“…Many households will experience diminished access to communication, healthcare, and academic services. In addition, higher electricity losses may severely depress the proftability of the utility companies and hinder new investment in the sector [8,10]. Te results of this study will have signifcant energy policy implications in South Africa to sufer lower electricity losses, maintain the current capacity, and avoid plunging the country into further crises.…”

The increased electricity demand amidst inadequate electricity generation in South Africa has plunged the country into frequent power outages and load shedding. However, the country still has the lowest electricity transmission and distribution losses in sub-Saharan Africa. Despite low losses, there is still an opportunity to reduce losses further and reduce power outages and load shedding. This study examines the determinants of electricity transmission and distribution losses in South Africa. The results will inform policymakers on avoiding higher electricity transmission losses to alleviate the current electricity shortfall. Using the time-series data from 1971–2020 and the autoregressive distributed-lag (ARDL) bounds testing approach to cointegration, the study confirmed a long-run relationship between electricity transmission, distribution losses, and income, price, investment, political regime, and economic integration. Regression analysis from the ARDL methods revealed that investments, political administration, and economic integration positively influence electricity transmission and distribution losses. At the same time, income reduces electricity transmission and distribution losses in the long run. However, income, price, and economic integration minimize electricity transmission losses in the short run while the remaining variables maintained their positive effects. The implication is that without proper checks in place, an expansion in South Africa’s economic integration, investment, and democracy may negatively affect the electricity sector of the country through an increase in electric power losses, while higher income will help the industry via lower electric power losses. The paper, among other things, recommends building a robust economy to ensure lower levels of electricity transmission and distribution losses.

“…Conway, et al [28] presented the future projection impact of increased climate change anomalies on South Africa's EWF resources, which will decrease annual precipitation by 20% by the 2080s, reducing water availability and crop yields. Disequilibrium in energy and water resources management depressingly disturbs the country's demand for electricity in Ghana [29].…”

Decoupling Energy, Water, and Food Resources Production from GHG Emissions: A Footprint Perspective Review of Africa from 1990 to 2017

et al. 2021

Decoupling energy, water, and food (EWF) consumption and production from GHG emissions could be an important strategy for achieving the UN Sustainable Development Goals (SDGs), especially SDG 2 (Zero Hunger), SDG 6 (Clean Water and Sanitation), and SDG 7 (Clean and Affordable Energy) in Africa. This study applies Tapio’s decoupling method to analyze the relationship between GHG emissions and EWF resources use in 15 African countries over the period 1990–2017. The results show a remarkable relationship, which includes the contamination of EWF by GHG emissions, that mostly exhibits unsatisfactory decoupling state to satisfactory decoupling over a period of several years. The decoupling of water and energy resources from GHG emissions in most countries of Africa has not been able to reach an excellent decoupling state or a strong positive decoupling state. This requires countries in Africa to support environmentally friendly water and energy infrastructures and to promote an integrated, mutually managed, whole resource interaction system. The study also highlights the importance of tracking sources of GHG emissions, whether within individual resource sector activities or across resources to each other.

“…Developing countries, over the past few decades, have adopted one form of pricing model or the other. For example, India uses Availability Based Tariff (Rai et al, 2013), Ghana employs End -User Tariff (Adom et al, 2019), Saudi Arabia implements Time-of-Use Tariff (Mahmood et al, 2010) and Nigeria adopts Multi-Year Tariff Order (Tallapragaada, 2009). Irrespective of the differences in model, the bottom line is to have affordable, reliable and sustainable electricity supply.…”

This study investigates stakeholders' perception of the sustainability of Nigeria's MYTO pricing methodology vis-à-vis government's electricity efficiency objectives. Using a five-point Likert questionnaire, data was collected and analysed via descriptive and regression analyses. The results indicate that 96% of the variations in electricity pricing is accounted for by government's electricity efficiency objectives of acceptability, accessibility and availability. The study concludes that Nigeria's MYTO pricing regime is sustainable. Similarly, the study concludes that there is policy inadequacy in addressing fundamental issues of end users' lack of awareness of pricing system and mistrust between industry players. Although these conclusions have met the objectives of the study, the study recommends further research on the impact of subsidy on sustainability of electricity pricing methodology.
