### Adani Order Boosts Diamond Power's Project Pipeline
Diamond Power Infrastructure announced a significant Rs 43.26 crore order from Adani Power Limited. The contract is for supplying power and control cables for Adani's Raipur Phase-II Thermal Power Projects in Chhattisgarh. Design, engineering, manufacturing, and supply are all included, with execution expected by July 31, 2026. Following the news, Diamond Power Infrastructure shares saw a modest rise, trading up 2.83% to Rs 128.43 as of April 6, 2026. The order is domestic and does not involve related parties. This comes as Adani Power is expanding its Raipur Phase-II project, planning to add two 800 MW units and nearly triple its capacity to around 3000 MW.
### Market Growth vs. Diamond Power's Struggles
India's wires and cables market is poised for significant expansion, growing from an estimated ₹92,000 crore (organized segment) in FY24-25 to ₹1.43 lakh crore by FY28-29. This growth is fueled by infrastructure development, renewable energy goals, and grid upgrades. Despite this strong sector outlook, Diamond Power Infrastructure faces a challenging position against industry leaders. Polycab India, the market leader, holds about 27% of the organized segment and has a market capitalization over ₹1 lakh crore with a P/E ratio around 40-45x. KEI Industries, with roughly a 13% share, has a market cap exceeding ₹40,000 crore and a P/E around 45x. Diamond Power Infrastructure's market capitalization is around ₹6.7 billion, yet it trades at a much higher P/E ratio of 63.5 to 66.1x. Adding to these valuation concerns, the company has a negative book value, highlighting its financial difficulties when compared to peers that are largely debt-free and show strong returns.
### Deep-Rooted Issues Undermine Diamond Power
The investment case for Diamond Power Infrastructure is weakened by ongoing structural problems and concerning technical signals. On January 13, 2026, MarketsMojo downgraded the company to 'Strong Sell', pointing to a negative technical outlook and persistent fundamental issues. Technical indicators suggest bearish momentum, with the stock price nearing support levels. The company also has a history of financial difficulties, including undergoing a Corporate Insolvency Resolution Process (CIRP) before being taken over in September 2022, which has led to outstanding legal matters. Regulatory risks related to its public shareholding and corporate governance concerns, such as concentrated ownership and recent board changes, also contribute to the risks. While Sterlite Power Transmission faces its own challenges, Diamond Power's situation stands in contrast to healthier peers like Polycab and KEI, known for strong financials and steady growth.
### Sector Growth Faces Hurdles for Diamond Power
The Indian power infrastructure and cables sector is set for substantial growth, driven by government focus on electrification, integrating renewable energy, and modernizing networks. This indicates strong demand for cable manufacturers. However, Diamond Power Infrastructure's positive industry backdrop is shadowed by its internal struggles. The company's capacity to secure and successfully complete major projects is questioned, given its past financial instability and current negative technical outlook. Although the recent Adani order offers a short-term positive, fundamental and technical challenges suggest investors should be very cautious. It is advisable to look for companies with stronger financial health and more reliable growth paths within this expanding sector.
