Group Captive Solar: Why Gujarat Industries Are Shifting
The intent is there. The numbers make sense. So why do most Gujarat manufacturers still pay ₹8 per unit to PGVCL every month — year after year — while watching that number climb every April?
It is not a lack of awareness. Most MDs and CFOs we speak to already know that solar delivers strong ROI. They have seen the calculations. They understand the savings potential.
What stops them is not the decision to go solar. What stops them is the path to get there.
In over 80 MW of solar projects executed across Gujarat, we have seen two barriers kill more solar decisions than any other factor. This blog addresses both — honestly — and explains why an increasing number of Saurashtra and Kutch manufacturers are bypassing both barriers entirely through the Group Captive model.
Barrier 1: Land — The Problem Nobody Talks About Honestly
Ask any manufacturer who has explored captive solar about their experience, and land comes up within the first two minutes.
A solar plant needs the right land — not just any land. It needs to be within a viable distance of a 66KV or 33KV substation. The soil needs to support ground-mount structures. Access roads need to exist or be created. The location needs to be free of transmission line obstructions and clear of flood zones.
Finding land that meets these criteria in Saurashtra or Kutch is not a weekend exercise. It typically requires:
Step 1 — Identification: Surveying multiple parcels, coordinating with local agents, visiting sites, conducting feasibility checks. This alone takes 4 to 8 weeks for a manufacturer who does not have existing land relationships in the right areas.
Step 2 — Acquisition: Once the right land is identified, negotiation begins. Pricing, ownership disputes, fragmented holdings across multiple family members, and sellers who inflate prices the moment they hear the word "solar" — all of this is standard. A clean acquisition in 6 to 8 weeks is considered fast.
Step 3 — Documentation: This is where most manufacturers hit a wall. NA (Non-Agricultural) conversion. Revenue records. Mutation entries. Environmental clearances in some cases. Each step involves the revenue department, local government offices, and legal counsel. Errors at this stage can delay the entire project by months.
The realistic timeline from land identification to documentation completion — assuming everything goes smoothly and no disputes arise — is 4 to 6 months minimum.
For a manufacturer running a business, this is not just a timeline problem. It is a management bandwidth problem. The MD's time, the CFO's attention, the legal team's capacity — all of it gets consumed by a process that has nothing to do with their core business.
Most manufacturers do not give up on solar because the ROI is weak. They give up because the land process demands too much from a team that is already fully deployed running a factory.
Barrier 2: Capital and the Balance Sheet Problem
Let us assume the land problem is solved. The manufacturer now faces the second barrier — and this one is often more decisive.
A 4 MW DC captive solar plant in Gujarat costs approximately ₹15 to ₹20 crore depending on location, equipment specification, and connectivity requirements.
For most manufacturers, this capital does not sit idle waiting for a solar project. It is deployed — in working capital, in raw material inventory, in machinery, or in expansion plans. To invest ₹15 to ₹20 crore in a solar plant, the manufacturer has to either pull capital from the business or borrow from a bank.
If they borrow:
The bank will require additional collateral. For a manufacturer whose assets are already pledged against existing credit facilities, finding fresh mortgage is a real problem. Even if the collateral exists, adding a ₹15 to ₹20 crore loan creates a new liability on the balance sheet. This affects:
The company's debt-to-equity ratio
Future borrowing capacity
Credit rating with existing lenders
Investor perception if the company is listed or planning to raise funds
If they use internal capital:
The manufacturer faces a direct trade-off. ₹15 to ₹20 crore deployed in a solar plant is ₹15 to ₹20 crore not available for a new production line, capacity expansion, or market opportunity.
For a growing manufacturing business, this is not an abstract financial calculation. It is a real strategic choice — and expansion almost always wins over solar. As it should. A manufacturer's core competence is manufacturing, not power generation.
The result: solar gets deferred. One year becomes two. Two becomes five. And every year, the PGVCL tariff revision quietly erodes another ₹10 to ₹15 lakhs of margin.
Why Group Captive Solar Eliminates Both Barriers
The Group Captive model is not a new concept in India's renewable energy sector. What has changed is the structure of how it is being deployed for mid-sized manufacturers in Gujarat — and who is backing it.
Here is how the model works:
The majority investor — a large Indian conglomerate — takes a 74% stake in the Special Purpose Vehicle (SPV) that owns the solar plant. They arrange the land. They fund the majority of the project. They handle the documentation, the connectivity, and the EPC execution.
The manufacturer takes a 26% minority stake. This is the minimum equity required under the Group Captive regulations to qualify as a captive consumer. The capital required for this minority stake is a fraction of what a full captive plant would cost.
The manufacturer signs a Power Purchase Agreement (PPA) with the SPV at a rate significantly below the current PGVCL grid tariff. This rate is fixed for the full tenure of the PPA — typically 25 years.
What this means in practice:
Land: Arranged entirely by the majority investor. The manufacturer does not source, negotiate, acquire, or document a single acre.
Capital: The majority investor funds 74% of the project. The manufacturer's equity outlay is a fraction of ₹15 to ₹20 crore — small enough to fund from internal accruals without touching the bank.
Balance sheet: No large loan. No additional mortgage. No new liability that constrains future borrowing.
Operations: The plant is operated and maintained by professional O&M teams. The manufacturer does not manage a power plant.
The manufacturer's only obligation is their electricity consumption — which they were paying for anyway, at a higher rate, with no control over future revisions.
What This Looks Like in Real Numbers
One of our group captive clients — a manufacturer in Kutch — provides a clear picture of what this model delivers.
Their profile:
Contract demand: 1,500+ KVA on PGVCL's HTP-I tariff
Monthly electricity consumption: 12.85 lakh units
Effective rate: approximately ₹8 per unit
Monthly PGVCL bill: ₹1,10,70,137
After joining as a 26% minority stakeholder in a 4 MW DC group captive plant and signing a 25-year PPA:
January 2026 saving: ₹11,68,019
Projected annual saving: approximately ₹1.22 crore
Projected 25-year saving: ₹30+ crore — before accounting for PGVCL's annual tariff revisions, which make the real number significantly higher
This saving was achieved in month one of operation — without the manufacturer investing in land, without adding debt to their balance sheet, and without diverting capital from their expansion plans.
Who Qualifies for the Group Captive Model
Not every manufacturer qualifies. The Group Captive structure under Indian electricity regulations has specific requirements:
Geography: Must be in the PGVCL discom area — Saurashtra and Kutch districts
Contract demand: 1,500 KVA and above at 11KV
Monthly electricity bill: ₹50 lakhs and above is the practical threshold for meaningful savings
Industry type: Manufacturing units — ceramic, textile, chemical, food processing, engineering, and allied industries
If your unit meets these criteria, the economics of group captive are almost always compelling.
The Honest Question: Why Isn't Everyone Doing This?
Because awareness is low and the right opportunity has not been accessible to most manufacturers.
The Group Captive model requires a credible majority investor — one with the capital, the land relationships, and the track record to execute a multi-megawatt solar project without delays. Finding that investor, structuring the SPV, securing the connectivity, and managing the regulatory process is not something a manufacturer can or should do on their own.
What GRPP does is connect qualifying manufacturers with an established group captive project backed by a century-old Indian conglomerate — eliminating both the land barrier and the capital barrier in a single structure.
The current project under development in Gujarat has limited slots for qualifying offtakers. Once the cohort is complete, the next opportunity is 18 months away.
