Starting June 1, 2024, South Africa will enforce critical changes to motor regulations that businesses must heed. The new mandate requires all new low-voltage motors to meet the IE3 efficiency standard.
On June 3, 2024, a compulsory specification was Gazetted outlining efficiency requirements for electric motors (VC9113), which will take effect 12 months after the notice publication. These regulations impact motor importers and manufacturers. After June 1, 2025, motors with a KW rating larger than .75KW will need to be IE3 motors for low-voltage applications in South Africa, though businesses have until 31 May 2026 to sell off existing stock of IE1 and IE2 motors.
This shift aims to address South Africa’s energy consumption, which is a significant contributor to global energy use, with electric motors accounting for 40% of the world’s electrical energy consumption.
The global push for higher energy efficiency is not just an environmental initiative; it’s a business necessity. IE3 motors, which are 3% more efficient than their IE1 counterparts, offer long-term cost savings by reducing energy consumption and enhancing reliability, all while aligning with global standards. South Africa is leading the charge in Africa with this regulation, marking a step toward reducing the country’s energy footprint.
The transition to IE3 motors will affect approximately 99% of South Africa’s low-voltage motors, which are used in industries like mining, manufacturing, HVAC&R and plumbing. However, many engineers and businesses remain unaware of the scope of the change. With the sale of IE1 motors ending by June 2025, companies that don’t prepare for this transition risk operational delays. The window to purchase or use IE1 stock is closing, and now is the time to plan ahead.
From June 1, 2024, importers were no longer able to bring IE1 or IE2 motors into the country for low-voltage applications. The grace period for selling IE1 and IE2 stock ends in June 2025, after which companies will require special permits to import remaining stock—if they can secure it at all. With rising electricity costs, energy-efficient motors have become even more vital. While IE3 motors come with a higher upfront cost, they offer substantial savings by drastically reducing energy consumption.
Plan now to avoid the rush
Businesses should revise procurement processes and technical specifications to comply with the new IE3 standards. It’s not just about avoiding penalties; it’s about future-proofing operations and reducing energy costs. The transition to IE3 motors will not only ensure compliance but also provide long-term savings. For motors running 24/7, the additional cost of an IE3 motor can be recouped in as little as seven months. However, most motors typically operate no more than eight hours a day.
If your business is still specifying IE1 motors, now is the time to make the switch to IE3. If this change is not made, there will be no stock available after the new regulations take effect. Engineers and decision-makers must update tender specifications and inventory plans immediately.
As global trends push for higher efficiency standards, IE3 is just the beginning. IE4 and IE5 motors, which offer even higher efficiency ratings, are already being introduced in some regions. South Africa is expected to eventually adopt these standards. The IE3 regulation presents an opportunity for South Africa to lead in energy efficiency, but businesses need to act quickly to stay ahead.
The message is clear: by June 1, 2025, IE1 motors will no longer be available for low-voltage applications. Companies that continue to specify these outdated motors will face significant disruptions. Now is the time to transition to IE3 motors and secure the long-term financial and environmental benefits they offer.
For engineers, procurement teams and businesses, this upcoming regulation marks a turning point. Let this be a wake-up call to ensure you’re compliant and ready to embrace the future of energy-efficient motors.
