# Does the Gokak jaggery energy table use a bagasse heating value above the 3,000 to 4,000 kilocalories the profile gives?

Canonical: https://senseible.earth/answers/gokak-jaggery-bagasse-toe-heating-value-check

Probably, by about 10%. The profile by The Energy and Resources Institute (TERI) gives dried bagasse as 3,000 to 4,000 kilocalories (kcal) a kilogram. Its table's 34,735 tonnes of oil equivalent (toe) over 78,200 tonnes of bagasse works out near 4,400 kcal a kilogram (our division). The profile prints no heating value for its toe.

## What the profile prints

- Dried bagasse: 3,000 to 4,000 kcal a kilogram.
- Cluster: electricity 3.13 million kilowatt hours (kWh), bagasse 78.2 thousand tonnes, diesel 66.3 kilolitres, energy 34,735 toe, carbon dioxide (CO2) 2,742 tonnes, energy bill rupees (Rs) 29.4 million. Micro units 19,420 toe, small units 15,315.
- Per unit: micro 18,461 kWh, 460 tonnes of bagasse, 500 litres of diesel and 204 toe. Small 55,384 kWh, 1,380 tonnes, 750 litres, 613 toe.

## Toe in each tonne of bagasse

- Electricity: 3.13 million kWh is about 269 toe, at about 11,630 kWh a toe. Diesel: 66.3 kilolitres is about 63 toe at 0.95 toe a kilolitre, a ratio we derived from the Coimbatore profile (1,083 toe over 1,140 kilolitres); it moves the answer by under 0.2%.
- Left for bagasse: 34,735 minus 269 minus 63 = 34,403 toe over 78,200 tonnes is 0.44 toe a tonne, which at 10 million kcal a toe is 4,400 kcal a kilogram.
- A micro unit gives the same: 204 minus 1.6 (18,461 kWh) minus 0.5 (500 litres) = 201.9 toe over 460 tonnes is 0.44.
- At 3,000 to 4,000 kcal, 78,200 tonnes is 23,460 to 31,280 toe. The table's bagasse share is about 10% above the top of that range (34,403 / 31,280 = 1.10).

## What ties

- Bill: 3.13 million kWh x Rs 8 = Rs 25.04 million, plus 66.3 kilolitres x Rs 65 = Rs 4.31 million. Total Rs 29.35 million, printed 29.4.
- The carbon dioxide column, with bagasse's carbon dioxide left out, is worked through on the live Gokak energy and carbon page linked below, so it is not repeated here.

## Why it matters to a jaggery unit

- Bagasse CO2 goes on its own biogenic line. At the table's implied 34,403 toe: 34,403 x 41.868 gigajoules (GJ) x 100 kg a GJ = about 144,000 tonnes. A lower heating value gives a smaller figure, so the heating value matters before you quote it.
- Heating value swings with moisture. The profile says the crusher's bagasse passes through a continuous type dryer, and micro units usually dry it in the sun. Weigh your bagasse, and ask a lab for its heating value before you quote a figure per tonne of jaggery.

## Heating value implied by the table

- Electricity: 3,130,000 kWh / 11,630 = 269 toe. Diesel: 66.3 x 0.95 = 63 toe
- Bagasse: 34,735 minus 269 minus 63 = 34,403 toe. Per tonne: 34,403 / 78,200 = 0.44 toe = 4,400 kcal a kg
- Range check: 78,200 tonnes x 3,000 to 4,000 kcal = 23,460 to 31,280 toe
- Biogenic CO2 at 100 kg a GJ (the Intergovernmental Panel on Climate Change default for other primary solid biomass): 34,403 x 41.868 x 100 = 144,039,000 kg, about 144,000 tonnes

Quantities are the profile's, for 2017-18. One toe is 10 million kcal, or 41.868 gigajoules.

## What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so your diesel and electricity are on file by month. It does not weigh bagasse or know its heating value; that needs your own weighbridge slips and a lab test.

Last reviewed 2026-11-06. Figures are the profile's own, for 2017-18. The 4,400 kcal is our division of its printed toe and tonnes, and the diesel toe uses a 0.95 ratio we derived from the Coimbatore profile. The profile gives no heating value for its toe, so the answer is our reading.
