The evolving landscape of solar energy for South African industries
As South Africa navigates its energy future, the time to rethink solar is now. Uncover how a new era of energy diversity could redefine sustainability and profits for businesses in the C&I sectors.

In a world where energy dynamics are constantly shifting, Sakhile Ngcongwane, Business Development Manager at SolarAfrica, said that renewable energy is no longer confined to the simplistic installation of a few rooftop panels.
For businesses intent on maximising the benefits, diversification is the key.
As South Africa's energy landscape transforms, mixed policy signals are raising questions about solar energy's continuing value, particularly for large energy consumers in the commercial and industrial (C&I) sectors.
Ngcongwane offered reassurance: solar still retains its merits, albeit in a more complex role than in the past.
While the current stability of load shedding may lead some to believe that renewable energy has slipped down the national agenda, the reality is more nuanced.
The carbon tax, initially designed to incentivise reduced greenhouse gas emissions, is stalling, primarily due to lobbying from corporate interests.

Since its inception in 2019, Phase 1 of this tax allowed companies to evade payments for up to 95% of their emissions, rendering it largely ineffectual.
Despite proposed changes to increase the carbon tax in the future, recent budget statements have revealed a dampened commitment, with tax-free allowances extended to 2030 and stricter penalties seemingly put on the back burner.
As geopolitical volatility shapes policy decisions globaly, South Africa's weak stance on carbon pricing may ultimately hinder its renewable ambitions.
Interestingly, external influences, such as the EU's Carbon Border Adjustment Mechanism (CBAM), are set to put pressure on local exporters who may face hefty tariffs if their products do not adhere to equivalent carbon standards.
Starting from January 2026, businesses with high emissions that are not adequately accounted for by carbon pricing in South Africa may face significant competitive disadvantages.
Yet, the case for solar retains considerable strength.
As a means of energy production, solar offers not just environmental benefits but also substantial cost savings for businesses.
By generating energy on-site, particularly during peak hours when electricity costs soar, companies can lower their dependence on expensive utility services, mitigate peak demand charges, and gain control over their long-term energy expenditures.
However, Eskom's newly implemented Retail Tariff Plan (RTP) presents fresh challenges.
This restructuring, characterised by increased fixed costs and lower variable rates, has altered how major energy users are billed.
While it aims to provide cost predictability, it diminishes savings from self-generated energy, necessitating a more strategic approach to energy consumption and management.
Herein lies the opportunity for what Ngcongwane terms "energy stacking."
This methodology allows businesses to combine different energy sources: utilising solar for self-generation, battery energy storage systems (BESS) for reliability, and "wheeling" to secure energy at scale, untethered by limitations such as rooftop space. Additionally, trading surplus energy can offer flexibility and drive down costs.
This diversified energy strategy not only enhances cost savings and energy security but also bolsters sustainability credentials, ensuring compliance with emerging carbon regulations and increasingly rigorous environmental, social, and governance (ESG) standards.
It is clear: solar energy is evolving.
While traditional systems might have seemed adequate in the past, the future lies in a layered approach, blending various energy sources and technologies to create robust, cost-efficient structures.
For C&I leaders willing to act now, the adoption of flexible, diversified energy frameworks could result in significant carbon reductions and a long-term competitive edge in a rapidly changing market.

Outa urges Transport Minister to suspend penalties for motorists amid driving licence backlog
The Organisation Undoing Tax Abuse (Outa) has asked Transport Minister to suspend penalties related to expired driver's licence cards for motorists who have applied for renewals. Image: Karen Sandison / Independent Media The Organisation Undoing Tax Abuse (Outa) has called for the Minister of Transport, Barbara Creecy, to waive fines and temporary licences for those whose new driving cards are stuck in the ongoing backlog. This comes as the Department of Transport (DoT) scrambles to clear the driving licence card backlog, which was caused by the breakdown of the sole card-printing machine earlier in April. Last week, DoT reported a backlog of 690,000, down roughly 43,000 from the 733,000 that was announced a week ago. On Tuesday, Outa's Advocate Stefanie Fick wrote to Creecy and asked her to consider announcing a moratorium on fines related to expired driver's licence cards for motorists who have already applied for renewals and that no temporary licences should be required until all backlogs have been cleared. She also requested the department to consider issuing public communication of this moratorium through all official channels, including the Road Traffic Management Corporation (RTMC), provincial traffic authorities and traditional and social media.

