Texmaco Rail & Engineering Ltd has successfully completed the erection and commissioning of Hydro-Mechanical (HM) systems for the prestigious 2,000 MW (8 × 250 MW) Subansiri Lower Hydroelectric Project, located at the Arunachal Pradesh–Assam border. The achievement marks a key milestone in the commissioning of one of India’s largest renewable energy projects and reinforces Texmaco’s position in large-scale infrastructure development.
Critical Role as Sole Hydro-Mechanical Contractor
As the sole HM contractor, Texmaco was entrusted with the complete lifecycle of the hydro-mechanical scope, including design, manufacture, supply, erection, testing, and commissioning of the HM systems. These systems are critical to the safe and efficient operation of the generating units and play a central role in ensuring the project’s timely execution.
Texmaco’s successful delivery highlights its capabilities in executing complex hydro-mechanical engineering works for large hydropower projects.
NHPC Advances Unit Commissioning
NHPC, the developer and owner of the Subansiri Lower Hydroelectric Project, has already declared the Commercial Operation Date (COD) for the first generating unit, with three additional units commissioned. The remaining four units are scheduled for phased commissioning through FY 2026–27, according to the project timeline.
Boost to Clean Energy and National Grid
With an installed capacity of 2,000 MW, the Subansiri Lower project is among the largest renewable energy projects in India. Once fully operational, it will supply substantial electricity to the national grid, significantly reducing dependence on fossil fuels and supporting India’s clean energy and decarbonisation goals.
Strengthening Texmaco’s Infrastructure Portfolio
Texmaco’s involvement in this landmark hydropower project underscores its leadership in hydro-mechanical engineering and its ability to deliver high-impact infrastructure solutions. The achievement adds to the company’s expanding portfolio across energy and infrastructure sectors, further strengthening its role in India’s renewable energy transition.
