A Photovoltaics and Battery-Based End-to-End Direct-Current Power Network for Community Solar

Eliminating fossil fuel as early as possible and electrifying everything by green sustainable electric power are some of the primary solutions for tackling the climate emergency. Solar electricity generated by photovoltaics is now the cheapest source of electric power generation. The cost of electrochemical storage batteries is plummeting and the combination of photovoltaics and batteries at a utility scale can provide a lower cost than electrical power generated by fossil fuel in many parts of the world. Thus, today, we nearly have a solution in sustainable green electrical power generation and storage. Globally, we have adopted alternating-current electric power infrastructure over direct-current power due to the invention of the transformer. However, due to the advancements in power electronics and loads based on semiconductors, the situation is totally different today. Except for induction motors running at rated speed, all loads using variable-frequency drive are direct-current loads. Photovoltaics, batteries, and virtually all loads are based on direct-current power. Considering power generation, transmission, distribution, and utilization as a single entity, we are wasting a large amount of power by using our alternating-current power electricity infrastructure. By using end-to-end direct-current power networks, we can save energy and capital investment in electricity infrastructure as well as the cost of the loads, as compared to the existing power infrastructure. Based on an end-to-end direct-current power network, a new concept for community solar is proposed in this paper. Without connecting to the existing grid, community solar can provide 24 × 7 electric power to residents. The proposed infrastructure concept can also have a transformative role in areas which are providing very high growth of green electric power. This concept can have an immediate profound impact on any new constructions in most parts of the world.

Energy poverty in light of the climate emergency in Sub‐Saharan Africa: Impact and transmission channels

AbstractThis study analyzes the effect of energy poverty on environmental quality for a sample of 43 countries in sub‐Saharan Africa. We specify and estimate a linear panel data model for the period 2000–2021, using fixed effects and the Driscoll‐Kraay method. The results show that access to electricity and clean energy for cooking have a positive and significant effect on deforestation and carbon emissions. Taking into account non‐linear analysis, we find that there is an inverted U‐relationship between energy indicators and environmental quality, thus, verifying the hypothesis of the Kuznet environmental curve. Thus, access to electricity and access to clean cooking energy improve environmental quality from a threshold. For the resolution of endogeneity, Lewbel 2SLS, the Kiviet method and S‐GMM were used. In addition, analysis of the sample data using a structural equation model (PLS‐SEM) shows that energy indicators pass through various channels to affect environmental quality. Therefore, based on these results, we recommend increasing investments in electricity infrastructure, especially in clean decentralized energy, in order to reduce deforestation and, therefore, CO2 emissions.

The Effect of Electricity Supply on the Performance of Small and Medium-Scale Enterprises in Nigeria: A Case Study of Calabar South and Calabar Municipality of Cross River State

This research work analyzed the comparative study of the effect of electricity supply on the performance of small and medium-scale enterprises in Calabar South and Calabar Municipality,using small and medium scale businessmen and women as well as power holding company staff. The objectives of this study to analyze the comparative study of the effect of electricity supply on the performance of small and medium-scale enterprises in Calabar South and Calabar Municipality.The survey research design was adopted and a twelve (12) item structured questionnaire was used to obtain a sample size of 248 small and medium scale business owners and power holding staff randomly selected from the population. The results of the study revealed that there is a significant effect of electricity supply on the performance of small and medium-scale enterprises in Calabar South and Calabar Municipality. The results further revealed that insufficient electricity supply significantly affect the performance of small and medium-scale enterprises in Calabar South and Calabar Municipality.The study concludes that there are enormous difficulties being experienced by businesses in Cross River State and other parts of Nigeria due to inadequate and unreliable electric power supply. Thus an inadequate and unreliable supply of electricity imposes costs and therefore constrained firms’ operational performance as firms suffer high overhead cost due to the deficient electricity supply from the national grid. The study recommends that the Nigerian government needs to consider the issue of power supply reliability very seriously by facilitating both private and public investment in electricity infrastructure.

