Under the Energy Efficiency and Conservation Act 2024 (EECA 2024), an Energy Consumer whose total energy consumption reaches or exceeds 21,600 GJ within 12 consecutive months may be required to appoint a Registered Energy Manager (REM).
What is a REM, what does a REM actually do, which type is right for your organisation, and can you appoint one externally? Let's go through it step by step.

What Is a Registered Energy Manager (REM)?
A Registered Energy Manager (REM) is a person registered with the Energy Commission (ST) to help an Energy Consumer manage and improve its energy performance and meet relevant energy efficiency and conservation requirements.
The REM supports the organisation through activities such as monitoring energy use, analysing energy performance, implementing an Energy Management System (EnMS), preparing EE&C reports and identifying energy-saving opportunities.
In simple terms, a REM helps an organisation understand where its energy is being used, identify opportunities to improve efficiency, and keep track of its energy performance over time.
Why Does an Energy Consumer Need to Appoint a REM?
Under the Energy Efficiency and Conservation Regulations 2024, an Energy Consumer that meets the applicable energy consumption threshold is required to appoint a Registered Energy Manager (REM).
Once the Energy Consumer receives a written notice from the Energy Commission, the REM appointment must be made within three months from the date of the notice.
This is where many organisations begin to ask:
“Which type of REM do we actually need?”
Which Type of REM Does Your Organisation Need?
The applicable REM qualification depends on the Energy Consumer's energy consumption over 12 consecutive months.
Registered Energy Manager – First Type (REM Type 1)
REM Type 1 is applicable to Energy Consumers with total energy consumption of:
21,600 GJ – 50,000 GJ
Registered Energy Manager – Second Type (REM Type 2)
REM Type 2 is required for Energy Consumers with total energy consumption of:
More than 50,000 GJ
A REM Type 2 can also be appointed for Energy Consumers within the 21,600 GJ – 50,000 GJ range, meaning it can cover both energy consumption categories.
Does a REM Have to Be an Employee?
Under the Energy Efficiency and Conservation Regulations 2024, an Energy Consumer is generally required to appoint a Registered Energy Manager from among its employees.
However, an Energy Consumer may appoint an External REM who meets the requirements for a Second Type REM under Regulation 14(2) or 14(3).
The External REM appointment may be made for up to three years from the date of the Commission's written notice.
An External REM may also be appointed when an existing REM vacates the position and the Energy Consumer is unable to appoint a replacement from among its employees within three months, subject to the Commission's written approval under Regulation 7(3).
Looking for an External REM Type 2?
We support organisations with External REM Type 2 services, including EnMS implementation and EE&C Report preparation.
What Does a Registered Energy Manager Actually Do?
A REM is not simply appointed to fulfil a requirement.
The role involves supporting the Energy Consumer's ongoing energy efficiency and conservation activities.
01 — Collect & Analyse Energy Data
Collect and analyse energy consumption data to understand how energy is being used.
02 — Support EnMS Implementation
Support the Energy Consumer in developing and implementing its Energy Management System (EnMS).
03 — Monitor EnMS
Monitor the implementation of the EnMS and the organisation's energy performance.
04 — Prepare the EE&C Report
Prepare the Energy Efficiency and Conservation (EE&C) Report according to the applicable requirements.
05 — Ensure Report Accuracy
Ensure that the information included in the EE&C Report is accurate and properly supported.
06 — Advise on Energy-Saving Measures
Advise the Energy Consumer on energy-saving measures and monitor their implementation.
07 — Other Duties
Carry out other duties that may be determined by the Energy Commission.
These seven areas correspond to the REM functions set out under the EECA 2024 framework.
What Happens After Appointing a REM?
Appointing a Registered Energy Manager (REM) is only the beginning of an Energy Consumer's ongoing energy management process under EECA 2024.
Once the first REM is appointed, the organisation must develop and implement an Energy Management System (EnMS) within one year and begin its ongoing energy performance monitoring and EE&C reporting.
The first EE&C Report must be submitted within 30 days after the end of one year from the date of the first REM appointment, with subsequent reports submitted annually based on the REM appointment anniversary.
In simple terms, the process looks like this:
REM Appointment
↓
Energy Data Collection & Analysis
↓
EnMS Development & Implementation
↓
Energy Performance Monitoring
↓
Energy Efficiency Improvements
↓
EE&C Report Preparation & Submission
↓
Ongoing Annual Monitoring & Reporting
A REM is therefore not simply an appointment on paper. The role continues through the organisation's ongoing energy management, monitoring and reporting activities.
Need an External REM Type 2?
If your organisation requires an external Registered Energy Manager, we can support your energy management and EECA-related requirements as an External REM Type 2.
Our support may include:
External REM Type 2 services
Energy data collection and analysis
EnMS implementation support
Energy performance monitoring
EE&C Report preparation support
Energy-saving measure recommendations
Monitoring of energy efficiency initiatives
The scope of support may vary depending on your organisation's requirements.

Frequently Asked Questions About Registered Energy Managers (REM)
What is the energy consumption threshold for an Energy Consumer?
The prescribed energy consumption threshold is 21,600 GJ over the applicable 12-month period.
How long do I have to appoint a REM after receiving the notice?
The REM appointment must be made within three months from the date of the written notice issued by the Commission.
What is the difference between First Type and Second Type REM?
A First Type REM may be appointed by Energy Consumers with annual energy consumption between 21,600 GJ and 50,000 GJ. A Second Type REM is required for Energy Consumers exceeding 50,000 GJ under Regulation 5, while ST's current information states that a Second Type REM may be appointed by Energy Consumers exceeding 21,600 GJ.
Can I appoint an external REM?
Yes. Regulation 6 allows an Energy Consumer to appoint a qualifying REM who is not its employee or the employee of its related corporation, subject to the applicable requirements.
How long can an external REM be appointed?
An external REM appointed under Regulation 6 may be appointed for a period not exceeding three years from the date of the Commission's written notice.
What happens after the external REM appointment period ends?
Immediately after the expiry of the appointment under Regulation 6, the Energy Consumer is required to appoint a REM among its employees in accordance with Regulation 4.
