, Co-CEO at Adroit Technologies. With nearly 40% of the country’s treated water lost to leaks, the¤, and ageing infrastructure, Adroit Technologies is looking at new ways to enhance intelligent, data-driven water management. Using advanced machine learning (ML) and neural network algorithms, the research platform can analyse existing telemetry and SCADA data to detect leaks, forecast demand, and infer flow rates in areas without sensors, potentially opening a route to more e§icient, transparent municipal water systems. “Smarter, data-driven solutions can help address South Africa’s water infrastructure challenges,” says Kok. “Our current R&D is focused on developing next-generation AI capabilities that will, in time, complement our existing water management technologies, which are already helping utilities reduce water losses and make informed operational decisions.” A national challenge Urban growth, vandalism, and limited monitoring capacity have placed severe strain on South Africa’s water systems. In many municipalities, leaks and pump failures are discovered only a¤er outages occur. Through its ongoing research, Adroit Technologies aims to integrate new AI tools with existing SCADA and telemetry systems
to deliver predictive analytics, real-time alerts, and actionable insights, helping engineers identify hidden losses and optimise operations before crises arise. The AI-driven pseudo-metering can infer consumption and pressure data where physical meters are missing or damaged. It has the potential to help under-resourced municipalities monitor conditions across water networks that were previously ‘data blind’. Adroit Technologies’ current research is focused on developing a scalable, national-level AI framework that leverages forecasting, anomaly detection, and digital twin modelling to enhance decision-making and support more e§icient water use. A hybrid neural network architecture (CNN-LSTM) and self-healing data middleware are being designed to operate e§ectively even with incomplete or delayed data, a common challenge across South Africa’s municipalities. “This research is about enabling resilience,” says Hugo Pienaar, Director of Digital Services at Adroit Technologies. “By combining AI with decades of SCADA expertise, we are helping municipalities envision how to predict issues before they happen and manage scarce water resources more e§iciently.” Adroit Technologies is exploring new ways to enhance intelligent, data- driven water management.

cable sizing, and creates the necessary documentation – all in one workflow. This eliminates the need for time-consuming manual calculations. With cloud technology, users can collaborate on projects from anywhere and always have access to the latest planning data. This development strengthens Siemens’ position as a technology leader in digital control panel design and opens up new possibilities for more e§icient engineering. “Electrical Designer from Siemens represents a quantum leap in electrical planning,” said Andreas Matthé, CEO Electrical Products at Siemens Smart Infrastructure. “It’s the world’s first browser- based solution to combine standards compliance, short-circuit analysis, and automatic dimensioning. It cuts planning time in half, eliminates errors, and provides specific standards knowledge. For us, this is the future of engineering.” At a glance - Electrical Designer o§ers end-to-end verification of short-circuit re- sistance in accordance with IEC standards, from the individual load to the feed point in the machine. - Complete machine design replaces individual calculations: If the so¤ware knows the loads for the machine, the tool automatical- ly selects suitable switchgear, controls, and network components and generates parts lists and complete documentation. - Electrical Designer automatically checks the requirements defined in the relevant standards (currently IEC 60204-1). - As a completely browser-based solution, there is no need for instal- lations and updates. Electrical Designer o§ers device-independent access at any time using the latest so¤ware, enables easy project transfer, and helps companies cut planning times. This increases scalability and supports investment protection. - The so¤ware’s flexible calculation logic allows planners to simulate di§erent short-circuit scenarios to adapt the electrical system opti- mally to local grid conditions. Electrical Designer is available free of charge to all TIA Selection Tool Cloud users.
Siemens has expanded the TIA Selection Tool Cloud with the new ‘Electrical Designer’ feature for electrical planning. This smart so¤ware is the first and only in the IEC market (the market where International Electrotechnical Commission standards apply) that includes basic electrical knowledge and standards expertise, eliminating the need for time-consuming research and complex manual work. Electrical Designer simplifies main circuit design by automatically selecting components, verifying short-circuits, sizing cables, and creating all the necessary documentation in one easy process. Electrical planners o¤en encounter limitations when designing electrical equipment for machines. An overabundance of caution and time pressure can result in old plans being adopted, with outdated or ine§icient concepts included. Additionally, mechanical design data and documents o¤en cannot be processed seamlessly in the electrical design and have to be reworked. This presents potential for savings and quality improvement. Siemens’ Electrical Designer, part of the TIA Selection Tool Cloud, helps the design engineer save time and avoid errors, so improving planning quality. Tasks that used to take hours can be done in less than half the time: the Electrical Designer automatically selects the components for the complete main circuit in accordance with IEC 60204-1, provides short-circuit verification, allows for precise IIoT controller for field or control cabinet Ifm describes its IIoT controller as a powerful, communicative and flexible PLC solution for use in machine and plant digitalisation.

