Diamond Power Infrastructure Limited has received a letter of intent from Adani Energy Solutions Limited for the supply of 4,215 kilometres of AL-59 Zebra Conductor for the Khavda IV-D Project. The order is valued at INR 1,846.6 million and is scheduled to be executed by 31 May 2026, according to information shared by the company.
The purchase order has been awarded on a kilometre-rate basis with a price variation formula. The company stated that the order does not fall under related party transactions and that none of its promoter group companies have any interest in the awarding entity.
The AL-59 Zebra Conductor is a high-performance aluminum alloy conductor made from an aluminum-magnesium-silica (Al-Mg-Si) alloy, known for its 59 percent conductivity. It is designed for power transmission and distribution lines across a wide voltage range, offering superior current carrying capacity, lower DC resistance, and higher corrosion resistance compared to traditional ACSR conductors.
The AL-59 conductor can carry significantly more current (up to around 1307 amperes) than ACSR conductors and reduces line losses due to its lower resistivity. It features better strength-to-weight ratio and lower sag, which optimizes tower designs and improves grid economics, especially in harsh environments like coastal areas.
The AL-59 Zebra variant specifically aligns with standards and specs used in high-voltage transmission lines and offers benefits such as higher ampacity, lower losses, and enhanced durability with a maximum operating temperature of about 95°C. This conductor is favored for modern power grids due to its advanced materials and mechanical properties that lead to improved efficiency and optimization of transmission infrastructure costs.
The Adani Khavda IV-D Project is an inter-state transmission system (ISTS) transmission project acquired by Adani Energy Solutions Limited (AESL) to evacuate 7 GW of renewable energy from the Khavda renewable energy zone in Gujarat, India. The project involves the construction and operation of a 765/400/220 kV substation at Pune-III, along with 765 kV and 400 kV transmission lines and associated equipment. It is implemented under a Build, Own, Operate, and Transfer (BOOT) model, with AESL responsible for the design, financing, construction, operations, and maintenance of the project. AESL will operate the system for 35 years before transferring it to the central transmission utility at no cost.
The project is crucial for facilitating the transmission of renewable power generated at the Khavda Renewable Energy Park, which is planned to be the world’s largest renewable energy park with a planned capacity of 30 GW. This transmission infrastructure will help integrate large amounts of green energy into the national grid, supporting India’s renewable energy targets and decarbonization goals. The project cost is approximately INR 187.8 million, highlighting Adani’s strategic investment in strengthening India’s renewable energy transmission infrastructure.
Diamond Power Infrastructure Limited, also known as Dicabs, is engaged in the manufacturing of conductors, cables, and transmission products. The company has its corporate office in Ahmedabad and its registered office and factory in Vadodara, Gujarat.
