Henkel South Africa has taken a significant step towards a greener future with the official launch of its solar farm at the Alrode manufacturing plant. This groundbreaking initiative ensures that 100% of the plant’s electricity needs during daytime operations are met through renewable energy sources, reinforcing Henkel’s commitment to sustainability.
The newly installed solar farm boasts a peak capacity of 1.8 megawatts and is seamlessly integrated into the plant’s energy grid. This ensures uninterrupted and efficient energy use while significantly reducing reliance on fossil fuels. Beyond its operational benefits, the project aligns with Henkel’s broader sustainability goals and supports South Africa’s national 2050 carbon reduction targets.
Optimising Energy Efficiency Through Smart Integration
As a grid-tied installation, the solar farm adapts in real time to the plant’s energy needs. During daylight hours, the facility runs entirely on solar power, while at night, it draws from the national grid, supplemented by Henkel’s renewable energy certifications. This dual-source approach enables a 70% reduction in daytime electricity consumption, leading to a notable decrease in greenhouse gas emissions.
“Achieving 100% renewable energy sourcing for daytime operations is a proud moment for Henkel South Africa,” said Thelma Mamatlepa, Plant Manager at Henkel SA. “This project proves that sustainability and economic efficiency can go hand in hand, positioning us as a model for other industrial players in the country.”
Driving the Net-Zero Agenda
The solar farm is a key component of Henkel’s net-zero roadmap. In addition to transitioning to 100% renewable energy for daytime operations, Henkel is taking decisive steps to reduce its scope 1 and scope 2 emissions. Plans are already in motion to fully electrify the Alrode plant by 2025/2026, with the introduction of an advanced electrical boiler to replace traditional fossil-fuel-based systems. These efforts demonstrate Henkel’s unwavering commitment to climate action and meaningful sustainability progress.
A Holistic Approach to Sustainability
The solar farm is just one aspect of Henkel’s broader energy optimisation strategy at the Alrode plant. Over the past year, the company has implemented several complementary initiatives to enhance energy efficiency:
- Optimised Boiler Systems: Enhanced servicing, descaling, and advanced water treatment technologies have improved boiler efficiency and reduced energy consumption.
- Improved Insulation: Upgrades to mixers and steam lines minimise heat loss, ensuring energy is used effectively.
- Smart Production Scheduling: High-energy-demand processes are now scheduled during daylight hours to maximise solar power usage.
- Recycling and Water Reuse: Process water is repurposed for cleaning and operational needs, reducing water consumption.
- LED Lighting Upgrades: Energy-efficient LED lighting is being systematically introduced, starting with warehouses and extending to office spaces.
Employee-Led Innovation and Collaboration
The success of the solar project is also a testament to Henkel’s collaborative culture. Employees actively contributed by identifying energy-saving opportunities, refining operational processes, and championing sustainability efforts.
“From optimising motor operations to developing water-saving strategies, our employees have demonstrated remarkable ingenuity,” said Mamatlepa. “Their involvement underscores a shared commitment to sustainability and highlights the power of collective action.”
Looking Ahead: A Vision for Energy Independence
While the current solar installation does not include battery storage, Henkel plans to evaluate future investments in energy storage solutions to further enhance energy independence. Additionally, the plant’s energy monitoring systems will be upgraded to provide real-time tracking and deeper insights into consumption patterns, ensuring continuous optimisation.
The Alrode plant’s sustainability journey is part of Henkel’s science-based target to achieve absolute scope 1 and scope 2 emission reductions by 2030. It also supports South Africa’s broader energy transition, balancing economic growth with environmental responsibility.
Setting a Precedent for the Industry
Henkel’s solar project serves as an industry benchmark, showcasing how data-driven decision-making and employee engagement can drive sustainability success. The initiative provides valuable lessons for other sectors navigating South Africa’s energy challenges, including load shedding and escalating electricity costs.
“At Henkel, sustainability is more than just a target—it’s a responsibility,” said Veerabhadra Konakalla, Head of Sustainability, Health, and Environment HAT IMEA. “Our solar farm exemplifies the impact of innovation, investment, and collective determination. We are proud to contribute to a cleaner, more sustainable future for South Africa.”
