L&T shares soar 2% on bagging ₹5,000-10,000 crore electricity grid orders in India and Middle East

This comes as its Power Transmission & Distribution (PT&D) vertical bagged a batch of “major” orders for establishing electricity grid system elements in India and the Middle East. According to L&T’s classification, major orders translate to projects ranging between ₹5,000 and ₹10,000 crore.

At around 10:53 am, the stock was trading 1.79% higher at ₹4,335.60 per equity share.

Order wins

In a regulatory filing, the construction major said that, in India, PT&D has received an order for the design, supply, and construction of two 220 kV gas-insulated substations in the Durgapur–Raniganj–Asansol industrial belt of West Bengal.

The scope also includes associated transmission line segments with advanced conductors and multi-circuit towers, it stated, adding that, “These grid modernisation jobs will provide a stable voltage profile and enhance reliability of power networks for infrastructure and industrial projects in the region.”

In the Middle East, PT&D has won orders up to 500 kV level in three different countries in the region. The projects, from key utilities for the turnkey construction of five substations and over 250 km transmission lines, also involve supplying and installing a 400 kV underground cable system.

In a separate regulatory filing on February 24, the company stated that two of its business verticals, Heavy Civil Infrastructure (HCI) and Heavy Engineering (HE), jointly won a “significant” order from the Department of Atomic Energy of the Government of India, for establishing the LIGO India Observatory at Aundha in Maharashtra’s Hingoli district.

A significant order translates to a project ranging from ₹1,000 crore to ₹2,500 crore.

The scope of the project comprises comprehensive engineering, procurement and construction of vibration-sensitive specialised high-precision civil infrastructure, along with manufacturing and installation of an ultra-high vacuum compatible 8 km beam tube and critical equipment for vacuum infrastructure.

L&T’s scope also extends to integrating mechanical, electrical, HVAC, fire protection, vacuum control, monitoring system and all support utilities.

The project has a completion deadline of 48 months.

The LIGO India Observatory, the company added, will be one of India’s flagship ‘Mega Science’ projects, developed through a collaboration between Indian research institutions, RRCAT and IPR, and the LIGO Laboratory of the United States, with support from Caltech and MIT.

LIGO (Laser Interferometer Gravitational Wave Observatory) is used for the detection of gravitational waves caused by cataclysmic cosmic events through multikilometer-scale wave detectors using laser interferometry, L&T explained.

L&T has a total market capitalisation of ₹5.97 lakh crore, as of February 25, 2026, according to data on the NSE.
