Does the Pune rubber cluster profile print light diesel oil and diesel in kilograms an hour or kilograms a year?

The Energy and Resources Institute (TERI) profile of Pune's rubber cluster gives 536 tonnes of light diesel oil (LDO) and 75 tonnes of high speed diesel (HSD) for the cluster. Its unit table headings, "LDO consumption, kg/hr" and "HSD consumption kg/hr", only add up to those totals if they are kilograms a year.

What the profile prints (2017-18)

• Unit table, per typical unit: micro (25 units) 0.084 million kilowatt-hours (kWh), LDO 0, HSD 172. Small (45 units) 0.36 million kWh, LDO 4,464, HSD 430. Medium (10 units) 2.4 million kWh, LDO 33,480, HSD 5,160. The column headings read "LDO consumption, kg/hr" and "HSD consumption kg/hr".
• Cluster table: electricity 42.3 million kWh, LDO 536 tonne, HSD 75 tonne, 4,226 tonnes of oil equivalent (toe) in all.

The check

• Electricity ties: 25 x 0.084 + 45 x 0.36 + 10 x 2.4 = 2.1 + 16.2 + 24.0 = 42.3 million kWh.
• LDO ties only per year: 45 x 4,464 + 10 x 33,480 = 200,880 + 334,800 = 535,680 kg, which is the printed 536 tonnes.
• HSD ties only per year: 25 x 172 + 45 x 430 + 10 x 5,160 = 4,300 + 19,350 + 51,600 = 75,250 kg, the printed 75 tonnes.
• Per hour cannot be right: 33,480 kg an hour for 8,760 hours is 293,285 tonnes, against 244 toe for the whole medium unit. Our reading is that the headings should say kg a year. The profile does not say.

Smaller things that do not quite tie

• The share chart prints electricity 87 percent, LDO 11 and HSD 2. The toe table gives 3,638, 523 and 65 of 4,226, which is 86.1, 12.4 and 1.5 percent. The chart and the table do not match: 87 against 86.1 for electricity, 11 against 12.4 for LDO. The chart's basis is not stated.
• The size chart prints micro 5 percent, small 36 and medium 59. The unit rows times unit counts give 175, 1,620 and 2,440 toe, 4,235 in all, which is 4.1, 38.3 and 57.6 percent. Micro 5 against 4.1, small 36 against 38.3 and medium 59 against 57.6 are not rounding. Only the 4,235 against a printed 4,226, a gap of 0.2 percent, looks like rounding.
• Diesel is printed as 75 tonnes and 65 toe, 0.87 toe a tonne, while LDO is 536 tonnes and 523 toe, 0.98. Two light oils should sit close, and we cannot say which line is off. At 0.98 the diesel would be about 73 toe, 8 more, which moves the total by 0.2 percent.

What to use

Quote annual figures, in kWh, litres or tonnes, and say they are per year. Do not use the chart percentages: use the table. The Pune parts-makers page here quotes the chart's 87 percent for electricity; the table gives 86.1.

Medium unit, read as kg a year (our calculation)

• LDO: 33,480 kg a year, about 33.5 tonnes, or 92 kg a day over 365 days
• HSD: 5,160 kg a year, about 5.2 tonnes, or 4.5 to 5.0 toe, depending on which of the profile's two diesel ratios you use (0.867 toe a tonne from 65 and 75, or 0.976 from 523 and 536)
• Electricity: 2.4 million kWh, about 206 toe at the profile's own conversion (3,638 toe for 42.3 million kWh)
• Total: 206.4 + 32.7 + 4.5 to 5.0 = 243.6 to 244.1 toe, the printed unit total of 244 either way

The toe line uses the cluster table's own ratio of toe to kWh and LDO. The printed 244 matches only if the fuel columns are per year.

What Senseible does here

Senseible reads fuel invoices and electricity bills into dated, fingerprinted records, so your kilowatt-hours and litres are on file by date. Your own annual kWh and litres are then on file, which is firmer than the profile's unit table.
