Energy monitoring — the flagship
Energy monitoring measures every point where cost is made
A utility bill gives one total for the whole site. It does not say which transformer, department, machine or floor is responsible for it, or which hours of the day the cost was incurred in. Sub-metering answers both, permanently. It is the first of the three services Orijtech offers, and the record it produces is what a solar design and an energy audit are then built on.
What a single monthly total leaves out
Your bill arrives 30 days late
By the time you see the total, the cost is already sunk. There is no ability to intervene mid-month, and no way to tell an operational decision from a fault.
You see a total — not the source
One line on a bill conceals dozens of loads: chillers, production, laundry, theatres, lighting, tenant boards, offices. Cutting any one of them means isolating it first, and a department can only be held to a consumption target it can actually see.
Capital decisions made on estimates
Transformer upgrades, solar investments, tariff reviews and expansion plans all require load data that most facilities simply do not hold.
What management receives
Every deliverable is written for the people who approve spending as well as for the engineers who read the panels.
Live consumption dashboard
Department by department, machine by machine, refreshed every 5 seconds and stored at 1-minute intervals. Accessible on any device.
Monthly cost attribution report
Which areas drove the bill this month, against last month and against the same period last year — in UGX, not only in kWh.
Anomaly and peak alerts
Notifications when consumption crosses agreed thresholds, so a stuck contactor or an overnight plant left running is caught in hours rather than at month end.
A verified history for capital decisions
Continuous consumption history to support solar sizing, transformer capacity checks, tariff reviews and equipment investment cases, with the readings behind each figure available to anyone reviewing the case.
A deployment on record
- Meters installed
- 19
- Current sensors
- 57
- Read continuously since
- May 2023
At Jesa Farm Dairy in Busunju, sub-metering covers the New and Old Plant transformers and the major loads behind them. Nineteen three-phase meters take three current sensors each, and the record they have built since May 2023 is what every subsequent decision at the site has been argued from — the solar sizing, and the processing hours.
What the record was then used to decideFour meter tiers, selected by load
The tier follows the current at the point being measured. A lighting board and a main incomer do not get the same instrument, and fitting the larger one everywhere adds cost without adding a single reading.
| Tier | Current rating | Current sensor | Typical application |
|---|---|---|---|
| Light Tier | Up to 100A per phase | 100A split-core current transformer, 13mm | Lighting and socket distribution boards, small pumps, small office loads |
| Medium Tier | Up to 600A per phase | 600A split-core current transformer, 32mm | Lifts, boilers, compressors, HVAC panels, floor distribution boards |
| Heavy Tier 1000 | Up to 1000A per phase | 1000A Rogowski coil, 100mm | Transformers, main incomers, large chillers, large feeders |
| Heavy Tier 2000 | Up to 2000A per phase | 2000A Rogowski coil, custom larger diameter | Very large transformers, high-capacity industrial incomers |
Three sensors per meter
Every three-phase meter requires exactly three current sensors — one per phase. Where a quotation shows fewer, the missing phases are being estimated from the ones that are measured, and any imbalance between them disappears.
One gateway per location
Meters in the same electrical room share a gateway. Separate buildings, or floors with poor connectivity, need their own. Gateways are mounted centrally, where cellular coverage is reliable and wiring runs stay short.
Sizing confirmed on site
Tier selection in an assessment is based on expected load and the electrical information available. Final sensor sizing is confirmed against the actual conductor or busbar during installation, and we state that as an assumption every time.
From order to handover
The programme below is the one written into the delivery schedule. Roughly 15 working days from order placement to commissioning sign-off, inside a three-week purchase-order lead time.
Site assessment comes first and is separate: a survey of your electrical infrastructure producing a written metering proposal — monitoring points, tier per point, gateway count and rationale.
Days 1–9
Procurement and preparation
Equipment ordered against the agreed specification, supplier acknowledgement, provisional installation dates and isolation windows agreed with your engineering team, then goods receipt, inspection and bench-testing of meters and gateways before anyone mobilises to site.
Days 10–12
Mobilisation and installation
Safety induction and permit to work, then mechanical installation at each point: DIN-rail enclosures, isolators, trunking, voltage taps, and three current sensors per meter with orientation and phase mapping verified. Brief planned isolations are needed at each point.
Day 14
Power-up and configuration
Readings verified, phase rotation and sensor direction checked, meters paired to their gateway, connectivity confirmed, dashboards configured and every monitoring point labelled with the name your team already uses for it.
Day 15
Data-integrity check and handover
A 24-hour data-integrity check, functional tests on alerts and reporting, snag closure, then commissioning sign-off witnessed by your nominated engineering representative and handover of the as-installed record. Baseline data collection starts immediately.
What runs on this data
These are capabilities inside energy monitoring, not separate products. They read the same meters, on the same platform, and each one gets better as more of the facility is measured.
Energy reporting and analysis
Monthly and quarterly reports that turn the interval data into findings, financial impact and recommended actions for management.
Power quality
Voltage behaviour, phase imbalance and power factor read from the same measurement points, with the correction case quantified from the readings.
Utility bill verification
Independent meter records reconciled line by line against what the utility billed, so a discrepancy can be demonstrated with figures.
Generator fuel monitoring
Diesel consumption, runtime and refills on the same platform, so grid and generator cost sit in one picture.
One of three service lines
The interval data these meters produce is what a solar array is sized against and what an energy audit’s findings are checked back to. If the monitoring is already in, neither of those has to start by measuring the site again.

A site assessment produces a complete written metering proposal: what to monitor, why, which tier, how many meters and gateways, and what the data will show you.
