- Description: M.Ing. , This dissertation deals with the implementation of a Reliability Basis Optimisation Process for Eskom’s fossil fired Power Stations. This study comes about as a result of the situation that Eskom currently finds itself in. Eskom currently has a generating capacity of 41 000MW. It supplies 95% of South Africa’s power requirements and 45% of Africa’s power requirements. With the unprecedented economical growth that South Africa has experienced in the last five years, coupled with the economic recession of 2008/2009, Eskom has found itself in a precarious position in terms of power delivery. Eskom’s request for a 45% tariff increase in its Multi Price Determination (MYPD2) application to NERSA was turned down and a figure of 25% was awarded. Eskom’s current reserve margin is currently lies as less than 10%. With the funding restrains it now becomes difficult to replace machinery as it fails. The focus now shifts of carrying out effective maintenance. Eskom established the Asset Management Department with a view to ensure that the right maintenance was carried out. Within the Asset Management Department the Reliability Basis Optimisation (RBO) Process was established. The aim of the RBO stream is to improve the reliability and availability of the fossil fired Power Station. This dissertation looks at how the RBO process was developed and rolled out to the Power Stations. It also gives a brief overview of the Asset Management Improvement process to which the RBO process is the backbone.

- Description: M.Ed. , Eskom has a programme called `Electro-Wise'* which is described as addressing the problem of the use of electricity in the community. Such a programme, it is claimed, educates people to use electricity in a cost effective manner and as such empowers people to monitor their electricity use and take necessary precautions on the safe and effective way of using electricity. The study seeks to challenge this view on the community education grounds that it tends to take for granted the process of educating the community (in an empowering manner) for empowerment. Furthermore, it undermines the method suitable for approaching adult learners * who have to be taught in an informal setting. A brief introduction of what community education entails and what `Electro-Wise' would be if it were based on the theories of community education, are presented. The findings of an inquiry conducted to probe the community's views on what Eskom does to reach out to them in terms of electricity usage were examined in the context of community education. Some implications of these findings point out that partnership, trust, continuous dialogue and closeness between the community and Eskom are significant. Implications highlight, among other things, the importance of a grounded theory on which the future programme should be based.

- Description: Abstract: Eskom Holdings SOC Ltd (a State-Owned Company), Registration Number 2002/015527/30, is South Africa’s primary electricity supplier which is wholly owned by the South African government. Eskom’s mission is to provide sustainable electricity solutions to grow the economy and improve the quality of life of the people in South Africa and in the region. Owing to its strategic importance in the country, Eskom is compelled to procure different commodities and services strategically to ensure sustainable electricity provision to consumers while driving supplier development for security of supply. As a result, strategic sourcing was introduced as a way to procure commodities and supplier development as a mechanism to drive industry growth in the energy sector. To maximise multiple benefits for the company, integration and collaborative framework between strategic sourcing and supplier development is a fundamental aspect that should be given attention. The study analysed how strategic sourcing can be a catalyst for supplier development in Eskom. An exploratory research design and a mixed research methods (quantitative and qualitative) were employed. Non-probability purposive sampling was applied to select respondents and participants. Survey instruments (semi-structured questionnaires) were administered to commodity managers and middle managers in Commodity Sourcing and Supplier Development and Localisation departments respectively. Face-to-face interviews were conducted with executive management at Eskom. Data were analysed through content analysis. The results and findings of the study revealed that there is no unified and systematic approach on the planning, implementation and monitoring tasks between the two departments. It was found that procurement spend in Commodity Sourcing is used to drive supplier development objectives but commodity managers are not contracted on the objectives. Nevertheless, strategic sourcing is viewed as a great mechanism to advance supplier development objectives provided a joint planning, execution and monitoring and reporting is done appropriately. It is important that an operating model between the two departments or entire Group Commercial be reviewed and four recommendations and areas for future research are articulated. , M.Com.

