Thesis (DTech (Public Management))--Cape Peninsula University of Technology, 2008 / The research explores an evaluation of cross-border electricity trading among countries of the Southern African Development Community (SADC). Understanding this trading achieve through an analysis of various global electricity markets. The research disclose that in the electricity markets in Europe, North America, South America and Asia analysed in this thesis, none managed to successful eliminate power shortages. Their situation, however, is different from that of the Southern Africa Power Pool (SAPP). The apparent poor design of the SAPP as a regional power pool impacts negatively on power trading within its region. A strategic public management model was used to analyse the organisational dynamics of the electricity companies of the three countries selected for this research (Democratic Republic of Congo, South Africa and Zimbabwe). A Strength Weakness Opportunities and Threats (SWOT) analysis carried out on these markets indicated that there are problems among different electricity companies, each requiring a solution. Each country's evaluation highlighted a need for an accountable government to implement a goal-directed policy to militate against any dysfunctional operations by the electricity companies. The quantitative and qualitative data analyses of the fieldwork results showed the SAPP had struggled hard to increase the capacity of members' power trading. The study indicated internal problems in terms of increasing trading volumes. The time series analysis showed power trading in the short-term electricity market had decreased annually. Linear regression analysis also indicated a decline in the capacity of the SAPP. A number of factors could explain the reduction of capacity in the SAPP, but the research results suggested a strong probability that electricity capacity would decrease further, as the countries, trading in the power pool have experienced decreased electricity volume annually because of internal demand. In addition to a number of. recommendations, the research proposes a normative model that could be used by nations to manage and assess the electricity market. An understanding of the input as adapted from Easton inpuUoutput normative 11 transformational systems model, in terms of different governments, should assist policy-makers to transform the power trading generating distribution industry. Global experience shows the need to establish a normative transformation of the electricity industry in the SADC region. It is clear from the results of this study that the SADC electricity markets have been poorly transformed in terms of a particular normative guideline. The situation has also disadvantaged the SAPP, which, in recent times, had less electricity capacity with which to trade. Implementation of the normative model in the context of this study sought to analyse all aspects that might influence the transformation of the electricity sector, and to grow a currently dysfunctional state to that of functionality and reliability. While each country faced its own reality in terms of the transformation of its public enterprises, the study recommends the normative model be implemented in the same way in each selected country.

The electricity market in the South African economy uses specialised instruments in forecast-ing the energy load to be delivered. The current status quo operates with several forecasters from different offices, departments or businesses predicting for different purposes. This be-comes a challenge to derive a consolidated forecast. This study has attempted to develop a consolidating instrument that will merge all the forecasts from different offices, departments or businesses into one so-called ‘official forecast’. Such an instrument should be able to predict with accuracy the anticipated usage or demand. Article [18] examined patterns across G7 countries and forecasters to establish whether the present bias reflects the inefficient use of information, or whether it reflects a rational re- sponse to financial, reputation and other incentives operating for forecasters. This bias is particularly true for any electricity utility as forecasting is undertaken by different divisions; therefore each division has its own incentives. For instance, the generation division will tend to overstate their forecasts so as that there is no possibility of a shortage, whereas distri- bution (sales) might understate so as to give the impression of being profitable when more units are sold to consumers. Thus, the study attempts to rectify this bias by employing statistical tools in consolidating these forecasts. The results presented in this paper propose a newly developed procedure of consolidating energy demand forecasts from different users and accounting for different time horizons. Predicting for the short-term and long-term involves different measuring tools, which is one aspect of prediction this paper tackles.

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.

M.Phil. / The problem that exists in the developing areas of the Northern Cape area of Eskom (and also in all other developing areas in South Africa), is to make the correct decisions in terms of electrification, marketing and sales of electricity and electrical appliances when electrifying these areas. This study investigates this problem. The results from field work before and after electrification and recommendations form the main part of the study. The main methods followed for this study were as follows: Previous pre-electrification studies over a period of roughly six years in 82 developing areas were aggregated into 33 tables with maximums, minimums and averages calculated, including compiling 52 graphs. This process took the best part of one year. This gives an in-depth combined view of energy - and socioeconomic aspects particular to the Northern Cape. A needs analysis was also done amongst role players inside and outside Eskom, inter alia the management of Eskom, municipalities, Rand Afrikaans University, electrical contractors and district councils. The most important needs were investigated during field work done for this study in 1994. Data processing in dBase and Microsoft Excel and statistical analysis in Statgraphics was done, and the findings were taken up in four internal before/after publications during 1995 and 1996 and finally, in this study. It provides a clearer insight into electrification -, socio economic and health aspects in the developing areas of Northern Cape before and after electrification. Electrification in developing areas in Angola, Zambia and Zimbabwe is uneconomical and in many cases has just about come to a standstill. Electrification in Namibia and Botswana is progressing slowly, at a cautious economic pace. Amongst the most important findings (in another 29 tables and another 58 graphs) for the Northern Cape area of Eskom are: The number of prepaid customers in the developing areas grew from less than 100 in 1989 to more than 38 000 in 1996, an increase of more than 20 000%. At this stage these customers of Eskom consume 4.148 GWh of electricity p.m., the equivalent of about 4 148 big households, each consuming 1 000 kWh (units) of electricity. This translates to only 109.16 kWh (Eskom ±70 kWh nationally)per customer p.m., which is not even nearly economical to Eskom. It must be remembered that it took 20 years in Ireland for electrification programmes to become economically viable. The target of Eskom in South Africa vary from 350 kWh to 572 kWh p.m., the latter which can only be achieved by "second phase" electricity consumption, i.e. by using heavy appliances such as geysers as well. When the developing areas have been fully electrified, total electricity demand in South Africa could increase by 7.4%, which could cause the building of another 1.26 big power stations. After electrification, there was a statistically significant reduction in the monthly average spending on wood and coal in the developing areas of Northern Cape. The electrical appliances mostly in use (after electrification) are irons, kettles and TV's. After electrification there was a statistically significant increase in the percentage of the maximum average "marketing potential" of appliances. The electrical appliances that most residents still want to buy after electrification, are washing machines, fridges and geysers. After electrification, only 68.63% of kettles are electrical types (on average). Nearly all electrical appliances are used during the peak hours of Eskom. The maximum amount that residents are prepared to spend on electricity, is R75.89 p.m., compared to R53.64 p.m. before electrification. The recalculated total average spending on energy (excluding petrol and diesel) is R91.72 per month before electrification and R121.21 p.m. after electrification. The average level of education is between standard 5 and 6 compared to between standard 3 and 4 before electrification (this is also statistically significant). The average income of households is R943.89 p.m.,compared to R507.59 p.m. before electrification. The average number of people per household is the following (pre-electrification figures in brackets): men 1.05 (0.96), women 1.21 (1.17) and children 3.26 (2.98). The total number of people per household is 5.51 (5.11). Most residents are very satisfied with health services in their areas. The biggest group (on average 95.30%) in the electrified developing areas of Northern Cape make use of modern medicine. The next biggest group (on average 4.7%) make use of modern medicine and traditional healers.
