Novel research into using renewable energy in off-grid informal settlements in South Africa has won the Chair’s Prize at the prestigious Newton Prize awards.
Many of the 1.25 million households in informal settlements rely on burning paraffin or wood to cook and provide light and warmth in their homes. Not only do these methods of energy production create health and safety hazards, but they also limit the economic and educational opportunities of the people living in these settlements.
A research team jointly led by Dr Jiska de Groot, senior research fellow at UCT’s African Climate and Development Initiative, and Dr Federico Caprotti of the University of Exeter in the UK, will use the £500 000 (R10.2 million) award funding to provide workable solutions to address these challenges.
The team has developed a new approach to providing power to these communities. Titled “Urban transformation in South Africa through co-designing energy services provision pathways”, the project focuses on providing clean, safe and reliable energy to those who live in informal settlements.
“Our project is trying to solve the global challenge of access to affordable and clean energy for all. Energy is an enabler of development. The lack of energy doesn’t just create health impacts, but also huge inequalities and opportunities for people to develop,” said De Groot.
To overcome the challenges caused by lack of access to energy, as well as those posed by policy, legal and jurisdictional barriers, the team developed a novel approach to electricity supply in off-grid areas. The solution involves using renewable energy in combination with sustainable, pay-as-you-go business models.
Having identified off-grid informal settlements in Cape Town, the team worked with community representatives, non-governmental organisations and UK energy organisations to address the challenges in each settlement.
The researchers devised a system that paired solar-powered minigrids with app-based business models to provide energy for multiple uses. This led to the testing of the minigrid in informal settlements in Cape Town, where the team was able to produce electricity that was up to 40% cheaper than that from current suppliers.
“Safe and stable electricity through solar minigrids can contribute in a significant way to providing adequate and safe housing. This is because solar microgrid-delivered electricity enables the provision of safe lighting and safe electricity connections, which avoids the need to have illegal, unsafe electricity connections to the national grid.
It also avoids the need to burn candles or other combustible materials for indoor lighting, reducing fire risk,” she said.
The team now wants to focus on providing electricity for refrigeration in these off-grid communities.
