Solutions · Energy Monitoring

See every kilowatt, the moment it moves.

You can't manage, or report, what you can't see. KERO meters every energy-using system into one live view, so waste shows up in real time instead of arriving a month late on a bill.

Most sites still run blind. The building-management system shows one slice, the utility bill arrives weeks after the energy was spent, and nobody can say which machine is wasting what, right now. EECA 2024 makes that gap a liability: you can't audit or report what you never measured.

What you get

One live view of everything that draws power.

Real-time

Live dashboards

Consumption, demand, power factor and cost, per system and site-wide, updating as it happens, not at month end.

Granular

Per-system sub-metering

Chillers, HVAC, compressors, pumps, boilers and solar, each metered separately, so you know exactly where the kilowatts go.

Proactive

Alerts & thresholds

Get notified the moment a load drifts, demand spikes, or power factor slips below target, before it compounds into cost.

Demand

Peak & power factor

Watch maximum demand and power factor in real time, the two charges that quietly inflate an industrial bill.

Unified

One source of truth

Every meter, every site, one platform. No reconciling spreadsheets against a BMS against a bill.

Compliant

Audit-ready records

Continuous logging builds the evidence an EECA energy audit needs, automatically, in the background.

Maximum demand

Your peak has an hour and a machine behind it. Your bill has a number.

Time of Use windows on TNB’s non-domestic tariff, read from mytnb.com.my on 12 September 2026
PeriodHoursDays
Peak2:00pm to 10:00pmMonday to Friday
Off-peak10:00pm to 2:00pmMonday to Friday
Off-peak24 hoursSaturday and Sunday
TNB, on the Time of Use tariff expansion For non-domestic medium voltage and high voltage customers, “Maximum Demand which occurs during Off-Peak period will not be charged.”

So a peak set at three in the afternoon and a peak set at eleven at night are different money. A monthly bill gives you one number for the whole month with no hour attached to it, which leaves the question a plant engineer actually needs answered, what started when, and alongside what, to guesswork.

Interval metering answers it. KERO meters the main incomer and each system separately and keeps the record running, so a peak arrives with a timestamp and a name on it: the compressor that started at 14:40, the chiller that came on beside it. From there, moving a start time is an operating decision somebody makes on Monday, with the figure to check it against on Tuesday.

Power factor sits in the same place. It is visible continuously, which is what lets an alert fire while it is still a drift.

Where the meters go

An energy monitoring system for factories in Malaysia: where each meter goes, and what it answers.

The count follows the question. Every load you may have to answer for separately gets its own meter, and the rest sits under the incomer.

Choosing one for a Malaysian plant

Circuit level, not site level
A single site meter gives a total. Attribution starts at the circuit, which is where a drift has a machine attached to it.
Demand and power factor as they happen
Both are charged, and both are set inside an interval. Seeing them at month end leaves nothing to act on.
A record an auditor accepts
Continuous, timestamped, and kept. The EECA 2024 energy audit, the energy management system and the report to Suruhanjaya Tenaga all describe energy that was measured while it was being used.
It reads the plant you already run
Existing meters, drives and building systems from the usual brands, so metering is added rather than replaced.
Energy per unit of production
Consumption alone moves with output. Energy against units made is the number that shows whether the plant is improving.
People sign, software supplies
Your Registered Energy Manager and auditor carry the duties under the Act. What a monitoring system owes them is complete evidence, on time.

Common questions

Energy monitoring on a Malaysian plant, answered.

What should an energy monitoring system measure on a factory site in Malaysia?
The main incomer, then each major system separately, so consumption is attributed load by load: compressed air, chillers and cooling loops, motors and drives, boilers and steam, and any rooftop solar. On top of that, maximum demand and power factor in real time, because both are charged, and a continuous record with timestamps, because that is what an EECA 2024 energy audit and the reporting to Suruhanjaya Tenaga are built from. KERO is an energy monitoring system for factories in Malaysia built around exactly that list. What it looks like on a plant floor →
When is maximum demand charged in Malaysia?
On TNB’s Time of Use tariff the peak window runs 2:00pm to 10:00pm, Monday to Friday. Everything outside it is off-peak, and Saturday and Sunday are off-peak for all 24 hours. TNB states that for non-domestic medium voltage and high voltage customers, maximum demand occurring in the off-peak period is not charged. Read from mytnb.com.my on 12 September 2026, and worth checking against your own tariff category, because those windows belong to the Time of Use tariffs.
How do I find out what set my maximum demand?
Meter below the incomer and record continuously. A single site meter gives you the peak figure and leaves its cause open, so the coincidence behind it, two large loads starting inside the same interval, stays invisible. With each system metered separately and logged, the peak has an hour, a duration and the loads that were running into it, which is the point at which staggering a start becomes a decision you can defend. See it on a site like yours →
How many meters does a factory in Malaysia need?
As many as the questions you have to answer separately. One on each incoming supply for the site total, maximum demand and power factor; one on each switchboard feeder worth separating; then the loads that move the bill, compressors, chillers, drive panels, boilers, and any production line you report on. Everything else sits under the incomer. A site that only wants the monthly total needs one meter, and that meter will never say which machine set the peak. The metering plan, point by point →
Does energy monitoring help with EECA 2024?
It is what the rest of the Act stands on. The energy audit, the energy management system and the EE&C report to Suruhanjaya Tenaga all describe energy you have already measured, so a site that starts metering early reaches each deadline with the evidence already collected.

The foundation EECA 2024 is built on.

Every duty the Act sets, the energy audit, the energy management system, the reporting to Suruhanjaya Tenaga, depends on measurement. Monitoring isn't a nice-to-have alongside compliance; it's the thing compliance stands on. Get the metering right and the audit, EnMS and reports largely write themselves.
