A ₹24 Million Power Bill Saving? Why India's Small Steel Mills Are Still Hesitating
A ₹24 Million Power Bill Saving? Why India’s Small Steel Mills Are Still Hesitating
Renewable power could cut electricity costs dramatically for some smaller steelmakers—but attractive numbers on paper do not always translate into real savings.
For many small steel mills in India, electricity is not a minor overhead.
It can account for as much as 40% of operating costs.
A new industry study says India’s secondary steel producers could reduce annual electricity expenses by as much as 34% by switching part of their power supply to renewable energy.
For some plants, that could mean savings of roughly ₹22–24 million ($250,000–$275,000) per year.
That immediately rAISes a more interesting question:if the economics look this attractive, why are only about 11% of smaller steelmakers currently using renewable electricity?
₹24 Million Is Hard to Ignore
India’s smaller steelmakers produce nearly 40% of the country’s crude steel, making them an important part of the industry rather than a niche segment.
But small and medium-sized mills do not have the same financial flexibility as large steel groups. When electricity and fuel costs rise, margins can be squeezed quickly.
That is why renewable power is becoming interesting for a very practical reason: it may simply be cheaper.
For a small manufacturer, renewable energy is increasingly becoming a margin decision—not just a climate decision.
The economics look attractive, but adoption remains surprisingly low.
So What Is Stopping Them?
The problem is not necessarily a lack of interest.
Smaller manufacturers still face several practical barriers:
And sometimes the renewable electricity exists—but cannot actually be used.
One steel producer in Gujarat told the Associated Press that factories participating in a solar project had at times been asked to cut solar generation by as much as 80% because the local network could not absorb all of the available electricity.
That turns a simple “cheap solar” calculation into a much harder business decision.
The Factory Owner’s Real Question
A manufacturer does not care only about the advertised price per kilowatt-hour.
The real question is: how much money will actually be saved at the end of the year?
Before switching to a new power arrangement, factories need to consider:
- Whether renewable electricity can reliably reach the plant
- How often generation could be curtailed
- Whether solar output matches production hours
- How evening or night shifts will be supplied
- Whether storage or backup power is economically justified
A projected 34% saving is attractive. But the real figure will always depend on the factory, the local grid and the procurement model.
Cheap renewable electricity on paper does not automatically equal lower annual operating costs.
This Is Bigger Than Steel
The same calculation applies to many small and medium-sized manufacturers.
Textile mills, plastics factories, food processors, machinery workshops and building-material producers all face similar pressure from electricity costs.
For these companies, the energy transition may not begin with a carbon target.
It may begin with an electricity bill.
The ₹24 Million Question
Renewable electricity could potentially save some of India’s smaller steelmakers ₹22–24 million every year.
The technology exists. The economics increasingly look attractive. What remains difficult is making financing, regulation and grid access work for businesses that do not have the resources of India’s largest industrial groups.
If a factory can cut one of its biggest operating costs by a third, what is stopping it?
An Industry Perspective
If a factory eventually adds solar, battery storage or additional production capacity, its internal electrical system should also be reviewed. Changes in load and supply can affect transformer loading, switchgear ratings, protection settings and distribution capacity.
Derui Electric supports overseas industrial projects with transformer and switchgear selection based on actual load, voltage levels, operating conditions and future expansion requirements.
Frequently Asked Questions
How much could Indian small steelmakers save with renewable power?
The study estimates potential annual electricity-cost savings of around ₹22–24 million per plant, with reductions of up to 34% in some cases.
Why are more small steel mills not using renewable electricity?
Major barriers include financing, upfront investment, regulatory complexity and uncertainty over grid access and renewable-energy curtailment.
Does a factory need to build its own solar plant?
Not necessarily. Depending on local regulations, factories may use shared renewable projects, open-access procurement or long-term power-purchase arrangements instead of owning the entire generation project.
Should electrical equipment be reviewed when a factory adds solar or storage?
Yes. Significant changes in generation, storage or production load may require engineers to review transformer loading, protection settings, switchgear ratings and distribution capacity.
