A Review of the Causes of Sustainable Supply Deficiencies in Natural Gas Supply in Ghana

Although Ghana produces natural gas and has several gas reserves, the country still depends on supplies from neighbouring countries for power generation due to challenges like fuel supply inefficiencies and increasing cost of gas production. Gas supply is thus a limiting factor for power generation. This study explores strategies to improve gas supplies for sustainable power generation in Ghana. The study examined the underlying factors inhibiting gas supplies in Ghana, investigated the risks in the gas supply industry, and explored strategies for improving gas supplies in Ghana. The study adopted an inductive approach that utilises both qualitative and quantitative research methods. With the use of questionnaires, data were collected from 151 respondents who were selected by purposive and snowball sampling procedures. The collected data were descriptively and inferentially analysed with analytical tools in the SPSS. The study’s findings conclude that factors that inhibit gas supply in Ghana include the lack of growth and supply investment in the gas supply industry, power sector debt on the gas market, and the lack of an extensive distribution infrastructure/network. Also, the gas industry in Ghana lacks the requisite investment drive which culminates into inefficiency and ultimately undermines efforts to achieve sustainable power generation. Politics influence in issues relating to gas supplies in Ghana inhibits long-term supply relationships and permanent infrastructure in gas supply, both locally and on the world market.

Managing System Losses to Improve Energy Efficiency within the Electricity Company of Ghana (ECG) Limited

The inability to achieve the target of universal access to electricity is influenced by several factors including funding limitations, the use of obsolete equipment, power theft, and system losses confronting the electricity distribution services of the Electricity Company of Ghana Limited (ECG). The study assessed the components of system losses within the ECG by determining and computing the percentage of system losses within ECG, examining the causes of both commercial and technical losses in ECG, and determining ways to improve energy efficiency by reducing system losses in the most cost-efficient manner. The study adopted deductive reasoning and a quantitative approach to guide data collection and analysis of the research output. A sample of 345 technical and non-technical staff of ECG in the Greater Accra Metropolis was selected from a population of 2500. Purposive, simple random, and cluster sampling techniques were used in identifying and accessing respondents for the study. Descriptive statistics were applied to measure central tendency and degrees of dispersion and the Relative Importance Index (RII) to predict criterion and predictor variables. The impact of low voltage network losses can adversely contribute to technical losses (20%) and reduce energy efficiency in power or electricity distribution companies. Non-technical losses are mainly caused by illegal connections, meter problems, and billing problems. Each of the non-technical losses contributes a maximum of 10% to system losses. Contributors to system losses at ECG are ranked first for power theft and least for lack of incentives. System losses at ECG include metering inaccuracies, bad workmanship, unmetered supply, and lengthy distribution lines, each recording a mean value of above 3.5. Measures to improve monitoring of the networks and systems at ECG and discourage power theft should include an extensive quantification, patrolling, and inspection of the entire network to assess the extent of the network and conditions relevant for the placement of systematically planned maintenance programmes.

Mitigating the Environmental Effects of Oil and Gas Exploitation: Issues of Compliance, Cost of Production, and Community Awareness

This study assessed the effectiveness of mitigation measures adopted to address the environmental effects of oil and gas industries from the perspective of compliance, cost of production, and community awareness. The research applied a case study through multi-method-qualitative and quantitative approaches. The target population of 547,368 people involved people in Takoradi, Shama and Newtown communities. A sample size of 150 was selected and categorised under 36% for Shama, 30% for Newtown and 34% for Takoradi. A combination of probability (simple random) and non-probability (cluster and convenience) sampling frames were used to access the respondents for the study. Data collection tools were limited to questionnaires and interview sessions. The descriptive statistics, Relative Importance Index (RII) and significance testing using a one-sample t-test module guided the analysis. Interview sessions were compiled into transcripts and later categorized into themes that directly reflected the patterns of the questions on the questionnaire. The conclusion rated major decisions in mitigating oil and gas impacts on the environment as first for conscious effort to package fuel and other chemicals in safe storages, followed by the use of best road systems to reduce the risk of accidents, then application of strict rules and regulations to curb impacts and lastly capacity building for participants in the oil and gas production industry. While significant measures have been adopted to mitigate the effects of oil and gas exploration, there remain challenges with effectiveness as a result of weakness in community involvement efforts, lack of motivation, weak laws and regulations and loss of respect. For effectiveness in reducing the challenges to mitigate the environmental impacts of the oil and gas production activity, policymakers, as well as the practitioners in the oil production industry, are advised to motivate people into buying into their policy to reduce such impacts.

Differential Impacts of Wind Energy on Sustainable Power Generation in Ghana

Ghana has a yearly development interest for power at a rate of 83.8% in 2010, and to 12% from 2020 to 2040 but this opportunity has been farfetched with the shocks in energy generation during 1983, 1994, 1997-98, and 2006-2007 era pushing the energy sector into crisis and a consequent adverse impact of 1.5% to GDP. This study, therefore, investigated the differential impacts of wind energy to sustainable power generation in Ghana by assessing the determinants of energy supply, energy demand and supply mix for energy development, the capacity of the energy sector to develop wind power and possible challenges in developing wind power energy in Ghana. An exploratory design that adopted both qualitative and quantities approaches was applied to the study. The study population involving 34 sample sizes was accessed from a 46 population made up of management/ministers of energy and counsellors or energy experts. The study concluded that the demand for energy in Ghana has increased over the years but without a commensurate increase in energy supply. Major reasons for the shortfall in energy supply have centred on the monopoly enjoyed by the major power producer which invariably places stress on its ability to supply energy to meet the increasing demand. It also came out that wind energy has the potential to contribute to the overall energy fortunes of Ghana. However, a focus on wind energy may not produce the required results of reducing the energy supply gap due to a preference for solar and natural gas oils. It was also noteworthy that the need to build capacity to develop and maintain wind energy through critical, current infrastructure stance of the Ghanaian energy sector would not make this agenda of developing wind energy a reality. More so, it is important to note that the need to enhance the current weak national policy, financial backing and bridge technology gap for wind energy would be needful to realise a vibrant investment into wind energy development.

An Analysis of Influencers of Energy Security for SMEs in the Greater Accra Region of Ghana

Investments in the exploitation of the continent’s raw material reserves have resulted in little (positive) impact on the energy security situation within Africa. This paper attempts to explore factors influencing the level of energy security of Small Medium Enterprises (SMEs) in the Greater Accra Region of Ghana, and from the dimension of availability, affordability, economic efficiency and environmental stewardship or sustainability of energy. The cross-sectional survey design was employed as the design for the collection and analysis of data. The study applied a quantitative research method in examining the indicators of energy security for SMEs in Accra Metropolis in the Greater Accra Region of Ghana. The population covered about 500 SMEs who have about 100 employees and total revenue of $1 million or the equivalence in Ghana Cedis. A sample of 246 was selected through a cluster and simple random sampling. The analysis adopted statistical techniques to conduct descriptive, exploratory and inferential analysis of the data collected. Factors that influence the level of energy security of SMEs are broadly categorized into the environment and economic change, political factors, physical disruptions and market conditions. Ge- nerally, the level of energy security under the availability dimension is medium among the SMEs. Issues of affordability, economic efficiency and environmental stewardship provide high medium interventions on energy security for SMEs. It is recommended that managers of Ghana’s energy sector should ensure prudent management of the country’s energy resources since the disruption of supply lines or sources form the key conditions that influence the energy security level of SMEs. SMEs should adopt energy efficiency measures to ensure that energy is conserved for future use.