Global collaboration supporting the AI boom
Tokyo Stock Exchange listed Hitachi, Ltd and Hitachi Energy, a global leader in electrification, recently announced support for the 800 volt direct current (Vdc) power architecture that Nvidia is working towards [1] by developing a cleaner, more e§icient way to power the next-generation of artificial intelligence (AI) infrastructure. At this level, the power architecture paves the way for more energy-e§icient ‘AI factories’ at a global scale. Modern AI workloads are pushing data centres beyond the limits of traditional power architectures, which were designed for smaller compute loads. Hitachi Energy’s advanced grid- to-rack architecture supports the 800 Vdc rack design and streamlines the flow of electricity from the grid to servers. It o§ers a simpler, more e§icient, and more sustainable power system built for modern data centres, one that cuts energy waste, reduces cooling needs, and accelerates the deployment of hyperscale AI facilities. “As the energy arm of the Hitachi Group, Hitachi Energy brings over a century of expertise in grid technologies and power electronics to this collaboration,” said Jun Taniguchi, Senior Vice President and Executive O§icer, CEO of Strategic SIB Business Unit, Hitachi, Ltd. “Through our wider focus on the data centre industry, the Hitachi Group’s combined expertise enables clean and sustainable development of the AI factories of the future.” It is forecast that up to 125 gigawatts (GW) of AI data centre
capacity could be developed globally between 2025 and 2030 [2] , comparable to Spain’s total installed generation capacity [3] . Meeting this demand requires unprecedented investment and advances in computing as well as in energy infrastructure. As a global market leader in transformers, high-voltage technology, digitalised grids, and service, Hitachi Energy is investing $9 billion globally, the largest investment in the industry, to expand manufacturing, R&D, engineering, and partnerships. This includes a historic $1 billion investment to advance the production of critical grid solutions in the US. The investments will be key to meeting energy needs, including the energy needs of AI data centres, and supporting a robust, future-ready electric grid. Hitachi and Hitachi Energy support the 800 Vdc power architecture Nvidia is working towards for the next generation of AI infrastructure.

SAREGS points to a pipeline of 220 GW in renewables projects Leigh Darroll, Editor, Electricity + Control
The results of the latest South African Renewable Energy Grid Survey (SAREGS) point to a strong and growing pipeline of development projects in the renewable energy sector, including solar, wind, battery storage and hybrid projects, plus support for ancillary services.
T he results of the 2025 survey were presented by the NTCSA on 27 October 2025 in a webinar co-hosted by the NTCSA (National Transmission Company South Africa), SAPVIA (the South African Photovoltaic Industry Association) and SAWEA (the South African Wind Energy Association). These parties work together to conduct the survey annually with members of the respective industry bodies playing an essential part in providing the information on where new projects are planned, using which technologies, and over what timeframe, which goes into determining grid
Insights provided by the survey can help the NTCSA and Eskom prioritise transmission upgrades in high-demand zones, aligning investment with confirmed project pipelines.
Highlights of the survey Planned projects indicate 60 to 70+ gigawatts (GW) of renewable energy development in the near-term. Classified as Type A projects, these are projects with all plans in place, EIAs (Environmental Impact Assessments)) approved, and ready to roll out, pending financial close. A further 30 to 45 GW is indicated in mid-term projects, that is, to 2035. These are Type B projects, gearing up to move forward through the required approval and financing processes. And over the longer term, another 41 to 103 GW of potential renewable energy development is under consideration.
transmission requirements over the near- to longer-term. For the 2025 surv3ey more inputs were received, from 673 respondents, significantly up from 483 respondents in the previous year. Presenting the results of the survey, Ronald Marais, Senior Manager for Strategic Grid Planning at the NTCSA, thanked all the contributors for their input and noted that the SAREGS is an important element feeding into the Transmission Development Plan which is reviewed and updated usually annually by the NTCSA. The results of the SAREGS are shared on the NTCSA website and there is an interactive map where visitors can explore different interest areas.
