Power infrastructure manufacturer Marsons Limited has secured a domestic service contract worth ₹94.8 million from the West Bengal State Electricity Transmission Company Limited. Disclosed under SEBI Regulation 30, the contract requires Marsons to handle the repair, testing, and heavy transportation of high-capacity 50MVA, 132/33 KV power transformers within 12 months.
MUMBAI, India — Power transformer manufacturer Marsons Limited has officially secured a new domestic service contract valued at ₹94.8 million (₹9,48,36,600.00 inclusive of GST). Announcing the development on June 9, 2026, the company confirmed that the contract was awarded by the state-run West Bengal State Electricity Transmission Company Limited (WBSETCL).
The contract covers critical engineering services, including the comprehensive repairing, detailed inspection, and structural testing of high-capacity 50MVA, 132/33 KV power transformers. The infrastructure agreement also includes the logistical management of to-and-fro heavy transportation for the massive equipment units between the utility's regional substations and Marsons' specialized manufacturing facilities.
Technical Scope and Utility Specifications
The servicing contract targets heavy-duty grid infrastructure designed to stabilize transmission loads. The 50MVA (Megavolt-Ampere) transformers operating at a 132/33 KV (Kilovolt) threshold are essential sub-station components that step down high-voltage transmission power to lower distribution voltages safe for regional distribution networks.
According to the official corporate disclosure submitted to Indian stock exchanges, the project is scheduled for completion within a 6-to-12-month execution window. The maintenance protocols will involve full core inspection, insulation oil testing, winding repairs, and high-voltage thermal testing to ensure the refurbished units meet strict grid safety criteria before being re-integrated into the West Bengal state power grid.
Strengthening the Order Book and Market Context
This latest service allocation follows a series of recent major contract wins for Marsons Limited in the domestic power distribution sector. Just days prior, on June 3, 2026, the firm received a larger Letter of Intent worth ₹312.6 million from the Assam Electricity Grid Corporation Limited (AEGCL) for the manufacturing and supply of new 132/33kV, 50MVA power transformers.
The corporate expansion aligns with financial results disclosed by the company’s board on May 22, 2026. For the fourth quarter of the financial year ended March 31, 2026, Marsons' net profit surged to ₹225.78 million, compared to ₹89.88 million in the previous year's corresponding quarter. The board has also recently approved capital expansions to upgrade its technical capacity up to the 400 kV/500 MVA class, aiming to lift total annual production output capability from 12,000 MVA to 26,000 MVA.
Strategic Governance and Market Compliance
In compliance with corporate transparency laws, the order disclosure was formally routed under Regulation 30 of the Securities and Exchange Board of India (SEBI) Listing Obligations and Disclosure Requirements.
Company Secretary Uttara Sharma confirmed in the official exchange filing that the award remains a pure third-party commercial transaction executed at arm's length. The document notes that none of Marsons' promoters, director entities, or broader corporate group companies hold any structural interest or related-party stakes in the state utility awarding the contract.

FAQ Section
1. What does a 50MVA, 132/33 KV transformer actually do in a power grid?
A transformer of this class is a heavy-duty infrastructure asset used at electrical substations. It accepts high-voltage transmission electricity (132 Kilovolts) coming from power plants and steps it down to a lower voltage (33 Kilovolts), making it suitable for safe transit to local distribution networks.
2. Is this order for building new transformers or servicing old ones?
This specific ₹94.8 million contract is strictly an infrastructure services and maintenance order. It requires Marsons to inspect, repair, and test existing transformers already owned by the state utility, including handling the heavy logistics of moving them to and from the repair facilities.
3. How does this contract affect Marsons' current financial outlook?
The contract provides incremental revenue visibility for Marsons' services segment over the next year. It builds upon a strong fourth-quarter financial performance where the company's net quarterly profit rose to ₹225.78 million on the back of expanding domestic utility infrastructure demands.
