How the sustainability transition in energy is transforming the built environment of South African cities

Abstract

South Africa is undergoing a sustainability transition (ST) in its energy sector as part of its broader move towards a lowcarbon future. Past studies of the nascent ST using a multi-level approach have already proven obsolete after strong resistance from the incumbent energy regime almost derailed the fledgling renewable energy (RE) industry. After initially going to ground and contracting, the industry re-emerged strongly in South Africa’s cities, mostly in the form of rooftop solar photovoltaic (PV) systems. This study applies an integrated approach utilizing the Multi-level Perspective (MLP) to trace the current ST trajectory, whilst employing the Technology Innovation Systems (TIS) framework as a focal lens, recently adapted to the follower country context, to empirically investigate system development in the solar PV TIS. A survey was conducted to assess the drivers and challenges facing consumers of solar PV technology in cities, the results indicating that the rapid growth in distributed embedded generation (EG) was sparked by recent tax incentives and not the introduction of Feed-in Tariffs (FIT) offered by city municipalities. Whilst the RE sector and solar PV market have grown through consumer demand for EG, they still face resistance from the existing energy regime, needing further development in policy and regulation in order for South Africa’s ST to support a more complex web of distributed and embedded generation, mostly underpinned by RE technologies.