An analysis of supplier relationship management practices in Eskom

- Description: M.Comm. , The primary objective of this dissertation is to perform an analysis of supplier relationship management practices in Eskom. Currently, Eskom is facing pertinent challenges such as a diminished reserve margin, increased unplanned generation plant outages as well as coal supply and quality constraints coupled with ever-rising primary energy costs. Since 1994, the demand for electricity has grown significantly on the back of robust economic growth. As a result, Eskom’s power system has an inadequate reserve margin which is at an all time low of around 8% and this does not compare well with the international standard of 15%. It is therefore evident that, as a national asset Eskom cannot overcome the current challenges successfully without strong partnerships with key suppliers. Impact of global expansion in the power sector has seen increased demand for utility specific commodities, and the resultant implication is the increased pressure on utilities to secure supply. Significant energy pressures are impacting on traditional procurement systems; as supply tightens it is vital for Eskom to intensify their efforts to build and sustain long-term collaborative relationships with key suppliers. With a more strategic view of procurement, companies are increasingly finding that different types of supplier relationships should be managed differently to achieve maximum value. Supplier relationship management has become increasingly sophisticated; buyer and supplier preferences are driven by circumstances in any relationship. The relationship portfolio analysis as explained by Cox, Sanderson and Watson (2000) demonstrates that buyer and supplier relationships centre on power, interdependence, and independence and they agree that relationships can be of an arms’ length, adversarial and collaborative nature depending on the power and style of management. Electricity is an important sector in the South African (SA) economy, despite its relatively small share of the Gross Domestic Product (GDP). Eskom has a capital expenditure budget of R800-billion for the next 20 years (Venter, 2007). An overview of the electricity industry in SA covering key highlights on the evolution of thinking on energy developments in the country and the resultant implication for supplier relationship management is discussed. Eskom supplies about 95 percent of South i Africa's electricity, and the recent power crisis had far-reaching implications for the economy. Some economists say that Eskom’s power crisis could slice two percentage points off SA’s growth rate, sending it below 3% for the first time in a decade.

- Description: M.Ing. , Water gives life. It waters the fields of farmers; it nurtures the crops and stock of rural communities; it provides recreation for our children, our friends, our families; it supports our power generation, our mines, our industry, and the plants and animals that make up ecosystems. Water is the key to development and a good quality of life in South Africa. South Africa's water belongs to its people. It is the task of the South African Government to care for this water, to seek its fair distribution, and to facilitate its wise use for, amongst other things, social and economical development. Issues such as water resource management, use, protection, water services, etc., are presently governed by a number of policies, acts and regulations. All South Africans has a responsibility regarding the management of the country's resources. The supply of water to its entire people makes it extremely important to optimise the use of this scarce source. Access to water and water availability remains a key factor in ensuring the sustainability of development in Southern Africa. The coal fired power industry is a major user of natural resources; coal for fuel and water for steam generation as well as the cooling systems. It is estimated that 1.5% of the water abstracted in South Africa is used for power generation. The power industry receives its water mainly as abstraction from surface impoundments in the form of rivers and dams. Eskom, as a strategic user of water, is mindful of the importance of water to its business, as well as the development of the country. In addition to the interests of the government as the shareholder, Eskom recognises the legitimate interests, as stakeholders, of specific government departments, employees, consumers, suppliers, investors and lenders of capital, rating agencies, the media, policy and regulatory bodies, trade unions, non-governmental groups and local communities in its affairs. Eskom needs to ensure, through an effective water management strategy, that water is used wisely and effectively and that Eskom's impact on local water resources (surface and underground) is minimised. Eskom therefore has to manage water resources in a manner that will sustain the ecological integrity, support social development and ensure economic growth. Eskom has undertaken to benchmark the power generation industry, in co-operation with the DW AF, in a project aimed at developing the principles of water conservation and water demand management. In order to effectively manage water quality and quantity at Eskom's power stations, and to show Eskom's commitment with regard to water conservation and use, Eskom has compiled its own water and environmental policies.

