What we do
Energy monitoring, solar project development and energy audits, on one measured record
Orijtech Energy meters your building, designs solar from what those meters actually record, and audits energy performance against the same evidence. We work in hotels, factories, banks, hospitals, campuses and government buildings, on sites of 50 kW to 2 MW peak demand.
Measurement comes first, because everything else depends on it
- 01
Meter the building
Sub-meters at the transformer incomer, the distribution boards, and the loads that matter — chillers, compressors, laundries, lifts, production lines, tenant feeders. Every three-phase meter takes three current sensors.
- 02
Build the record
Readings refresh every five seconds and are stored at one-minute resolution. Within a month you hold a verified consumption history by department, by hour and by tariff band.
- 03
Decide from it
That record is what a solar design is sized against, what a tariff or billing dispute is argued from, and what an audit finding rests on. Without it, all three decisions are taken on an estimate.
Energy monitoring
Permanent sub-metering across your facility, a live platform management can open on any device, and a reporting cadence that turns the data into decisions. This is the flagship, and it is the part the other two offers run on.
- Measured at every point
- Voltage · Current · Active, reactive and apparent power · Power factor · Frequency · Phase loading · Load profile · Demand behaviour
- Resolution
- Five-second refresh, one-minute cloud records, full consumption history retained.
- Time-of-use bands
- Off-peak, shoulder and peak reported separately, so the bill can be attributed to the hours that caused it.
Meter tiers and how each point is selected
Tier is set by the current the point actually carries. Final sensor sizing is confirmed on site during installation.
| Tier | Rating | Typical points |
|---|---|---|
| Light Tier | Up to 100A per phase | Lighting and socket boards, small pumps, office loads |
| Medium Tier | Up to 600A per phase | Lifts, boilers, compressors, HVAC panels, floor boards |
| Heavy Tier 1000 | Up to 1000A per phase | Transformers, main incomers, large chillers and feeders |
| Heavy Tier 2000 | Up to 2000A per phase | Very large transformers and high-capacity industrial incomers |
Every three-phase meter requires three current sensors. One gateway serves each physical monitoring location; meters in the same electrical room normally share one.
Energy reporting and analysis
Monthly and quarterly reporting: time-of-use analysis, period comparison, abnormal consumption, and the recommendation attached to each finding.
Power quality
Voltage stability, harmonics and phase imbalance — read from the meters already installed, before they damage motors and transformers.
Utility bill verification
Your own metered record, set against the utility invoice, tariff band by tariff band. Independent evidence for a billing dispute.
Generator fuel monitoring
Tank level, refuelling events, fuel drops and engine hours on the same platform as grid consumption.
Solar project development
We size and specify the system from your measured consumption, then manage the project on your behalf through delivery. A specialist installation contractor performs the physical build to our specification; the relationship, the technical brief and the verification stay with us.
How we develop a solar projectWhat we own
- Sizing from the metered daytime load profile, recorded across a full operating cycle
- The technical specification: array, inverter, protection, metering and monitoring integration
- Comparison of installer proposals against that specification, so bids are judged on the same brief
- Project management through the build, with your team as the single point of contact
- Verification after commissioning — generation measured against the same platform as your grid supply
At JESA, measured consumption showed the proposed array was larger than the site needed and UGX 300 million came off the investment before anything was bought.
Read the JESA case studyEnergy audits
Scoped to your site rather than sold as a package. An Orijtech audit is built on measurement, so every finding carries the data that produced it — which is what makes it survive a procurement review, an internal audit, or a board question.
Scope and inventory
Walk the site with your engineering team. Record the loads in scope, their ratings, operating hours, and the electrical topology feeding them.
Measurement period
Install metering — temporary or permanent — across the loads in scope and log through a full operating cycle, including weekends and shutdowns.
Tariff and bill analysis
Set the metered record against your utility invoices: consumption by tariff band, demand charges, any reactive or power factor line item the account carries, and any variance between billed and measured units.
Technical assessment
Transformer loading against rating, phase balance, power factor, voltage stability and harmonic content, plus load-scheduling opportunities visible in the profile.
Findings register
Every measure listed with its measured basis, the saving it is expected to deliver, what it costs to implement, and the payback period. Ranked, so the no-cost operational changes are separated from the capital items.
Report and presentation
A technical report your engineers can act on, an executive summary written for the board or accounting officer, and a walkthrough of both with the people who have to approve the spend.
Because scope varies by site, an audit is priced against an agreed scope rather than a standard rate. Tell us the buildings, the loads and the decision the audit has to support, and we will write the scope with you.
Energy audits in detailWhat the measured record has produced for clients
None of these were separate engagements. Each came out of a monitoring deployment that was already in place.
UGX 300M
cut from a solar investment
The proposal had been sized on estimated consumption. Measured demand was materially lower, so the system was re-specified before it was bought.
JESAUGX 100M
transformer purchase avoided
Sustained loading was inside the unit rating; only startup demand spiked. The replacement was cancelled on the metered evidence.
QCILUGX 36M
saved per year, no capital spend
Sub-metering traced a large share of the hotel bill to the laundry running in peak tariff hours. The fix was the shift schedule.
Sheraton KampalaHow an engagement runs
The same four stages whichever of the three you start with. Institutional and government buyers can lift this straight into a procurement schedule.
Site assessment
We survey the electrical infrastructure and return a metering plan: which points, which tier, how many gateways, and what each point is expected to tell you.
Proposal and scope
A written scope with quantities, assumptions stated openly, and the commercial terms. Final current-sensor sizing is always confirmed on site.
Installation and commissioning
Roughly fifteen working days from order to handover, including bench testing before mobilisation and a 24-hour data-integrity check before sign-off.
Reporting cadence
Baseline data, then the agreed reporting rhythm — monthly or quarterly — with a named analyst you can call directly.
What we need from your side
Stated up front so it can be planned into a shutdown window rather than discovered on the day.
- Safe site access and a permit-to-work route
- Agreed isolation windows at each metering point
- A gateway position with power and cellular coverage
- A nominated engineering representative to witness commissioning
Installation needs brief planned isolations at each metering point. Each window is agreed with your engineering team before we mobilise.
energy made easy
Every engagement begins with a site assessment
A site assessment tells you what to meter, why, and what each point is expected to reveal. It commits you to nothing beyond a walk around your own building with an engineer.
Or start by reading what the monitoring produces
A full monthly report with the client removed and the figures illustrative: the band split, cost by metered area, the load profile, the demand event that set the charge, the actions, and last month’s actions with their measured outcome.
