TNB Engineering Corporation (TNEC) was established in October 1993 as a wholly-owned subsidiary of Tenaga Nasional Berhad (TNB). Today, we are the most experienced District Cooling Systems (DCS) owner and operator in Malaysia. We started as an engineering specialist providing energy technical services for TNB, and our experiences and expertise were further expanded in the construction of power stations and DCS  locally, in Asia and the Middle East.


Having extensive DCS experience spanning more than 2 decades, TNEC provides the full range of services for DCS projects, from the initial concept or business viability study to the investment, engineering, procurement, and construction (EPC) contract, project financing, ownership as well as comprehensive operations & maintenance.
