Casting the Future in Green: How Bangalore Metallurgicals Forged Ahead with Solar

From engine blocks and valves to turbines and power generation equipment, their products find a home in industries that keep economies moving. With an ISO9002-certified facility in Hoskote, Karnataka, and a reputation for quality, they’re one ofIndia’s most trusted names in the casting industry.

But as a manufacturer supplying both domestic and international markets, Bangalore Metallurgicals knew that staying competitive meant not just producing excellence- but powering it sustainably.

The Challenge

Energy is the lifeblood of casting. And for Bangalore Metallurgicals, it also represented one of the biggest costs.

At nearly ₹10 per unit for grid power, electricity expenses were eating into profitability.The company had already dipped its toes into renewables, with 2 MW of rooftop solar and another 1.6 MW from a different developer, but with expansion came bigger energy needs.

The challenge- How do you scale up power capacity, cut costs, and stay sustainable, without loading your balance sheet with debt?

The Solution

The need for cleaner, cheaper power led Bangalore Metallurgicals to expand their renewable portfolio once again. This time, they chose to go bigger- a 5.5 MWp open-access solar plant with Candi Solar, designed to match their growing demand while keeping financial risks off the books.

Here’s what made the difference:

• PLL Financial Model: The PLL model allows Bangalore Metallurgicals to own the asset - unlocking GST benefits and accelerated depreciation, while paying only for the power generated, giving them the best of both Capex and Opex.

• Zero-Hassle Execution: We handled the approvals upfront from KarnatakaRenewable Energy Development Corporation (KREDL), avoiding the usual regulatory bottlenecks.

• Speed to Power: From Notice to Proceed on April 30th to commissioning onAugust 1st, the project was live in just 103 days, a record turnaround for a project of this scale at Candi.

• Smooth Land Management: With the site owned by just two brothers, we sidestepped land-title and right-of-way delays that often derail large utility projects.

• With every piece falling into place, the foundation was ready for the impact to follow.

The Impact

The results speak for themselves. By replacing costly grid power at nearly ₹10/unit with solar at about half the price, Bangalore Metallurgicals now has immediate breathing room on its energy bills. But the impact isn’t just financial.

This 5.5 MWp system will generate over 9 million kWh of clean energy every year, meeting 81% of their energy demand through solar while also mitigating more than 7,000 tons of CO2 emissions annually, the equivalent of planting 23,000 trees. For a foundry built on heavy industry, that’s a lighter footprint with every casting.

In an energy-intensive sector like iron and auto components, switching to solar also sharpens their competitive edge. Clients in automotive and engineering increasingly expect greener supply chains, and Bangalore Metallurgicals can now meet that demand with confidence.

And at a time when sustainability targets are no longer optional, the shift to clean power positions them as a manufacturer ready for the future, reducing carbon emissions while reinvesting the savings back into growth.

Looking Ahead-

For Bangalore Metallurgicals, solar isn’t just about powering furnaces, it’s about powering the future of Indian manufacturing. With Candi Solar as their partner, they’ve proven that even in industries built on iron, there’s room for a greener, smarter way forward.
