How much electricity does light-emitting diode (LED) lighting save in a seafood processing plant?

Lighting is about 1 to 3% of a seafood plant's electricity, and the profiles say LED lamps cut lighting bills by up to 55%, payback about 2 years. That is at most 0.55 to 1.65% of the plant total. The extra gain is less heat for the refrigeration to remove.

The figures in the profiles

• Lighting share of a typical plant's electricity: about 1 to 3% in the text. The Veraval chart shows 2.0% and the Bhubaneswar chart 2%.
• LED saving on the lighting bill: up to 55%, simple payback about 2 years.
• LED lamps are claimed to keep at least 80% of their original light output over about 50,000 hours.
• Inefficient lamps add heat load to the refrigeration system; LEDs give the same lux with much less heat.

What it is worth in the plant total

Multiply the lighting share by 55%. At 1% of electricity the saving is 0.55% of the plant total, at 2% it is 1.1%, at 3% it is 1.65%. Compare that with up to 5 to 8% from replacing refrigerant pipe, insulation and valves in the same profiles. Lighting is worth doing for the 2 year payback and the cooler rooms, but it will not move a footprint much.

What the profiles do not give

They give no figure for the refrigeration saving from the lower heat, so do not add one. The 55% is "up to", not typical.

The 3,000 tonne a year Veraval plant, financial year (FY) 2025-26 grid factor (example)

• Plant electricity in the profile: 3,168,760 kilowatt hours (kWh)
• Lighting at 1%: 31,688 kWh; saving 55% = 17,428 kWh = about 11.8 tonnes of carbon dioxide (CO2) a year
• Lighting at 2%: 63,375 kWh; saving 34,856 kWh = about 23.5 tonnes
• Lighting at 3%: 95,063 kWh; saving 52,285 kWh = about 35.3 tonnes
• Share of plant total saved: 0.55%, 1.1% and 1.65%

The saving uses the profile's upper figure of 55%. Your lamps and hours decide the real value. 0.675 kg CO2 per kWh is the FY 2025-26 grid factor.

What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so a plant can compare the months before and after a lighting change. It does not count fittings or lamp hours.
