- Description: This paper seeks to contribute to the solutions of some of the challenges faced within Eskom Generation with regards to sustainably supplying electricity to South Africa and the neighbouring countries – the approach used in this paper is to improve quality within the maintenance sphere, considering quality workmanship and high quality standard equipment normally increases reliability and availability – With an increased reliability and availability, there is a strong likelihood that Eskom equipment will be able to produce electricity sustainably. Furthermore, the research found that there are a number of aspects to incorporate into the business in order to have a well-rounded quality system within the business. The Maintenance department would need to have a strategy that is founded on the type of assets and life of the assets, the department needs to have a computerised maintenance management system that integrates with other relevant departments such as Finance who needs to guarantee correct budgets for the respective maintenance plans, Stores who will have to ensure correct stock levels to carry out maintenance works, and Procurement who will need to know which services and goods to prioritise among purchase requisitions and purchase orders. HR also plays an important role, as per the research, when it comes to training and development that can improve the abilities of the employees to provide a speedier and accurate service when he/she is more competent; Maintenance management along with engineers then have the crucial role of marrying these aspects to provide the maintenance philosophy for the business that is most suited to the equipment in the plant. If any of these aspects are missing, it becomes a bit challenging to have a complete quality result. Some of the tools that the research considered are TQM and TPM with a strong focus on WM pillar. WM provides for equipment to be part of a Preventative Maintenance schedule to ensure all equipment is properly cared for, and to ensure history and trends are captured for future planning. Even though this research was limited to assess Tutuka EMD strategy, the above principles are applicable and helpful for maintenance departments on a global scale, and not only limited to power industries.

- Description: A key economic issue for government is the ability to effectively match electricity supply to electricity demand, because of the substantial economic losses in the case of where there is too little supply, or the waste of scarce resources where there is too much supply. In the case of South Africa, this issue, the importance of which was highlighted by the power shortages and associated “rolling blackouts” experience in 2008, has led to the creation of the Integrated Resource Plan (IRP) as a means to decide how energy policy will be developed. Recently, however, the IRP 2010 and its subsequent 2013 and 2016 (draft) updates have been criticised as being too optimistic in regards to their projections of economic growth and electricity demand, making the recommendations in these documents to be flawed. Using monthly data from January 1990 to May 2017, together with Autoregressive Distributed Lag (ARDL) bounds testing for cointegration, this paper measures changes in the elasticity of electricity demand as a result of the massive price hikes over the past decade. Thereafter, the implications of changed electricity as well as possibly lower Gross Domestic Product (GDP) growth in the future for forecasts of possible future demand for electricity are examined. From these revised forecasts, it is possible to make appropriate recommendations in regards to electricity supply policy for South Africa including what possible energy mix is needed as well as the requirements for creating new supply to meet possible future demand. It is concluded that future electricity demand is likely to be much lower than forecast in the IRP 2010 and IRP 2013 documents. The degree of uncertainty in electricity demand growth suggests that large-scale increases in supply capacity taking years to construct, such as coal or nuclear, should be avoided. Small, incremental increases in supply that are able to come on stream swiftly, such as gas, solar and wind power, are likely to be more appropriate for meeting South Africa’s future needs.

