This paper is part of the ongoing research by the Power, Energy, Machine and Drive (PEMD) research group of the Electrical Engineering Department of the University of Ibadan. The paper presents various sites with possible hydrokinetic energy potential in Nigeria with the aim of quantifying their energy potential for rural electrification application. Overview of hydrokinetic technology is also presented with the view of highlighting the opportunities and the challenges of the technology for rural electrification. A case study of using hydrokinetic turbine technology in meeting the energy demand of a proposed civic center in a remote community is demonstrated.  Some of the key findings revealed that Nigeria has many untapped hydrokinetic potential site and if adequately harnessed can improve the energy poverty and boost economic activities especially in the isolated and remote rural communities, where adequate river water resource is available. The total estimated untapped hydrokinetic energy potential in Nigeria is 111.15MW with the Northern part of the country having 68.18MW while the Southern part has 42.97MW. The case study shows that harnessing hydrokinetic energy of potential site is promising for rural electrification. This paper is important as it will serve as an initial requirement for optimal investment in hydrokinetic power development in Nigeria.Article History: Received November 16th 2017; Received in revised form April 7th 2018; Accepted April 15th 2018; Available onlineHow to Cite This Article: Olatunji, O.A.S., Raphael, A.T. and Yomi, I.T.

At a global level, hydrokinetic power has been considered as a renewable energy source, and it has become an attractive alternative for the rural electrification of non-interconnected areas with the presence of water resources. Aspects such as the low rural electrification rate, the increase in energy demand, the decrease in fossil reserves and the climate change, are some of the factors that have driven the use of this technology for the electricity production. The aim of this work is to give a review of the hydrokinetic energy potential of water resources, the requirements and impacts of the implementation of hydrokinetic technology in different countries, and the current development in the Colombian case. At present, it can be observed that the implementation of this technology in different regions of the world, especially in Colombia, has several challenges and barriers, including gaps in knowledge, information and data, such as well as limitations of water resources and infrastructure, finally, impacting on a low adoption of this technology. On the other hand, publications on studies of implementation and potential of hydrokinetic technology have been increasing over time, indicating that this topic has been gaining interest despite the challenges.

The Given

It is a great challenge to identify optimum technologies for CHP systems that utilise biomass and convert it into heat and power. In this respect, industry decision makers are lacking in confidence to invest in biomass CHP due to economic risk from varying energy demand. This research work presents a linear programming systematic framework to design biomass CHP system based on potential loss of profit due to varying energy demand. Minimax Regret Criterion (MRC) approach was used to assess maximum regret between selections of the given biomass CHP design based on energy demand. Based on this, the model determined an optimal biomass CHP design with minimum regret in economic opportunity. As Feed-in Tariff (FiT) rates affects the revenue of the CHP plant, sensitivity analysis was then performed on FiT rates on the selection of biomass CHP design. Besides, design analysis on the trend of the optimum design selected by model was conducted. To demonstrate the proposed framework in this research, a case study was solved using the proposed approach. The case study focused on designing a biomass CHP system for a palm oil mill (POM) due to large energy potential of oil palm biomass in Malaysia.

This paper presents a method for estimating the solar capture capacity of dwellings using the central urban area of Concepción, Chile, as a case study in order to promote self-generation of energy by residents. The method takes into account the growing domestic energy demand and the possibility of meeting this demand through integrated solar energy collection into buildings using different systems. The methodology considers a study of the potential incoming solar radiation on buildings according to their geographical location and the surrounding buildings. The capacity for solar capture is then estimated for different dwelling types according to their morphology. Subsequently, the energy contribution provided by different technologies (solar thermal, photovoltaic and hybrid) is identified in relation to the main average energy demands for electricity, water and space heating. Finally, systems for each dwelling are recommended in an urban map available online. The development is based on climate information, cartography, aerial photographs, surveys, housing models, technical standards, standardised calculations and dynamic simulations, implemented according to building layouts from an online Geographic Information System (GIS). The housing types are categorised in an urban map that relates household demands and the contribution of different solar energy systems. According to the estimates calculated, the residential units in the study offer sufficient solar capacity to supply between 40 and 60% of their energy consumption, especially in detached houses using roof-mounted hybrid systems.

A feasibility study for the installation of Wave Energy Converters (WEC) in a Spanish Mediterranean port is evaluated in this paper. The final aim is to evaluate the possibility of building a new infrastructure which combines a breakwater and a WEC able to provide energy to the commercial port of Valencia. An estimation of the wave power potential is made according to existing databases from different sources. A review of the existing WEC types is carried out in order to choose the most suitable technology for its installation in a port environment. The authors discuss the main advantages and issues of the integration of WEC in port breakwaters. A prospective study for the Port of Valencia is made, considering the port energy demand evolution, historical data on wave energy potential and the port expansion plans. We conclude that Overtopping Devices (OTDs) are the most suitable ones to allow the good integration with the new breakwater needed for the expansion of the Port of Valencia and we give an estimation on the power available from the resource in our case study.

