Energy Provision and Informality in South African Informal Urban Settlements : A Multi-Criteria Sustainability Assessment of Energy Access Alternatives

Sammanfattning: Due to urbanization and governmental incapacity to cope with the consequent increase in demand for housing in cities, more than 10 % of the South African population is living in informal settlements. This group is also growing at high rates, causing settlements in cities to be established in ever less suitable conditions (Gaunt et al. 2012; Wolpe & Reddy 2010). Informal households in locations considered unsuitable for habitation are not sufficiently addressed by current national policies aimed at relieving energy poverty. These households instead resort to buying electricity from their neighbors or stealing from the grid, posing issues of revenue losses, network reliability, safety and affordability, and they also continue to rely on unclean use of fuel for cooking and lighting (Franks & Prasad 2014; Tait 2013). At the same time, alternative ways of providing energy services, such as Solar Home Systems and LPG being tested in such contexts need further examination.  This thesis explores how access to basic energy services can be sustainably provided to informal households that are ineligible for grid electrification, by comparing current and alternative ways of accessing energy services and identifying some barriers and opportunities related to these. The sustainability of the access alternatives is studied using a multi-criteria sustainability assessment (MCSA). This approach incorporates a case study in the Western Cape Province, focused on Cape Town, using semi-structured interviews to explore views and knowledge of stakeholders and experts. The MCSA identifies notable trade-offs of various access alternatives and suggests that off-grid electricity alternatives may provide a short or medium-term solution if provided along with gas for cooking accessed at local convenience stores. The case study further shows that barriers for electrification can be overcome in most cases, providing that there is political will at the local level to do so. At the same time, it is shown that the current focus on electricity is limited in its success of providing access to basic energy services. It is suggested that sustainable implementation of alternatives to grid electricity is likely to depend on a range of factors, including political will, policy framework, funding and allocation of subsidies, the model of service provision, as well as social dynamics. The case study also indicate that non-government initiatives may be necessary in some cases, both to overcome political inertia and to gain social acceptance among households. In conclusion, this study supports the suggestion that governmental efforts aimed at access to energy services, as opposed to supply of electricity, may be more effective in meeting basic needs. It also suggests that close cooperation between various government levels, as well as non-government actors and the local community is crucial to sustainably meeting these needs. As this work was limited both in time and scope, further studies should apply and/or study possible models of providing access to basic energy services, using findings from this study as a starting point.
