Why do Bhubaneswar shrimp plants use about half as much electricity again per tonne as Veraval fish plants?

Dividing the profiles' cluster totals gives about 981 kilowatt hours (kWh) a tonne at Veraval and 1,491 at Bhubaneswar, a ratio of 1.5. The quoted averages are 1,100 and 1,520. Neither profile explains the gap; product, season and utilisation all differ.

Three readings of each cluster

• Veraval cluster total: 106 million kWh over about 108,000 tonnes, 981 kWh a tonne. Its three plant rows: 929, 948 and 1,056. Its quoted average: about 1,100.
• Bhubaneswar cluster total: 50.1 million kWh over about 33,600 tonnes, 1,491 kWh a tonne. Its three plant rows: 1,583, 1,528 and 1,444. Its quoted average: about 1,520.
• Bhubaneswar's three readings sit within about 6% of the cluster total. Veraval's quoted 1,100 is above its cluster total and above all three plant rows. The profile does not say why; use the plant rows or the cluster total, not the quoted average, if you need a figure that ties to its own tables.

What differs between the clusters

• Product: Bhubaneswar is over 90% shrimp. Headless block shrimp recovers about 65 to 70% of raw weight and peeled individually quick frozen (IQF) shrimp about 55%. Veraval processes ribbon fish, croaker, cuttlefish, squid, shrimp and lobster.
• Utilisation: Bhubaneswar plants average 40 to 60% of capacity and run as low as 20% outside the peak. Veraval plants run at 100% in peak season and as low as 50% for the rest of the year.
• Basis: Bhubaneswar quotes kWh per tonne of production on an assumed 90% shrimp mix. Veraval quotes per tonne of processing. Neither says whether the tonne is raw intake or packed product.

Our reading, not the profiles'

Product mix, peeling yield and slack months probably explain part of the gap, since cold stores and ice plants run whatever the output. The profiles do not measure how much. Do not tell a buyer your plant is "efficient" or "inefficient" against either cluster until you know which tonne each one divided by.

What to use for your own plant

Use your own monthly kWh from bills and tonnes from your packing list, and say which tonne you used. The cluster figures are only a range to sense-check against.

Electricity only, financial year (FY) 2025-26 grid factor (example)

• Veraval: 106,000,000 / 108,000 = 981 kWh a tonne; x 0.675 kg = about 662 kg of carbon dioxide (CO2) a tonne
• Bhubaneswar: 50,100,000 / 33,600 = 1,491 kWh a tonne; x 0.675 kg = about 1,006 kg a tonne
• Ratio of the two cluster figures: 1,491 / 981 = 1.52. Ratio of the quoted averages: 1,520 / 1,100 = 1.38

Diesel is not included in these lines. Tonnes and kWh are from the profiles (Veraval 2016-17, Bhubaneswar 2015-16).

What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so a plant can see its own kilowatt hours month by month, ready to divide by your packed tonnes. Senseible does not hold your production log, so divide by the tonnes in your own packing list.

• Seafood kWh per tonne and flake ice
