Marsons Limited has received vendor approval from Power Grid Corporation of India Limited (PGCIL) for the supply of power transformers, marking a significant milestone for the company. The disclosure was made pursuant to Regulation 30 of SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, and was intimated to the stock exchanges on May 15, 2026. With this approval, Marsons becomes the only PGCIL-approved Extra High Voltage (EHV) transformer manufacturer across Eastern India and ten neighbouring states — a distinction that underscores the company's standing as the region's premier power equipment manufacturer.

Approval Details

The approval designates Marsons as a registered vendor for power transformers under PGCIL-tendered projects. The key details of the approval, as disclosed under the applicable SEBI regulations, are summarised below:

Regional Significance

With this approval, Marsons is now the only PGCIL-approved EHV transformer manufacturer across the following states and regions, with no other transformer manufacturer in this geography currently holding this distinction:

• West Bengal
• Odisha
• Jharkhand
• Bihar
• Assam
• Meghalaya
• Tripura
• Manipur
• Nagaland
• Mizoram

Eastern India and the northeastern states are at the centre of a major national transmission expansion drive. Power Grid Corporation, as the Central Transmission Utility of India, is executing an ambitious programme to strengthen inter-state and intra-state grid infrastructure across the country, with the eastern and northeastern corridors identified as priority areas given their untapped potential in hydropower, renewable energy integration, and load growth.

The Significance of PGCIL Approval

Power Grid Corporation of India is the apex body of India's power transmission sector and the country's single largest procurer of high-voltage power equipment. Vendor approval by PGCIL is among the most rigorous qualification processes available to any transformer manufacturer in India, covering manufacturing infrastructure, quality management systems, high-voltage test facilities, type-test credentials, and technical capability. For state utilities, electricity boards, and large infrastructure developers across India, PGCIL vendor status is widely regarded as one of the strongest benchmarks of a manufacturer's quality and reliability. Beyond the immediate eastern region opportunity, this approval significantly enhances Marsons' competitive standing with state utilities and transmission corporations across India.

World-Class Manufacturing Credentials

The PGCIL approval is the latest in a series of world-class credentials that Marsons has earned over its 65-year journey. The company operates an NABL-accredited high-voltage laboratory equipped with a Haefely Trench impulse generator rated at 1,600 kV / 80 kJ — one of the most advanced testing facilities of its kind in Eastern India. Its transformers are type-tested up to 160 MVA / 220 kV, and the company holds ISO 9001, ISO 14001, ISO 45001, CE certification, and BIS approval. Marsons exports to the United Kingdom, Europe, Africa, the Middle East, and Bangladesh, and continues to actively expand its high-voltage product range.
