# Why does the Coimbatore bakery profile show electricity as 83, 310 and 206 kilowatt hours a year per unit?

Canonical: https://senseible.earth/answers/coimbatore-bakery-unit-energy-table-decoded

Those figures cannot be per unit kilowatt hours. In the profile by The Energy and Resources Institute (TERI), 83 + 310 + 206 = 599, which matches the cluster's electricity in tonnes of oil equivalent (toe), so the table looks like cluster toe (our reading). Its 33 and 15 toe a bakery imply about 360 bakeries, not 700 (our arithmetic).

## The table as printed

- Headed Energy consumption of bakery units in Coimbatore cluster, with columns thermal energy (toe a year), electricity (kilowatt hours (kWh) a year) and total energy (toe a year a unit).
- Medium: 582, 83, 33. Small: 1,917, 310, 15. Micro: 2,700, 206, 15.

## Why they look like cluster toe

- The profile's cluster table gives electricity 599 toe, diesel 1,083, liquefied petroleum gas (LPG) 1,416 and wood 2,700, a total of 5,798 toe.
- The electricity column adds to 83 + 310 + 206 = 599. The thermal column adds to 582 + 1,917 + 2,700 = 5,199, which is 1,083 + 1,416 + 2,700.
- By size: medium 582 + 83 = 665 toe (11.5%), small 1,917 + 310 = 2,227 (38.4%), micro 2,700 + 206 = 2,906 (50.1%). The profile's energy pie says 12%, 38% and 50%. The three add to 5,798.
- 599 toe is about 6.97 million kWh at about 11,630 kWh a toe, which is the cluster's 7.0 million kWh. No single bakery uses 83 kWh a year.

## How many bakeries does 5,798 toe cover?

- Divide each size's toe by the profile's toe a unit: 665 / 33 = 20 medium, 2,227 / 15 = 148 small, 2,906 / 15 = 194 micro. That is 362 bakeries.
- The shares of medium, small and micro come to 5.6%, 41% and 53.5%, against the profile's pie of units by size, 5%, 41% and 54%. The profile also counts about 370 bakeries in the city area.
- The profile says more than 700 bakeries in the district. Our reading: the energy table and its unit figures fit about 360 bakeries, probably the city units. Spread over 700, the same 5,798 toe would average 8.3 toe a bakery, well under the 15 toe it gives for a micro or small one.
- Another page on this site divides the cluster fuel totals by 700 to get an average bakery. If the table covers about 360, the average is about twice as large, 16 toe a bakery. Neither average is your bakery.

## What to use instead

Your own invoices: LPG in kilograms, oven diesel in litres, wood in tonnes and kWh from the monthly power bill. A buyer or a lender will ask for them before a cluster average.

## Cluster toe, units implied and an average bakery (estimate)

- Cluster toe: 599 + 1,083 + 1,416 + 2,700 = 5,798
- Units implied: 665 / 33 = 20; 2,227 / 15 = 148; 2,906 / 15 = 194; total 362
- Average at 362 bakeries: 5,798 / 362 = 16.0 toe. At 700: 8.3 toe
- Electricity at 362: 7.0 million kWh / 362 = 19,337 kWh a bakery. At 700: 10,000 kWh
- Fossil carbon dioxide (CO2) at 362, on the financial year 2025-26 grid factor and diesel at 2.645 kg a litre: 19,337 x 0.675 = 13.1 tonnes; 3,149 litres x 2.645 = 8.3 tonnes; 3,315 kg of LPG x 2.98 = 9.9 tonnes; about 31 tonnes

The 15 and 33 toe a unit are rounded in the profile, so the unit counts are approximate. The profile's cluster quantities are 7.0 million kWh, 1,140 kilolitres of diesel and 1,200 tonnes of LPG. The diesel factor of 2.645 uses the Central Electricity Authority's density of 0.83 kg a litre.

## What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so your LPG, diesel and electricity are on file by month, ready to set beside any cluster average. It does not know how many bakeries a profile covers.
