In an innovative leap for renewable energy, a recent study led by Ubong Ukommi from the Department of Electrical and Electronic Engineering at Akwa Ibom State University, Nigeria, has unveiled the design and performance analysis of a 500KVA pumped water energy storage solar power plant specifically tailored for university campuses. This research, published in the ABUAD Journal of Engineering Research and Development, offers a blueprint for sustainable energy solutions that could significantly impact the energy sector, particularly in educational institutions.
The study focuses on the Akwa Ibom State University Main Campus, where the need for reliable, sustainable energy sources is paramount. With daily energy demands reaching 9,600 KWh, the research team devised a system that integrates solar photovoltaic (PV) modules and pumped hydro storage to ensure a continuous power supply. “The careful combination of direct supply and pumped water storage is needed to optimize the system efficiency,” Ukommi emphasized, highlighting the intricate balance required for such a renewable energy setup.
The proposed system features an impressive array of 11,458 solar PV modules, each rated at 300 watts, culminating in a total capacity of approximately 3.4 MW. This ambitious project not only meets the campus’s energy demands but also aims to provide three days of power autonomy through a pumped water storage reservoir with a capacity of over 413,000 cubic meters. The design incorporates 40 parallel pumps, each with a flow rate of 0.1342 m³/s, showcasing a robust engineering approach to harnessing renewable resources effectively.
The efficiencies reported in the study are noteworthy: the solar power segment operates at 63.5%, while the hydro power segment achieves 70.7%. However, the combined efficiency of the solar-hydro plant stands at 44.9%, indicating room for improvement and optimization. “This research not only addresses the immediate energy needs of the university but also sets a precedent for future developments in renewable energy systems,” Ukommi stated, underlining the broader implications for energy management in similar institutions.
The potential commercial impacts of this research extend beyond the university campus. As educational institutions increasingly seek sustainable solutions to their energy challenges, this model could serve as a scalable template for other universities and organizations. The integration of solar energy with pumped hydro storage not only enhances energy security but also contributes to reducing carbon footprints, aligning with global sustainability goals.
As the energy sector continues to evolve towards greener alternatives, the findings from Ukommi’s research could catalyze further innovations in renewable energy technologies. By demonstrating the viability of such systems in a university setting, it paves the way for broader adoption in various sectors, reinforcing the role of education in driving sustainable energy initiatives.
