Background

A national restaurant chain in Nigeria operates multiple high-demand sites in regions across Lagos. Frequent outages and oversized diesel generators led to high energy costs, inefficient operations, and difficulty in justifying renewable investments without clear performance data.


Objective

To reduce energy costs, improve operational efficiency, and gather the data needed to support renewable energy adoption while maintaining reliable power across all sites.


Methodology
 

enee.io deployed plug-and-play IoT sensors across the chain's energy assets, including generators and grid inputs. The system provided:

• Live data tracking via web and mobile dashboards

• Detailed energy profiles for each site

• Automated alerts for proactive maintenance

• Comparative analysis to identify underperforming locations

Findings
 

The analysis showed:

• 165kVA generator operating at <25% capacity, wasting fuel

• Significant phase imbalance between electrical loads

• Opportunity to replace existing generator with smaller, more efficient unit

• Solar PV could meet 25% of site demand, cutting annual costs by ₦18M

Action Taken

​

• Replaced 165kVA generator with an 80kVA unit for optimal load efficiency

• Corrected electrical phase imbalance to reduce component wear

• Used enee.io data to secure the case for 30kWp solar PV installation

​

Results
 

• ₦10 million annual savings from generator right-sizing

• ₦18 million projected annual savings from solar PV

• ROI on enee.io monitoring system <1 month

• Solar project ROI 23–26 months with finance options to avoid upfront costs

• Reduced diesel generator runtime, fuel consumption, and maintenance needs
