Faced with rising electricity costs and a commitment to sustainable manufacturing, Prakasa Spectro Cast transitioned from grid power to installing a 750 kW shed-mounted solar system at its facility in Enikepadu, Krishna District, Andhra Pradesh, to fully embrace a green energy initiative.

High power bills from running energy-intensive foundry operations made renewable energy not just an environmental choice, but a strategic financial decision as well. By generating a significant portion of its energy through solar power, the company reduces dependence on the grid, cuts operating costs, and lowers its carbon footprint, aligning its heavy-duty casting operations with global sustainability goals.

Prakasa Spectro Cast manufactures various grades of cast and alloy materials, including cast steel, cast iron, alloy steel, manganese steel, spheroidal graphite iron, nickel-chromium hard cast iron, and high-chrome castings.

The installation by Eshaan Energy features Renewsys Topcon G2G NDCR 600 Wp modules, paired with Sungrow inverters for optimal performance. The mounting system employs aluminum rails, while Polycab AC/DC cables ensure reliable power transmission. The setup also includes customized panels, an 800 V to 33 kV step-up transformer, a vacuum circuit breaker (VCB), and a relay panel to seamlessly integrate solar output into the plant’s electrical network.

Prakasa Spectro’s energy demand used to average 350,000 units per month. With the solar project operational, the company now expects to save approximately 65% on monthly energy bills, achieving a payback period of just five years without interest (six years with interest).

Burra Phani Chandra, Founder and CEO at Eshaan Energy, noted that executing this large-scale solar project required overcoming several challenges. These included changing shed sheets, increasing the height of industrial sheds for better panel placement, navigating policy hurdles related to net metering caps and meter charging, and upgrading connectivity from low-tension to 33 kV using the step-up transformer, VCB, and relay panel.

“Through innovative design adjustments and persistent coordination, Eshaan Energy addressed each hurdle. This successful project execution underscored our commitment to deliver an efficient, long-lasting solar energy system with world-class make and model by elite workmanship,” he said.

Mercom India hosts a multicity ‘C&I Clean Energy Meet’ series designed to provide commercial and industrial energy buyers with the knowledge and tools they need to adopt clean energy solutions and lower their power costs. The next Clean Energy Meet event will be held in Hyderabad on August 22, 2025.
