GSO Power Clean Energy Transition • Case Study

Location: University of Nigeria, Nsukka (UNN), Nigeria

Capacity: 240kW PV / 483kWh ESS (512V 945Ah)

Completion / Groundbreaking: March 2024 / May 2024 Delivery

Executive Summary: Transforming Campus Power Infrastructure

Reliable electricity is the backbone of modern higher education, yet many institutions across Sub-Saharan Africa struggle with unstable grid electricity and soaring diesel generator maintenance costs. A shining beacon of sustainable transformation is emerging at the University of Nigeria, Nsukka (UNN), where a groundbreaking 240kW/483kWh (512V 945Ah) Solar-Plus-Storage Car Park Project has officially been deployed.This system is designed and produced by GSO, providing customers with a very cost-effective high-pressure energy storage system.

The Challenge: Overcoming Energy Barriers in Nigerian Academia

For decades, the Faculty of Engineering at UNN faced persistent hurdles with conventional power supplies from the Enugu Electricity Distribution Company (EEDC), compounded by frequent grid outages and heavy reliance on expensive fossil-fuel generators. High monthly electricity tariffs and unstable voltage severely disrupted laboratory experiments, computer-based research, and daily administrative operations.

We consider the pain points of our customers and use our GSS high-voltage series products specifically. We collect electricity through a daytime solar system and provide electricity services to schools at night to solve the electricity problem. Only the Bms system can provide customers with sufficient electricity usage, effectively saving the school’s operating costs.

Engineering Innovation: Dual-Purpose Solar Canopy & Smart Storage

Rather than mounting solar panels on conventional building roofs—which often present structural and cabling limitations—the project team engineered an innovative solar canopy car park spanning four distinct car park ports with a total capacity of 80 vehicles.

This design delivers a triple advantage:

• Dual-Use Real Estate: Converts standard surface parking lots into active green power generators without taking up valuable campus land.

• Vehicle Protection: Provides shaded parking, shielding faculty and visitor vehicles from intense tropical equatorial sunlight.

• Optimized Energy Flow: Combines daytime photovoltaic generation for immediate self-consumption with a robust 483kWh energy storage system that captures surplus solar energy, ensuring uninterrupted nighttime and peak-hour power supply.

  Strategic Impact: Economic, Environmental, and Academic Benefits

  The successful delivery of the 240kW/483kWh solar-plus-storage system delivers profound multi-dimensional benefits across the university ecosystem:

  Economic Savings

  By shifting a substantial portion of daily daytime electrical loads to solar power and utilizing stored battery energy during peak tariff periods, UNN achieves massive reductions in grid electricity expenditure. These savings can be redirected toward academic research, laboratory upgrades, and student welfare.

  Environmental Sustainability

  As Nigeria pursues its national commitments toward net-zero emissions and Sustainable Development Goals (SDGs), this project directly displaces thousands of metric tons of carbon dioxide annually, substituting diesel generator emissions with zero-carbon solar electricity.

  Conclusion: A Blueprint for Africa’s Green Campus Revolution

  The Azura Power & UNN 240kW/483kWh solar car park project stands as a benchmark for public-private partnerships and renewable energy integration across African tertiary institutions. By pairing high-performance solar generation with intelligent energy storage, UNN has charted a clear path toward energy resilience, operational cost reduction, and environmental stewardship.

  As commercial and industrial (C&I) entities across Sub-Saharan Africa look for proven frameworks to beat energy poverty, pioneering projects like UNN demonstrate that solar-plus-storage is not merely an alternative—it is the definitive future of sustainable infrastructure.
