These companies in Noida operate primarily in the energy sector, including oil and gas, renewables, and industrial machinery manufacturing. Most are mid-sized to large firms, with a few established before 2000, such as Isgec Heavy Engineering Ltd. (founded 1933) and Oil India Limited (founded 1959).
Key players include HPCL-Mittal Energy Limited, operating an integrated refinery-petrochemical complex, and JAKSON Group, focused on sustainable energy solutions like solar and biofuels. Inox Wind Ltd. manufactures wind energy solutions, while Bajaj Energy provides electricity in Uttar Pradesh. A notable pattern is the strong presence of companies involved in both traditional and renewable energy, reflecting a mixed energy landscape.

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 11, 2026.
