Wits innovation set to light up lives

Wits innovation set to light up lives

PeCo Power, a new spin-off company, is a home-grown electrical off-grid solution that will radically change lives and impact local communities.

An innovation out of Wits University’s School of Electrical and Information Engineering (EIE) has reached commercialisation stage and will soon find its way into rural and un-serviced communities, with the promise of deep social impact.  

The Personal Consumer grid innovation is essentially a home electrical grid solution, to easily integrate renewable energy sources along with batteries and appliances, for the electrification of households in Africa. This expandable solution ensures that as a household can afford more solar panels or wind generators, batteries or 12 V appliances, these components are easily added to the system, with no need for a trained person to undertake these changes to the system.

Over the past four years, Professor Willie Cronje from the Electric Power Research Group in the EIE has led research into the solution to help address the challenge of electrification for homes that do not have access to a utility power grid.  

Almost one billion people worldwide need off-grid electrification and in Africa this problem is the most severe. In South Africa, at least 10% of the population is unlikely to be connected to the grid in the foreseeable future. This percentage is larger in other African countries.  

The low load demand and dispersed nature of rural settlements (less than 38 people per square kilometer on average in Africa), as well as excessive and rising infrastructure costs, mean that extending conventional electricity networks is no longer viable to many rural areas. At the same time, there is a call to improve health and safety through mitigating the serious fire risk associated with the use of paraffin, candles and wood. In addition, the use of renewable energy sources addresses the need for reducing the carbon footprint.  

“Current off-grid solar home solutions do not accommodate multiple or different types of power sources, and multiple or different types of batteries. They restrict the number of loads i.e. appliances that can be connected. The Wits solution, which works on 12V direct current, can accommodate multiple loads, power and battery components and no central controller, or configuration by a technician is needed: each unit self-configures as the ‘grid’ is expanded in a plug-and-play approach. We are now at the exciting commercialisation stage: after four years in the making, the technology is proven and a company has been formed to bring it to market,” says Prof Cronje. 

Commercialisation  

Wits, through its Technology Transfer Office, assisted Cronje and his team, to obtain a Technology Innovation Agency (TIA) seed-fund grant for part of the research and development and then assisted in starting the commercialisation.  

This led to the establishment of a new spin-off company PeCo Power (Pty) Ltd (“Peco Power”) in October 2019. Umbono Natural Resources (Pty) Ltd (“Umbono”) became the commercial partner because of its strong alignment with Wits’ mission to provide workable solutions to African challenges such as electrification, and further because of its commercial experience, and networks in the independent power producer (IPP) sector. Umbono brings capital and experience to the venture through their hands-on involvement in the development process.

 

 

With the assistance of Umbono, the team has concluded a pilot, and the learning gained from it will be used to finalise the system design so that the technology is commercially ready. PeCo Power has been established, and the intellectual property developed by Wits and Umbono will be transferred to it. This will enable it to continue the joint development and commercialisation process, whilst leveraging the partnership between Wits and Umbono to attract additional investment into PeCo to establish distribution partnerships. 

“In Wits we have found a local, research-grounded and innovation-driven partner who is supportive of our fledgling PeCo Power company. Basing the team at the Goldfields Lab on Wits’ Braamfontein Campus West, will continue to provide the muchneeded technical incubation as we move towards full commercialisation. We are extremely excited to see a home-grown solution, to real community problems, ultimately impact and radically change lives,” says Kerwin Rana, Chief Executive – Umbono. “Umbono is privileged to be a key commercialisation and funding partner in this remarkable Wits innovation, which is squarely aligned with our desire to positively impact local communities.” 

Due to ease of use and scalability, the PeCo Power home grid solution has applications in several markets: 

  • Rural e.g. households and small businesses that are far from the electricity grid; 
  • Urban off-grid e.g. high-density informal settlements; 
  • Camping and off-roading; 
  • Emergency Services such as when NGOs, relief organizations and government organizations require bulk distribution of power, e.g. where a natural disaster has cut off access to electricity. 

Muhammed AswatWits alumni and Engineering Manager at PeCo Power, says: “When I started working with Prof Willie Cronje on this solution as an undergraduate student, I was inspired. We have an opportunity to make a real impact in communities by literally lighting up lives throughout Africa whilst creating jobs and driving local economy through PeCo Power. Mohammed Raees Dangor, PeCo Power-Business Development, and I are the first employees and shareholders of PeCo Power through the Wits’ benefit sharing policy. I am really grateful to Professor Cronje, Wits and Wits Commercial Enterprise for availing this opportunity to us”.
