Access and affordability of electricity in developing countries
(Elsevier, 2011) Winkler, Harald; Alam, Mozaharul; Rahman, Atiq; Mwakasonda, Stanford; Simões, André Felipe; Rovere, Emilio Lèbre La
A key objective of developing countries is to provide affordable access to modern energy services in order to support economic and social development. The paper presents a number of arguments for why and in which way energy access and affordability can play a key role in national development programs and in achieving the Millennium Development Goals. Approaches for measuring accessibility and affordability are presented, drawing on case studies of Bangladesh, Brazil, and South Africa, countries with different rates of electrification. Affordability of using electricity is examined in relation to the energy expenditure burden for households and time consumption. Conclusions focus on lessons learned and recommendations for implementing policies, instruments, and regulatory measures to tackle the challenge of affordability.

Building bridges to 2020 and beyond: the road from Bali
(Taylor & Francis, 2007) Winkler, Harald; Vorster, Shaun
What would the shape of a realistic, yet ambitious, package for the climate regime after 2012 look like? How do we obtain a package deal starting in Bali but building bridges to a post-2020 climate regime? A fair, effective, flexible and inclusive package deal has to strike a core balance between development and climate imperatives (mitigation, adaptation, dealing with the impacts of response measures, technology transfer, investment and finance) to create bargaining space and establish a conceptual contract zone. Within a continuum of possible packages, two packages in the contract zone are identified: ‘multi-stage’ and ‘ambitious transitional’. The latter is ambitious, combining domestic cap-and-trade for the USA, deeper cuts for Annex B countries, and quantifiable mitigation actions by developing countries. It is transitional as a possible bridge to a more inclusive regime beyond 2020. Multi-stage is defined around mechanisms by which countries move through increasingly stringent levels of participation, and must be based upon agreed triggers. Our assessment of political dynamics is that multi-stage is not yet in the political contract zone. Key to this is the absence of a ‘trigger from the North’, in that the largest historical emitter must act earlier and most decisively. But progress will also depend on continued leadership from Annex B countries, as well as more proactive, incentivized leadership in the South. Agreeing on the transitional stage is the critical next step in the evolution of the climate regime. Negotiating any package will require an institutional space for bargaining, political leadership and trust, and a clear time-frame.

Costing a 2020 target of 15% renewable electricity for South Africa - Final Draft
(Energy Research Centre, University of Cape Town., 2008) Marquard, Andrew; Merven, Bruno; Tyler, Emily; Hagemann, Kilian
This study explores the implications of a renewable energy target, with South Africa setting and achieving 15% of electricity generated from renewables by 2020 We report the effects of 15% renewable electricity on the total cost of electricity production, investment in electricity infrastructure, and national greenhouse gas emissions. Achieving such a target will pose institutional, financing and policy challenges and we consider several options. The two most promising technologies for South African conditions are wind and solar thermal electricity.

Does access to electricity enable the uptake of small and medium enterprises in South Africa
(Energy Research Centre, University of Cape Town., 2007) Prasad, G; Dieden, S
South Africa increased its electrification coverage from 36% to over 70% in the last 12 years. Predominantly poor areas, to which service provision was neglected in the past, got access to electricity. The socio-political benefits of the national electrification programme are documented, but the economic benefits which are generally assumed have not yet been analysed in detail. This paper explores how far existing surveys provide data on the impact of electrification on the uptake of small and medium enterprises or self-employment among households. We analyse nationwide household survey data from 1995 to 2004. Variation in electrification rates among households seems correlated with SMME uptake, but the nature of the association varies across regions and appears to display differing trends over time. A trend of positive correlation of SMMEs and electricity access in poor rural areas does seem apparent.

Draft policy framework for efficient water use in energy production.
(Energy Research Centre, University of Cape Town., 2014) Madhlopa, Amos; Keen, Samantha; Sparks, Debbie; Moorlach, Mascha
South Africa faces imperatives to secure a supply of clean water and to protect water resources, as well as to provide a secure supply of energy. Over and above the mandates of ensuring clean water provision and of improving the coverage and security of a reliable energy supply, the government faces challenges of reducing poverty and unemployment, and of ensuring sustainable development. In order to meet these challenges, the national government has developed a set of progressive policies. Harmonisation of these policies is itself a considerable challenge.

