Restructuring of the electricity supply industry in South Africa.Laban, Ivan. January 2003 (has links)
The monopolistic South African electricity supply industry is undergoing a transformation that would change its ownership and market structure. The objective of this study was to determine whether the strategic choice to transform the industry is indeed appropriate. A qualitative, case based study of the existing and proposed South African electricity supply industry was performed. Various strategic tools and techniques, related to both strategic theory and electricity supply industry models, formed the basis of the evaluation. It was found that to overcome the critical weaknesses in the industry and to take advantage of the opportunities present in the dynamic and complex electricity supply industry the restructuring is appropriate. The restructuring would allow the South African Government to meet its objectives of having an efficient electricity supply industry and meet the huge suppressed demand for low cost electrification. South Africa intends adopting the wholesale competition model, however this study recommends that it should implement the single-buyer model. Should the restructuring be successfully implemented, customers in the South African electricity supply industry can expect high quality electricity at a competitive price. / Thesis (MBA)-University of Natal, 2003.

Strategic alignment : an approach to the harmonisation of business and information systems strategiesThurlby, Bob January 1998 (has links)
Information Systems are fundamental to both the day to day operations and competitiveness of most organisations. As the rate of change in organisations continues to increase this dependency has become more critical. However methods for determining the Information Systems that an organisation needs have not moved forward to reflect these increases in organisational turbulence and new capabilities offered by Information Technology. Strategic Alignment is proposed as a new method for Information Systems Planning which recognises the dynamic role of Information Systems as an agent of change and to enable organisations to model and determine how Information Systems can be exploited to improve and transform Business Strategies. Important innovations in the method are incorporation of feedback to ensure that analysis of the interaction of the Information Systems and Business objects within the model is bidirectional. Also that the development of an Information Systems Plan is a complex process which has to be modular. This enables it to incorporate existing results and information where applicable and to deliver its results incrementally. The Strategic Alignment Method has been developed from extensive research which used the Electricity Supply Industry as the source of information because it was facing immense change after its privatisation. As a result detailed case study material is presented as well as the Strategic Alignment Methodology. Maintenance of an Information Systems Plan is also addressed. Once an Information Systems Plan is produced, its implementation can take a number of years. During this time the changes in Business Strategy and Information Systems capability will change. Strategic Alignment proposes methods that will ensure the ongoing harmonisation of the Strategies during the implementation of the plan. The practical nature of the research is reflected in the Addendum which describes the work that has been done to incorporate Strategic Alignment into ICL's services methodology and to train ICL Consultants in its use.

Integrated and synchronised approach to DSM initiatives.Begemann, Morne. January 2009
Demand side management (DSM) interventions aim to influence the way electricity is used by
customers through specific actions and programmes. A desired load shape is achieved by
encouraging electricity users to consume more electricity at times when excess capacity is
available and less during times of constraints. In South Africa, load management is a fixed
response between 18:00 and 20:00 and includes load shifting and load curtailment out of the
Time of Use (TOU) tariff peak period. Demand Market Participation (DMP), on the other hand,
is a more flexible curtailment initiative and is scheduled day ahead only if constraints are expected. This study evaluates the effectiveness of load management and DMP initiatives and proposes an
optimised approach. Customer responses to the TOU tariff and the alignment of system and
tariff peaks were investigated by making use of TOU metering and system sent out data. The
research shows that not all customers respond to the TOU tariff signal. System peaks and TOU tariff peaks are aligned however a number of system peaks occur out of the tariff peak periods. The research further shows that load management and DMP initiatives shift and curtail load effectively. Load management initiatives with an energy efficient component are very effective
and highlight the importance of energy efficiency as a whole.
Historical system sent out data was analysed and the results show that a significant number of
load management initiatives can become more dynamic. It was further evident that curtailment
initiatives contribute more to the system than load shifting initiatives. Load management
initiatives are initiated by TOU tariff peaks and not system peaks. Load management initiatives
could therefore be optimised if system constraints are used as a reference and not TOU periods.
It was also evident that load shifting initiatives do not add much value during the low-demand
seasons. The results of this study could be utilised to improve DSM initiatives. This study also
serves to influence future DSM strategies which will embrace a sustainable DSM programme. / Thesis (M.Sc.Eng.)-University of KwaZulu-Natal, Durban, 2009.

An analysis of rightsourcing in the electricity supply industry / Nerisha PillayPillay, Nerisha January 2011 (has links)
The country is currently experiencing a tight electricity schedule. The demand
for greater capacity than the country can supply is a reality. Raising
unemployment and poverty levels are a situation we contend with daily.
The aim of the study is to create a generic framework for right–sourcing in the
electricity supply industry. The various phases of strategy creation were
analysed to achieve this target. The process of identifying core business
processes was discussed. Strategic alignment is important for the success of
the Information Technology strategy; this study discussed how this could be
accomplished.
The various Information Technology sourcing strategies were examined. The
probability of a process being outsourced, stemmed from the simplicity and
repetitiveness of a transaction or process, and costs involved.
An empirical study was done with both quantitative and qualitative analysis.
The study looked at Contract Management, Information Technology Strategy
and Benchmarking.
A comprehensive right–sourcing framework was developed to assist in making
the correct decisions. This framework could guide new entrants to the ESI in
helping them shape their strategy and formulate a distinct competitive
advantage. It could assist them in meeting the growing capacity demands
faster and making a significant positive contribution to the economy. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2012.

