Pendulum Energy launched back in 1977 when we concentrated on the fledgling Television industry.

In those days, we developed several groundbreaking systems for the language dubbing industry, which simply did not exist at the time. Chief Design Engineer, Johan Theron, is still with us and continues to produce his brilliant designs – this time for the Energy Sector.


Meet Johan Theron

Johan qualified for the National Technicians Diploma from the College for Advanced Technical Training in 1972 and started his brilliant career as a designer of creative and inspiring electronic systems with the Anglo-American Electronics Laboratories. Many of his patented designs are still in daily use in South African mines. Later, he designed and developed groundbreaking systems for the language dubbing industry, which simply did not exist at the time. Since turning to the energy sector more than fifteen years ago, he produced, among others, the highly successful PowerGuard range of products that address automated peak demand management. Johan oversees everything technical in the company.

Meet Hannes Roets

Hannes studied at the Aeronav Academy, Flight Safety International, Pilatus Academy, and the South African Air Force College, earning the highest professional qualifications in South Africa as well as the USA. Following a dual career in business and aviation, he teamed up with school friend Johan in 1977 and established what is the foundation of our company today. He specialises in energy efficiency and demand management and has extensive experience in this sphere. His focal point is on business making actual and permanent energy efficiency and conservation improvements.  Getting the most out of energy usage and stopping needless waste is his top priority.

This picture of a Tiger Moth has absolutely nothing to do with anything on this website. One of our directors just happens to be particularly fond of this painting of his Tiger that he flew for 28 years.
