InvITs Explained: Infrastructure Investment Trusts For Indian Retail Investors

Last Reviewed and Updated: 17 Aug 2026

An Infrastructure Investment Trust pools money from many investors to own and operate infrastructure assets, roads, power transmission networks, renewable energy installations, and gas pipelines among them, and lists units representing that ownership on a stock exchange, structurally very close to how a REIT works, just built around infrastructure instead of real estate.

Every InvIT runs on a four tier structure: a Sponsor, the company that sets up the trust and transfers assets into it, commonly a large infrastructure developer or a public sector entity like NHAI or Power Grid Corporation; a Trustee, a SEBI registered entity that holds the assets in trust on behalf of unit holders; an Investment Manager, responsible for strategy and acquisitions; and a Project Manager, responsible for day to day operations and maintenance of the underlying assets.

Only 7 Of India's 27-Plus InvITs Are Actually Available To You

Most InvITs in India are privately placed vehicles, raising capital from institutional investors directly rather than through a public listing, and are simply not something a retail investor can buy on an exchange.

A regulatory pathway does exist for a privately placed InvIT to list publicly later, which is how some current public names first became tradeable, but the large majority of the 27 InvITs operating in India today remain outside public markets entirely.

Why Revenue Models Differ So Much Within This One Category

Almost every Indian REIT earns broadly similar income, rent from office or retail tenants. InvITs do not share that consistency, because the infrastructure assets underneath them generate revenue in genuinely different ways depending on what they actually are.

PowerGrid InvIT's transmission assets operate under long term Tariff Service Agreements, in some cases running 25 years, which pay a largely fixed rate regardless of how much electricity actually flows through the lines, a stable, close to bond like revenue model.

Toll road assets, the kind IRB InvIT Fund and National Highways Infra Trust hold, work differently: revenue depends directly on how much traffic actually uses a specific stretch of highway, a genuinely variable, usage linked income source.

That structural difference shows up directly in yields, with PowerGrid InvIT's more predictable model commonly yielding around 6% to 7%, and IRB InvIT Fund's traffic exposed model commonly yielding 10% to 11%, based on recent distribution data.

Revenue Model	Example	Typical Yield Range
Regulated, tariff based	PowerGrid InvIT, long term Tariff Service Agreements with largely fixed payments	Roughly 6% to 7%
Traffic or usage linked	IRB InvIT Fund, revenue tied to actual highway traffic volumes	Roughly 10% to 11%

Yields are indicative, based on recent distribution data, and move as unit prices and actual distributions change. A higher yield here generally reflects greater revenue variability, not simply a better deal.

A power transmission InvIT and a toll road InvIT both call themselves InvITs. One earns a number the regulator has already agreed to pay it. The other earns whatever traffic happens to show up.

The Return Of Capital Wrinkle, Specifically For Toll Roads

For toll road InvITs specifically, part of each distribution can reflect a return of capital rather than freshly earned income, effectively the trust returning money tied to a depreciating physical asset rather than paying out a return generated on top of your original investment.

That distinction matters before treating a headline 10% to 11% yield as directly comparable to a bond coupon of the same size, since part of that figure may be your own principal coming back to you over time rather than income earned on it.

Our earlier article on REITs covers the fuller tax breakdown that applies to distributions built from interest, dividend, and return of capital components, a mechanism InvITs largely share.

A Concrete Look At Two Very Different InvITs

IndiGrid owns 38 operating projects, including 53 extra high voltage transmission lines and 1,155 megawatts of solar generation capacity, spanning more than 9,300 kilometres of circuit length and 16 substations across 20 states.

Its average residual contract length runs around 25.7 years for its transmission assets and 19.6 years for its solar assets, illustrating the long duration, regulated end of the InvIT spectrum.

IRB InvIT Fund, India's first listed InvIT, holds 9 highway assets across 5 states, with a weighted average residual concession period of roughly 17 years, and continues actively acquiring new road assets, including a highway asset worth roughly Rs 1,200 crore added in February 2026 alone. Its portfolio illustrates the more actively managed, traffic exposed end of the same category.

	IndiGrid	IRB InvIT Fund
Asset type	Power transmission and solar generation	Toll road highways
Scale	38 operating projects, over 9,300 km of circuit length, 20 states	9 highway assets across 5 states
Average residual contract or concession length	Roughly 25.7 years (transmission), 19.6 years (solar)	Roughly 17 years, weighted average
Revenue character	Largely fixed, long term tariff agreements	Variable, tied to actual traffic volumes

The minimum trading lot for most publicly listed InvITs has been reduced to a single unit, following the same reform pattern applied to REITs. Buying units works exactly like buying any listed stock, through an ordinary demat account, searching the specific exchange symbol, IRBINVIT, PGINVIT, or INDIGRID among them. Distributions are typically paid quarterly, credited directly to a linked bank account.

The Policy Backdrop

India's Asset Monetization Plan, running through 2025 to 2030, is actively using InvITs as a vehicle for unlocking value from national highways, power grids, and other public infrastructure, transferring completed, revenue generating assets into trust structures rather than leaving them entirely on government or public sector balance sheets.

That policy push suggests the pipeline of new InvIT listings, and additional asset transfers into existing ones, is likely to keep growing over the next several years, rather than this being a settled, static category.

The Risks Particular To This Asset Class

● Usage risk. Toll road and similar traffic linked assets carry revenue that depends on factors entirely outside the trust's own control, actual vehicle volumes on a specific stretch of road.

● Regulatory and tariff risk. Assets earning regulated income depend on rates set or approved by a regulator, and any future change to that regulatory framework directly affects distributions.

● Leverage. InvITs often carry meaningful debt to fund asset acquisitions, and higher leverage increases sensitivity to interest rate changes and refinancing conditions.

● Concentration. Many InvITs hold a relatively small number of large, single purpose assets, unlike a diversified equity fund spread across many companies.

● Interest rate sensitivity, shared with REITs, since income focused instruments in general tend to face pressure when interest rates rise and fixed income alternatives become relatively more attractive.

Note: India currently has 27 InvITs, but only 6 are publicly listed and available to an ordinary retail investor. The other 21 are privately placed, institutional only vehicles, a distinction that does not really exist in the REIT space, where every Indian REIT is publicly listed. Our earlier article on REITs covers the shared mechanics both structures rely on, the 90% minimum distribution mandate, demat based trading, and the broad tax framework, which this article does not repeat in full.
