Diamond Power Infrastructure has secured a significant contract from Adani Energy Solutions Ltd (AESL) for the supply of AL59 aluminium alloy conductors worth ₹185.16 crore, excluding Goods and Services Tax (GST). The order covers supply of 1,050 km of AL59 Moose conductors for the Tuticorin project and 3,770 km of AL59 Zebra conductors for the Pune-III project. The contract includes comprehensive services such as design, engineering, manufacturing, assembly, testing at the manufacturer's works, packing, dispatch and transportation with transit insurance on a Delivery at Place (DAP) basis. The management stated the order builds on the company's existing relationship with AESL, supports visibility for FY27, and reflects the growth in India's transmission capex cycle.
The order value of ₹185.16 crore includes packing and forwarding charges and freight and transit insurance charges, but excludes GST. As reported by Business Standard, the contract price is based on a variable-price mechanism linked to aluminium London Metal Exchange (LME) prices, aluminium premium and the USD/INR exchange rate. The base pricing has been calculated using an aluminium LME price of $2,550 per metric tonne, a premium of $106 per metric tonne and a USD/INR exchange rate of 87. The final contract value will be determined through the agreed Price Variation (PV) formula based on the average LME and USD/INR rate of the month preceding the scheduled dispatch month. The total contract value, including GST, aggregates to approximately ₹218.49 crore. Deliveries are scheduled over approximately eight months, from July 2026 to February 2027.
Earlier on July 5, Diamond Power Infrastructure secured a supply order valued at ₹435.71 crore (exclusive of GST) for the supply of High Tension (HT) and Low Tension (LT) Power Cables for the 310 MW HYD22 to HYD26 Data Center Projects at Hyderabad. The scope covers the supply of approximately 21.35 lakh meters (over 2,100 km) of cables, with deliveries commencing from the first week of August 2026 and completing in a staggered manner by March 2027. This represents among the larger single cable supply orders in India's data center segment and reinforces the company's position as a preferred supplier of power cables for mission-critical digital infrastructure. India's data center build-out is creating a structural, multi-year demand wave with industry forecasts projecting around 30% growth in 2026 and base-case projections of 4–5 GW by 2030.
The ₹621 crore combined order book represents significant growth in the power transmission and data center segments. As reported by Business Standard, Diamond Power Infrastructure reported a 691.25% year-on-year surge in consolidated net profit to ₹60.61 crore for the quarter ended March 2026, compared with ₹7.66 crore in the corresponding quarter of the previous year. Revenue from operations more than doubled, rising 108.46% to ₹695.87 crore from ₹333.81 crore in the year-ago period. The company has been gradually rebuilding its order book after completing its corporate debt restructuring in recent years, positioning it well to capitalize on India's growing transmission capex cycle and data center infrastructure demand.