Economics of climate change: context and concepts related to mitigation
(Energy Research Centre, University of Cape Town., 2009) Winkler, Harald; Marquard, Andrew; Tyler, Emily; Visser, Martine; Brick, Kerri
Climate change is increasingly seen as not only an environmental issue, but a deeply economic one. ‘Climate change presents a unique challenge for economics: it is the greatest and widest ranging market failure ever seen’ (Stern Review 2006). Markets are failing to put a price on the emissions of greenhouse gases, passing the costs on to society as a whole.

Economy-wide Modeling: An input into the Long Term Mitigation Scenarios process
(University of Cape Town. Energy Research Centre, 2007) Pauw, Kalie
The objective of this analysis is to develop a better understanding of the likely impact that various mitigation options may have on the economy in terms of GDP, employment and household welfare. As noted in the introduction, outcomes of three mitigation scenarios, Start Now, Scale Up and Use the Market, are evaluated. These mitigation scenarios are combinations of different degrees of energy efficiency that can be achieved, structural shifts in energy output mix and, in the case of the latter scenario, economic instruments used to reduce emissions. Results are compared in comparative static fashion against a ‘business as usual’ reference case called growth without constraints (GWC). This remains a scenario analysis, and by no means can we claim that results are necessarily an accurate reflection of the true outcome. Given the long time horizon and the multitude of economic variables and parameters that may change over time and impact on each other, not to mention factors external to the South Africa economy that cannot be controlled, it is unwise to have too much confidence in results. However, the exercise remains useful. We are upfront about the limitations, the assumptions and the methods used to arrive at results, and given these, the scenario analysis provides a useful starting point for policy discussions around possible outcomes under various different mitigation scenarios for South Africa.

Electricity supply options, sustainable development and climate change priorities: case studies for South Africa
(Magnum Custom Publishing, 2007) Winkler, Harald; Mwakasonda, Stanford; Garg, Amit; Halsnaes, Kirsten; Mukheibir, Pierre
This report summarizes the results of the Projecting future energy demand: Balancing development, energy and climate priorities in large developing economies project that has been managed by the UNEP Risø Centre on behalf of UNEP DTIE. The project, sponsored by UNEP, is a partnership between the UNEP Risø Centre and centers of excellence in South Africa, China, India and Brazil. The focus of this report is on the energy sector policies that mainstream climate interests within development choices. The country study results for future energy and environment projections that are included in this report are backed by intensive economy-energy-environment modeling by the Energy Research Centre at the University of Cape Town, South Africa, wherein general scenario analysis of the energy sector explores some policies in more depth. The report argues that starting from development objectives is critical to mitigation efforts in developing countries. Instead of defining local benefits as ancillary to mitigation, reductions of GHG emissions should be seen as the co-benefits of policies that drive local sustainable development. A development-focused approach seems more likely to be implemented than the imposition of GHG targets by the international community—especially as South Africa has adopted development targets such as the Millennium Development Goals and promoted the Johannesburg Plan of Action.

Energy and the World Summit on Sustainable Development: What next?
(Elsevier, 2005) Spalding-Fecher, Randall; Winkler, Harald; Mwakasonda, Stanford
Given the importance of energy issues to sustainable development, energy was a priority issue at the World Summit on Sustainable Development in August 2002. The objective of this paper is to examine the outcomes of the Summit on energy, and to assess them against proposals to address the lack of access to modern energy and the need to move toward a cleaner energy system. We find that lack of political leadership from key countries prevented agreement not only on targets for renewable energy, but also on a programme to promote access. The achievements of the Summit were limited to enabling activities such as capacity building and technology transfer, rather than substantive agreements. While WSSD put energy higher on the agenda than before, no institutional home or programme to take the issues forward has emerged. This therefore remains a critical challenge to be addressed. Achieving this broad goal will require building a coalition to promote cleaner energy, and committing resources to programme for energy access. Based on analysis of proposals and the negotiations, we propose several key areas where progress is still possible and necessary, including: shifting more international public and private energy financing toward access investments and cleaner energy investments, advancing regional approaches to access and renewable energy targets, and a range of mechanisms to strengthen institutional capacity for integrating energy and sustainable development.

