How Data Avoided a UGX 100M Transformer Purchase and Recovered UGX 40M in Overcharges

Background

Quality Chemical Industries Ltd (QCIL) — Uganda's largest pharmaceutical manufacturer — operates a large production facility in Kampala with significant and varied electrical loads. The facility runs 24 hours and draws power across multiple distribution boards serving production lines, HVAC systems, cold storage, and utility infrastructure.

Two separate concerns brought QCIL to Orijtech Energy. First, the facility's engineering team had received advice suggesting the main transformer was operating near its rated limit and would need replacement — a capital expenditure estimated at UGX 100 million. Second, management had reason to believe the utility billing did not accurately reflect actual consumption, but without independent metering data, there was no basis to challenge it.

What We Did

Orijtech Energy deployed smart energy meters at the main transformer incomer and across the facility's key distribution boards. The meters captured real-time load profiles — including demand peaks, load factor, and consumption by tariff period — and transmitted data to the Orijtech Energy cloud platform for analysis.

The monitoring ran continuously, capturing data across production cycles, shift changes, and weekend operating patterns.

What the Data Showed

On the transformer question: The metered load profiles showed that while instantaneous demand did spike during startup sequences, the transformer's sustained loading remained consistently within its rated capacity. The spikes were brief and well within thermal tolerance. There was no evidence of sustained overloading that would justify replacement.

On the billing question: The independent meter data, cross-referenced against the utility's invoices over a 12-month period, identified a material discrepancy in the applied tariff structure and recorded units. The variance amounted to UGX 40 million in overbilling.

Outcomes

Armed with verified metering data, QCIL made two consequential decisions:

1. The transformer replacement was cancelled. The engineering team's concern — while understandable without data — was not supported by the actual load profile. The UGX 100 million capital expenditure was avoided entirely.

2. The utility overcharge was formally disputed and recovered. With independent meter records as evidence, QCIL successfully recovered UGX 40 million in overcharges.

Total value created: UGX 140 million — from a monitoring deployment.

"The metering gave us the evidence we needed to make a confident decision — in both directions. We avoided spending money we didn't need to spend, and recovered money we were owed."
