NISE’s 2025 assessment reframes where the sun can power India’s future, and why communication will decide what follows.
- By Mayuri & Nishant
When India last measured its ground-mounted solar potential a decade ago, the map tilted heavily westward, toward Rajasthan and Gujarat.
Now, a new, data-rich assessment by the National Institute of Solar Energy (NISE) under the Ministry of New and Renewable Energy (MNRE) has changed that picture entirely.
The “Solar PV Potential of India: Ground Mounted” report, prepared with support from MNRE, the Ministry of Power, ISRO–NRSC, and State Nodal Agencies, uses high-resolution geospatial data to estimate a technically feasible potential of around 3,343 GWp, spread across 27,571 km² of suitable wasteland.
That’s nearly five times higher than earlier national assessments from the 2010s, not because the sun has grown stronger, but because our data has become smarter.
A New Geography of Possibility for Solar
The study doesn’t just expand the number. It changes the narrative.
Solar viability is no longer confined to the Thar or Kutch.
High-irradiance, terrain-suitable, and infrastructure-ready tracts now appear in central and southern India, regions such as inland Tamil Nadu, parts of Madhya Pradesh’s plateaus, and select districts across Jharkhand and Odisha.
The methodology applies slope and aspect thresholds, satellite-derived irradiance, and a conservative 10 % cap on wasteland utilization per state, ensuring environmental balance even in ambition.
The result is a solar map that feels more democratic: a potential spread across nearly every state, ready to guide district-level planning, grid design, and local investment.
From Data to Decisions
The report doesn’t just present numbers; it sets a new governance standard.
Its transparent, reproducible methods and plan for periodic updates create the base for a publicly accessible, continually refreshed solar potential platform, a kind of national “decision map” where policymakers, financiers, and communities can plan on the same dataset.
That kind of shared baseline changes everything. When planners, regulators, developers, and citizens all see the same map, siting disputes shrink, approvals move faster, and consensus feels possible.
This is where India’s energy story quietly intersects with its communication story.
The Power of Shared Understanding
For years, one of the biggest bottlenecks in renewable expansion hasn’t been technology or finance, it’s trust.
Mistrust between landowners and developers, between state nodal agencies and financiers, or between utilities and communities often stemmed from data gaps and unclear information.
By making technical assessments transparent, NISE’s work effectively builds a communications bridge, from satellite to substation to citizen.
It turns what used to be an opaque policy exercise into a shared planning narrative that can be understood, visualized, and acted upon at every level.
This is strategic communication at its most practical:
- Translating complex GIS data into clear maps and visual explainers.
- Building trust through transparency and consistent updates.
- Enabling states to tell their solar story, backed by credible data, not conjecture.
Beyond the Western Sunbelt
The report also expands India’s energy imagination.
It places sunlight-rich, under-discussed regions like Maharashtra’s dry plateaus or Karnataka’s inland zones on the national radar for investment and integration.
If state governments use this data to align grid infrastructure with feasible solar clusters, they could reduce curtailment risks and cut project timelines drastically.
This is no longer just a climate or energy story, it’s an infrastructure coordination story, where communication, data, and design must move together.
A New Era for Energy Conversations
What makes this assessment transformative isn’t just the 3,343 GWp potential, it’s the clarity it brings.
Clarity that aligns ministries, investors, regulators, and citizens on where India’s solar journey is heading next.
Clarity that can help turn solar potential into permitted, bankable, and socially accepted projects.
Because when data is open, stories align. And when stories align, action follows.
Closing Thought
The Solar PV Potential of India: Ground Mounted report may be a technical document, but it’s also a communication milestone.
It invites India to speak a common energy language – one map, many missions.
For those shaping state policies, corporate solar strategies, or public communication around clean energy transitions, this is much more than information. It’s a new canvas.
And like every great transformation, it will depend not only on how well we plan, but how clearly we communicate.
If you’re part of India’s clean energy ecosystem, and are exploring how to translate data into public trust and momentum, we’d love to hear from you. That’s where strategic communication becomes the quiet power behind the energy transition.