Together, these planned projects amount to an overall pipeline of some 220 GW of interest in developing renewable energy in South Africa. The projects span all technologies: solar PV, wind, standalone batteries, and hybrid solar or wind and battery energy storage systems. Solar PV continues to be the predominant technology. The survey also reflects the geographical location of the planned projects, by technology and by type. This information can then be mapped in relation to the regional transmission corridors and substations of the national grid. Interestingly, the survey shows growth more widely across different provinces of the country, notably in the North West, Limpopo and Mpumalanga (primarily wind energy), and the Free State, with demand still strong in the
The annual SAREGS provides a valuable guide for the NTCSA and critical insights for all involved in the sector, including planners, investors, IPPs, manufacturers, and EPC contractors.

From SAPVIA’s perspective Stakeholders across South Africa’s renewable energy sector joined the much-anticipated SAREGS 2025 Results webinar on 27 October 2025, marking a key moment in the sector’s collaborative efforts to align renewable energy project development with national grid planning. The 4th Annual South African Renewable Energy Grid Survey (SAREGS), conducted in partnership with the NTCSA, provides crucial insights into the state of grid capacity, project development, and emerging trends such as wheeling and corporate power procurement. This year’s results underline the sector’s rapid growth and the urgent need for coordinated infrastructure expansion to unlock stranded renewable capacity. Key findings Wheeling and o§-taker dynamics: The latest survey reflects a significant shi¤ towards wheeling arrangements and pri- vate power purchase agreements, following the approv- al of South Africa’s Wheeling Framework. Data collected provides visibility into corporate procurement trends and third-party grid access. Identifying grid congestion hotspots: SAREGS 2025 high- lights areas where grid constraints have delayed or stalled projects. These insights are expected to help the NTCSA and Eskom prioritise transmission upgrades in high-demand zones, aligning investment with confirmed project pipelines. Policy integration: The survey continues to feed directly into key national planning tools including the Transmis- sion Development Plan and the Congestion Curtailment Proposal, which aims to free up 3.4 GW of stranded capacity in constrained regions. The 2025 Renewable Energy Grid Survey also highlighted continued momentum and scaling across the sector. Total reported capacity planned now exceeds 220 GW. Installed capacity surged by 86 GW compared to 2024. Development-stage projects grew by 60 GW, signalling a robust pipeline. Hybrid systems now represent 46% of total contracted ca- pacity compared to 25% in the previous year. 190 additional contributors participated, reflecting expand- ing industry engagement. This year’s survey again reaffirmed the industry’s willingness to share project data to support coordinated transmission planning. To maintain commercial confidentiality, raw survey data remains under the sole management of the NTCSA’s planning team; SAPVIA and SAWEA receive only aggregated insights. “The SAREGS results demonstrate that the renewable energy industry is more than ready to respond to its allocation in the recently announced IRP 2025. The survey provides a data-driven view of where the transmission and distribution bottlenecks are and, more importantly, where transmission infrastructure development should be prioritised. Industry and the NTCSA are now better equipped to work together to unlock capacity where it’s needed most,” said Dr Rethabile Melamu, CEO of SAPVIA. “With the IRP and the Wheeling Framework now in place, these results provide the foundation for a more efficient and
Northern, Western and Eastern Cape but static in Gauteng. From the indicated readiness/timing of the planned projects by Type A, B or C, the NTCSA can also gauge timing of the need for new transmission substations to be built. Noting that main transmission substations (MTSs) typically handle about 1 400 MW of power per substation, Marais said the NTCSA can work out where new substations will be needed and when, also taking account of the technologies to be used in the respective projects and their particular demands/impact on the grid. Marais further noted a greater readiness from private sector players to provide ancillary services, which would include reserves, black start capabilities, and reactive power supply, using different technologies. As well as providing a valuable guide for the NTCSA, the annual SAREGS provides critical insights for planners, investors, IPPs, manufacturers, EPC contractors, and other market players. A potential concern In the Q&A session following the presentation of the results, Marais emphasised that a key focus for the NTCSA is strengthening the grid, to control voltage levels and voltage angles, with a further key focus on enabling grid flexibility. Without flexibility, the new input from renewables that can be integrated into the grid is limited. With regard to the recently released Integrated Resource Plan, IRP 2025, Marais confirmed that the survey showed renewable energy components of the plan could readily be met. And looking beyond the country’s preoccupation with supplying enough electricity to meet demand consistently and sustainably, Marais highlighted another potential concern. He pointed out that the near-term interest in renewable energy development amounts to 72 GW (on the upside), whereas the forecast load for the near term is, comparatively, 20 to 24 GW. This means the rollout of renewables projects will need to be contained to meet electricity demand; and/or the economy and in turn electricity demand will need to grow more strongly than is currently forecast: if electricity supply from new renewables build were to surpass demand, the value of the output (and return on the investment) would fall to zero. The results of the SAREGS are shared on the NTCSA website – this screenshot illustrates renewable energy projects planned to 2034, by technology and location.

