Will the Anchor Hold? An Overview of the Financial Performance of the Electricity Company of Ghana (ECG) from 2009 to 2012

Ghana has been plagued with Power Crisis for the past three years. In the mix of discussions on the energy challenges that Ghana has been confronted with over the years is the level of efficiency of its sole electricity distribution organisation; the Electricity Company of Ghana Limited (ECG). Whiles some experts have called for the contracting of the management of the ECG in order to make it much more efficient and profitable, others have advised that the company should be totally privatised. Proponents of the latter stance argue that this would enable the ECG run more efficiently and attract the necessary investments which would employ efficient technologies in the distribution of power for industry and households. This feat is necessary especially considering that Ghana has committed to universal access to electricity in year 2020. This paper focuses on analysing the financial performance of the Electricity Company of Ghana from 2009 to 2012 by the use of financial ratios. In nutshell, results from the ratios are used to advise on the best ways to make the ECG an efficient organisation in delivering on its core mandate to the citizenry of Ghana.

An Exploratory Study of Effects of Prepaid Metering and Energy Related Behaviour among Ghanaian Household

The focus of the study is to examine the effect of a new billing and payment system (prepaid meters) by Electricity Company of Ghana (ECG) on the efficiency of revenue mobilization, its impacts on expenditure of several households groups and the behaviour of the consumers. Based on a survey of 384 households from the Ho municipality in the Volta Region of Ghana, our empirical analysis suggest the utility provider experiences a significant increase in its revenue after the introduction of prepaid metering system. However, the study did not find any difference in the expenditure between single and compound households. Furthermore, there was a strong shift by consumers towards energy conserving attitude and behaviour.

Using a Fixed and Switched-Capacitor Bank to Investigate Harmonic Resonance and Capacitor Bank Switching in a Distribution Network

Harmonic resonance often manifests as high harmonic voltages in a power system. This produces losses and affects other consumers in the grid negatively. Capacitance switching applications also involve not only interrupting capacitive currents, but also the energizing of capacitor banks, cables and overhead lines. The applications of capacitors are extensively used in power systems for voltage support and power factor correction. However, the main concern arising from the use of capacitors is the possibility of system resonance. This study investigates the frequent capacitor bank tripping and damages in one of the distribution substations of the Electricity Company of Ghana (ECG). The study was conducted using the Electromagnetic Transient Program (EMTP) software for the simulation. The results showed that, the failures were related to harmonic resonance. Selected series connected inductors were recommended to shift the resonant frequencies of the network below characteristics harmonic frequencies.

Power Quality Analysis in a Distribution Network of a Quarry Processing Plant

Power quality problems encompass a wide range of different phenomena. Each of these phenomena may have a variety of different causes and different solutions that can be used to improve upon the power quality and equipment performance. This paper analyses the malfunctioning of a capacitor bank at a quarry processing company (QPC) in the Western Region of Ghana. The QPC had held the Electricity Company of Ghana (ECG) responsible for the damage. According to QPC, the damage was due to frequent power fluctuations and outages experienced from the ECG distribution network. The paper presents and discusses techniques used to investigate the cause of the problem. The result of the analysis of the damage was conducted using the electromagnetic transient programme (EMTP) and relates the damage to harmonic resonance produced from the QPC power distribution network. It is recommended that, for reliable, safe and economic operation of capacitor banks, the harmonic content of an electrical installation is measured and analyzed before installation.

Performance Management in Public Sector Enterprises: A Case Analysis of Employees’ Perceptions in the Electricity Company of Ghana (ECG)

In this article, the authors critically assess the performance management (PM) policies and practices in a public sector company, namely the Electricity Corporation of Ghana. The study has gone some way to ‘close the gap’ in the literature by making a significant contribution toward our understanding of some of the perceptions of and challenges employees face with performance management in an African context. Quantitative analysis of available evidence reveals that employees are generally content with the implementation of the PM system in the Electricity Corporation of Ghana but are skeptical about some of the practices under the guise of PM.
