TNB Remaco

What TNB Remaco does

TNB REMACO (TNB Repair And Maintenance Sdn. Bhd.) is a Malaysian specialist in operation and maintenance (O&M), overhaul, and repair and maintenance (R&M) services for power generation assets. Established in 1995 as a wholly-owned subsidiary of TNB Power Generation (TNB Genco) — itself part of Tenaga Nasional Berhad, Malaysia's largest electricity utility — the company serves operators of gas, steam, and hydro turbines, boilers, and generators across the full asset lifecycle. Its core service portfolio is organised around four pillars: Maintenance and Repair Services (mechanical, electrical, and control & instrumentation field services plus a dedicated Repair Centre); Test and Diagnostic Services; Project and Technical Services (EPC, project management and consultancy, commissioning); and Operation and Maintenance Management. The customer base comprises sovereign power utilities, government-linked companies, and independent power producers in Malaysia, Kuwait, Pakistan, Saudi Arabia, and adjacent markets.

The company's technical platform is anchored by a state-of-the-art Repair Centre in Klang equipped with reverse engineering, 3D dimensional scanning, finite element analysis, vacuum heat treatment, thermal coating (HVOF/Plasma), and large-scale on-site machining tools including 100-ton low-speed balancing machines and equipment purpose-built for Siemens V94.2 and GE LM2500 turbines. It holds ISO 9001, ISO 14001, ISO 45001, and ISO 27001 multi-site certifications. Operational credentials include running the world's first commercial GE 9HA.02 H-class gas turbines at the Sultan Ibrahim Power Plant (POWER Magazine Plant of the Year 2021, zero lost-time injuries over 10 million man-hours) and integrating third-party automation systems such as Valmet DNA for hydropower plant digitalisation.

TNB REMACO monetises through three primary revenue streams: long-term O&M contracts of typically 5–25 years (e.g., RM705 million Sabiya, RM763 million Balloki); project-based EPC/PMC engagements; and per-engagement MRO services. Pricing is not publicly disclosed; contracts are secured via competitive government and enterprise tenders. Go-to-market relies on direct enterprise field sales, government tendering, and joint ventures with local partners — most notably Al-Dhow Engineering in Kuwait, which anchors 11 active projects worth over RM4.54 billion and provides the template for GCC-wide expansion under the May 2025 ASEAN-GCC Summit MoU.
