Permen ESDM 8/2025: Factory Energy Management Guide
Permen ESDM 8/2025: Factory Energy Management Guide
Energy management is no longer just a utility-cost initiative for large Indonesian industrial users. Permen ESDM No. 8/2025 creates a structured obligation covering competent energy management, efficiency programs, periodic audits, implementation and reporting.
Industrial users above the threshold must implement energy management
Permen ESDM No. 8 Tahun 2025 has been in force since 13 March 2025 and replaces the previous energy-management regulation.
For the industrial sector, users of energy and/or energy sources consuming at least 4,000 tonnes of oil equivalent (TOE) per year are required to implement energy management.
The regulation identifies four core obligations: appointing an Energy Manager, preparing an Energy Efficiency program, conducting periodic Energy Audits and implementing recommendations from those audits.
The requirement is important for maintenance and procurement teams because energy management is not limited to producing a report. The regulation expressly includes operational control, consideration of energy performance in new or modified equipment and processes, and consideration of energy performance in procurement.

What industrial facilities need to do
| Requirement | What it means in practice |
|---|---|
| Energy Manager | A competent Energy Manager coordinates implementation of the energy-management program. |
| Energy Efficiency Program | The program includes planned actions, energy type and consumption, efficient equipment, efficiency measures, production/service output and energy performance. |
| Periodic Energy Audit | The audit is carried out by an internal and/or external Energy Auditor holding the required competency certificate. |
| Audit frequency | At least once every three years, including at least one Significant Energy Use (SEU) item. |
| Audit recommendations | Recommendations are to be implemented within the timeframe required by the regulation, subject to its provisions. |
| Monitoring and evaluation | Measurement, recording, comparison, analysis and reporting form part of implementation. |
| Annual reporting | Energy-management implementation must be reported annually to the Minister, no later than 30 June of the following year. |
Do not start with “buy a VFD” or “replace all motors”
Energy-efficiency projects should start by identifying where energy is used, how operation varies and which equipment materially influences the site's energy performance.
A motor running continuously at its design load presents a different opportunity from a pump throttled heavily by a valve. A compressed-air system may have efficient compressors while still wasting energy through leaks and inappropriate pressure. A chiller may be efficient but poorly sequenced.
Measurement helps distinguish these problems before capital is committed.
Focus resources where energy performance can materially change
A Significant Energy Use is not automatically the largest motor in the plant. Identification should reflect the organization's methodology and energy data.
Compressed air
Often important because generation, distribution pressure and leakage interact across the whole plant.
Motors & pumps
Large operating hours and variable process demand can make drive systems significant energy users.
HVAC / chillers
Cooling systems can become major electrical loads in climate-controlled industrial facilities.
Boilers / ovens
Fuel consumption, combustion, insulation and heat recovery can influence thermal energy performance.
Process heating
Electric heaters, furnaces, dryers and related systems require process-specific evaluation.
Production equipment
High operating hours or energy intensity can justify closer monitoring of individual process assets.
Efficiency is about the system, not the motor nameplate alone
| Issue | Possible action | Verify first |
|---|---|---|
| Oversized motor | Review motor/load matching | Actual load profile and starting requirement |
| Throttled pump | Evaluate control method or VFD | System curve, required flow/head and operating range |
| Damaged bearings | Correct mechanical condition | Alignment, lubrication, vibration and load |
| Poor power quality | Investigate supply and load | Voltage imbalance, harmonics and electrical measurements |
| Frequent rewinding | Review root cause | Electrical, thermal, mechanical and environmental history |
| Idle running | Improve operating control | Production and process constraints |
Pressure, leakage and inappropriate use can waste compressor energy
Compressed air is convenient but energetically expensive because electrical energy is converted into compressed air and then distributed through a system with pressure loss and leakage.
A useful program can include leak surveys, operating-pressure review, filter pressure-drop monitoring, compressor sequencing, storage and evaluation of inappropriate compressed-air uses.
Ultrasonic leak detection can support surveys, but detected leaks still need tagging, repair ownership and verification.
Cooling efficiency depends on load, controls and heat transfer
Filters
Dirty filters can increase airflow resistance and affect system performance.
Coils
Fouling reduces heat-transfer performance and can increase system demand.
Pumps
Operating point, throttling, mechanical condition and control all matter.
Cooling towers
Water condition, fan control, fill and approach temperature affect performance where towers are used.
Chiller sequencing
Multiple chillers should be operated according to actual system load and design.
Setpoints
Overcooling or unnecessary pressure/temperature targets can create avoidable energy use.
Boilers, steam and insulation need system-level analysis
| Area | Possible energy issue |
|---|---|
| Combustion | Air/fuel control and combustion condition affect efficiency and emissions. |
| Insulation | Damaged or missing insulation increases heat loss and creates surface-temperature hazards. |
| Steam traps | Failed traps can lose steam or impair condensate removal. |
| Condensate | Recovery can retain heat and treated-water value where the process allows it. |
| Blowdown | Operating practice should balance water chemistry and energy loss. |
| Leaks | Steam and hot-water leaks waste both energy and treated water. |
Turn the audit into a pipeline of verified improvement
Establish the baseline
Collect reliable consumption, operating and production data.
Identify significant use
Focus detailed analysis where energy consumption or improvement opportunity is material.
Measure the system
Use appropriate instruments rather than assumptions based solely on rated equipment power.
Identify opportunities
Separate low-cost operational actions from maintenance and capital projects.
Quantify savings
State baseline, assumptions, operating hours and expected energy-performance change.
Implement
Assign ownership, budget, engineering review and target date.
Verify
Compare performance after implementation using appropriate measurement and normalization.
Lowest purchase price and lowest lifecycle energy cost are not always the same
Permen ESDM 8/2025 explicitly includes consideration of energy performance in procurement. That does not mean procurement must always buy the highest-efficiency product available regardless of application.
| Product | Energy-related information worth reviewing |
|---|---|
| Electric motor | Efficiency class, load, duty, speed, starting and compatibility with the driven equipment. |
| Pump | Required duty point, efficiency curve, operating range and control method. |
| Air compressor | Specific energy, pressure, control type, turndown and real demand profile. |
| Chiller | Full- and part-load efficiency, cooling requirement and local operating conditions. |
| VFD | Motor/load compatibility, control function, harmonics, environment and bypass strategy where applicable. |
| Measurement tool | Range, accuracy, logging, calibration and required electrical safety category. |
