Fuelling the future: Solar-powered charging for South Africa's electric trucks
This means the industry's need to transition to cleaner energy solutions is becoming increasingly important, particularly as climate control becomes a more significant issue.
Several electric commercial vehicles and trucks have been introduced in recent years. The Tesla Semi, for example, has an estimated range of more than 800km when fully loaded, according to the manufacturer. Moreover, the battery pack can be charged to 70% in around 30 minutes, making it about as practical as a conventional diesel-powered truck.
Tesla isn't the only brand that sells electric trucks. In recent years, Mercedes-Benz, Volvo and Scania have introduced them. However, in a country such as South Africa, where long-distance driving is routine, a superior charging network is needed to allow the use of fully electric trucks and commercial vehicles.
The latest statistics suggest that South Africa has about 350 public chargers across the country. While that's enough to support the current number of electric vehicles, it would need to be significantly expanded to accommodate electric trucks.
Recognising this, electric vehicle charging company Zero Carbon Charge is implementing an ambitious plan to roll out 120 solar-powered truck charging stations along national highways.
According to the company, this will be the first of its kind, with the off-grid infrastructure providing 100% green energy to charge electric trucks nationwide. The first six sites, expected to be built on the N3 between Johannesburg and Durban, would allow electric trucks to travel between South Africa's economic hub and the busiest port in the country.
South Africa-based City Logistics recently conducted a trial with an electric truck. The drivers found much to like about the battery-powered vehicle.
A four-tonne Mitsubishi eCanter truck was used on a set 80km route, meaning the truck was never at risk of depleting its battery. The trial showed that the truck could complete the route using just 40% to 50% of its battery, proving that electric trucks can fit seamlessly into urban and regional delivery operations.
The logistics company charged their truck at the depot but solar-powered charging stations could significantly ease the process for electric truck operators.
It's worth noting that the eCanter could charge from 20% to 100% in less than an hour when plugged into a 50kW charger. However, the advent of an EV truck charging network would allow companies to adopt electric trucks with confidence.
Drivers noted the eCanter's efficiency and smooth driving experience. The truck's electric motor delivers instant torque from 0 r/min, making it feel more responsive than its diesel counterparts.
It's also quieter and smoother, offering a comfortable driving experience while maintaining strong performance. Additionally, recharging the batteries is significantly cheaper than refuelling a diesel truck.
'Electric trucks present a major opportunity for the logistics industry,' said City Logistics chief executive Ryan Gaines.
'The potential savings in fuel and maintenance alone make them an attractive prospect and advancements in charging infrastructure will only accelerate their adoption. As the industry moves toward lower-emission transport solutions, companies must assess how best to integrate electric vehicles into their fleets in the near future.'
Globally, electric trucks — also known as heavy electric vehicles — are growing in popularity, with sales increasing annually. According to a recent report, the electric truck market is expected to increase by $20.32 billion by 2028, at a compound annual growth rate of 35.44%.
As mentioned, many companies are seeing the long-term cost benefits, with reduced fuel expenditure and less frequent maintenance being two of several drawcards.
One of the world's largest food and beverage companies, PepsiCo, announced in May 2024 that it would introduce 50 Tesla Semi trucks to its fleet.
The American giant is one of the first global companies to employ the Tesla in daily operations. The trucks will be supported by 75 Ford E-Transit electric vans for shorter journeys.
At the time, PepsiCo said these additions would help the company reach its goal of net zero emissions by 2040. While South Africa's transition is still in its early stages, initiatives like Zero Carbon Charge are laying the foundation for a similar shift.

After 120 years, Murray & Roberts heads towards liquidation
Murray & Roberts, the multinational engineering and construction group, will not oppose liquidation proceedings initiated by a creditor, seeking final winding up of the business. Image: Supplied After 120 years, Murray & Roberts Limited (MRL), a South African engineering and construction stalwart founded in 1902, faces liquidation. The company, which listed on the JSE in 1951 and merged with Roberts Construction in 1967, did not oppose creditor-initiated proceedings in the Gauteng High Court. This decision follows a prolonged period of financial distress that rendered the holding company insolvent after the sale of its core assets. On August 15, the group informed shareholders that a creditor had initiated liquidation proceedings in the Gauteng Division of the High Court of South Africa, seeking a final or provisional winding up order. According to reports Murray & Roberts stated, "Given the company's financial position, Murray & Roberts does not intend to oppose the liquidation application." The company plans to continue engaging with its legal advisors and will update shareholders on further material developments. On November 22, 2024, the company was subsequently placed on business rescue following significant liquidity constraints by the South African-based international engineering and construction group over a prolonged period. The business rescue practitioners said that creditors had approved MRL's business rescue plan on April 8, and in terms of this plan, MRL's main assets, its mining businesses, would be sold to a consortium of investors led by South Africa-based asset management firm Differential Capital.

