Karnal's chemical profile gives a typical other-chemicals unit as 114.92 tonnes of oil equivalent (toe) a year, yet a heat range of 132 to 474 toe: which is my benchmark if I run a coal boiler?

Use the range of 132 to 474 toe. The 114.92 toe average counts every unit, and the profile says heat energy is used in only one third of other-chemicals units. If it is exactly one third, a unit that burns fuel for heat averages about 303 toe of it (our reading).

What the Karnal table prints

• Pharmaceutical and active pharmaceutical ingredient units: electricity only, 6.82 toe a year, in a printed range of 4.4 to 8.4.
• Other chemicals, printed range: electricity 0.7 to 44.5 toe, thermal energy 132 to 474 toe.
• Other chemicals, typical row: thermal 101.15, electricity 13.77, total 114.92 toe. Thermal is 88% of it (101.15 / 114.92).
• So the typical thermal figure of 101.15 sits below the bottom of its own range, 132.

The profile's own explanation

TERI writes that the average thermal energy and the total energy of other-chemicals units are below the lower limit "as thermal energy is being used in one third number of such units". So the typical row is an average over all the units, including those that burn no fuel for heat.

Our reading, not printed in the profile: if exactly one third use heat, those units average 101.15 x 3 = 303.45 toe of heat, inside the printed 132 to 474. The profile gives no exact count of units with a boiler.

Your range in tonnes of coal

Table 5.2.2 implies 0.4514 toe a tonne: it prints 7,007 tonnes of coal and 3,163 toe. If all your heat came from coal, 132 toe is about 292 tonnes a year, 303 toe about 672 and 474 toe about 1,050. At 1.76 kg of carbon dioxide (CO2) per kg of Indian coal that is about 515, 1,183 and 1,848 tonnes of CO2 (estimate). The profile's own CO2 for coal is 12,724 tonnes, about 1.82 tonnes per tonne of coal, against the 1.76 used here. A unit that also burns LDO or wood uses less coal for the same heat.

The cluster totals use two different splits

• The text says heat is 82% of the cluster's 4,947 toe and electricity 18%. The lines of Table 5.2.2 give heat as coal 3,163 plus oil 1,033 = 4,196 toe, which is 84.8%, and electricity 751 toe, which is 15.2%. The profile's own pie shows electricity at 15%.
• The lines add up: 3,163 + 1,033 + 751 = 4,947 toe, and 12,724 + 3,209 + 6,899 = 22,832 tonnes of CO2, as printed. We could not find why the text says 82 and 18, so use the lines.

Example: a Karnal paint unit with a coal boiler

• Coal bought and burnt: 400 tonnes a year (example figure)
• Heat: 400 x 0.4514 = 180.6 toe, inside the printed 132 to 474
• Against the 101.15 average it looks 79% high (180.6 / 101.15 = 1.79). Against the boiler range it is ordinary.
• CO2: 400 x 1.76 = 704 tonnes

The 400 tonnes is an example. The 0.4514 toe a tonne is the conversion implied by TERI's table, about 4,514 kilocalories a kg (our arithmetic).

What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so your coal tonnes and units of power sit in one place to set against the right band. Which band you belong to depends on whether you burn fuel for heat, which your invoices show.

• Your MSME carbon number
• Karnal chemical units: coal, oil and power
• Coal invoice: what to read
• Benchmark plant energy against the sector
