Case Study - Public Utilities
The Power Solutions Unit at Stag Engineering Nigeria Limited has a long track record of delivering high-impact energy projects across the country. With every project, we meet complex specifications while ensuring compliance with environmental standards, local regulations, and international best practices.
Landmark Project: LVDS to HVDS Conversion (11kV Network – LUTH Clusters)
One of our most notable achievements is the conversion of low-voltage distribution systems (LVDS) to high-voltage distribution systems (HVDS) on the 11kV network at LUTH clusters.
Electricity remains the engine of industrialization, technological growth, and national development. This conversion project was part of a World Bank initiative, introduced under the Commercial Re-Orientation of Electricity Sector Toolkit (CREST) and funded through the National Energy Development Project (NEDP) a credit facility from the International Development Association (IDA) of the World Bank.
Key Benefits of LVDS to HVDS Conversion
The project was designed to enhance distribution efficiency and customer satisfaction by addressing critical challenges:
Reduced technical & commercial losses and fewer transformer failures
Minimized energy theft due to smaller LT (Low Tension) networks with smaller-capacity transformers
Lower maintenance costs and improved system reliability
Stable tail-end voltage, improving customer power quality
Better energy and peak load management through customer segmentation
Increased revenue base for the distribution company
Project Achievements
337 transformers (25 kVA) and 494 transformers (50 kVA) installed and commissioned
11,447 customers connected and serviced
First commissioning: October 2007, at Falolu Area (OKOH Feeder) and Sam Shonibare Area (OGUNLANA Feeder)
Customers in these areas have since enjoyed stable, reliable electricity supply with significantly improved service delivery
