Energy Issues in Nigeria's Private Sector
Nigeria's grid is notorious for unreliability—with daily blackouts, zany voltage, and costly diesel. A number of businesses, mainly Lagos and Abuja supermarkets, are spending a lot of money on generators with fuel costs up 60% in recent years. Businesses lose revenue during outages, and customers become annoyed.
How Off-Grid Solar Battery Storage Delivers Value
An Off-grid Solar Battery Storage System integrates solar panels, lithium-ion energy storage batteries, PCS inverters, and EMS intelligence into one modular container. Specifications often look like this:
| Component | Specification |
|---|---|
| Energy Storage Container | 10ft container |
| Battery Capacity | 645 kWh high-density lithium-ion pack |
| Inverter / PCS | 300 kW bi-directional converter |
| Performance | 1C charge/discharge rate, AC-coupled architecture |
| EMS Control | Automatic switching, real-time monitoring |
This setup allows daytime solar generation to feed loads directly and store surplus energy for night or cloudy weather—providing uninterrupted power 24/7.
Real-World Case: Nigerian Supermarket Breakthrough
In Nigeria, a leading supermarket chain in the nation commissioned a 10-foot containerized BESS and combined it with a rooftop solar array to create an extremely autonomous power solution. The system is equipped with 645kWh of battery capacity and 300kW of photovoltaic PCS, and it achieves fully off-grid standalone operation.
Implementation Results
- Use rate of auto-generated power has increased to an impressive 95%, drastically reducing dependence on external energy.
- Elimination of diesel generators altogether reduces fuel costs, not to mention avoiding noise and exhaust fumes.
- The cost of running has been drastically reduced, and overall running costs have dropped more than 60%.
- Silent operation and zero pollution atmosphere enhance customer satisfaction and worker work environment.
- The system ensures the supply of electricity throughout the day, essentially bypassing running interruptions due to power failures, and increasing customer confidence and goodwill.
- In addition to extending business hours, it also pushes the development of operating income further.
Additional Proven Scenarios in Nigeria
Similar models have been adopted successfully across Nigeria:
- ATESS commissioned a hybrid solar mini-grid in Ogun State for over 10,000 users. A 1 MW PV field and 1.7 MWh battery system provided round-the-clock power to residential, school, and commercial loads.
- Academic modelling of the load of a Port Harcourt supermarket (~59.8 kW/day) found that a solar + battery + backup solution vastly outperformed power from a sole generator, both in terms of cost and emissions savings.
Benefits at a Glance
- Reliable Power: Eliminates outages and disruptions during business hours.
- Lower Lifetime Cost: Return on investment usually within 2–4 years when grid and generator expenses are included.
- Environmentally Friendly: Zero-emission operation, satisfying sustainability goals.
- Energy Autonomy: Less reliance on national grid; incremental capacity additions possible.
- Ease of Deployment: Modular containers quickly installed, minimal on-site civil work.
