Registered Electrical Energy Manager: REEM to REM Guide

A Registered Energy Manager (REM), the role formerly known as the Registered Electrical Energy Manager (REEM), must be appointed within three months of Suruhanjaya Tenaga (ST) issuing your written notice of designation under the Energy Efficiency and Conservation Act 2024 (EECA). Designation itself is triggered once your site's total energy consumption, from all sources combined, not just electricity, reaches 21,600 GJ over any 12 consecutive months. Miss the appointment window and the Act allows fines against the company; the REM, once appointed, carries separate legal duties and can be penalised individually for failing them.

In short

• Designation threshold: 21,600 GJ of total energy consumption (all fuels, not just electricity) in any rolling 12-month period.
• Appointment deadline: 3 months from ST's written notice of designation.
• EECA 2024 applies in Peninsular Malaysia and Labuan only; Sabah and Sarawak are developing their own separate frameworks.
• Two consumption bands above the threshold decide which REM competency tier your site needs; check the exact bands and current fine amounts with ST or a REM consultant, since these are set by regulation and can be updated.

What EECA 2024 actually requires

The Energy Efficiency and Conservation Act 2024, in force since 1 January 2025, requires any site consuming 21,600 GJ or more of total energy, electricity plus fuels like diesel, LPG or natural gas combined, in a rolling 12-month window to register as a designated consumer with ST. Once designated, you have three months to appoint a Registered Energy Manager, who then becomes responsible for energy efficiency and conservation reporting and, where required, energy audits for that site.

Is there a "Type 1" and "Type 2" REM?

Yes. ST registers REMs at two competency tiers, commonly called Type 1 (REM T1) and Type 2 (REM T2), with the tier your site needs set by which consumption band you fall into: roughly 21,600 GJ up to 50,000 GJ a year for the lower tier, above that for the higher tier. If your site sits near either boundary, confirm the current band definitions with ST, since the exact cutoffs live in subsidiary regulations that can be revised.

Can our chargeman act as the REM?

Not automatically. A chargeman is registered under the Electricity Regulations 1994 for electrical installation safety and operation, a different competency and a different legal basis from the REM role under EECA, which covers energy efficiency and conservation reporting. Your chargeman could pursue REM registration separately if they meet the qualifying criteria, but holding one registration does not confer the other.

Does EECA 2024 apply in Sabah and Sarawak?

No. EECA 2024 currently applies to Peninsular Malaysia and the Federal Territory of Labuan. Sabah runs its own, separate EREEM scheme under its own Energy Commission; a site there is not designated under EECA 2024, though it may carry an equivalent obligation under Sabah's own framework.

What if our consumption drops below 21,600 GJ after we're designated?

Designation does not lapse automatically the moment consumption dips for one period. In general regulatory practice, a designated consumer stays designated until it formally notifies ST and demonstrates sustained lower consumption, so treat a one-off drop as a reason to review your position with ST rather than assume you are no longer covered. Confirm the exact de-designation process directly with ST, since a single below-threshold month is unlikely to be sufficient on its own.

How do we verify a consultant's REM certificate?

ST runs public verification portals: eecaverify.st.gov.my/rem-t1 for Type 1 registrations and eecaverify.st.gov.my/rem-t2 for Type 2. Check a consultant's registration number there before appointing them; a REM appointed without a valid, verifiable registration does not satisfy the Act.

Is an AEMAS Certified Energy Manager the same as a REM?

No. The AEMAS Certified Energy Manager (CEM) is a separate, ASEAN-recognised professional certification and is not itself a REM registration under EECA 2024. A CEM qualification can commonly be used as one pathway toward meeting REM competency requirements, but the REM appointment itself still has to be registered with ST specifically under the Act.

Getting your reporting data ready

Whoever holds the REM role needs equipment- and energy-source-level data to prepare a credible efficiency and conservation report, not just the annual TNB total. Sites that already sub-meter their major loads and fuel use have a head start on this; see our guide on EECA compliance in Malaysia for what the reporting itself covers, and our ISO 50001 vs EECA comparison if you are weighing both frameworks together.
