# Top 100 energy companies in Asia

Tamtam tracks 1,312 energy companies headquartered in Asia. This list ranks the 100 largest by number of employees on LinkedIn, led by Tata Group, SUMITOMO ELECTRIC INTERCON'T PROD (M) SB and Mahindra Group. Their median headcount is 8,678. Half of them were founded in 1973 or later. The most common headquarters are Mumbai (21), New Delhi (9) and Jakarta (7).

These are large Asian energy companies, many of which are headquartered in India. Most are diversified conglomerates, often founded in the late 19th or mid-20th century. For example, Tata Group, founded in 1868, is a global enterprise focused on improving community quality of life; Mahindra Group, founded in 1945, operates in farm equipment, vehicles, and IT; and Reliance Industries Limited spans hydrocarbon exploration, refining, and retail.

A significant pattern is the prevalence of Mumbai as a headquarters city, hosting major players like Larsen & Toubro, which specializes in engineering and construction, and Aditya Birla Group, a global conglomerate. Other prominent companies include SUMITOMO ELECTRIC INTERCON'T PROD (M) SB from Osaka, diversified into automotive and infocommunications, and PT Pertamina (Persero) from Jakarta, engaged in integrated energy sectors.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 13, 2026.
