Ahmedabad-based integrated power transmission equipment manufacturer, Diamond Power Infrastructure, has received a letter of intent to supply 33 kV, 2,126 km high-voltage (HV) cables and 3.3 kV, 3,539 km solar medium-voltage (MV) cables worth ₹7.47 billion (~$83.16 million) from Adani Green Energy for its renewable energy project in Khavda, Gujarat, and in Rajasthan.

The company will execute the contract between January and December 2026.

Diamond Power offers low-voltage cables up to 1.1 kV with 34,300 kilometers per annum (KMPA) production capacity, HV cables up to 132 kV with 19,500 KMPA, and extra-high-voltage cables of up to 550 kV with 2,000 KMPA.

The company’s products include 1.1 kV to 66 kV solar AC and DC cables, copper cables, electric vehicle charging cables, special cables for battery energy storage systems (BESS), power and control cables for solar, wind, BESS, hydrogen, and biogas projects of up to 200 kV, and medium voltage covered conductors for renewable energy.

In November this year, Diamond Power Infrastructure received a letter of intent to supply transmission conductors worth ₹2.76 billion (~$30.96 million) from Adani Energy Solutions for the Khavda renewable energy project. The order involves the supply of 7,668 km of AL-59 zebra conductors.

In May, Diamond Power formed a partnership with U.S.-based TS Conductor to support large-scale grid upgrades, reconductoring projects, and renewable energy integration.

In September 2025, Adani Green operationalized 408.1 MW of renewable energy projects at Khavda.

Transmission infrastructure development remains a major bottleneck for renewable energy projects. According to Grid-India’s ‘Operational Feedback on Transmission Constraints (April-June 2025)’ report, a delay of over 18 months in commissioning a transmission system strengthening program has created bottlenecks for evacuating 8.1 GW of power from a renewable energy zone in solar-rich Rajasthan. The Phase II (Parts E, G, and G1) transmission system strengthening project, scheduled for completion in November 2023, remains uncommissioned.