- Description: M.Sc. , Electrical energy has evolved to become the main source of energy as it fuels the processes in industry and other sectors. Electricity, generated at a power station, has to be transmitted to the users through transmission powerlines. Strips of land, in the form of servitudes, need to be acquired for the erection of these powerlines. Because this land passes through agricultural areas, residential areas and industrial areas which do not belong to the power utilities, these utilities need to acquire this land. The inability to acquire these strips of land is proving to be a problem for Eskom; in fact, it has been dubbed one of Eskom’s greatest risks (Seabe, 2010, Personal Comment). Hypotheses in respect of the problems pertaining to the acquisition of servitudes for transmission powerlines have been formulated with the supposition being that, by nature, these problems are not only biophysical, but also socio-cultural. Those classified as sociocultural problems are dependent on human behaviour: it is people who grant servitudes, and also people who own the land on which the servitudes are required. These problems, if not identified and addressed, have the potential to manifest at a later stage, causing conflict between the proponent and the landowner and in turn resulting in the electricity supply in South Africa being sporadically curtailed. It is therefore imperative that the problems pertaining to the acquisition of servitudes be investigated and analysed, and that methods be devised from the lessons learnt through investigating these problems. These methods, if implemented correctly, should minimise conflict between the landowners and Eskom and subsequently avert the risk of Eskom being unsuccessful in acquiring servitudes. These methods should also facilitate an improved, effective and successful servitude acquisition process, which will in turn ensure a continuous supply of electricity.

By combining services that are performed by different units within an organisation into a single business unit that allows each business unit to access those services, companies have been able to attain some of the benefits mentioned above. Process design is one of the critical activities that have to be performed to implement a shared services unit. Some companies, however, have not been able to optimally design processes in a way that adds value to the performance of a shared services unit. This study is a case study that explored how business process design could be utilised as an enabler to improve the performance of the Eskom Finance and Procurement Unit at Eskom Megawatt Park, in Johannesburg. Through an explorative study of the shared services process design project, the researcher studied how the processes were designed and implemented for the Eskom Finance and Procurement Shared Services. The study was able to identify important process design structures and principles, tools, and techniques that can be utilised to optimally design processes for a shared services unit. It also evaluated process design activities and processes to identify the gaps in process design as well to understand the impact of process design on Eskom.

- Description: M.B.A. , Eskom, South Africa's electricity utility, is the electricity supplier for South Africa. It has 20 power stations with a nominal capacity of 39 154 megawatts. Eskom is among the top five electricity utilities in the world in terms of size and sales and strives to remain one of the lowest-cost producers of electricity in the world. Eskom supplies 98% of the country's electricity requirements, which amounts to more than half of the electricity generated on the African continent.

- Description: M.B.A. , Eskom, South Africa's electricity utility, is the electricity supplier for South Africa. It has 20 power stations with a nominal capacity of 39 154 megawatts. Eskom is among the top five electricity utilities in the world in terms of size and sales and strives to remain one of the lowest-cost producers of electricity in the world. Eskom supplies 98% of the country's electricity requirements, which amounts to more than half of the electricity generated on the African continent. Eskom supports the development of a Southern African transmission grod to encourage cooperation and accelerate economic growth in the region. Eskom support employment equity and encourages employees to develop to their full potential through training.

- Description: Abstract: Over the last decade, South Africa has been experiencing an electricity supply crisis. This power crisis has been threatening the stability of the national power grid. The crisis was caused by insufficient generation capacity as well as an increased demand for electricity. In order to counteract this situation, the state owned electricity utility, Eskom decided to increase its power capacity by building new power plants, and implementing demand side management (DSM) initiatives to save energy. All of this came at a cost. Therefore, the present study was aimed at helping decision makers in the South African electricity sector to decide on the optimum funding allocation for the above projects. The research methodology adopted in this study was cost analysis. Three levels of cost comparison were developed in this study. These were based on power generating technologies (coal, gas, nuclear, wind, concentrated solar power, and solar photovoltaic), and on DSM programmes (residential mass rollouts, standard offer programme, standard product programme, performance contracting programme, and energy services companies model mass rollouts). The first level analysed the costs of building power plants as well as costs of producing electricity using different power generating technologies. The second level analysed the costs of implementing DSM programmes as well as costs of saving energy by implementing DSM programmes. Lastly, the third level analysed the costs of building power plants against the costs of implementing DSM programmes, as well as assessing the costs of producing electricity versus the costs of saving energy. The results for both power plants and DSM measures were tested through sensitivity analyses. At the first comparison, it was revealed that renewable energy technologies have the highest costs, higher than other generating technologies. At this level, a conclusion was drawn up in three parts noting that (1) although renewable technologies are expensive, they should be given more weight due to the fact that they are inexhaustible, (2) they guarantee safety to the environment, and (3) they do not emit greenhouse gases into the environment. At the second level of cost comparison, it was demonstrated that residential mass rollout (RMR) has the highest cost, higher than any other programme. At this level, it was concluded that due to the target market of RMR, which is residential sector, RMR should be given more weight, because more energy is wasted in this sector. It was further observed that residential consumers use a lot of electricity during peak period, and this increases during the winter season. The third level of cost comparison demonstrated that DSM measures were the resource alternative available at the lowest cost to the electricity utility. Hence, DSM initiatives could help to alleviate power outages issues and therefore, delay the need for building new power plants. Since DSM initiatives were found to be cheaper to run, their implementations meant that the utility would save billions of Rand by not using large amounts of water, coal, fuel, operating the plant at lower levels of intensify and doing less maintenance on the power plant. , M.Ing.

