A power station with no power station
A conventional plant is a place. It has a boundary wall, a control room and a single connection to the grid. A virtual power plant (VPP) has none of that. It is a software layer sitting above thousands of small energy assets that belong to other people — a battery in a factory, panels on a warehouse roof, an EV charger in a basement, a cold store that can hold its temperature for twenty minutes — coordinating them so that, seen from the grid, they behave like one dispatchable machine.
The idea is not complicated. If a grid operator needs 50 MW for two hours, it does not much care whether that comes from one turbine or from ten thousand batteries discharging together. What matters is that the response is predictable, measurable and arrives when called. Producing that reliability out of thousands of independently-owned devices is the entire engineering problem.
What a VPP is actually made of
Strip away the branding and a VPP has four layers.
- The assets. Rooftop solar, behind-the-meter batteries, EV chargers, diesel gensets, pumps, chillers and other flexible loads. They already exist and they already have owners.
- Metering and communications. Every asset needs an interval meter and a data link. Without measurement there is no settlement, and without settlement nobody gets paid.
- The control platform. Software that forecasts what each asset can offer, decides what to call on, sends the instruction and verifies what happened. The literature usually splits this into a technical VPP, handling grid constraints and dispatch, and a commercial VPP, handling bidding and settlement.
- The market interface. The contracts and rules that let the aggregated capability be sold — to a distribution company, to a grid operator buying ancillary services, or into a power exchange.
India is well supplied with the first two layers, improving fast on the third, and still building the fourth.
India has quietly built the raw material
Two numbers explain why VPPs are being discussed here now rather than five years ago.
The first is metering. As of 30 June 2026, India had 7.24 crore smart meters installed — counting consumer, distribution transformer and feeder meters — with 20.33 crore sanctioned overall and 5.73 crore installed under the Revamped Distribution Sector Scheme. A smart meter is the precondition for everything else: it turns a consumer from a monthly bill into a stream of interval data that can be forecast against, dispatched against and settled.
The second is distributed generation. India’s rooftop solar capacity is expected to reach roughly 25–30 GW by FY 2026-27. That is a large fleet of small, weather-dependent generators sitting on the consumer side of the meter — exactly the population a VPP exists to organise. The distinction between consumer-side and grid-side assets matters here, and we set it out in behind-the-meter versus front-of-meter storage.
Utilities have been experimenting with the control layer for some time. Tata Power has worked with AutoGrid on AI-enabled smart energy management in Mumbai, and Tata Power-DDL ran a demand response programme in Delhi between 2022 and 2025 combining automated and behavioural response across residential, commercial and industrial consumers, supported by smart metering.
Why batteries are the part that matters
A VPP built only from solar and flexible load has a structural weakness: it can offer capability only when the sun is shining or when a process genuinely tolerates interruption. It cannot be told to deliver 30 MW at 20:00 on a still evening and reliably do it.
Storage removes that dependency. A battery responds on command, in either direction, regardless of weather or production schedule — which is why every serious VPP design is anchored on aggregated storage rather than aggregated load. The technical requirements now being set for storage in Indian markets show the standard: the CERC draft framework of 30 April 2026 contemplates a minimum 85% round-trip efficiency, minimum 90% availability, response measured in tens of milliseconds, and a 12-year depreciation period for battery assets.
Those specifications are written for large grid-connected systems, but they set the benchmark a pooled fleet must collectively meet. A commercial and industrial cabinet doing peak shaving for its own site already has the responsiveness; what it lacks today is a route to sell that responsiveness to anyone else.
The regulatory gap
This is the honest part of the story. India does not yet have a dedicated virtual power plant framework. There is no settled national rulebook defining what an independent aggregator is, how it qualifies, how pooled consumer-side assets are metered and settled, or how revenue is shared between aggregator and asset owner.
What is moving is the ground beneath it. CERC released draft Power Market (Second Amendment) Regulations, 2026 on 30 April 2026, formalising integrated energy storage systems within market participation and establishing centralised price discovery through market coupling, with GRID-India as market coupling operator and stakeholder comments due by 31 May 2026. Separately, CERC has recognised storage as a regulated asset within both generating stations and the interstate transmission system, and storage has been permitted to provide ancillary services — including secondary and tertiary reserves — since January 2022.
Each of these makes storage a legitimate market participant. None of them yet creates the aggregator licence a consumer-side VPP would need. Expect that to arrive incrementally, and unevenly, through a mix of central regulation and state distribution licensee schemes.
Because market regulations and aggregation rules change by notification and several frameworks above are still in draft, treat the thresholds and dates here as the current direction of travel rather than settled law, and verify the latest CERC and state commission notifications before committing to a business model.

What this means for you
If you are a C&I site owner with a battery or a solar-plus-storage system, a VPP is a future revenue line rather than a present one. The practical step today is to make sure your equipment is not the obstacle: interval metering, an energy management system with an open communication protocol, and a battery whose controls can accept an external dispatch signal. Retrofitting connectivity later is expensive; specifying it now costs almost nothing.
If you are a distribution utility, the pieces are largely in place and the constraint is commercial design — tariffs that reward flexibility, contracts consumers actually understand, and settlement that pays reliably. The demand response pilots already run in Delhi and Mumbai are the template.
If you are a developer or aggregator, the opportunity is real but sequencing matters. Build on assets whose value stands up without VPP revenue — demand charge management and energy arbitrage pay for themselves today — and treat aggregation income as upside when the rules land, not as the basis of the business case.
The simplest way to judge whether storage makes sense at your site on today’s economics, before any VPP revenue is assumed, is to run the numbers on your own tariff and load. Our BESS savings calculator does exactly that, and our team is happy to talk through a specific site.
