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 →One of your own employees
The Regulations say the REM comes from your own staff. An outside REM is allowed only if they are Type 2, and only for up to three years from ST's notice. The registration and the practising certificate sit with the person, not the company.
See all five duties →REM Type 1 or Type 2: which one your site needs.
The Energy Efficiency and Conservation Regulations 2024 set two types of registered energy manager, and your site's energy use decides which one you appoint.
| Your site's energy use, any 12 consecutive months | Who you appoint |
|---|---|
| 21,600 to 50,000 GJ (about 6 to 13.9 GWh) | A registered energy manager of either type. Type 1 is enough. |
| Over 50,000 GJ (above about 13.9 GWh) | A Type 2 registered energy manager. |
| Type 1 | Type 2 |
|---|---|
| Who qualifies | |
| A degree in science, engineering, technology or architecture and two years' work experience, or a diploma and ten years. Registered graduate engineers, technologists and architects with two years, and professional engineers, technologists and architects, also qualify. | A Type 1 REM of at least one year with a valid practising certificate. A holder of a valid electrical energy manager certificate under the Electricity Supply Act 1990 can also sit ST's assessment, until that certificate expires. |
| From outside the company? | |
| No. Appointed from your own staff. | Yes, for up to three years from ST's notice. After that the role moves to an employee. |
| For both | |
| Show ST the knowledge of the Act and the Regulations it requires, and hold a valid practising certificate. | |
One REM on your staff can also carry the duties for up to seven related companies in your group (regulation 4). Source: the Energy Efficiency and Conservation Regulations 2024, P.U. (A) 466/2024, in force 1 January 2025.
What a Registered Energy Manager is responsible for.
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 efficiency
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 | First audit report due within 12 months of ST's notice, then every five years |
| To qualify | Type 1 or Type 2, see above | A degree and two years' experience or an equivalent registration, plus at least two energy audits approved by ST |
| 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. The qualifications for both roles are set out in regulations 14 and 15 of the Energy Efficiency and Conservation Regulations 2024.
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.
- Pick the person. The rule is someone on your own staff. If they have the background, the path is registration and a practising certificate with ST. Until your own person qualifies, a Type 2 REM from outside can hold the role for up to three years. 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.