Energy Development and Climate Change: Decarbonising Growth in South Africa
(University of Cape Town, 2007) Winkler, Harald; Marquard, Andrew
This paper presents a case study of human development and climate change in South Africa. It starts by outlining the key development challenges that the country faces and the history of recent responses in development policy. Section 2 hones in on the energy sector, providing a brief profile of the sector contributing most to greenhouse gas (GHG) emissions. The implications of South Africa’s ‘minerals-energy complex’1 for its GHG emissions profile are examined in section 3. Section 4 discusses the context and development of South African climate change policy, and examines implementation progress to date. The final section of the paper begins with a summary analysis of key mitigation options in energy efficiency, changes in the fuel mix and structural changes. Section 5 then examines the key constraints facing the implementation of such options, before concluding with possibilities for international cooperation to contribute to sustainable development and mitigation in South Africa.

Energy policies for sustainable development in South Africa
(Elsevier, 2007) Winkler, Harald
This paper summarises the results of a study that analysed ways of making South Africa’s future energy development more sustainable. The South African economy is comparatively energy-intensive, with total primary energy supply of 11.7 MJ per US$ of GDP on a purchasing power parity basis, compared to 7.9 MJ/$ for Asia and 6.7 MJ/$ for Latin America. Moreover, the high dependence on coal makes the country also very carbon-intensive, with energy related CO2 emissions of 6.7 tonnes per capita, comparable to the OECD average of about 11 tCO2 /cap., and far higher than the non-OECD average of 1.7 tCO2/cap. Important policy initiatives are already under way to improve energy efficiency as well as the share of renewable energy. The impact of different energy policies, including alternative technologies for both supply and demand up to 2025, were analysed using the Markal model, a least-cost optimising tool. The reference case is close to the government’s Integrated Energy Plan, with CO2 emissions increasing from 337 million tonnes (Mt) in 2001 to 591 Mt in 2025. A cost-effective renewable energy policy scenario would increase the renewable electricity generation from 2,000 GWh in 2001 to almost 18,000 GWh in 2025, with significant contribution from solar thermal and biomass cogeneration technologies. Energy efficiency can make a substantial contribution, especially in industry. The combination of measures would reduce total energy system costs by 16 billion rands ($ 2.2 billion) and CO2 emissions by 770 Mt, each over a 25-year period. The policies analysed here can therefore contribute both to sustainable development and to climate change mitigation.

