Smart tech tricks to beat winter electricity bills
The numbers are enough to send shivers down your spine—and not just from the cold. With Eskom's freshly implemented 12.74% tariff increase, South Africans face unprecedented electricity costs just as winter temperatures plummet. For households using Eskom's Homeflex tariff, peak winter rates now exceed R7 per kilowatt-hour, turning even basic comfort into a luxury.
'Running a single 2,000W oil heater for eight hours nightly could cost over R3,000 this winter season—and that's just for one room,' warns Dr. Andrew Dickson, Engineering Executive at CBI-electric: low voltage. 'The average family could see their monthly electricity bill jump by R300 or more.'
But according to Dr. Dickson, South Africans don't need to choose between warmth and financial stability. The solution lies in combining smart technology with strategic energy habits.
10 Smart Ways to Stay Warm While Cutting Costs
1. Know Your Energy Enemies
Most households waste electricity without realizing it. 'If you don't understand how much power your appliances consume, you can't make informed decisions about cutting back,' says Dr. Dickson. Smart monitoring devices reveal which appliances are the true budget-killers, allowing targeted energy savings where they matter most.
2. Prevent Power Pile-Ups
Modern smart home systems offer load management capabilities that prevent multiple energy-hungry devices from running simultaneously. 'Rather than having your geyser, heater, and oven competing for power at the same time, smart automation staggers their operation, reducing peak demand and preventing system overload,' explains Dr. Dickson.
3. Set Smart Time Boundaries
Why heat water all day when you only need it for morning and evening? Smart controllers let you specify precise operating durations for appliances. 'Running your geyser for just two hours instead of continuously can dramatically reduce consumption while still ensuring hot water when needed,' notes Dr. Dickson.
4. Embrace Off-Peak Power
Timing is everything. The difference between peak and off-peak rates can be staggering—as much as R6 per kilowatt-hour. 'Programming your washing machine to run between 10pm and 5am could cost as little as R1.01/kWh, compared to over R7/kWh during peak times,' Dr. Dickson points out. Even flat-rate customers benefit from reducing overall grid strain.
5. Outsmart the Winter Spike
Household energy consumption typically jumps by at least 20% in winter as heating systems work overtime. Smart scheduling ensures appliances run only when needed. 'Program your heater to switch on 30 minutes before you wake up,' suggests Dr. Dickson. 'You'll enjoy a warm room without wasting electricity all night.'
6. Let Weather Dictate Energy Use
Advanced smart systems can respond to environmental conditions automatically. 'When temperatures drop below a certain threshold or daylight fades early on cloudy winter days, your lights and heating can adjust accordingly,' says Dr. Dickson. This means no more paying to heat an empty house when the weather unexpectedly warms up.
7. Control Your Home from Anywhere
Left in a rush and can't remember if you turned off the heater? 'Smart home technologies allow remote control of connected appliances from your smartphone, wherever you are,' Dr. Dickson explains. This flexibility prevents wasted energy when plans change.
8. Defeat the Stealth Energy Thieves
That innocent-looking 'sleep mode' on your TV, computer, and kitchen appliances might be silently draining your wallet. 'Electronics in standby mode can collectively consume more electricity than when actively used,' warns Dr. Dickson. Smart plugs can automatically cut power to these devices when not needed.
9. Maximize Your Solar Investment
As more South Africans invest in solar systems to buffer against rising electricity costs, protecting that investment becomes crucial. 'Smart power indicators help solar users manage energy more effectively when grid power is unavailable,' says Dr. Dickson. 'They can disconnect non-essential appliances automatically, preserving battery life until systems recharge.'
10. Shield Your Appliances
Even with reduced load shedding, voltage fluctuations and power surges remain common, especially in areas with aging infrastructure. 'Smart technology can detect unsafe voltage levels and automatically cut electricity flow until it stabilizes,' explains Dr. Dickson. 'This protects expensive appliances like refrigerators and entertainment systems from costly damage.'
Contrary to popular belief, adopting smart home technology doesn't mean rewiring your entire house. 'Devices like smart plugs, isolators, and controllers can be easily installed by an electrician without additional wiring or hubs,' Dr. Dickson emphasizes. 'Even renters can benefit from the latest smart adaptors, which can be taken along when relocating.'
As winter tightens its grip and electricity costs soar, these smart strategies offer South Africans a way to maintain comfort without financial strain. 'Even small changes can make a big difference,' concludes Dr. Dickson. 'By using smart technology to manage energy use, South Africans can stay warm, save money, and feel more in control of their electricity bills.

Musk's Starlink License Decision Up to South African Regulator
The decision whether to award Elon Musk's Starlink an operating license in South Africa will ultimately rest with the country's industry regulator, a government minister said. The Pretoria-born Musk has indicated that he wants Starlink internet services, which rely on a constellation of low-Earth orbit satellites, to be made available in Africa's largest economy. But he has refused to relinquish any equity in the business to comply with Black-empowerment rules — which he says are 'openly racist.'