Sassa flags 'unlawful' grant deductions by insurance companies
The South African Social Security Agency (Sassa) has raised concern about the surge in 'unlawful' deductions by financial services providers, such as insurance companies and funeral schemes, targeting grant beneficiaries. The agency said it has been receiving complaints from beneficiaries who have had money deducted using Sassa's name without permission. Sassa CEO Themba Matlou said the agency does not work with financial service providers and has no authority to make deductions without the consent of the beneficiaries. 'We have respect for our beneficiaries and the act governing social assistance and we will never do anything to short change our clients,' he said. 'Your money is your money, If you qualify for a grant the money belongs to you and as Sassa we have no right, nor authority, to dictate how you use it.' He urged beneficiaries who have fallen victim to visit the Sassa local office to report the matter for investigation. 'Alternatively, clients who dispute signing a funeral policy with the financial services provider are advised to dispute the deduction by sending an SMS to 34548 with their identity number and the financial services provider's name. They should also visit the insurer or the services provider to cancel the policy.' According to the Social Assistance Act, the agency only allows one deduction per month of no more than 10% of the grant for a funeral policy issued by an insurer registered under the Long-term Insurance Act to be made directly from a social grant. Funeral deductions are not permitted from child-related grants such as the child support grant, care dependency grant or foster child grant. Temporary grants are also excluded, the agency said. 'The regulation says the beneficiary of the social grant must consent to such deduction by electronic communication or any other means of communication and has submitted such consent by electronic communication or any other means of communication to the agency.'

Closing the gender wealth gap needs systemic change — but women must also act
South African women retire with only 71% of the wealth that men do. Photo: File South African women still face major challenges when it comes to building wealth. In fact, the wealth gap between men and women in our country is wider than the global average. According to the WTW Global Gender Wealth Equity report, South African women retire with only 71% of the wealth that men do. This is lower than the global average of 74%. The difference becomes even greater in senior positions, where women who are managers and executives retire with just 62% of the wealth their male colleagues accumulate. There are many reasons for this. One of the biggest is unequal pay. Women's Report Africa points out that, in 2021, South African women earned only 78 cents for every rand earned by men. Shockingly, this was a decline from 89 cents in 2008. Furthermore, fewer women than men in South Africa are actually employed. Only 54.3% of working-age women are active in the economy compared to 64.9% of men. And the unemployment rate for women remains unacceptably high at 35.7%, according to date from Women are also more likely to take breaks from work to care for children or other family members. This often means lower earnings and less money saved over time. As a result of all these factors, many women struggle to save enough for retirement, which is a significant problem when you consider that, on average, women tend to live about six years longer than men. This means women actually need more money to cover those extra years. Even for high-earning women, the path to wealth creation is hindered by investment hesitancy. A 2023 study by Maya on Money and Satrix found that only 15% of women felt very confident about investing, compared to 42% of men. About a third of the women surveyed said they avoid investing because they don't know enough about it and nearly one in five said it makes them feel anxious or uncertain. Many women say they hold back from investing because they feel pressured to be financially cautious for the sake of their families. To change this, women — and those on the path to building wealth — need to start seeing investing as the powerful tool it can be to achieve financial independence. This journey starts with the understanding that they have to do more than just save in a bank account or stokvel. Investing in things like shares or exchange-traded funds can help money grow faster over time. Targeted education is one of the keys to investment success and programmes like the JSE's #SheInvests are useful ways for women to build skills and confidence in investing. Using tax-friendly products such as retirement annuities, pension funds and tax-free savings accounts can also make a big difference. These products offer tax breaks and help protect savings. It's especially important for women to take advantage of these during peak earning years to help make up for times when they might earn or save less. Women should also rethink how they see risk. Being cautious is smart but avoiding all risk can mean missing out on opportunities. Taking calculated risks, such as maintaining equity exposure within a diversified portfolio, is essential for achieving growth that keeps pace with inflation. Finally, good financial planning plays a critical role. A trusted adviser can help build a holistic strategy that balances short- and long-term goals, optimises tax efficiency and effectively incorporates retirement planning. Women may also have access to more sophisticated vehicles like managed portfolios or offshore investments, which require professional insight to manage effectively. Having a good financial adviser is especially helpful during life changes like a career break or divorce. Having support, especially at these times, can boost confidence and keep women on track on their wealth building journeys. But closing the gap certainly isn't the responsibility of women alone. It also requires that we improve the systems that hold women back. Businesses and the government have a key role to play in this. Employers need to look at how they pay and support women, offering flexible work, fair promotions and support for mothers returning to work. Ultimately, financial independence and personal wealth growth for women are more than just personal milestones — they are powerful drivers of broader social progress. When women thrive financially, households, communities and entire economies benefit. So, closing the gender wealth gap isn't just the right thing to do; it's essential for building a stronger, more resilient South Africa for all. Hein Klee is an executive at Nedbank Financial Planning.