Energy, water and climate change in Southern Africa: what are the issues that need further investment and research?
(Energy Research Centre, University of Cape Town., 2012) Prasad, Gisela; Boulle, Michael; Boyd, Anya; Rahlao, Sebataolo; Wlokas, Holle; Yaholnitsky, Ivan
Regional climate change projections in Southern Africa, based on GCMs comparing 2080-2099 to 1980-1999, indicate that global warming will most likely lead to greater than the global annual mean temperatures for all seasons, 3.1°C for summer warming and 3.4°C for winter warming (Christensen et al, 2007). Warming in Southern Africa will lead to increasing rainfall intensities, decreasing frequencies of low intensity (soft soaking) rainfall and longer dry period between rainfall events. This will result in more severe draughts, floods and heatwaves, which will lead to greater food insecurity. In historic times, draughts and floods had already major impacts on Southern African populations. Around 1200 to 1500, droughts led people to abandon settlements in the Kalahari Desert. The Lifaqane wars, starting in about 1815, were characterized by a 25-year period of famine and violent conflict between peoples in Southern Africa. During the 1991-1992 draught, 20 million people in the region (15% of SADC population) needed food relief (Dejene et al 2011). Many parts of Southern Africa face two critical resource constraints on development, namely energy and water. Energy and water are closely linked at different levels and scales. Water drives the turbines of hydroelectric power plants. Processing of coal and cooling in thermal and nuclear power plants requires water and energy is required to lift, treat and distribute water. Even at the household level, we observe water-energy linkages. When using water-saving showerheads, for example, we not only save water, but also electricity for heating the water. This complex interconnection is called the water-energy nexus. At the same time, coal-based power plants emit large amounts of greenhouse gases (GHGs) into the atmosphere, contributing to climate change and climate variability which then leads to floods and droughts. In times of drought little water flows into hydroelectric dams, affecting electricity generation. For rural communities the greater frequencies and severity of droughts and floods caused by climate change leads not only to crop failure and subsequent hunger but also interferes with water supply technologies when, for example, the water levels in boreholes rise or fall beyond the specification of the pump. Thus climate change critically impacts the water-energy nexus. The International Development Research Centre (IDRC) in Canada commissioned the Energy Research Centre (ERC) at the University of Cape Town to assess the water-energy nexus in the context of climate change. ‘The goal of the exploratory project is to analyse the way energy and water services can be combined and improved to enhance resilience and adaptive capacity of communities to climate variability and change’. After an introduction to the water-energy nexus in Southern Africa (Chapter 1) and a brief review of the four countries studied as well as climate change scenarios for the Southern African region (Chapter 2), the study reports on the following four major research topics identified by the Southern African team: 1. The state of integrated planning of water and energy resources in the context of climate change (Chapter 3). 2. Opportunities and barriers for renewable energy technologies for rural water services in Namibia, Botswana and Mozambique (Chapters 4 and 5). 3. The water-energy nexus in policies of South Africa (Chapter 6). 4. An investigation of water supply adaptation technologies and strategies in a case study from Lesotho (Chapter 7). The assessment is based on secondary data through a cross-disciplinary desktop study, discussions with experts and two workshops. The countries covered in this report are Botswana, Lesotho, Mozambique, Namibia, and South Africa.

Estimating greenhouse gas emissions associated with achieving universal access to electricity in South Africa
(Energy Research Centre, University of Cape Town., 2012) Tait, Louise; Winkler, Harald
Climate change, energy security and achieving universal electricity access for all households are all pressing issues that South Africa must address. These objectives need not be trade-offs, however, and achieving electricity access for the poor does not justify the building of large coal-fired power stations or threaten South Africa’s climate change objectives. This paper estimates the electricity demand from the residential sector to 2020 resulting from universal access, and finds that electricity for low-income households would constitute only a small addition to total electricity demand and would represent only a minor portion of output from the coal-fired power station, Medupi. Furthermore, emissions from the additional electricity consumed by newly connected households would have a negligible impact on South Africa’s emissions profile.

Feito no Brasil? Made in South Africa? Boosting technological development through local content requirements in the wind energy industry
(Energy Research Centre, University of Cape Town., 2013) Rennkamp, Britta; Westin, Fernanda Fortes
How can local content requirements (LCR) boost technological capability for renewable energy? This paper investigates the implementation of LCR in the wind energy in Brazil and South Africa. Brazil tried to grow a local wind industry requiring 60% domestic content in each installation since 2004. South Africa demands up to 45% domestic content in its recent program. The benefits of these requirements are heavily debated. The rationale behind LCR is that governments in developing countries intend to stimulate jobs in new industries and to accelerate technological development. This market intervention imposes a barrier for international manufacturers, as local manufacturing can push up the technology prices. Based on evidence from Brazil and South Africa, we find that LCR fall short as a single technology policy instrument. The Brazilian case shows that LCR incentivized the domestic production of low and medium technology content. These are the heavy parts, such as the towers, which are difficult to transport. Recently, parts of the nacelle, hubs and blades have increasingly been manufactured locally. High technology-intensive components, however, continue to be imported. Boosting local industries requires not just restrictive measure such as content requirements but, more importantly, it requires active support of technological capability.

