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

From engine blocks and valves to turbines and power generation equipment, theirproducts 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, BangaloreMetallurgicals knew that staying competitive meant not just producing excellence- butpowering it sustainably.

The challenge -

Energy is the lifeblood of casting. And for Bangalore Metallurgicals, it also representedone 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 solarand another 1.6 MW from a different developer, but with expansion came biggerenergy 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 theirrenewable portfolio once again. This time, they chose to go bigger- a 5.5 MWpopen-access solar plant with Candi Solar, designed to match their growing demandwhile keeping financial risks off the books.

Here’s what made the difference:

• PLL Financial Model: The PLL model allows Bangalore Metallurgicals to own theasset- unlocking GST benefits and accelerated depreciation, while paying onlyfor 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 usualregulatory 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 projectof this scale at Candi.

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

• 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 withsolar at about half the price, Bangalore Metallurgicals now has immediate breathingroom 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 than7,000 tons of CO2 emissions annually- the equivalent of planting 23,000 trees. For afoundry 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 alsosharpens their competitive edge. Clients in automotive and engineering increasinglyexpect greener supply chains, and Bangalore Metallurgicals can now meet thatdemand with confidence.

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

Looking Ahead-

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