EECA 2024: what the law requires, and how to comply.
Malaysia's first dedicated energy-efficiency law now binds every large energy user. If your site uses 21,600 GJ, about 6 GWh, or more a year, the clock is already running. Here is exactly what you must do, by when, and how KERO does the monitoring, audit and reporting it takes.
EECA 2024, the Energy Efficiency and Conservation Act 2024 (Act 861), is Malaysia's first standalone energy-efficiency law. In force since 1 January 2025, it requires large energy users to appoint a Registered Energy Manager, run energy audits, operate an energy management system, and report to Suruhanjaya Tenaga (ST). It applies in Peninsular Malaysia and the Federal Territory of Labuan, and it replaced the 2008 electrical-energy regulations.
The duties and penalties sit in Act 861; the specific figures, the 21,600 GJ threshold and the 3- and 12-month deadlines, are prescribed by its regulations, the Energy Efficiency and Conservation Regulations 2024 (EECR 2024). This page walks through both, in plain terms.
Are you in scope?
EECA 2024 applies to a registered energy consumer: any site whose total energy use reaches 21,600 GJ in any 12-month period, counting every source, electricity, gas, diesel, everything.
21,600 GJ ≈ 6 GWh ≈ 6,000,000 kWh / year
One gigajoule is about 277.8 kWh. The line works out to roughly a mid-to-large factory, shopping mall, hospital or campus. It is measured across any 12 consecutive months, not a calendar year, so a site can cross it mid-period.
Use the in-scope checkerEnergy-intensive sites, across every sector
Manufacturing plants, commercial buildings, industrial facilities, data centres, hotels and hospitals all routinely sit above the line. If you run continuous process loads, chillers, compressors or large HVAC, you are very likely in scope.

Once you are a registered energy consumer and Suruhanjaya Tenaga issues its notice, fixed clocks start. Miss them and each lapse is a separate offence.
Appoint a Registered Energy Manager (REM)
A licensed professional who takes responsibility for your energy audits, energy management system and reporting. What an REM needs →
Complete your first energy audit
A structured assessment of where energy goes and where it is wasted, then repeated roughly every 5 years. How an energy audit works →
Establish an Energy Management System (EnMS)
An ongoing system, shaped around ISO 50001, for measuring, managing and improving energy performance. What an EnMS requires →
Report to Suruhanjaya Tenaga
Your EE&C report goes in through EMIS, the Commission’s online system: the first one within 30 days after your REM has been in post a year, then every year on that same anniversary. This is where most of the recurring effort sits, and where software earns its keep. How EMIS filing works →
Re-audit, and keep improving
Compliance is not a one-off. Audits repeat, the EnMS runs continuously, and reporting never stops. Deadlines & penalties in full →
Every report goes into one system, and one step unlocks the rest.
Suruhanjaya Tenaga runs EECA 2024 through EMIS, the Energy Management Information System at emis.st.gov.my. The Commission issues the logins. What catches sites out is the order, because two separate clocks are running and only one of them starts on the day your notice arrives.
- Day 0 Your notice arrives from ST
- + 3 months Registered Energy Manager appointed
- + 12 months First energy audit report filedThen every 5 years
- + 12 months EnMS submitted to STEnergy policy, committee, and the signed copy approved by top management Unlocks the next step
- + 12 months and 30 days First EE&C report filedThen every year, within 30 days of the same anniversary
The Commission is explicit about the order: for an energy consumer, EMIS opens the EE&C report only once the EnMS has been submitted. Those two sit thirty days apart. A site that treats the EnMS as paperwork to finish later finds it is the thing standing between it and a report that is already due.
| What gets filed | Prepared by | Approved by | Submitted to ST by |
|---|---|---|---|
| Energy management system (EnMS) | Your REM, or you | You | You |
| EE&C report | Your REM | You | You |
| Energy audit report | Your REA | You | You |
Look at who submits. Your REM and your REA prepare the work, and every one of those submissions is made by the person in charge of the premise. Appointing good people covers the preparing. The filing, and the clock on it, stays yours.
The cost of getting it wrong.
Act 861 attaches real penalties to the energy-consumer duties, and they apply per offence, so lapses stack.
KERO does the measuring, auditing and reporting.
The law assigns the manager and auditor roles to people. KERO gives those people the live data, the audit trail and the ST-ready reports, so your reporting is complete, accurate and on time. It never sits the exam for you.
| EECA 2024 duty | What it involves | How KERO helps |
|---|---|---|
| Know if you're in scope | The 21,600 GJ / 6 GWh test, across 12 months, all sources | Meters every energy source and totals your annual use, so you always know where you stand against the line. |
| Support your REM | A licensed manager, within 3 months of notice | Gives your Registered Energy Manager live dashboards, alerts and a full audit trail from day one. |
| Run energy audits | First audit within 12 months; repeat every 5 years | Continuous sub-metering and analytics replace manual spot-checks, the audit evidence is already there. |
| Establish an EnMS | ISO 50001-aligned, within 12 months of REM appointment | The EECAMS and ISO 50001 (ISOMS) modules structure your energy data the way an EnMS expects. |
| Report to ST | Ongoing, structured, auditable reporting | EECAMS produces ST-ready reports on schedule, complete and on time, not rebuilt by hand each cycle. |
