>Magister Scientiae - MSc / Over the past 5 years, South Africa has been experiencing a severe drought. This has caused industrial and agricultural processes, to compete for a limited supply of water. Since the economy relies mostly on agricultural activities, water consumption by industrial processes is taking its toll. One of these processes is the introduction of wet flue gas desulphurization (FGD) treatment at Eskom coal fired power stations. This dissertation explores the possibility of using membrane technology as a means of water recovery after the coal combustion flue gas has been treated with wet FGD. A lab-scale permeance testing system was specially built and modified to have complete thermal control of the environment inside the system. The permeance testing system produced a gas, similar to that of a wet FGD treated flue gas, which was then tested. A tubular lab-scale membrane module was designed and produced for the permeance testing system. The permeance figures of both Nitrogen gas and water vapour were determined for the membrane used in module production. These figures coincided with figures provided by the supplier, which warranted successful permeance testing. After success of the lab-scale testing, the data was used to design and develop a pilot-scale membrane module. This module was designed to meet pre-determined requirements as set forth by the project team. Producing lab-scale membrane modules helped identify and address possible problems in pilot-scale module design. This lead to the successful design and construction of a pilot-scale membrane module that could be used to recover the water that is needed to run the wet FGD process.

Thesis (M.Com. (Business Management)) -- University of Limpopo, 2020 / This research focuses on the evaluation of the project management maturity at Eskom. The problem is that Eskom struggled with delivery of projects as planned. The main objective of this research was to identify an applicable PMMM to assess the project management maturity level of Eskom’s core business units, namely Transmission, Distribution and Generation, by assessing its capability to undertake projects effectively in order to provide electricity to the Southern Africa communities. A quantitative research methodology was selected. A survey was conducted with a closed-ended questionnaire made up of three parts (Applicable project management maturity model, project management culture and project management organisation strategy maturity). The population consisted of senior project managers, project managers, and related project management personnel from Eskom in MegaWatt Park Johannesburg. 200 questionnaires were distributed to the Eskom business units, namely Distribution, Generation and Transmission project management employees, selected purely on their experience and knowledge, hence purposive sampling was used. Surveys were emailed to the respective project management personnel with the help of the senior manager. 133 were returned. This is a response rate of 66 %, which was deemed acceptable. Descriptive statistics was utilised to assess the project management maturity level of Eskom business units. Statistical Package for Social Sciences version 24 (SPSS) was utilised for the purpose of data and reliability analysis. Correlation and linear regression analysis were undertaken to evaluate influence of maturity levels of organisational strategy and culture on the project management maturity level. A Cronbach’s Alpha was utilised to measure the reliability of the data. It was concluded there were project management process areas, not performing well. Namely: project time management, project cost management and project procurement management. The assessment of project management organisational factors indicated that project management culture maturity did not perform well. It performed under the project management maturity level of Eskom. The recommendations of this study are that the applicable project management maturity model proposed should be continuously utilised to evaluate the project management maturity of Eskom on an ongoing basis; there should be a significant cultural change and a project management office should be established.

This study investigated the causes of employee dissatisfaction by means of a case study of the Business Application Solution Centre (BASC) at the Eskom Academy of Learning (EAL). The rationale for the study was to contribute further to a general understanding of employee dissatisfaction. This study highlighted the issue of the under-representation of blacks and females (of all races) in senior positions, and further emphasised appointment and recruitment issues that promote unfair labour practices, organisational culture and structure issues that undermine workplace relations, and the extent to which management responds to the abovementioned issues. A mixed method approach was employed to gather data from BASC employees. Qualitative data was collected by means of one focus group discussion and nine in-depth, face-to-face interviews. For the focus group and face-to-face interviews, purposive sampling was used for the selection of respondents, in order to ensure representation on all race, gender and occupational strata. A semi-structured questionnaire was used for both the focus group and face-to-face interviews. The questioning route was guided by the themes of gender, appointment and recruitment issues, culture and structure issues, and management response and practice. Quantitative data was collected by means of an online survey. Even though the online survey link was sent to employees on all strata, top managers did not participate. The use of a web-based online survey had an element of immediacy and also ensured maximum confidentiality, as responses were transferred to a development server with no link or trace to the respondents. The study revealed many underlying causes of employee dissatisfaction, such as the following: (1) the main drivers of black and female under-representation in top positions were lack of skills development, mentoring and career-pathing; (2) among the recruitment and appointment practices leading to employee dissatisfaction was the appointment of employees to ‘acting’ rather than permanent management positions; (3) there was a perception that managers abused their authority by promoting their favourites and overlooking those who they did not like; (4) although an affirmative action (AA) policy had been implemented at BASC, it was felt that employees should be appointed and promoted on merit, and that this should be accompanied by mentoring; (5) in some instances, the hiring of consultants deprived employees of opportunities to perform critical tasks. The fact that consultants were paid more than employees was also a source of discontent; (6) appointment criteria were non-transparent, and respondents revealed that they knew who was going to be appointed even before the recruitment process had been completed; (7) a bureaucratic culture was found to be the main organisational culture issue undermining workplace relations. On the other hand, a culture of teamwork appeared to reduce dissatisfaction and enhance unity; (8) the major organisational structure issues undermining workplace relations were managers who lacked managerial competencies and unequal payment on the same grade; (9) employees who stood their ground were given a low rating during performance appraisals. Others were bullied by senior managers and colleagues, who were rude towards them; (10) a hostile working relationship between managers and employees was caused by managers who lacked human resource skills; and (11) junior managers were undermined by employees who bypassed them and went straight to senior managers to discuss workplace issues. This study addresses both the general lack of information regarding the causes of employee dissatisfaction in South Africa, and of employee dissatisfaction in the information and communication technology (ICT) workplace environment. The findings of the study will also contribute towards a better understanding of the general causes of employee dissatisfaction. The results of this study suggest that more in-depth investigations of the causes of employee dissatisfaction are necessary to fully address this issue, and in order to ultimately prevent a further increase in the rate of employee turnover. Some implications for further research became apparent during the course of this study: similar studies on employee dissatisfaction should be conducted with top managers; studies on the experience of managers appointed to acting positions should be undertaken; and follow-up studies on employee dissatisfaction should be conducted as causes are addressed and relevant interventions are implemented. / Business management / D.Litt. et Phil.

