Henkel South Africa has reached a groundbreaking
milestone in its sustainability journey with the official launch of its solar farm at its Alrode
manufacturing plant. This transformative project ensures that 100% of the plant’s electricity needs
during daytime operations are met through renewable energy sources.
The solar farm, which boasts a peak capacity of 1.8 megawatts, is seamlessly integrated into the plant’s
energy grid, ensuring uninterrupted and efficient energy use. Beyond its operational benefits, this solar
installation exemplifies Henkel’s commitment to tackling global climate challenges while making
tangible contributions to South Africa’s national 2050 sustainability goals.
Revolutionising Renewable Energy Integration
The solar installation is grid-tied, allowing it to adapt to the plant’s energy needs in real time. During the
day, all energy requirements are met directly by the solar farm, while at night, the plant leverages
electricity from the grid, supplemented by Henkel’s existing renewable energy certifications. This dual
approach ensures sustainability without compromising operational continuity.
By reducing reliance on the national grid, the Alrode plant anticipates a 70% reduction in daytime
electricity consumption, translating into a significant 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 demonstrates that
sustainable operations and economic efficiency can co-exist, making us a model for other industrial
players in the country.”
Advancing Henkel’s Net-Zero Roadmap
The solar farm forms a key part of Henkel’s broader net-zero roadmap. In addition to achieving 100%
renewable electricity for daytime operations, Henkel is accelerating efforts to reduce its scope 1 and
scope 2 emissions. As part of this “Race towards net-zero,” Henkel aims to achieve full electrification of
its Alrode plant by 2025/2026, including the installation of an advanced electrical boiler to replace fossil-
fuel-based systems. These initiatives reflect Henkel’s steadfast commitment to addressing climate
change and driving meaningful sustainability progress.
Innovative Energy Efficiency Measures
The solar farm is the centerpiece of a broader energy optimisation strategy at the Alrode plant. Over the
past year, Henkel has implemented several complementary measures:
Optimised Boiler Systems: Henkel has overhauled its boiler operations, reducing energy
consumption through full servicing, descaling, and the introduction of advanced water
treatment technologies.
Improved Insulation: By insulating mixers and steam lines, the plant has minimised heat loss,
ensuring energy is conserved and efficiently utilised.
Smart Production Scheduling: High-energy-demand processes have been shifted to daylight
hours to maximise the benefits of solar energy.
Recycling and Water Reuse: Process water is now reused for cleaning and other operational
needs, reducing resource consumption.
LED Lighting Upgrades: Energy-efficient LED lighting is being rolled out across the plant, starting
with warehouses and expanding to office spaces.
Collaboration and Employee Empowerment
The solar project was not only a technical triumph but also a demonstration of Henkel’s culture of
inclusivity and collaboration. Employees on the shop floor played an integral role in identifying energy-
saving opportunities, suggesting changes to processes, and championing sustainability initiatives.
“From optimising motor operations to developing water-saving strategies, our employees have shown
extraordinary ingenuity,” said Mamatlepa. “Their input reflects a shared commitment to sustainability
and highlights the power of collective action.”
Looking Ahead: A Vision for the Future
While the current installation does not include battery storage, Henkel has plans to evaluate future
investments in energy storage to further enhance energy independence. Additionally, the plant’s energy
monitoring systems will be upgraded to allow for real-time tracking and deeper insights into
consumption patterns, enabling ongoing optimisation.
The Alrode plant’s journey is part of Henkel’s science-based target to achieve absolute scope 1 and
scope 2 emission reductions by 2030. It also aligns with South Africa’s broader energy transition, which
seeks to balance economic growth with environmental stewardship”
“Henkel’s sustainability ambitions extend beyond our own operations,” said Mehmet Yilmaz, Director
Operations and Projects HAT MEA. “We hope our efforts inspire other organisations to take bold steps
toward renewable energy integration and environmental responsibility.”
A Message to the Broader Industry
Henkel’s Alrode solar project underscores the importance of data-driven decision-making and employee
engagement in achieving sustainability goals. The project’s success offers valuable lessons for other
sectors, particularly in navigating South Africa’s energy challenges, including load shedding and rising
electricity costs.
“At Henkel, sustainability is not just a target—it’s a responsibility,” said Veerabhadra Konakalla, Head of
Sustainability, Health and Environment HAT IMEA. “Our solar farm is a testament to what’s possible
when innovation, investment, and collective determination come together. We are proud to contribute
to a cleaner, more sustainable future for South Africa.”
