As the global community marks World Engineering Day for Sustainable Development, Aurex Constructors reflects on more than 13 years of delivering photovoltaic plant installations that support South Africa’s shift toward cleaner energy.

The company has steadily expanded its role in the renewable sector, combining practical engineering expertise with a focus on sustainable innovation. In March 2023, Aurex established a dedicated engineering division to strengthen technical capability and advance new solutions. Aligned with this year’s theme, smart engineering and digitalisation remain central to building resilient infrastructure and enabling progress across energy and industry.
Proclaimed by Unesco in 2019 and celebrated annually on 4 March, World Engineering Day recognises the vital contribution engineers make toward achieving the United Nations Sustainable Development Goals (SDGs). The 2026 theme places sustainability and innovation firmly at the centre of global development, principles that are deeply embedded in Aurex Constructors’ renewable operations.
Over a decade of renewable leadership
For over 13 years, Aurex Constructors has been at the forefront of South Africa’s renewable energy journey. Since its first project in 2012, the company has installed more than 1.3 GW of clean photovoltaic (PV) power and constructed 16 solar plants, positioning itself as a trusted partner in large-scale renewable delivery.

Herman Buhrmann, Operations Director: Renewable Energy Solutions at Aurex Constructors, says the company’s fully integrated EPC model sets it apart in an increasingly competitive market.
“In our renewables division, we engineer in-house, procure in-house, and construct with our own teams. That integrated capability gives us a significant advantage in terms of quality control, efficiency, and interface management. When engineering and construction sit under one roof, decisions are made faster. Problems are solved in the interest of the project, not in isolation.”
Operating across oil and gas, chemicals, mining and metals, thermal power and renewable energy, Aurex Constructors has strategically evolved its renewable offering to meet growing market demand. In recent years, the company expanded into full turnkey EPC solutions in renewables, establishing a robust internal engineering department to complement its construction expertise.
Engineering built from the ground up
Unlike providers that price projects per megawatt, Aurex Constructors develops each plant from first principles. Every site presents unique topographical, geotechnical, and grid-connection challenges.
“Although PV technology may be similar, every plant layout is different,” explains Buhrmann. “We develop each solution from the ground up, based on client requirements and what we believe is the best technical outcome for long-term reliability.”
Regulatory reforms, rising electricity tariffs, and the removal of generation caps have accelerated private renewable investment in South Africa. Businesses increasingly seek long-term price certainty through power purchase agreements (PPAs), alongside sustainability commitments and energy security.
Battery Energy Storage Systems (BESS) are also transforming the landscape. “Battery storage enhances energy stability and reliability,” notes Buhrmann. “Where conventional supply may fluctuate, renewable plants typically commit to very high availability levels. Storage allows us to flatten generation profiles and provide greater certainty to off-takers.”
Building the next generation of engineers
Central to Aurex Constructors’ success is its in-house engineering capability, led by engineering manager Natie Odendaal. Over the past three years, the department has grown rapidly, incorporating multidisciplinary expertise across electrical, civil, mechanical, and structural engineering.
“Renewable energy projects demand cross-disciplinary thinking,” says Odendaal. “Our engineers collaborate across civil and electrical design to optimise land use, reduce costs, and improve constructability. We also integrate the latest digital tools to enhance quality and efficiency.”
As climate patterns shift, engineering resilience has become essential. Increased rainfall in certain regions, for example, has required advanced stormwater management and erosion-control designs to ensure 25- to 30-year plant lifespans. Beyond project delivery, Aurex Constructors is committed to skills development and closing South Africa’s engineering age gap.
Why facilities management is critical to smart buildings and safer operations
“We have identified a significant gap between older and younger engineers in the market,” explains Odendaal. “Our focus is to mentor young professionals, support professional registration, and create structured development plans so that knowledge is transferred effectively. We are investing in engineers who will power Africa’s future.”
Buhrmann adds that opportunity and growth are key drivers for retaining talent. “People want to broaden their skill sets and be part of something meaningful. As our projects grow in scale and complexity, so too do the opportunities for our engineers. We believe strongly in the future of this country and in the role renewable energy will play in that future.”
Empowering a greener tomorrow
Aurex Constructors continues to expand its footprint across South Africa, and increasingly into the broader African market. On World Engineering Day, the company reaffirms its commitment to innovation, sustainability and excellence in delivery. Engineering is not only about infrastructure. It is about enabling energy security, supporting economic growth and building resilient communities for generations to come.
As the renewable sector evolves, Aurex Constructors remains dedicated to providing flexible contracting strategies, whether as EPC contractor, sub-EPC partner or construction specialist, delivering tailored solutions that meet the unique needs of every client.