The UK electricity market : its evolution, wholesale prices and challenge of wind energyCui, Cathy Xin January 2010 (has links)
This thesis addresses the problems associated with security of the electricity supply in the UK. The British electricity supply industry has experienced a significant structural change. Competition has been brought into the electricity industry and a single wholesale electricity market of Great Britain has been established. The evolution of the British electricity market raises new challenges, such as improving the liquidity of wholesale markets and developing clean energy. The wholesale electricity prices are less transparent and trading arrangements are very complex in the British electricity market. In this thesis a fundamental model, called a stack model, has been developed in order to forecast wholesale electricity prices. The objective of the stack model is to identify the marginal cost of power output based on the fuel prices, carbon prices, and availability of power plants. The stack model provides a reasonable marginal cost curve for the industry which can be used as an indicator for the wholesale electricity price. In addition, the government's targets for climate change and renewable energy bring new opportunities for wind energy. Under the large wind energy penetration scenario the security of the energy supply will be essential. We have modelled the correlations between wind speed data for a set of wind farms. The correlation can be used to measure the portfolio risk of the wind farms. Electricity companies should build their portfolio of wind farms with low or negative correlations in order to hedge the risk from the intermittency of wind. We found that the VAR(1) model is superior to other statistic models for modelling correlations between wind speeds of a wind farm portfolio.

Repercusión de las energías renovables en la liberalización del sector eléctrico en España: análisis comparativo incluyendo Reino Unido, California y BrasilMartinez Castor de Cerqueira, Manoela 27 October 2014 (has links)
El sector eléctrico de muchos países pasó por un proceso de reestructuración que tuvo
su inicio en las décadas de los 80 y 90, cuyo objetivo era reorganizar el funcionamiento
del sector eléctrico, mejorando su eficiencia y proporcionando así beneficios a largo
plazo a los consumidores, como la reducción del precio de la electricidad. En España,
este proceso se inicia en la práctica con la aprobación de la Ley 54 del Sector Eléctrico
en 1997, que establecía las líneas generales de la reestructuración de las actividades del
sector y además marcaba como objetivo el 12% del consumo de energía primaria
proveniente de fuentes renovables en el año 2010. Esta ley también contenía un régimen
especial de apoyo a estas tecnologías basado en un sistema de primas. Este objetivo fue
un gran estimulo para el incremento de la participación de las renovables en la
estructura de generación del país, la cual pasó de representar el 2% de la potencia total
instalada en 1998 al 29% en 2012.
Teniendo en cuenta la situación de las renovables en España a lo largo del periodo de
reestructuración de su sector eléctrico, en esta tesis se propone averiguar el impacto
económico de estas fuentes de energía en el precio final medio de la energía eléctrica
durante este período. La herramienta seleccionada ha sido el análisis comparativo en
entornos similares para algunas variables y en entornos muy diferentes para otras, lo
cual debe permitir identificar el efecto de las variables de interés en el precio final
medio de la electricidad en el Reino Unido, California y Brasil junto con España.
En esta tesis se ha utilizado el precio final medio de la electricidad como parámetro para
valorar los efectos de la reestructuración del sector eléctrico en lugar de utilizar el
precio de la electricidad para consumidores domésticos o industriales, debido a que el
objetivo era analizar el comportamiento de esta commodity en el país como un todo y no
para una determinada clase de consumo. El precio final medio de la electricidad se
determinó considerando los costes reales de la energía eléctrica en cada ejercicio. Para
comparar este precio entre los distintos países se utilizó el purchasing power parity
(PPP) como factor de conversión del cambio de divisas para convertir los precios
nominales a dólares internacionales, además de ecualizar en el proceso el poder de
compra de los países considerados, eliminando las diferencias de nivel de precios entre
ellos.
Para el análisis propuesto se han recopilado datos procedentes de distintas fuentes,
abarcando un horizonte temporal de unos 30 años. La localización, verificación y
homologación de estos datos procedentes de fuentes muy diversas es uno de los
aspectos novedosos y fundamentales de esta tesis. A partir de estos datos se elaboraron
las curvas de precio final medio de la electricidad y de las variables que podían tener
alguna influencia en éste, para entonces establecer correlaciones entre el precio y cada
variable. La hipótesis de partida era que el aumento de generación renovable en España
había tenido una repercusión mensurable en los precios, mientras que en los países
comparados esta repercusión había sido insignificante, con lo cual, a partir del análisis
comparativo de las correlaciones encontradas entre las curvas de precio final medio de
la electricidad y las curvas de las variables identificadas, se segrega la influencia
específica de las renovables en la reestructuración del sector eléctrico español. / Martinez Castor De Cerqueira, M. (2014).

Gegenstand der Dissertation ist die Verantwortung der Kommunen für die Versorgung der örtlichen Bevölkerung mit Elektrizität: Woraus kann sie hergeleitet werden, welche Konsequenzen ergeben sich aus ihr für die Kommunen und welche Bedeutung kommt hierbei der Kooperation mit der Privatwirtschaft zu? Die in drei Teile gegliederte Arbeit befasst sich in ihrem ersten Teil mit den allgemeinen Grundlagen und der Entwicklung kommunaler Elektrizitätsversorgungsunternehmen. Im zweiten Teil geht es um die gesetzlichen Zielvorgaben in der Elektrizitätswirtschaft und die kommunale Verantwortung für ihr Erreichen. Der dritte Teil schließlich befasst sich mit den Voraussetzungen kooperativer Staatstätigkeit und dem Potenzial der Anwendung von Kooperationsmodellen im Bereich der örtlichen Elektrizitätsversorgung. / The dissertation ist focused on the responsibility of municipalities to supply local populations with electricity: Where can it be derived from, what consequences for municipalities arise from it and what role does the cooperation with private sector have in this context? The thesis is divided into three parts; the first part deals with the basic principles and the development of municipal electric utilities. The second part focuses on both statutory normative targets in the electricity supply industry and the municipality's responsibility to achieve them. Finally, the third part discusses the preconditions of cooperative government activity and the potential of cooperation models for application to local power supply.