- Description: M.Ing. (Engineering Management) , Abstract: The energy sector in South Africa has experienced major shortfalls in meeting the country’s energy demands. This lack of generating capacity is attributed to delays in the approval of new infrastructure and the increase in the country’s economic growth between the years 1994 and 2007 [1]. The electricity producer Eskom Holdings SOC (State Owned Company) Limited, has since implemented initiatives that are aimed to address the energy supply shortfalls. One such initiative is the refurbishment of the existing operational fleet of coal fired power stations. The overall intention of this initiative being to extend plant operating life, improve reliability and availability as well as to align these assets to current safety standards. The operating life of power stations often resides between forty to fifty years. Within this lifecycle instrumentation & control (I&C) upgrades are planned and executed to secure the continued reliable operation of the generating assets. These projects often entail the full upgrade or refurbishment of the power station’s process control system [2]. The research identifies the critical success factors to be considered for I&C projects rolled out within the energy generating sector in South Africa. The study is established on a comprehensive literature review that provides insight into the South African energy industry, I&C environment and business architectural framework processes. The review covers the spectrum of people, plant and processes and sheds light onto the critical success factors (CSFs) to be considered during the different project phases. The identified CSFs are used to formulate the framework of a survey distributed amongst key stakeholders from the operating, engineering, maintenance and project management fraternity. The results of the survey is analysed to identify the relevant CSFs across the different project phases. An insight into the organisation’s change management maturity is provided by evaluating the identified CSFs with those established through the literature review. The research work concludes with the proposal of CSFs for I&C projects within the power generation industry and provides recommendations for future studies.

- Description: M.Sc. , The need for a fire-induced flashover (power line arcing to the ground) probability index for Eskom transmission (high voltage power) lines became evident soon after the installation the Advanced Fire Information System (AFIS) in 2004. AFIS is a satellite based fire detection system that utilizes polar and geostationary satellite sensors to detect fires as small as 50 m x 50 m in size. As soon as a fire is detected by either, the Terra, and Aqua Moderate Resolution Imaging Spectro-radiometer (MODIS) or Meteosat Second Generation (MSG) geostationary satellites close to any of the 28 000 km of Eskom transmission lines, a cell phone and email text warning is sent out to line managers responsible for the management of the particular section of line affected. Between 3000 - 6000 fires are recorded annually close to Eskom transmission lines with a fire-induced flashover rate of 100 - 150 transmission line trips per year. Fire-induced flashovers occur when the air around high voltage transmission lines are ionised due to a hot flame (> 500° C). As the air becomes conductive, electricity can move from the line to the ground in the form of a lightning flash. Studies have shown that one flashover can cause an average of three voltage depressions (dips) on the electrical transmission system, and each voltage depression can cause damage to a customer’s production ranging between R5000 and R150000 per dip. The aim of this study was to develop a prediction model with the ability to accurately predict fire-induced flashover occurrences on Eskom transmission lines in order to reduce the large amount of false alarms (SMS and email messages) produced annually by AFIS. The prediction model in the form of a probability index was derived from a combination of remote sensing satellite products as well as weather forecast variables. With the MODIS active fire product as base layer, weather forecast variables in the form of air temperature, relative humidity, wind speed and wind direction, as well as topographical elevation and a satellite derived vegetation condition product served as input to the predictor data set of the model, while flashover statistics for 2007 provided the target data set within a Classification and Regression Tree (CART) analysis. iii The prediction capabilities for each of the variables were evaluated based on their prediction accuracy and Receiver Operation Characteristic (ROC) value in terms of the validation data set. Wind speed, relative humidity, wind direction and air temperature were shown to have the highest predictor importance and were used to develop the probability index calculated from a logistic regression analysis. The Fire-induced Flashover Probability Index (FIFPI) was tested through simulations of predictor variables and was also compared to existing Fire Danger Indices (Willis et al. 2001). The FIFPI was able to outperform most of the standard Fire Danger Indices (FDI’s) with only the McArthur Grassland Index (MK 4) which demonstrated some prediction capability. The importance of wind direction as an environmental component in the prediction of flashovers became clear as it tended to decrease the misclassification rate from 4.45% when only wind speed, relative humidity and temperature were used to 3.87% when wind direction was added. The research has shown that wind speed, wind direction, relative humidity and temperature can be used as an indicator of possible fire-induced flashovers underneath Eskom transmission lines. However, additional research is needed to verify the results from 2007. Ideally at least 3 years of data should be used.

