Kuala Lumpur is home to a concentration of energy companies, primarily focused on oil and gas. These range from large established groups like PETRONAS, a global energy company involved in hydrocarbon exploration and cleaner energy, and Tenaga Nasional Berhad, a leading utility company for electricity, to mid-sized firms such as Sapura Energy Berhad, which provides comprehensive oil and gas services.
The sector also includes diversified players like Genting Berhad, involved in power generation, and MISC Group, a global leader in energy-related maritime solutions. A notable pattern is the strong presence of companies engaged in various aspects of the oil and gas value chain, from exploration and production by PETRONAS Carigali Sdn. Bhd. to specialized services by Malaysia Marine & Heavy Engineering. Many of these companies were founded in the 1970s and 1980s.

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.
