These energy companies in Uttar Pradesh primarily operate in the oil and gas, industrial machinery manufacturing, and renewables sectors. The list includes a mix of large established enterprises and mid-sized firms. Notable companies include Uttar Pradesh Power Corporation (Uppcl), responsible for electricity transmission and distribution; Isgec Heavy Engineering Ltd., a diversified heavy engineering company; HPCL-Mittal Energy Limited, operating an integrated refinery-petrochemical complex; and JAKSON Group, focused on sustainable energy solutions like solar and biofuels.

## 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 12, 2026.
