- ItemCritical review of the levelised cost of energy metric(Southern African Institute for Industrial Engineering, 2016) Sklar-Chik, M. D.; Brent, A. C.; De Kock, I. H.The purpose of this paper is to critically review the ‘levelised cost of energy’ metric used in electricity project development. This metric is widely used, because it is a simple metric to calculate the cost per unit of electricity for a given technology connected to the electricity network. However, it neglects certain key terms such as inflation, integration costs, and system costs. The implications of incorporating these additional costs would provide a more comprehensive metric for evaluating electricity generation projects, and for the system as a whole. It is therefore recommended to refine the metric for the South African context.
- ItemIntegration costs of renewable energy technologies in future energy generation scenarios(Southern African Institute for Industrial Engineering, 2018-08-31) Sklar-Chik, M. D.; Brent, A. C.; De Kock, I. H.ENGLISH ABSTRACT: The objective of the paper is to understand the integration costs of renewable energy technologies (RETs) in future energy generation scenarios for South Africa. The study used PLEXOS1 to conduct a bottom-up hourly simulation, incorporating the high renewable energy scenarios of the World Wildlife Fund (WWF) for 2030, in which RET penetrations are projected to be below 20 per cent. After verification and validation of the model by PLEXOS subject matter experts, the final model was run with two cases: a base case, and a constraint case. The results for these two cases for the year 2030 exhibited system costs of R0.39/kWh and R0.48/kWh respectively. A secondary output was the levelised cost of energy values for a number of energy generation technologies. A sensitivity analysis subsequently revealed that the largest contributor to a change in system costs is the demand forecast, followed by an increase in renewable energy outputs. Finally, recommendations are made to improve future energy modelling research by addressing the key assumptions of this research inquiry.
- ItemAn investigation into the value of a standardised global pharmacovigilance reporting system(Southern African Institute for Industrial Engineering, 2017-11-22) Schurer, M.; Bam, L.; De Kock, I. H.ENGLISH ABSTRACT: Pharmacovigilance (PV) is based on the medical assessment of adverse medical events or drug-related problems, collected within organised health programmes. The large number of different PV systems, the equally large number of stakeholders within such systems (pharmaceutical companies, government regulatory bodies, national and international clinical regulatory bodies, healthcare workers, etc.), and the significant number of dimensions along which the effectiveness and efficiency could be measured, adds to this complexity. Furthermore, the lack of a standardised reporting protocol across the various PV systems hinders efforts to manage PV coherently on a global scale. This paper proposes the value of a standardised global PV reporting system by evaluating the systemic effects of the lack of such a standardised system.
- ItemA systematic literature review of sustainable urban planning challenges associated with developing countries(Southern African Institute for Industrial Engineering, 2019) Jooste, A. F.; De Kock, I. H.; Musango, J. K.ENGLISH ABSTRACT: The purpose of this study is to uncover the most prominent challenges that urban planners face when tackling sustainable practices in developing countries. The time frame was set to after the 2012 Rio +20 global summit. Therefore, only articles that were produced from 1 January 2013 till 31 March 2019 were included, as they would have adhered to the contributions and protocols set forth at the largest UN Earth Summit conference. In this study, a review of the sustainable urban planning challenges was conducted. The challenges are then grouped into topics that align with the theme of the type of challenge. Finally, the challenges are analysed to identify the most well-known and disruptive challenges that restrict urban planners in developing countries.
