Inox Wind told the exchanges this morning that it has won a 100 MW turnkey wind order from Indian Oil Corporation worth ₹755 crore. It is a repeat order from IOC, and the scope covers turbine supply, full EPC construction, and 10 years of operations & maintenance after commissioning.

What was announced

The filing came to BSE as a press release under Regulation 30 of SEBI's LODR rules, timestamped 3 September 2026. The key terms:

• Customer: Indian Oil Corporation Ltd — a PSU refiner, buying wind capacity for its own captive/green power needs.
• Size: 100 MW, valued at ₹755 crore. That works out to roughly ₹7.55 crore per MW.
• Scope: "Turnkey" — Inox Wind supplies the wind turbine generators, does the engineering, procurement and construction of the wind farm, and then services it for 10 years.
• Repeat: IOC has ordered from Inox Wind before. Group CEO Kailash Tarachandani called it "a testament to the confidence that leading institutional customers place in our integrated capabilities."

Note what the filing does not say: no state or site was named, no commissioning date, and no revenue-recognition schedule. That matters — see below.

What this type of filing means

This is an order-win disclosure, one of the most common Regulation 30 filings on Indian exchanges. A listed company must tell the exchange about any contract that is "material" to it, so investors all learn about it at the same moment rather than through rumour.

Two things beginners routinely get wrong about order wins:

• An order is not revenue. ₹755 crore does not land in this quarter's P&L. It enters the order book — a backlog of promised work — and converts to revenue only as turbines are delivered and construction milestones are hit, typically over 18–36 months. The 10-year O&M portion trickles in over a decade.
• An order is not profit. The margin depends entirely on what the company committed to build it for. A big order won at a thin price can be worse than no order.

Also worth knowing: "turnkey" vs "equipment supply" are two very different businesses. Equipment supply means you sell the machine and walk away — quick cash, lower risk. Turnkey means you own the whole project until it works — land, roads, grid connection, weather delays, the lot. Turnkey orders carry a bigger rupee value per MW, but tie up far more working capital and can stall on things outside your control.

The business

Inox Wind, part of the INOXGFL Group, is a fully integrated wind energy company. It runs three linked activities:

• Equipment supply — manufacturing wind turbine generators at its own plants (roughly 2.5 GW of annual capacity across three facilities).
• Turnkey / EPC — building the complete wind farm for the customer, which is what this IOC order is.
• O&M — long-term servicing of installed turbines, run through listed sister company Inox Green Energy Services.

So this order touches all three parts of the group at once, rather than one narrow slice. Its total order book stood at 4.4 GW as of the Q1 FY27 update, which management says gives 24–36 months of execution visibility.

Why it matters / potential impact

Size it honestly. ₹755 crore is meaningful but not transformative: it's about 17% of the company's FY26 revenue of ₹4,397 crore, spread over several years. And 100 MW is roughly 2% of an existing 4.4 GW book. This is a useful addition, not a step change.

The customer is the real signal. A repeat order from Indian Oil is a PSU credit — payment risk is low, and PSUs re-order from vendors who delivered last time. For a company whose share price has had a rough year, institutional repeat business is evidence the execution track record is intact.

But there's a tension worth flagging. Inox Wind has been publicly pivoting away from turnkey work toward equipment supply — as of July 2026 about 59% of its third-party order book was equipment-supply, with roughly 40% turnkey. The reason is that EPC revenue recognition depends on site readiness and weather, and it locks up working capital until commissioning. This new IOC win is a turnkey order, i.e. it leans against that pivot. That isn't automatically bad — a high-quality PSU counterparty is exactly the customer you'd accept turnkey risk for — but it's the sort of nuance a headline number hides.

Context on the underlying numbers. Q1 FY27 was soft: revenue ₹814 crore (down 1.5% year-on-year) and net profit ₹64 crore, down about 34%. Management has guided to 75% revenue growth for FY27 with 20–22% EBITDA margins, but says 70–75% of the year's business falls in the second half. That makes FY27 a heavily back-loaded, execution-dependent year — orders like this one are the raw material, but delivery is the test.

Is it expensive?

Inox Wind trades around ₹71 a share, giving a market capitalisation of roughly ₹12,100 crore, on a trailing P/E of about 29x, price-to-book near 1.9x, with ROE of about 6.4% and low debt (debt/equity ~0.25).

Compare with its closest listed peer, Suzlon Energy: market cap roughly ₹62,000 crore — about five times larger — on a trailing P/E near 20x, with ROE around 33% and an order book of about 6.1 GW.

Put plainly: the smaller company is trading at the richer earnings multiple while earning a much lower return on equity and carrying a smaller order book. Inox Wind at ~29x is not cheap on today's earnings — it is priced on the assumption that management's steep FY27 growth guidance is delivered. If that back-loaded second half arrives, the multiple compresses on its own; if it slips, 29x has little cushion. Shares are down roughly 43% so far in 2026 against about 7% for Suzlon, which tells you the market has already been marking down that execution confidence. None of this is a target or a recommendation — it is the arithmetic you'd want in front of you.

Beginner takeaway

An order win is a promise of future work, not money in the bank — always divide it by annual revenue and by the existing order book to see how much it really moves the needle. Here that gives about 17% of one year's sales and roughly 2% of the backlog: good news, modest scale. The more interesting detail is buried in the structure, not the number — this is a turnkey order at a company that has been trying to do less turnkey work.

FAQ

Does an order win mean the stock should jump? Not mechanically. The market reaction depends on whether the order is bigger than expected and what margin it likely carries. Here the shares were up only around 1% in morning trade — a modest, not dramatic, response.

What exactly is an "order book"? It's the total value or capacity of signed work a company has yet to execute. It's a visibility measure — Inox Wind's 4.4 GW is described as 24–36 months of work — but it's a forecast of activity, not guaranteed profit, and orders can be delayed or cancelled.

Why does "turnkey" carry a higher value per MW than just selling turbines? Because you're being paid for far more than the machine: civil works, roads, grid connection, installation and commissioning are all inside the price. Higher revenue per MW, but also more cost, more risk and more cash tied up until the project is finished.

What is a Regulation 30 filing? It's the SEBI rule requiring listed companies to promptly disclose material events — order wins, results, board changes, fundraising — to the stock exchanges, so that all investors get the same information simultaneously.
