Recent research published in the Iranian Journal of Electrical and Electronic Engineering highlights the potential of grid-connected photovoltaic (PV) systems to enhance energy reliability and sustainability for commercial consumers, specifically in the context of a food processing company in Ilorin, Nigeria. The study, led by A. O. Issa from the Department of Electrical and Electronics Engineering at the University of Ilorin, presents a comprehensive analysis of an optimally sized PV system that integrates with existing grid infrastructure.
The research addresses a critical issue faced by many businesses in regions where utility power supply is inconsistent. By implementing a grid-connected PV system, the Mount Olive food processing facility aims to provide a more reliable electricity supply while also benefiting economically and environmentally. The findings indicate that such a system can significantly reduce energy costs, with a calculated cost of energy at $0.136 per kilowatt-hour and a net present cost of $254,469.
One of the most compelling aspects of the study is the potential for commercial opportunities through net metering. The system is projected to generate an excess of 13,264 kilowatt-hours of electricity annually, which could be sold back to the grid, creating an additional revenue stream for the business. “This not only improves the financial viability of the project but also contributes to a more sustainable energy model,” said Issa.
The environmental benefits are equally noteworthy. The research reveals that transitioning from a grid/diesel generator system to a grid/PV/battery storage solution could reduce carbon dioxide emissions from 124,480 kg per year to just 10,081.6 kg. This dramatic decrease highlights the potential for renewable energy systems to mitigate climate change impacts, making them attractive not only from an economic standpoint but also in terms of corporate social responsibility.
The study also included a sensitivity analysis, examining how variations in load changes, grid power prices, and scheduled outages could affect the optimal system’s performance. This aspect is particularly relevant for businesses looking to invest in renewable energy, as it emphasizes the need for adaptable solutions that can withstand fluctuations in energy demand and supply.
Overall, the research underscores the growing importance of renewable energy systems in commercial sectors, particularly in regions where traditional power sources are unreliable. As businesses look for ways to reduce costs and enhance sustainability, the integration of grid-connected PV systems presents a viable and attractive option.
