How many Mohali, Panchkula and Chandigarh light engineering units supply OEMs?

The Energy and Resources Institute (TERI) counts around 6,000 Micro, Small and Medium Enterprise (MSME) units in the Mohali-Panchkula-Chandigarh cluster, around 2,600 of them light engineering and about 1,500 vendors to original equipment manufacturers (OEMs). Vendor turnover is put at over rupees (Rs) 2,000 crores.

The counts, as TERI prints them

• Around 6,000 MSME units, in a cluster spread over an area of around 15 square kilometres.
• Around 2,600 are light engineering industries: machining, sheet metal components including ancillary products for railways and tractor industries, fastener manufacturing and steel fabrication.
• About 1,500 of those are vendors that mainly cater to the demands of OEMs.
• The vendor units have an approximate annual turnover of over Rs 2,000 crores.
• OEMs the profile names: Punjab Tractors Limited (PTL, now Mahindra & Mahindra), Swaraj Mazda, Swaraj Combines, Hindustan Machine Tools (HMT), Sonalika, Eicher Tractors, automobile and agricultural components makers, and the Rail Coach Factory (Kapurthala) of Indian Railways.
• Four industry associations are active: Mohali Industries Association, Industries Association of Chandigarh, Chamber of Chandigarh Industries, and Haryana Chamber of Commerce & Industry, Panchkula.

What the counts say about who gets asked

This is my reading, not TERI's. About 1,500 of 2,600 is 58%, so more than half of the light engineering units sell to an OEM, and 2,600 of 6,000 is 43% of all units. An OEM's supplier questionnaire therefore lands on a plant that has many near copies within a few kilometres, on the same grid and often buying the same steel.

Rs 2,000 crores over 1,500 vendors averages Rs 1.33 crore a vendor. The profile says 'over', so that is a floor for the average, and one unit's turnover can sit far from it.

What each of those plants has to send

• Electricity is the main energy for almost all the parts makers: kilowatt-hours (kWh) from the monthly bills.
• High speed diesel for diesel generator sets, from fuel invoices. The profile says most machining units are in Mohali and Panchkula, which face severe power shortages, so units have 'no option but to invest in alternate power sources like diesel generator (DG) sets'.
• Its table of energy inputs lists only electricity and high speed diesel, so my reading is that a parts maker's Scope 1 is mostly its generator diesel.

What the profile does not say

It prints no year for its counts. The 48 energy audits it reports were on units the industry associations picked, so they are a sample, not a head count. It does not say how many vendors have been sent a carbon request.

Scope: this is the wider Mohali-Panchkula-Chandigarh light engineering profile, which prints no year. The live Mohali page uses TERI's 2015 Mohali engineering profile, which counts about 4,000 MSMEs and 900 of them engineering, so the two sets of counts differ because the profiles cover different areas and years, not because one is wrong.

The share arithmetic (my calculation from printed counts)

• Vendors among light engineering units: 1,500 / 2,600 = 58%
• Light engineering among all units: 2,600 / 6,000 = 43%
• Average vendor turnover: Rs 2,000 crore / 1,500 = Rs 1.33 crore (a floor, because the profile says over)

Counts and turnover are the profile's own, undated. They are rounded estimates.

What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so a vendor can send an OEM its Scope 1 and 2 for twelve months, each line traced to a bill. It is not a third-party verifier and does not issue credits.

• Mohali tractor parts cluster carbon
• Where a machining unit's power goes
• Mohali profile diesel: litres or kilolitres
• Green loan readiness check
