For years, industrial decarbonisation was largely discussed in terms of targets — what companies wanted to achieve by 2030, 2040 or 2050.
The conversation is beginning to change.
More often now, we are seeing the physical infrastructure behind those targets being built. Tata Power Renewable Energy Limited’s new captive solar project for Tata Steel in Rajasthan is one such example.
The 72.5 MW project at Kalasar in Bikaner has been developed through TP Vardhman Surya Limited, a subsidiary of Tata Power Renewable Energy Limited (TPREL). It is expected to generate around 166 million units of renewable electricity every year and avoid approximately 118,856 tonnes of carbon emissions annually.
It is a sizeable project, certainly, but the capacity number is probably not the most interesting part of the announcement.
The fact that this is captive renewable power for an energy-intensive industrial consumer is more relevant.
For steel, clean power is becoming a business requirement
Steel is difficult to decarbonise. There is no single switch that can be turned to make a steel plant low-carbon.
Some emissions can be addressed through cleaner electricity. Some will require greater efficiency and electrification. Scrap-based production and circularity have a role. Other parts of the production process will require much deeper technological change.
And then there is hydrogen, which could eventually become important in reducing emissions from ironmaking.
But those technologies do not all have to arrive at the same time.
There is work that can be done today.
Increasing the amount of renewable electricity used by industrial operations is one of the more immediate steps available to companies. Captive projects are particularly interesting because the connection between renewable generation and industrial demand is direct.
For Tata Steel, this project adds another source of clean electricity to its operations. For the wider market, it is another sign that renewable energy procurement is moving closer to the centre of industrial strategy.
That is an important shift.
Companies are no longer looking at renewable energy only through the lens of sustainability reporting. Energy cost, long-term availability, carbon exposure and customer expectations are increasingly part of the same discussion.
For sectors such as steel, cement, chemicals and fertilisers, that discussion is only going to become more important.
There is another detail worth noticing
The project uses 171,360 solar modules manufactured by TP Solar Limited, Tata Power’s own solar manufacturing arm.
This may not attract as much attention as the project capacity, but it points to another part of India’s energy transition that deserves more discussion: manufacturing.
India will install enormous amounts of clean-energy infrastructure over the coming years. The economic value of that transition will depend, in part, on how much of the equipment behind it is manufactured domestically.
We have already seen this conversation play out in solar.
It is now beginning in green hydrogen as well.
As hydrogen projects move from announcements towards procurement and construction, questions around electrolyser manufacturing, balance-of-plant equipment, storage, compression, power electronics and engineering capability will become increasingly important.
There is a difference between being a large market for clean technology and building an industry around it.
India clearly wants to do both.
So where does green hydrogen fit?
Not directly into this project.
This is a solar project, and it should be viewed as such.
But it is difficult to have a serious conversation about the future of green hydrogen in steel without first talking about renewable electricity.
Producing green hydrogen at industrial scale requires large quantities of clean power. If hydrogen-based steelmaking is to become commercially meaningful in India over time, the availability and cost of renewable electricity will sit very close to the heart of the economics.
In other words, the renewable-energy build-out taking place today is also creating part of the infrastructure on which tomorrow’s green hydrogen economy will depend.
That doesn’t mean every solar project becomes a hydrogen story.
It means the two transitions are connected.
For steel companies, the journey is likely to be gradual. More renewable electricity can be introduced into existing operations now. Efficiency can improve. Processes can be electrified where it makes technical and commercial sense. New technologies can then be brought in as they mature and become affordable.
Hydrogen will have to earn its place within that mix.
Its role will depend not simply on whether the technology works, but on whether companies can secure sufficient green hydrogen at a price that makes industrial sense.
That remains one of the biggest questions facing the sector.
And this is where scale starts to matter
A 72.5 MW project is useful. India’s industrial requirement, however, will be considerably larger.
TPREL says its renewable utility portfolio has now reached 12.3 GW, with around 7 GW operational and another 5.3 GW under various stages of implementation.
Those numbers give some indication of the pace at which the renewable market itself is growing.
Industrial demand will grow alongside it.
India wants to expand manufacturing. It wants more renewable energy. It wants to produce green hydrogen and green ammonia. It is also looking at low-carbon steel, cleaner mobility, energy storage and new energy-intensive industries.
All of these ambitions eventually meet at one place: the power system.
Can enough renewable electricity be built?
Can it be delivered where industry needs it?
Can supply become reliable enough for industrial operations?
And, critically, can it remain affordable?
These are less exciting questions than announcing a new technology. They are also the questions that will determine how quickly industrial decarbonisation actually happens.
The Tata Steel project does not answer them. Nor is a single project supposed to.
What it does provide is another example of an industrial company putting renewable capacity behind its decarbonisation plans rather than waiting for the entire technology landscape to settle.
That is probably how much of India’s industrial transition will happen — not through one dramatic change, but through a succession of investment decisions made over many years.
Some will involve solar and wind.
Some will involve storage and electrification.
And some, particularly in hard-to-abate industries, may increasingly involve green hydrogen.
For the hydrogen industry, that is worth paying attention to.
Because before green hydrogen can become a serious industrial fuel or feedstock, the clean electricity needed to produce it has to exist at enormous scale.
Projects such as Tata Steel’s 72.5 MW captive solar plant are a reminder that part of that groundwork is already being laid.
FAQs
1. What is Tata Steel’s new captive solar project?
Tata Power Renewable Energy Limited has commissioned a 72.5 MW captive solar project at Kalasar in Bikaner, Rajasthan, to supply renewable electricity for Tata Steel.
2. How much renewable electricity will the project generate?
The project is expected to generate approximately 166 million units of green electricity annually.
3. How much carbon emission could the project avoid?
According to Tata Power, the project is expected to offset around 118,856 tonnes of carbon emissions each year.
4. Why is captive renewable energy important for the steel industry?
Steelmaking is highly energy intensive. Increasing the share of renewable electricity used by industrial operations can help reduce emissions while also building the clean-power foundation needed for deeper decarbonisation technologies.
5. Is the Tata Steel solar project a green hydrogen project?
No. It is a captive solar-power project. Its relevance to green hydrogen is indirect: large-scale green hydrogen production depends on renewable electricity, making clean-power availability an important part of future hydrogen-based industrial pathways.
6. What role could green hydrogen play in steel decarbonisation?
Green hydrogen could eventually help reduce emissions in parts of steelmaking that are difficult to electrify directly, including hydrogen-based direct reduced iron pathways. Commercial adoption will depend on hydrogen cost, renewable-power availability, infrastructure and technology economics.
7. Why does this project matter to India’s wider industrial transition?
It illustrates a broader shift from corporate decarbonisation commitments towards dedicated clean-energy assets serving industrial demand. Replicating such investments across energy-intensive industries will be important as India expands manufacturing while working to reduce its emissions intensity.
