The Registered Energy Manager, and the 3-month clock.
When a Suruhanjaya Tenaga notice lands, your first legal duty has a deadline measured in weeks: appoint a Registered Energy Manager within three months. Here is who an REM is, what they're accountable for, and how KERO makes their job doable.
A Registered Energy Manager (REM) is the individual a large energy user must appoint to take charge of energy under EECA 2024. They are registered with Suruhanjaya Tenaga (ST) and hold a valid practising certificate, and they become your accountable point for energy audits, your energy management system, and reporting to the regulator.
The duty sits in the Energy Efficiency and Conservation Regulations 2024 (EECR 2024). Once ST issues its notice to a registered energy consumer, the appointment must be made within three months — and a missed appointment is an offence in its own right.
If you're in scope, you need an REM.
The trigger is the same threshold that brings the whole Act to your door: a site over the 21,600 GJ line, once Suruhanjaya Tenaga has issued its notice.
A registered energy consumer, on notice
If your site uses 21,600 GJ (about 6 GWh) or more across any 12 consecutive months, you are a registered energy consumer. When ST issues its notice, the 3-month clock to appoint an REM starts.
Check if you're in scope →An employee, or someone you engage
The REM can be a suitably qualified member of your own staff who registers with ST, or an external professional you appoint. Either way, the registration and the practising certificate sit with the person, not the company.

The REM is the human owner of your EECA obligations. The law gives them a clear remit — and most of it runs on data they need at their fingertips.
Oversee the energy audit
Make sure the site's first energy audit is completed on time and acted on, working with a Registered Energy Auditor. How an energy audit works →
Run the energy management system
Establish and maintain the EnMS — the ongoing system, shaped around ISO 50001, for measuring and improving energy performance. What an EnMS requires →
Report to Suruhanjaya Tenaga
Prepare and submit the energy reports ST requires, on schedule — consumption, management measures and improvements, complete and on time.
Be the liaison with the regulator
Act as the named point of contact between the site and ST, and keep the records that back up everything you report.
Drive the savings
Beyond compliance, the REM is positioned to find and chase the waste — the part of the job that pays for itself.
Energy Manager vs Energy Auditor.
EECA 2024 deliberately separates the person who runs your energy management from the person who independently audits it. It's easy to conflate them — don't.
| Registered Energy Manager | Registered Energy Auditor | |
|---|---|---|
| What they do | Run ongoing energy management, the EnMS and reporting | Independently conduct the energy audit |
| When | Appointed within 3 months of ST notice; ongoing | Engaged to complete the first audit within 12 months; repeats periodically |
| Registered with | Suruhanjaya Tenaga, with a practising certificate | Suruhanjaya Tenaga, with a practising certificate |
| Relationship to you | Your accountable owner for energy | An independent check on your energy use |
Some organisations appoint one qualified individual able to act in a registered capacity; many engage separately. Confirm the exact registration categories and qualifications with Suruhanjaya Tenaga.
How to appoint one in time.
- Confirm you're in scope and note the date. The three months run from the ST notice — log the deadline the day it arrives. Check your figure first if you haven't.
- Decide in-house or external. If someone on staff has the background, the path is registration and a practising certificate with ST. If not, line up a qualified external REM early — good ones get busy as deadlines cluster.
- Verify registration with Suruhanjaya Tenaga. The person must be properly registered and hold a valid practising certificate. The Commission sets the qualifications and renewal requirements.
- Give them the data on day one. An REM with live metering, a clean audit trail and report-ready data starts ahead. An REM handed a folder of monthly bills starts behind.
KERO equips your REM. It doesn't replace them.
The law assigns this role to a person — and KERO is software, so it can't hold the certificate. What it can do is make the REM's job fast, defensible and continuous instead of a monthly scramble.
One real-time view
Every meter and source on one dashboard, so your REM always knows where energy is going — not where it went last quarter.
Evidence, already gathered
Continuous sub-metering builds the record an audit needs as it happens, so nothing has to be reconstructed by hand.
ST-ready, on schedule
The compliance modules turn that data into structured reports for Suruhanjaya Tenaga — complete and on time, not rebuilt every cycle.