Improved Accuracy

The design of reliable and sustainable rural electrification systems relies on accurate prediction of the electrical load. This paper evaluates the current methods for load estimation and proposes an improved approach for load estimation for off-grid unelectrified rural communities that yields more accurate estimates. Improved accuracy is mainly due to better modelling of the influence of customer habits and gender on the estimated current and future load using the Markov chain process. A program was developed using MATLAB software to generate load profiles. The results show that gender considerations have a significant impact on load profiles and that the Markov chain process can suitably be used to determine year-to-year load profiles by incorporating the effect of changes in customer habits on the estimated load. The results from the case study on energy consumption in rural community households showed an increase in average daily consumption when gender was considered during load estimation. The peak consumption when gender was considered was about 50% higher than the value for when gender was not considered.

Rural electrification in Nepal is supported mostly by bilateral donors and banks as a top down supply driven activity with emphasis on generation and transmission, but not focusing on supplying electricity to the maximum number of rural people. In the past, rural electrification was awarded as political favors, leading to inefficiency. Further, it could not further the efficient development of energy, which requires marketing innovation. The result of such rural power distribution created a condition where everybody was at fault and a loser. An innovative approach involving the rural communities has the potential of reversing this trend, and allowing communities themselves to manage local rural electrification systems. This approach has raised public interest in Community Development and Rural Electrification with the establishment of about 450 rural electricity communities in Nepal. In anticipation, these communities are willingly contributing 20% matching fund of total rural electrifi cation cost. Since 2003 to 2008, 189,770 households (about 45,000 households annually) have gotten access to electricity in rural areas through the promotion of community-based electricity development. Clearly, this is a signifi cant positive response from the rural population. Like community forestry before it, community rural electrifi cation is also a success story in Nepal. The new approach has paved the way to gender equality. It helped to generate more economic activities, to activate productive end use of electricity, developed rural entrepreneurship and released the poorest of poor population from the ‘bonds’ of the old social structure.Hydro Nepal: Journal of Water, Energy and Environment Issue No. 4, January, 2009 Page 36-39

India currently has the biggest unelectrified population in the world. Renewable-based microgrids could provide a sustainable solution to providing universal energy access. However, the potential electricity demand in rural areas is unknown and hard to predict. This data is needed to analyse the purchasing power and potential market for microgrids, and to assess their success rate. This study surveyed 73 households in Arunachal Pradesh and Uttar Pradesh in India, to study the energy need in rural communities. The data shows that many unelectrified households are already using electrical appliances powered by small photovoltaic panels or batteries. The consumption is not income-generating but potential productive use cases are widely present. In Uttar Pradesh, small-scale microgrids are already providing homes with enough power for lighting and mobile chargers. An average unelectrified household was found to consume 2.48 kWhe monthly, and to spend ₹ 155 on energy services. Villagers wish for more appliances and more power, and have the required finances to pay for it.

Abstract This paper analyzes the historical trends in the energy supply and demand for the Macrometrópole Paulista Energy System, as well as the existing options for harnessing the renewable energy potential of the region. The research included a case study covering the 174 municipalities that belong to the macro-metropolis to characterize the energy system from 2006 to 2017 while analyzing the CO2 emissions of the system. The results indicated that, in 2017, the Paulista macro-metropolis accounted for 73% of the total energy demand of the entire state of São Paulo. Moreover, considering the energy generated from within the administrative limits of the 174 municipalities, the macro-metropolis accounted for about 17% of the total installed capacity of the state for electricity generation. This study found that the installed capacity for electricity generation in the region can be increased by ~ 112%. There so, an understanding of the local energy systems is of utmost importance for the formulation of coherent and integrated public policies, which are necessary to cope with the effects of climate change.

The current phase of the sustainable development of production is primarily focused on innovation and environmental products and services, and on greening the economy through the implementation of standardized tools (according to ISO). The paper presents the application of results of ongoing research through case studies under particular conditions. We have expanded our previously proposed business model as an input/output transformation system, presented in our previous research that was published at the 18th International Scientific Conference “Globalization and Its Socio-Economic Consequences” in Zilina and supported by the fact that we are co-creators of STN EN ISO standards 14051:2012 (839051) and STN EN ISO 14045:2013 (839045). Here, it is supplemented by the proposal of a procedure for selecting an instrument for greening the economy according to the area of economic activities (NACE coding). The methodological principles and the proposed procedure are applied through a case study in a small car repair company.

Mobile money in Zimbabwe has extensively extended the frontiers of financial inclusion to reach millions who were earlier excluded within a relatively short space of time. The growing use of mobile phones in transferring money and making payments has significantly altered the countrys financial inclusion landscape as millions who had been hitherto excluded can now perform financial transactions in a relatively cheap, reliable and secure way. The FinScope results found out that 45% of the adult population use mobile money services. Of those using mobile money, 65% mentioned that is convenient, while 36% mentioned that it is cheap. Mobile money is accessible. These drivers are in the backdrop of few or no bank branches in rural communities as well as time and cost of accessing the bank branches. In Zimbabwe, mobile money is mostly used as a vehicle for remittances. While some people are enjoying mobile money services, it is important to mention that there are still people who are excluded from the formal financial system. The reasons why people do not use mobile money are mainly related to poverty issues. Mobile money remains a viable option to push the landscape of financial inclusion in Zimbabwe and other emerging markets where the formal financial system might not be strong.