Green certificate trading
(Energy Research Centre, University of Cape Town., 2009) Brick, Kerri; Visser, Martine
This paper proceeds as follows: Section 2 briefly outlines the policy instruments available for the promotion of renewable energy sources, while section 3 discusses green certificate trading in more detail, including the green certificate market in South Africa at present. Section 4 describes the international implementation of renewable energy support mechanisms. The lessons learnt from this experience in terms of design suggestions for the development of a South African TREC framework are detailed in Section 5. Also from international experience, Section 6 provides a comparison of a feed-in tariff scheme and a quota obligation system combined with tradable green certificates. Finally, the interaction between emission trading schemes and renewable energy promotion systems are outlined in Section 7.

Local employment through the low-pressure solar water heater roll-out in South Africa
(Energy Research Centre, University of Cape Town., 2013) Wlokas, Holle Linnea; Ellis, Charlotte
In February 2013, the United Nations Secretary-General’s High-Level Panel of Eminent Persons on the post-2015 development agenda failed to identify climate change as a priority issue (United Nations 2013). The defined framing questions for the panel’s work and the most recent announcement highlight sustainable growth with equity, wealth through management of natural resources and partnerships - but not the detrimental impact of climate change on development (Field 2013). This shortcoming is a reflection of the current discourse. Even though changing, climate change and development are still located in two different camps. Although much work has gone into bridging this gap by potentially aligning policy agendas, the challenge to achieve integration of climate and development objectives is still obvious on the ground (Rennkamp 2012). Solar water heating in South Africa is one such on-ground example which, when investigated thoroughly, presents a learning opportunity.

Long Term Mitigation Scenarios: Strategic Options for South Africa
(Department of Environment Affairs and Tourism, 2007) Scenario Building Team
The focus of this document is mitigation: if South Africa takes the decision to mitigate, then this document addresses how to determine the options, the emissions reductions achieved by these options, and the attendant costs of each option. How, then, is South Africa to grow and develop in order to reduce poverty, while at the same time retooling its economy in order to reduce its greenhouse gas emissions?

Low carbon development and poverty: exploring poverty alleviating mitigation action in developing countries
(University of Cape Town, 2012) Wlokas, Holle; Rennkamp, Britta; Torres, Marta; Winkler, Harald; Boyd, Anya; Tyler, Emily; Fedorsky, Catherine
Climate change and poverty mostly fall into the adaptation category in the current research literature and relevant policy-making. The strong connection between poverty and adaptation rests on the assumption that poor countries produce only low carbon emissions. They will also be most affected by the impacts of climate change. Therefore, efforts on poverty and climate change concentrate mostly on adapting to the consequences of climate change. If we acknowledge current findings of poverty research, we find that this separation between mitigation and adaptation does not hold anymore. Recent research suggests that poverty demographics have changed between 1990 and 2010. The majority of the poor nowadays live in middle-income countries, and not only in low-income countries. Emissions in middle-income countries increase, while their governments try to reduce emissions in the long term without jeopardising socio-economic development. Climate change presents a threefold policy challenge for middle-income countries. They need to: i) design mitigation actions in such a way that they contribute to alleviate poverty; ii) reduce emissions, helping to slow global warming in a way that does not compromise the competitiveness of their economies, because without collective action by all, the costs of inaction affect mostly the poor; and iii) prepare to adapt to the unavoidable consequences of climate change. The paper unpacks the linkages between low-carbon development, mitigation and poverty in middle-income countries (where the majority of the poor live). Most middle-income countries pursue carbon-intensive development paths and will need to mitigate emissions towards low-carbon development paths. How can mitigation actions contribute to poverty alleviation? An explorative analysis of mitigation actions in five middle-income countries shows that mitigation has moved on the political agendas over the past five years. Yet, these efforts are not necessarily linked with poverty alleviation instruments. Most mitigation action can have positive and negative poverty effects. Their impacts depend on an adequate pro-poor policy mix.