- Description: M.Ing. , The aim of this research is to develop a Project Management Maturity Measurement Model to evaluate project management efficiency in a large Parastatal such as Eskom Distribution. This model will identify areas of improvement to assist a large Parastatal in improving their project management performance. It will eventually assist the organisation to build a culture of project management excellence. The hypotheses for the study were that firstly, the Parastatal does implement project management practice processes as advocated by project management bodies of knowledge. Secondly, a Project Management Maturity Measurement Model can be successfully implemented at a large Parastatal and help the Parastatal to identify project management grey areas that require improvement. Thirdly, a Project Management Maturity Measurement Model could assist a large Parastatal with project management improvement as a result of areas of recommendations. The method used to collect the required data for analysis and interpretation was the descriptive survey method. A customised survey questionnaire was developed to obtain data from research sample. Data was analysed using appropriate statistical techniques. The research sample was defined as the people who are primarily responsible for project, programme and portfolio management at a large Parastatal. The results of the data analysed pin pointed project management process weaknesses and possible improvement opportunities. Three main areas of improvement have been identified, namely applying lessons learned from previous project into future project, performing benchmarking to improve performance and project control processes. The findings of this study support the abovementioned hypotheses, and the insights provided and recommendations made will be of great help to a large Parastatal on its road to continuous improvement and building a culture of project management excellence.

- Description: M.Com. (Econometrics) , An attempt has been made in this study to model electricity sales of Eskom with the aid of an econometric model. The study examines the history of econometric modeling and the applications thereof. These applications include forecasting, policy simulation and policy analysis. The sales of electricity within the specific sales categories is estimated and simulated with the use of an econometric model. The model is specified according to the expected dependent and explanatory variables. The a priori theoretical considerations concerning the size and sign of the parameters of the function are also included in the specification, as well as the mathematical form of the model. The specification process of the econometric model is based on econometric theory and on available information relating to the phenomenon being studied. The method of ordinary least squares is used in the estimation of the parameters of the model. As this is an econometric study, the emphasis is on the evaluation of the results. Economic a priori criteria, statistical criteria and econometric criteria are used to evaluate the results of the parameters obtained by the method of ordinary least squares. Several tests, including the Goldfeld Quandt test for heteroscedasticity, the Durbin-Watson test for auto correlation and the Frisch analysis of multicollinearity are executed. The overall results of the tests to which the model was subjected, was satisfactory. The best functions are combined in a structured model. This model is simulated with the use of the Gauss-Seidel-method and forecasts of historical values are obtained. Statistical tests for the validation of these results, as well as Theil's inequality coefficient are applied to test the forecasting power of the model. The results of the ex post forecast for the period 1988.1 to 1995.1 emphasize the usefulness of the model as a forecasting device and the dynamic simulation demonstrates the ability of the model to reproduce the historical data from which it is estimated.

