20 Energy Saving Tips for Industry

20 Practical Energy Savings Tips for Industry

Reducing energy use does more than help the environment — it is among the most effective ways for a plant to lower running costs, because power typically accounts for a big slice of operating expenditure. Detailed fine-tuning may call for a professional energy auditor, yet many quick wins can be found just by studying your own systems. Here are 20 common energy-saving measures worth trying before you book a full energy audit.

Measure and Understand Your Loads

• Measure — pinpoint your problem areas: As the saying goes, if you cannot measure it, you cannot control it. Fit individual energy meters at each load centre (power distribution panel) if they are not already in place, then identify which equipment draws the most energy so you know where to concentrate your effort.
• Improve motor performance: Adding a variable drive is a popular energy-saving project, but even the best drives operate at roughly 98% efficiency, so about 2% is lost. Apply drives wisely; where speed stays constant, right-size the motor itself instead.
• Prefer soft starters over DOL: On motors above 7.5 HP, swap direct-on-line starters for soft starters.
• Study your compressor: A compressor driven by a motor above 50 HP puts a heavy load on the system. Look at its load/unload pattern to understand how it behaves — power drawn during no-load periods is pure energy loss. Think about a drive if the compressor is loaded for under 85% of its running time (loading hours ÷ running hours × 100).

Optimise Compressed Air and Power Quality

• Compressed air: Running at the lowest air pressure your process needs is the best way to save. Choose energy-efficient nozzles. Typically 10–15% of air is lost through leaks and poor system design, so fix leaks and improve the distribution layout. Aluminium extruded piping reduces pressure drop and raises system efficiency.
• Read your energy bill: You are charged for both power consumption and power demand, and a better power factor can optimise both. The best approach is a centralised APFC capacitor panel, backed by small capacitor panels close to the loads. Some distribution utilities penalise consumers for a low power factor.
• Go solar: Sunshine costs nothing, and India receives plenty of it. Think about rooftop solar panels — grid-connected or off-grid — to generate your own electricity.
• Consider CNG: If LPG is your current fuel, consider switching to CNG.

Smart Operation of Equipment and Facilities

• Switch equipment on and off wisely: Plenty of idle machines keep drawing power, and many heating loads use a lot of energy at start-up.
• Use natural light: Refine building design so more daylight reaches shop floors and offices.
• Set comfort air conditioning sensibly: Compressors work to bring room temperature down; the most optimised setting is 27°C, which can deliver substantial savings.
• Check insulation: Inspect the heat insulation on refrigerant gas lines, AHU ducts and rooms. A thermal camera helps you judge insulation condition — to pick one, read Basic Thermal Camera from Flir – C5.
• Reduce clean room heights: Air conditioning cools the whole room volume, so optimising clean room height cuts the AC workload and energy use.
• Shade your windows: Add sheds or shading to windows to block heat transfer from the sun and the outdoor environment.
• Use LED wisely: LEDs save well where lights stay on for long stretches, but not where they are switched on and off frequently.
• Clean AC outdoor units: The heat removed by the AC has to be dissipated in evaporative cooling units with cooling fins. Dust and dirt build-up traps heat and restricts cooling, forcing the AC to use more energy.
• Be collaborative and sensitive: Help build a workforce that is energy-aware — it will help you save energy.
• Insulate furnaces: Use thermal imaging to spot and repair insulation breaks and heat loss.
• Recover waste heat: Capture waste heat from furnace exhaust and compressor radiators to preheat other processes.
• Cool water to the right temperature: Never cool more than you need — optimise process temperatures carefully to reduce the delta T, which lowers energy consumption.