From banking to beauty: Meet Beauty on TApp founder Mathebe Ngwenya
Mathebe Ngwenya's online skincare platform Beauty on TApp now has four store locations. She always had a passion for creativity before venturing into finance. Mathebe recently got married and credits her partner as supportive and holds her accountable in business. _______________________________________________________________________ What started out as just a little girl's passion turned into a lucrative e-commerce business centred on clean beauty. Mathebe Ngwenya has always had a creative mind and looked up to the matriarchal figures in her life as the original 'glam girls'. But she couldn't deny the analytical side to her either, which shifted her trajectory to becoming chartered accountant. 'I've kind of always had this passion for both creativity as well as finance and numbers. And I think the two coming together is what's really kind of helped me build Beauty on TApp,' Mathebe tells TRUELOVE. Beauty on TApp has been the go-to destination for curated beauty, skincare and wellness products since 2015 that blossomed from being a digital-first platform to opening their first brick and mortar store in 2023. Just two years later, Mathebe's baby has grown to four store locations, including in Durban's Gateway Theatre of Shopping and Johannesburg's Fourways Mall. View this post on Instagram A post shared by Mathebe Ngwenya (@mathebe_ngwenya_) Lessons learnt along the way Beyond retailing popular international and local beauty brands, Beauty on TApp is also the home of two fast-growing in-house labels, Pastry Skincare, known for its science-backed and effective formulations made with the local climate in mind, and B'Air Skincare, an affordable and minimalist but effective range. With her background in finance, Mathebe takes us through some of the lessons she's learnt since opening her first physical Beauty on TApp store, from the science behind merchandising and keeping stock to paying rent. 'I think at our first store, those are things that we still had to learn versus by the fourth store. You kind of understand all of that and you're able to better negotiate things like your lease and [you're] able to talk to brands in terms of terms and how they extend those terms to you. Visual merchandising as well, how to place brands and so on. And so they're multiple lessons that you learned along the way.' View this post on Instagram A post shared by Pastry Skincare (@pastry_skincare) With a new physical store coming double the size of their current offerings as well as a national and continental expansion, Mathebe's plans for Beauty on TApp are just beginning. Support from all sides Mathebe doesn't do it all alone. The entrepreneur recently got married and shares how her partnership gave her the support and freedom she needed when pushing forward with her dreams for Beauty on TApp. Mathebe gushes, 'It's been really incredible, at least to have somebody who calls me accountable, even in business as well, and who's really supportive. 'And so it's been really great just having somebody who understands me, understands the business from all facets. From the digital side, marketing side and everything, he's just very supportive. So it's been a really great ride as well.'

Platinum Chases Gold Hitting A Four Year High Of $1218/oz
Platinum has returned as a precious metals star, delivery fat profits as investors rotate funds out of gold, the sector leader. Platinum's sister metal palladium is also rising strongly. Both platinum and palladium seem likely to continue outperforming as a decade of oversupply gives way to signs of a shortage developing. A miner handles a piece of raw platinum ore in South Africa. Photographer: Waldo Swiegers/Bloomberg Over the past month the platinum price has risen by 24% to a four-year high of $1218 an ounce, while palladium is up 13% at $1077/oz. Gold, on the other hand, has risen by 1.5% to $3205/oz, though that modest move needs to be seen against a background of three spectacular years of soaring demand and an 83% increase from a price around $1810/oz in June 2022. The platinum rebound has been a long time coming though some investors might remember that it wasn't that long ago when the platinum price was comfortably higher than gold. In mid-2008 an ounce of platinum cost $2068, more than double gold which was selling for $903/oz. Demand for platinum and palladium has traditionally been driven by a combination of jewelry and industrial uses, especially for in the catalytic converters of internal combustion engines where they play a role in minimising the emission of environmentally damaging nitrous oxide. But in 2015 the platinum market crashed after it was revealed that the big German car maker Volkswagen had been falsifying exhaust system measurement sparking a scandal dubbed Dieselgate. Within months the platinum price had crashed to just $804/oz. Palladium, which is the preferred metal in the exhausts of gasoline powered vehicles, also fell but not as steeply. Further weighing on the prices of platinum and palladium has been the rise in sales of electric vehicles, which do not require a catalytic converter – though hybrid electric cars do, and in some case their converters require a heavier coating of platinum or palladium.

Mines in South Africa, the major source of platinum, have cut back during the years of low prices, as have the palladium mines of Russia which are the primary source of that metal. A measure of the changing fundamentals of the platinum market came last month in a report from the World Platinum Investment Council (WPIC) which forecast a supply deficit this year of 966,000oz, the third consecutive deficit year. More importantly, the latest deficit could put pressure on the platinum price because the WPIC is forecasting that the stockpile will shrink to 2.16 million ounces, enough to meet just three months of demand. The sudden shift in the platinum market, which has really been 10-years in the making, has sparked a sharp increase in the prices of platinum miners with the biggest beneficiary being Valterra Platinum, the renamed Anglo American Platinum. Since listing earlier this month on the London Stock Exchange Valterra shares have followed the platinum price, up 24%. Smaller platinum stocks have done better. Zimplats, a Zimbabwe-focused miner controlled by South Africa's Impala Platinum has risen by 60% over the past month while Australian-listed Southern Palladium, which is planning to develop a new platinum mine in South Africa is up 120%.