- Description: M.Com. (Business Management) , In February 1990 the State President of the Republic of South Africa unbanned the political organisations that were previously banned. This set the scene for full and free elections. It also brought new role players to the fore. Parastatal institutions, including Eskom, now faced the problem of having to adapt to the new environment. or face the possibility of serious intervention from a new Government. During 1990 Nedcor and Old Mutual formed a team of experts, including one specialist from Eskom, to seek alternative paths that South Africa may embark on in an attempt to foster an environment that would enhance the possibility of a successful transition to a democratic South Africa. The team produced a scenario, which became known as the "change of gears" scenario. One of the cornerstones of this scenario is a kick-start of the economy, inter alia through supplying with electricity those citizens who do not yet have access to electricity. With a view to this the Nedcor/Old Mutual scenario suggests an electrification rate of one million houses per annum. This figure was criticised because of the negative effect it would have on the balance ofpayments. The Nedcor/Old Mutual scenario was presented to many parties, including the Cabinet and the ANC Executive. Although criticism was expressed against this scenario, it served a meaningful purpose in that it was probably one of the impetuses for the ANC's national meeting on electrification and the creation of other scenarios, such as that of Van der Berg. as well as other studies such as this dissertation. This dissertation, comprises an environmental scan of the needs and wants of the parties affected by electricity and electrification. These parties were identified as: Eskom; the local authorities; the people who currently do not have access to electricity; the central government; the unbanned political parties; and the consumers ofelectricity. It has been ascertained that South Africa, in the form of Eskom, has an excess power generating capacity of approximately 25 percent; that 65 percent of the population does not have access to electricity; and that the price of electricity is low as compared to that ofthe rest ofthe world. It has also been established that in South Africa the percentage ofhouseholds (ii) electrified is approximately twice as high as that of any other country on the sub-continent. From this it was concluded that the issue of electrification is a political one, nevertheless an opportunity to improve the economy. The views of the interest groups were studied, with particular emphasis on the views expressed at the ANC's first national meeting on electrification.

- Description: M.Com. (Business Management) , In February 1990 the State President of the Republic of South Africa unbanned the political organisations that were previously banned. This set the scene for full and free elections. It also brought new role players to the fore. Parastatal institutions, including Eskom, now faced the problem of having to adapt to the new environment. or face the possibility of serious intervention from a new Government. During 1990 Nedcor and Old Mutual formed a team of experts, including one specialist from Eskom, to seek alternative paths that South Africa may embark on in an attempt to foster an environment that would enhance the possibility of a successful transition to a democratic South Africa. The team produced a scenario, which became known as the "change of gears" scenario. One of the cornerstones of this scenario is a kick-start of the economy, inter alia through supplying with electricity those citizens who do not yet have access to electricity. With a view to this the Nedcor/Old Mutual scenario suggests an electrification rate of one million houses per annum. This figure was criticised because of the negative effect it would have on the balance ofpayments. The Nedcor/Old Mutual scenario was presented to many parties, including the Cabinet and the ANC Executive. Although criticism was expressed against this scenario, it served a meaningful purpose in that it was probably one of the impetuses for the ANC's national meeting on electrification and the creation of other scenarios, such as that of Van der Berg. as well as other studies such as this dissertation. This dissertation, comprises an environmental scan of the needs and wants of the parties affected by electricity and electrification. These parties were identified as: Eskom; the local authorities; the people who currently do not have access to electricity; the central government; the unbanned political parties; and the consumers ofelectricity. It has been ascertained that South Africa, in the form of Eskom, has an excess power generating capacity of approximately 25 percent; that 65 percent of the population does not have access to electricity; and that the price of electricity is low as compared to that ofthe rest ofthe world. It has also been established that in South Africa the percentage ofhouseholds (ii) electrified is approximately twice as high as that of any other country on the sub-continent. From this it was concluded that the issue of electrification is a political one, nevertheless an opportunity to improve the economy. The views of the interest groups were studied, with particular emphasis on the views expressed at the ANC's first national meeting on electrification. The views of the parties were reduced to a list of sixteen requirements/expectations. These were divided into two groups, these on which there are a high degree of consensus and those on which agreement would have to be obtained. The latter included the pricing issue for prepaid meter customers versus the other small power users; the effect of poor load distribution on the price paid by black local authorities; the gross underutilisation ofmanpower in the industry, due to the fragmented structures; the redistribution of wealth; strong Government intervention; and the question of the level ofprofits in the industry. From this follows the recommendation that the electricity supply industry be onsolidated under the Eskom structure and that the issue around electrification be depoliticised.It is also recommended that a stable rate of electrification of approximately 250 000 houses per annum be maintained.

