Diamond Power Finishes Commissioning 8th MV/EHV Power Cable Production Line

Synopsis: Power infrastructure heavyweight Diamond Power Infrastructure Limited saw its shares lock hard into their upper circuit limit today following a disclosure that the company has successfully commissioned its 8th state-of-the-art Medium Voltage (MV) and Extra High Voltage (EHV) power cable production line at its flagship Vadodara complex, positioning it to capture high-margin market shares.

According to a company announcement dated June 3, 2026, Diamond Power Infrastructure Limited has commissioned its 8th MV/EHV Power Cable Production Line, marking a significant expansion of its manufacturing capacity.

Shares of Diamond Power Infrastructure Limited, with a market capitalization of Rs. 10,054.61 crore, are trading at a price of Rs. 190.80, down 1.98% from their previous closing price of Rs. 194.65. The stock opened at Rs. 193.80 and touched an intraday high of Rs. 193.80 and a low of Rs. 187.11. It is currently trading near its 52-week high of Rs. 211.20, while the 52-week low stands at Rs. 97.70. The company is trading at a P/E ratio of 64.85.

The new manufacturing infrastructure has been integrated directly into the company’s advanced, large-scale engineering facility located in Savli, Vadodara, Gujarat. This new asset addition considerably boosts Diamond Power’s processing capacity for high-specification heavy power cables, positioning the enterprise to meet the shifting demands of modern, high-load industrial utilities and grid-tied distribution projects.

The company’s corporate management highlighted that the operational scaling is intended to capture substantial nationwide capital investment cycles. Medium and Extra High Voltage lines serve as the technological backbone for critical large-scale grid programs, including public utilities, heavy power generation installations, urban underground power transmission networks, and massive renewable energy evacuation systems. 

By expanding its technical infrastructure inside this niche domain, Diamond Power effectively builds upon its competitive entry moats. The MV and EHV manufacturing segment involves complex engineering practices and must strictly adhere to rigorous global quality standards, which creates high regulatory entry barriers for new market entrants.

The timing of this commissioning is highly strategic. The Indian government’s “RDSS” (Revamped Distribution Sector Scheme) and the massive push for Green Energy Corridors have created a supply-demand mismatch for EHV cables. Industry estimates suggest that the domestic EHV cable market is growing at a CAGR of 18%, and with only a handful of players capable of manufacturing high-tension lines, Diamond Power’s 8th line is likely to see immediate high utilization.

Furthermore, the expansion roadmap remains highly active. Commenting on the corporate milestone, Nivedita Pandya, Vice President of Projects at Diamond Power Infrastructure Limited, stated that the commissioning of the 8th line marks an important turning point in the company’s long-term expansion program. She further disclosed that Diamond Power currently has two additional high-capacity production lines under active implementation at the same site, which will continue to strengthen the group’s market share in the premium power cable market.

Order Pipeline

Market participants are closely watching the company’s order book, which currently stands at an estimated ₹1,800+ crore. A significant portion of these orders is tied to state electricity boards (SEBs) and private solar developers who require the exact specifications produced by the new MV/EHV line. This commissioning ensures that the company can accelerate its delivery schedule, potentially leading to front-loaded revenue recognition in the H1 FY27 results.

Company Overview

Diamond Power Infrastructure Limited is a leading, vertically integrated power transmission and distribution equipment manufacturer headquartered in Vadodara, Gujarat. Operating from its massive Savli industrial complex, the group commands deep technical expertise in designing, fabricating, and supplying a highly diversified product suite that ranges from power conductors and transformers to advanced, high-performance medium and extra-high voltage power cables. While most domestic manufacturers focus on Low Voltage (LV) cables where competition is high and margins are thin (8-10%), Diamond Power’s focus on EHV (Extra High Voltage) lines allows it to command margins in the range of 15-20%, effectively insulating it from the price wars seen in the retail cable segment.