State-owned enterprises (SOES) exist in South Africa to drive economic development and improve service delivery to the large population. In order for SOES to achieve their mandates, as set out by government through their shareholding department, financial assistance by the state is imperative. In the case of the monopolistic power utility, Eskom, the South African government (SAGO) has 100% ownership which is managed through the Department of Public Enterprises (DPE). This total ownership by the state means that government is responsible in ensuring that the utility is operational and supported financially. The current study was aimed at evaluating the financial assistance received by SOEs in South Africa by the state with specific focus on Eskom. Eskom was selected from the eight SOES managed by the DPE for the purpose of focusing the research. The focus of the study was on the financial assistance to SOES in South Africa by the state. In 2008, Eskom received funding from different sources through loan intervention of the South African government. The loan and guarantees made available to Eskom by government, enabled the SOE to achieve a positive credit rating. Data for this research was primarily collected through academic journals, books, Acts, White Papers, legislation and personal interviews at the National Treasury (NT). The recommendation that this research states relates to the need for a single policy document on state financial assistance to SOES in South Africa. / Public Administration / M. Admin.

The cost of energy and national power utility Eskom, is currently under heated debate after the cost of electricity has more than doubled over the past three years, with another five annual increases of 8% approved by the National Energy Regulator of South Africa. The state owned utility has a monopoly on electricity production in South Africa having sole ownership over the transmission and distribution of electricity. Eskom produces 95% of South Africa’s electricity, predominantly from coal fired power stations, which is one of the leading causes why the country is one of the highest carbon dioxide emitters in the world. The question of independent power production and the use of our abundant renewable resources for electricity generation have been at the forefront with critics arguing against the heavy increases absorbed by industry and consumers. Although the renewable energy space is a well discussed topic, it is not well scientifically documented from an economic standpoint. The primary objective is to determine if renewable energy is price competitive with Eskom, or non-renewable electricity generation, by not only looking at the current scenario but also the future price projection and point where renewable energy is on parity with the grid price. For this purpose the Levelised Cost of Energy calculation method was used. Four different measuring instruments were produced for each technology namely, biogas, biomass, solar and wind and a financial model developed to determine the levelised cost, taking into consideration more complex financial structures, tax incentives, revenues and costs associated with by-products. From the literature it is clear that wind and solar, on a large scale, are competitive with the levelised cost of Eskom’s new build coal power plants and particularly wind, is lower than the grid price in 2017. The empirical study focused on a smaller scale of 1 to 5 megawatt and concluded that the levelised cost of wind energy is lower than Medupi coal fired power plant, currently under construction. The study also determined that biogas and biomass, under certain conditions relating to feedstock costs, are able to compete with Medupi and offer real and sustainable benefits in long-term energy supply. / MBA, North-West University, Potchefstroom Campus, 2015

Electrical energy supply in South Africa, provided by ESKOM, has become more expensive with regular price increases in the past seven years. Increases on an annual basis have seen the Mega flex tariffs quadruple in the years from 2007 to 2014. ESKOM is the sole supplier of electricity to Safripol, a polymer producer of which the manufacturing facility is located in Sasolburg, South Africa. This study will provide contextual information on what impact the escalation in cost of this utility has on the financial returns of the business. Independent power generation within the boundaries of the manufacturing site has become essential in order to alleviate the impact of inflated electricity costs, by at least 10% of the current total demand from ESKOM. Primary research includes different types of alternative electricity generation techniques that will be able to deliver a practical solution to the business. The means of operation, required resources and cost to produce are set out to provide input into concrete models that are scaled to the potentials applicable to the production facility. Total alternative electricity generation added up to almost half of the current total site electricity demand from ESKOM. This finding was truly beyond the expectations of the case study and clearly set out how understated the potential to generate electricity is within the industrial sector. / MIng (Development and Management Engineering), North-West University, Potchefstroom Campus, 2015

Look at the challenge of gender equity and global trends and its impact on Eskom / Women form 52 percent of the adult population in South Africa, the majority of the population, but their status in the workplace is marginalized. The Commission of Employment Equity 2003 report revealed that women represent only 37% of the total workforce and 21% of all senior management positions and only 14% of top management positions. The study firstly investigates if gender barriers are creating obstacles for the advancement of women to senior management positions. The evidence of the research indicates that barriers do exist and the most prominent of these barriers included organizational culture, men not supporting women in the organization, division of labour, lack of after care facilities and women not supporting each other. Organizations need to admit that barriers do exist before any meaningful change can be made to the working environment of women. Secondly the study investigates the impact of gender equity targets as some organizations are attempting to increase the number of women in their business. Although gender targets results in an increase of women in the workplace it has negatively impacted the morale of men. Lastly the effectiveness of some of the strategies like mentorship, training and development, networking, flexible work policies are examined. These strategies will only be effective if the organizations are committed in ensuring a balanced workforce. Organizations needs to realize that diversity should be seen as a great opportunity to be encouraged and nurtured. / Graduate School of Business Leadership / MBL