- Description: The electric power policies in Nigeria and South Africa are considered the governments’ intention to provide quality and affordable electricity to the people. A comparative study on the electric power policies focuses on the similarities and differences in the policy approaches, the policy issues that affect electrification, and the impact of the policy issues in achieving the goal of universal access to quality and affordable electricity power in both countries. The methodological approach allows for an in depth textual study on the electric power policy documents in both countries. In Nigeria, the government intends to address the massive demand-supply imbalance and achieve the goal of electrification through reforms that focus on private sector-led growth in the sub-sector. In South Africa, the identification of electrification as a public problem by the post apartheid government leads to an integrated policy framework that focuses on balancing economic concerns with social and environmental considerations. The study identifies electricity provision as a social welfare responsibility of the governments in both countries and examines the policy issues in the context of public welfare. In Nigeria, the policy issues are found to be self serving and not in line with sustainable public interest, given the socio-economic challenges. As a result they, exert less impact on achieving the goal of universal access to quality and affordable electricity in the country. In South Africa, good governance in the sub-sector has enabled the identification of policy issues in line with sustainable public interests of social equity, poverty alleviation and environmental sustainability; and government using public administration agencies to play a key role in service delivery. Recommendations of the study mainly derive from the South African experience on electrification, and are intended to offer some policy-lessons to Nigeria in the sub-sector. The study contributes to new knowledge in the discipline of public administration by opening up new vistas for a comparative analysis of electric power policy issues in both countries in the context of public welfare. Besides, a comparative study on electrification in Nigeria and South Africa from a policy angle contributes to the existing knowledge base in the discipline.

- Description: There is growing interest in research and development activities on biomass gasification technologies as an alternative to fossil fuels technologies. However not much has been done in terms of technology transfer, particularly in under-developed and developing countries such as South Africa. This is mainly because of the lack of resources such as funding. Most parts of the under-developed and developing countries fall within rural areas and semi-urban centers, which are endowed with biomass resources. South Africa has a number of sawmill operators who generate tons of biomass waste during processing of timber; the large proportion of this is burned in furnaces as a means for waste management while a very small proportion is collected and used by people in rural areas for cooking their food. The majority of people in rural areas of South Africa are either unemployed or cannot afford the current energy services. The main aim of this research was to establish the viability of electricity generation for community economic development through biomass gasification, specifically using the locally designed System Johansson Biomass Gasifier™ (SJBG), and to establish the efficiency of the gasifier and associated components with a view of developing strategies to enhance it. The study established the technical and economic feasibility of using the SJBG to generate low-cost electricity for community empowerment. The study also developed strategies to improve the particle collection efficiency of the cyclone. In addition to this, a low-cost gas and temperature monitoring system capable of monitoring gas and temperature at various points of the gasifier was developed. The system was built from three Non- Dispersive Infrared gas sensors, one Palladium/Nickel gas sensor and four type K thermocouples. The study also investigated the impact of fuel compartment condensates on gasifier conversion efficiency. This is an area that has not yet been well researched since much has been done on energy recovery using combined heat and power applications that do not utilize the energy in condensates because these are produced in the gasifier and drained with chemical energy stored in them. The study established that the condensates do not have a significant impact on efficiency.

- Description: The objective of this research is to assess the impact to the Nelson Mandela Bay Municipality due to ongoing Electricity Distribution Industry Restructuring in South Africa as directed by the Electricity Distribution Industry Holdings on behalf of the Department of Minerals and Energy’s adopted Electricity Distribution Blue Print Report of 2001. Literature review of scholarly literature was conducted on privatisation of public utilities that offered an international perspective on experiences of other countries that has undergone similar experiences of restructuring of public assets, the state of Electricity Supply Industry in South Africa with the demonstration of structural financial and physical flows and historical background of the restructuring, proposed future model and strategic plans to achieve the future goals. Research methodology and design was done through combination of the four-research types classification in their order of sophistication except the predictive research, namely exploratory, descriptive, and analytical or explanatory researches with a further inclusion of deductive research. The compilation of data through questionnaires was also employed. Perceptions on internal impact to the NMBM due to electricity services restructuring were solicited from the sample of the top management of the NMBM, the intention was to ensure the economies of scale, greater transparency and competition in terms of service delivery were sustained during and beyond Regional Electricity Distributor establishment. Financial position of NMBM as a critical instrument for its progress has to be protected to ensure it fulfils its constitutional development mandate. The findings of the research were in strong support of ensuring operational financial viability; to meet the legitimate employment, economic and social interest of all employees; development and implementation of change management strategies; and NMBM assuming leading role in the process.