- Description: M.Com. (Local Economic Development) , Abstract: In 2008 South Africa experienced a period of constrained electricity supply, which led to wide-spread blackouts. In order to deal with these electricity capacity constraints, there has since been a shift in focus in the country with significant investment in this sector. Most studies in the energy-economic growth nexus have focused on the economic effects of energy use. There is a body of literature that has looked at infrastructure investment and economic growth, but does not treat energy investment as a particular kind. We argue that it is not only energy consumption that matters for economic growth, but the investment it its production as well. Investors might carefully watch energy capacity development in order to make their investment decisions in other economic sectors, which make investment in energy a possible trigger of capital formation in other sectors and subsequent economic growth. With this hypothesis, our paper investigates the causal relationship between investments in energy and capital formation in other sectors of the economy on one hand, and the causal relations to economic growth on the other. We use annual data for 228 South African municipalities from 1993 to 2015. The paper uses the newly developed heterogeneous panel Granger causality methodology, which improves the traditional causality approaches in accounting for heterogeneity and cross-sectional dependence in the panel data. Traditional approaches were developed under the assumption of homogeneity in slope, intercept or both, and the independence of panel units. Our findings are therefore more robust to heterogeneity issues and account for individual differences between municipalities. Another difference between this paper and the majority of academic work is our shift in focus from a national level to a local/municipal level. Our findings suggest that there is an overall bidirectional causal relationship between investments in energy, capital formation in other sectors of the economy, and economic growth. This finding highlights the potential that investments in energy have to trigger capital formation in other sectors and promote economic growth. Such findings will have significant local economic development implications in terms of the role of energy capital in attracting capital in other sectors, with broader implications for economic growth in view of job creation and poverty reduction.

- Description: Abstract: Construction projects are well known to fail or delays beyond their intended contractual duration due to multiple of reasons that pertains to project management. The commonly used construction term for such project management deferrals is referred to as delays. Delays of construction project in developing countries are disadvantageous for the economy’s progression. Therefore the research aims to determine the causes of delays in the South African construction industry, predominantly focused around Eskom capital expansion projects. It also seeks to identify potential project management activities to manage the causes of delays. The motive for conducting this research is to improve and develop the project managers’ knowledge and skills regarding project delays and how to management them. And also contribute in developing the project management society about the delays identified both locally and in the internationals constructions industries. Quantitative methodology outlining the research investigations was used to carry out the study. Snowballing sampling technique was applied to collect primary data, with the use of structured hand-outs, questionnaires and emails. Data was collected in three of Eskom construction sites. In addressing question one of the research, an initial 38 common delays were researched from various literatures on the same topic. From the 38 delays found in literature, the top 20 common causes were derived. Thereafter the highest top 5 and the least rated 5 of the 20 common causes of delays were selected for discussion. Subsequently the potential project management activities to manage the identified the causes of delays were researched and tabled. The top 5 rated causes of delays were matched with the ideal project management activities and further elaborated with supporting literature and survey results... , M.Phil. (Engineering Management)

- Description: Abstract: The National Energy Regulator of South Africa (NERSA) has implemented an Incentive- Based Regulation (IBR) scheme that either rewards or penalizes distributors on the System- Average Interruption-Duration Index (SAIDI) and other network performance indices [1]. The optimal placement of automatic reclosers (auto-reclosers) is seen as a cost-effective measure to reduce the system-average interruption-duration index (SAIDI) impact along a medium voltage (MV) feeder. An auto-recloser is seen as a function of distribution automation (DA), thus reducing customer impact. A great advantage of a correctly implemented and operated DA system can improve network reliability significantly. This dissertation evaluates the empirical relationship between recloser placement and reliability from the perspective of control and instrumentation within ESKOM. It also puts forward an additional performance-improvement framework that can be implemented to achieve RAM (Reliability, Availability and Maintainability) management. Loop automation functionality is also under discussion; this is a Distribution-System Automation-scheme that restores the supply to the fault-free sections of a network, if they have been disconnected, because of a fault in another section of the network. Loop automation can also restore the normal network configuration automatically, when the faulty section is repaired. The process of isolating the faulty section and re-configuring the network to restore supply back to the fault-free sections is the first capability of Loop Automation. This research investigation assesses two different scenarios, namely: A conventional implementation of auto-reclosers on MV networks using Eskom reliability standard; and (ii.) the findings of a case-study using this recloser implementation (loop automation) to improve the reliability and the system’s performance. Results obtained are presented and discussed. , M.Phil. (Engineering Management)
