Abstract
There is a need for developing countries to transition to renewable energy systems to foster sustainable development and mitigate climate change impacts. Nigeria is pivotal in this transition because of its abundant renewable energy resources. This study aims to assess and design decentralised renewable energy systems in Nigeria using Hybrid Optimisation of Multiple Energy Sources software (HOMER), aligning with Sustainable Development Goal 7 (SDG7). Leveraging Decentralised Renewable Energy Systems (DRES) can address energy access gaps, reduce greenhouse gas emissions and foster socio-economic development in Nigeria, aligning with SDG 7 and other Sustainable Development Goals.This study adopted a mixed-method approach, incorporating quantitative energy data analysis and qualitative assessments through stakeholder interviews. Focusing on six cities in Nigeria`s six geopolitical zones interviews involved diverse stakeholders. NVivo, a qualitative data analysis tool, was used to analyse the interview transcript, and HOMER software was used to optimise and simulate potential renewable energy systems.
This study identified viable decentralised renewable energy solutions that are technically feasible and economically viable for each of Nigeria’s six geopolitical zones. HOMER simulations demonstrated that hybrid systems incorporating both solar and wind energy sources could meet the energy demands of the communities at a lower Levelised Cost of Electricity (LCOE) than conventional energy sources such as diesel.
The results indicate a promising pathway for Nigeria to enhance energy accessibility and sustainability through decentralised renewable energy systems. This research contributes to the growing body of knowledge on the practical implementation of SDGs through localised renewable energy strategies, offering a blueprint for other developing countries. This study acknowledges the limitations posed by the contextual differences between developing countries, the tools used for modelling, the case study context, and inherent uncertainties in renewable energy resource assessments.
The research underscores the potential of decentralised renewable energy systems in advancing sustainable development in Nigeria, demonstrating the feasibility of such systems in meeting energy demands sustainably and economically and answering the research question.
This research has provided recommendations and implementation guidance for developing decentralised energy systems using HOMER in response to SGD 7 in developing countries.
