Indian Solar Sector Sees Major Contracts Awarded For EPC, Consultancy, And Power Cable Supply

Diamond Power Infrastructure has secured a significant power cable supply order from a solar engineering, procurement, and construction firm. The Ahmedabad-based company received a letter of intent from Hild Projects to supply power cables worth ₹661.8 million. The order, scheduled from January 1 to June 30, 2026, follows a kilometre-rate structure with a price variation clause to accommodate changes in material or market costs. Hild Projects, part of Hild Energy, has executed several large-scale solar projects, including a 240 MW NTPC solar plant in Rajasthan and two projects totaling 1,125 MW in Bhuj, Gujarat. Diamond Power manufactures a wide range of cables, including low-voltage, high-voltage, and extra-high-voltage options, as well as specialized solar AC/DC, EV charging, and BESS cables for projects up to 200 kV. Its expanding order book and recent collaboration with US-based TS Conductor underscore the company’s growing role in supporting India’s renewable energy infrastructure.

In another development, Gujarat-based Ahasolar Technologies has won a consultancy contract for an 875 MW solar project from Coal India’s Rajasthan Akshay Urja subsidiary. The project is part of the Rajasthan Rajya Vidyut Utpadan Nigam’s 2,000 MW Solar Park in Pugal, Bikaner. Ahasolar will provide owner’s engineering and project management consultancy over 18 months, reviewing and approving EPC contractor designs, specifications, layouts, and construction schedules. The company will supervise on-site activities, verify quality assurance documents, track progress, and ensure compliance with environmental and social safeguards. The work order, valued at ₹11.8 million, builds on Ahasolar’s prior experience, including a 107 MW consultancy project for Singareni Collieries.

Meanwhile, Solarworld Energy Solutions has won a 250 MW EPC contract from NTPC Renewable Energy Ltd for a solar project in Bikaner, Rajasthan. Valued at ₹7.25 billion, the project includes design, procurement, construction, and three years of operation and maintenance post-commissioning. Solarworld will handle civil and electrical works, grid interfacing, transformer and cable installation, and deploy supervisory control and data acquisition systems, weather monitoring stations, and reactive power compensation equipment. Completion is scheduled in the 2026–27 financial year, further establishing Solarworld’s presence in India’s utility-scale solar sector.

These contracts across supply, consultancy, and EPC segments reflect strong activity in India’s solar energy market, supporting the country’s ongoing renewable energy expansion.