The opportunity: The sector’s readiness shows that South Africa can exceed current policy targets, po- tentially accelerating decarbonisation, job creation, and energy security. The challenge: Without corresponding grid invest- ment and enabling regulatory reform, much of this capacity risks remaining stranded, delaying the country’s energy transition. However, through SAREGS, NTCSA has a robust, data- driven tool to map and guide transmission development proactively across the country. The findings reinforce the urgent need to fast-track transmission infrastructure build, modernise grid operations, and adopt flexible planning frameworks that can accommodate faster renewable uptake than currently envisioned by the IRP. “The SAREGS 2025 results make it clear that South Africa’s renewable energy sector is ready, and eager to deliver,” says Govender. “With 60 GW of wind projects planned for grid connection within seven years, it is clear that the pipeline is ahead of policy, and the next frontier lies in unlocking grid access to convert this potential into usable generation capacity.” Key findings Wind and wind hybrid projects now account for over 110 GW, representing more than 50% of total report- ed planned capacity. Wind and wind + BESS – 60 GW. Wind projects Type A (in advanced development) – 17 GW. Industry engagement has surged with 673 contribu- tors in 2025 (483 in 2024). Project maturity continues to strengthen, with 72 GW classified as Type A (advanced development) and 45 GW as Type B (under development). Geographically, mature developments remain con- centrated in the Cape and Hydra regions, with new projects expanding into previously underused grid zones. An increasing number of projects now provide ancil- lary services – enhancing grid resilience. The sector is showing a strategic shift towards hybrid and co-located projects, optimising land use, gener- ation profiles, and grid efficiency. SAREGS continues to inform national planning in- struments, including the Transmission Development Plan (TDP), and Integrated Transmission Projects (ITPs).
transparent grid planning process that supports public and private sector investment.” SAREGS 2024 delivered valuable stakeholder data, representing over 120 GW of South African energy generation projects under development. The 2025 results reflect a maturing collaboration between government, grid operators, and the private sector. The insights generated will inform Eskom’s TDP and Grid Capacity Connection Assessments (GCCA), helping to align infrastructure delivery with the pace of renewable energy development. SAPVIA and SAWEA have called on independent power producers to continue engaging with the survey process in future iterations to ensure planning remains responsive to market realities. Comment from SAWEA The 2025 South African Renewable Energy Grid Survey reveals 72 GW of renewable energy projects at advanced stages of development – projects that could be ready to connect to the grid within the next seven years. This aligns with the 71.7 GW total capacity (wind and solar PV combined) envisioned in the Integrated Resource Plan (IRP) 2025 over the longer timeframe of a 16-year horizon. The survey reaffirms that South Africa’s renewable energy sector is aligned with IRP ambitions – and well ahead of them – demonstrating investor confidence, project maturity, and delivery readiness across the value chain. Led by the NTCSA in collaboration with the South African Wind Energy Association and the South African Photovoltaic Industry Association, SAREGS continues to serve as a critical coordination tool that aligns the national development pipeline with transmission planning and investment decisions. It emphasises the growing need for collaborative action between industry and government to ensure grid infrastructure keeps pace with market momentum. “The survey shows exponential growth across all technologies in renewable energy, with wind increasing from 43.8 GW in 2024 to as much as 60 GW this year, (excluding hybrid projects),” says Niveshen Govender, CEO of SAWEA. Over the past four years, the renewable energy pipeline has expanded from 63 GW in 2022 to 220 GW in 2025, a more than threefold increase, highlighting the sector’s sustained growth and the urgency of grid expansion, flexibility, and modernisation to support accelerated deployment. Aligning with the IRP, implications for wind energy The IRP 2025 allocates 43 GW of new onshore wind capacity by 2042, averaging roughly 2.7 GW per year. In contrast, SAREGS 2025 identifies over 60 GW of wind projects already in development, including 17 GW of advanced or shovel-ready capacity with most of this capacity expected to come online in the next five years. This gap between policy allocation and pipeline reality presents a strategic opportunity and a critical challenge.
