India's power sector is booming. Who's paying for it?

Summary: As India continues to rapidly scale its electrification and transmission projects, it is time to shine a spotlight on the players funding the country’s power grids.

It’s hard not to miss the rapid electrification across the country. Be it the cranes, solar panels, transmission towers or substations being built in districts that ran on diesel generators not long ago, India’s power build-out is large, fast and easy to photograph.

However, what’s important to understand is how these projects are run. More importantly, who is funding them?

You see, power projects don't run on ambition. They run on borrowed money. And power players don’t find it easy to raise capital. Reason? The slow nature of cash flows generated by projects through supply contracts and regulated tariffs.

India's plan for its power sector puts hard numbers behind that idea. The country needs roughly Rs 14.54 lakh crore in power infrastructure investment between 2022 and 2027, and another Rs 19.06 lakh crore between 2027 and 2032, for a total of about Rs 33.6 lakh crore. This covers both new generation capacity - solar, wind, hydro, thermal - and the vast transmission network needed to carry that power from where it is made to where it is used. The plan assumes most projects will be funded with roughly 75 per cent debt and 25 per cent equity.

Run that calculation, and you're looking at a multi-decade demand cycle for long-term credit worth tens of lakh crore. That is not a footnote to the electrification story. That is a central chapter of it.

And that is precisely when power financiers stop being background characters.

A history of financial mess

If you followed Indian power sector news in the 2010s, you'll remember what went wrong. Ambitious capacity targets led to aggressive lending. Many projects were delayed or never completed. Distribution companies, or the state utilities that buy electricity from generators and sell it to consumers, ran up large unpaid dues. Generators couldn't service their loans. Lenders were left holding bad assets. The sector became a case study in how quickly infrastructure finance can unravel when execution falters and the payment chain breaks.

But the situation today is materially different in one important way: the stress from the last cycle has largely been worked through. Key lenders have cleaned up their books over several years of hard work, recovering dues, restructuring accounts and being more selective about new lending. Bad loans, as a share of total loans, have fallen sharply. And yet, loan books have kept growing.

This is not what the last cycle looked like. It changes the nature of what investors are looking at, not just a growth story, but a growth story without the overhang of accumulated stress that made the previous one so painful to sit through.

There are three listed companies investors typically use to get exposure to this theme. Each represents a slightly different slice of the same big idea.

The three players financing India’s power ambitions

Power Finance Corporation (PFC): This company is the closest thing India has to a one-stop financier for its power sector - thermal, hydro, transmission and increasingly, renewables. Its total loan book stood at Rs 5.43 lakh crore as of March 2025. 

Gross non-performing assets, or loans where borrowers have stopped paying on time, stood at 1.94 per cent. Net NPA was just 0.39 per cent. For every Rs 100 lent out, less than Rs 2 is showing stress. For a lender this large and this concentrated in one sector, that is a clean number.

The investor question isn't whether PFC will participate in the capex cycle. The sharper question is whether lending to newer renewable and private-sector projects stays this clean as the book evolves.

Rural Electrification Corporation (REC): It runs a nearly identical model to PFC. Its loan book hit Rs 5.67 lakh crore in FY25,  its largest ever. Net credit-impaired assets stood at 0.38 per cent. These are not exciting numbers. That is precisely the point. In project finance, excitement usually arrives later as provisions and write-offs. REC's story is steady compounding, provided the next wave of lending doesn't repeat the old mistake of overconcentrating on a few large, troubled borrowers.

Indian Renewable Energy Development Agency (IREDA): This company is completely different. IREDA primarily lends to renewable energy projects. Its loan book reached Rs 87,975 crore as of December 2025, up nearly 28 per cent from a year earlier. Private-sector borrowers account for 71 per cent of the book. Gross NPA stood at 3.75 per cent - higher than PFC or REC, but partly because the book is younger and newer loans haven't been tested through a full cycle yet.

IREDA is the cleanest way to back the energy transition through a lender. The trade-off: faster growth and strict underwriting discipline are hard to sustain simultaneously. The next two to three years will reveal which one IREDA has prioritised.

The risks that remain

Any honest account of this opportunity needs to spend real time on the risks. These aren't distant possibilities. They are live variables that have caused trouble before.

The most structural is the payment chain. Distribution companies (discoms) buy electricity from generators and sell it to consumers. The problem is that discoms are often financially weak, squeezed between tariffs they can't raise and costs they can't control. When they fall behind on payments, the stress travels up the chain to generators and eventually to lenders. Discom health is, quietly, the foundation on which all of this lending rests - and it remains fragile in several states.

Then there is sector concentration. All three lenders are deeply tied to one sector with no diversification cushion. If power-sector outcomes deteriorate - through policy shifts, project delays, or a return of discom stress - all three feel it together and fully.

Finally, a live policy variable. The Union Budget 2026-27 flagged that the government intends to restructure PFC and REC to improve efficiency. Done well, it could reduce duplication and free up capital. Done badly, it creates uncertainty around strategy and dividends at exactly the moment when steady execution matters most. Not a reason to avoid either company - but a reason to size positions carefully and watch how it unfolds.

A simple way to think about all of this

India is building a power system for the next 50 years. The hardware is visible. But hardware doesn't materialise without financing. Every gigawatt of new capacity, every kilometre of new transmission line, every substation being commissioned in a tier-3 town - each one has a long-term loan behind it.

Power financiers supply that debt. Their books grow when capex grows. Their earnings compound when projects are completed and loans are repaid on schedule. In a multi-decade infrastructure cycle, being the patient lender to that cycle is a durable place to be.

Cables and transformers are the body of the new grid. Debt is its bloodstream. These three lenders are - in their different ways - the institutions keeping that blood moving.

Not a glamorous role. It never was. But in infrastructure, boring and essential tend to go together. And over long periods, essentials tend to win.