Leveraging private investment to expand renewable power generation: Evidence on financial additionality and productivity gains from Uganda

Effectively mitigating climate change entails a quick upscaling and redirection of electricity infrastructure investment towards clean power. Given that the bulk of greenhouse gas emissions increases until 2050 will come from low- and middle-income countries, finding cost-effective ways to mitigate climate change while meeting development targets is essential. However, recent research has shown some of the limitations of broad financing mechanisms, such as the Clean Development Mechanism (CDM) and existing carbon markets. This has resulted in a growing interest in designing novel investment support schemes, such as modifications of feed-in tariffs (FiTs) that may be more cost effective and better targeted towards particular outcomes when compared to traditional deployment subsidies or broad financing mechanisms. We evaluate the design and outcomes of one such novel support schemes: the GET FiT (Global Energy Transfer Feed-in Tariff) investment support scheme in Uganda, which has attracted ~ 453 million USD in private sector investment for 17 small-scale renewable energy projects (solar, hydro, bagasse) in only three years. Using financial modelling on detailed project-level data, we find that most projects were additional and would therefore not have been built without the subsidy. In addition, using firm-level panel data, we show that power outages hamper manufacturing performance in Uganda. In the absence of reliable outage-data for the entire Ugandan territory, we use nightlight variations to proxy changes in outages. We show that outages have declined substantially since the introduction of GET FiT. Yet, our analysis also demonstrates that programmes to incentivise additional renewable generation in developing countries funded internationally or domestically should liaise closely with grid authorities to ensure that supply does not outstrip demand.

Examining the Relationship Between Electricity Consumption, Economic Growth, Energy Prices and Technology Development in India

This article examines the empirical relationship between electricity consumption, economic growth, energy prices and technology development for India by taking annual time series data from 1981 to 2017. By using the ARDL bounds testing approach to co-integration, the study found long-run equilibrium relationship does exist among the variables. The article reports the existence of positive and significant impact of economic growth on electricity consumption, whereas technological development negatively affects electricity consumption in both the long run and short run. The Granger causality results reveal the presence of unidirectional causality from economic growth and technological development to electricity consumption in India. Therefore, the present study suggests policy makers in India to increase investment in electricity infrastructure to support high economic growth in the country. Further, the policy makers and the government should encourage more technological innovation to minimise usage of fossil fuels and support the use of green energy. This action could help the economy achieve a sustainable economic growth with better environmental quality. JEL Codes: C22, O4, O13, Q43, Q48

The Electrical Reliability Plan: A Tool to Bridge Business Strategy With Electrical Investment

Maintaining reliability for electrical distribution systems that support processing facilities is a constant challenge due to aging equipment and other factors. Upgrades and replacements require significant engineering, extensive capital, scheduling, and shutdowns. Investment in electrical infrastructure is often marginalized and only addressed upon an unplanned failure or necessary expansion. Without an overall comprehensive strategy, it is difficult to ensure that these expenditures meet the facility?s business objectives and contribute to long-term value. An electrical reliability plan (ERP) is a tool that helps align business strategy with capital investment.

Electricity Consumption, Corruption and Economic Growth

An important prerequisite for reducing poverty, sustainable development and achievement of the millennium development goal has to some extent been tied to access to electricity. However, the subject matter; 'electricity consumption causing economic growth' has seen conflicting results from the theoretical and empirical front, if indeed a relationship exist at all.
 The study tests, within a panel context the long-run relationship between electricity consumption and economic growth for 13 African Countries from 2006 to 2017 by employing recently developed panel co-integration techniques. Implementing a three stage approach made up of panel unit root, panel co-integration and Granger causality test to examine the causal relationship between electricity consumption, electricity price, corruption, employment and growth.
 The study provides empirical evidence that a bidirectional causal relationship between electricity consumption and economic growth exist in the short run, suggesting that lack of electricity could hamper economic growth as well as an investment in electricity infrastructure would in turn improve economic growth. Also reveals that corruption causes the level of electricity consumption and GDP in the short run. On the long-run front electricity consumption and electricity price granger causes GDP and GDP causes electricity consumption.

Evaluation of Investments in Electricity Infrastructure Using Real Options and Multiobjective Formulation

The electrical sector has become highly competitive introducing new levels of uncertainty. In response to this situation, assessment methods and investment projects need to evolve in order to incorporate different uncertainties in the planning process and to consider adequately the multiple objectives of a competitive environment. This paper discusses an analysis method which possesses the above mentioned characteristics taking an approach based on real options, which permits the evaluation of investment alternatives in multi-objective applications to be made. This provides project administrators with a tool to decide which objectives need higher consideration within the planning process. The method proposed is applied to a case study on a Mexican electricity system and considers the objectives for maximising economic profit while minimis-ing economic loss due to reliability and power quality issues in the electricity supply.
