Who We Are

Malaysia's most experienced District Cooling Systems owner and operator — powering a sustainable energy future since 1993.

Providing District Cooling Systems Since 1993

TNB Engineering Corporation Sdn Bhd (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 experience 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 two 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.

TNEC also has vast experience in EPC of Large Scale Solar Photovoltaic Plant (LSSPV) with projects capacities amounting to 109MWac in the domestic environment. This is part of TNEC's aspiration to pursue an active role in supporting Malaysia's renewable energy generation target by leveraging on its competitiveness and strength, in the country and the region.