Next Stay Close ✕ Fick added that the department must provide clarity to all enforcement officials to prevent unwarranted fines and harassment of motorists. 'Recent reports confirm that the Department of Transport is currently experiencing a backlog of approximately 733,000 to 747,500 unprinted licence cards, with delays attributed to issues with card machines, administrative inefficiencies and high demand," Fick said, adding that many law-abiding motorists could be issued fines by law enforcement officials for not physically possessing their renewed cards, even when they hold receipts or valid temporary licences proving compliance. She said this practice would be unfair, adding that the public is being penalised for failures which is not their making but because of a broken system that is currently unable to meet service delivery expectations. DoT spokesperson Collin Msibi confirmed that the department received the letter and it is currently being processed internally for the Minister's attention. Fick said it was important to note that during the Covid-19 pandemic, the DoT recognised the exceptional circumstances and issued blanket extensions on the validity of expired driver's licences, allowing the public reasonable leeway while the system was caught up. She said this temporary relief was an example of fair, compassionate governance in the face of operational disruption. 'We urge the department to take a similar approach now, especially given that this crisis stems from internal systemic failures rather than a national emergency,' Fick said. Creecy recently revealed that the department has spent over R12 million on the repair and maintenance of the printing machine over the past three years. The department has been trying to procure another machine for years, but repeatedly cancelled and reissued the tender. In August last year, the department announced that it had appointed Idemia and Security South Africa as the preferred bidder for a tender to print new driving licence smart cards. However, Outa's investigation uncovered irregularities and handed the report to Creecy, who in turn passed it to the Auditor-General (AG). In March, Creecy announced that the AG investigation identified instances of non-compliance with the required procurement procedures, and added that she instructed her department to lodge a High Court application for a declaratory order regarding the tender. Fick said Outa is still waiting for clarity on the contract process.

Learning and Development is a Business Imperative
Lucia Mabasa is Chief Executive Officer of pinpoint one human resources. Image: supplied By LUCIA MABASA Staff training is as important for a manager as hitting your sales targets. You wouldn't let anyone else set those targets yet far too many managers do exactly that for training: shifting the responsibility to Human Resources departments. The problem is that delegation can very quickly become abdication, with negative consequences for the staff, the manager, and the company. Properly conceptualized and executed learning and development (L&D), should be neither a chore nor a nice-to-have. In fact, in this rapidly changing continually disrupted world that we live in L&D has become increasingly important. Companies often complain that the talent pool is far too shallow to meet their needs when they cast their net for new hires, but those same companies are in all probability not doing anything to create an internal pipeline of skilled talent. Great companies, through the ages, have seen the need and the value in developing their own skilled employees. For them, the question today is not what to teach but rather how fast their people can learn. The advent of the Fourth Industrial Revolution has unlocked learning opportunities in ways that were unimaginable before. At one time training was generic, sometimes rote, always in a classroom. Now it can be asynchronous, one-on-one in person or remote or both. It can even be co-created with AI. The output can range from short skills courses to formal credentials. Video Player is loading.

Next Stay Close ✕ Like the world it seeks to unlock, learning is far more agile than ever before in scope and scale. As always it is the CEO that sets the tone for any company and learning and development are no different. A CEO who is actively learning both inspires and allows their staff to do the same by physically creating a culture of learning in the company. Truly effective L&D though requires the involvement of the full gamut of the C-suite: The CFO needs to ensure that the old bugbear Return for Investment (ROI) is realised for the company; the CIO must implement and support the digital infrastructure required for modern learning while the Chief People Officer must create an environment that enables and encourages learning at every level. Creating an HR enabled learning environment is so much more than just measuring attendance and completion metrics, it is about putting in place mechanisms to ensure that the training does what it is supposed to: unlock the potential of the staff who have been selected to participate in this development. Sometimes those development interventions can be deceptively simple yet exponentially effective, like the time a company decided to send a manager to the Voice Clinic. The manager who was full of promise but failing, emerged as phenomenal deal maker and closer, having unlocked the confidence to speak in public with the actual abilities that were always on show in the office. We need to move away from a one size-fits-all approach to learning and development; the companies that are filled with curiosity about the different kinds of learning programmes that are available and look to technology not as a mechanism to police their personnel; focusing on algorithms to manage people and track progress, but as a way of developing skills are the companies that will flourish. As businesses evolve, so too do their needs, business leaders need to use L&D to meet both their short term staffing – and leadership – needs, as well as meet the challenges that might be looming five years down the line. Lifting your gaze beyond the immediate to the mid-future is perhaps the most important, because a five-year horizon provides a company with the runway to develop a proper in-house talent pipeline. When you get that right, you shouldn't need to always look outside the organisation for the talent you need, but just as there are different ways of learning for different people, so too are there different ways of attracting talent. Sometimes it makes sense to look beyond the strictures of the company organization if that is what the company needs, but equally that should only be done if the company has done everything it can to grow its own timber because creating a culture of always looking outside for leadership candidates can also be expensive and self-defeating. We have the tools like never before, which help reduce – and even eradicate - the traditional barriers to further education. As business leaders, we do not have an excuse not to act. The greatest incentive for traditional business leaders is that over and above the very laudable goals of developing the staff that work for you, it makes real business sense too with a tangible, positive, impact on the bottom line. There are business leaders who complain that there is no upside to training staff only to have them be poached by head hunters from rival companies. It's a valid argument but one that is easily trumped by its corollary: not training your staff and having them stay. *Lucia Mabasa is Chief Executive Officer of pinpoint one human resources, a proudly South African black women owned executive search firm. pinpoint one human resources provides executive search solutions in the demand for C suite, specialist and critical skills across industries and functional disciplines, in South Africa and across Africa.
