What is Group Captive Solar Power?
Group Captive Solar Power is a renewable energy model where multiple commercial or industrial consumers jointly own and utilize power generated from a solar plant.
Typically, participants invest through a Special Purpose Vehicle (SPV) that owns and operates the solar project.
Key Regulatory Requirements
To qualify as a Group Captive project under Indian regulations:
- Consumers must collectively own at least 26% equity in the SPV.
- Participating consumers must collectively consume at least 51% of the annual electricity generated.
The model operates through Open Access mechanisms, enabling electricity generated at an off-site solar plant to be delivered through the grid to participating consumers. :contentReference[oaicite:1]{index=1}

How the Group Captive Model Works
Step 1: Formation of an SPV
A Special Purpose Vehicle (SPV) is created to develop, own, and operate the solar project.
The participating consumers collectively own at least 26% of the SPV.
Step 2: Equity Participation
Each participant invests capital in proportion to its planned electricity consumption.
This ensures fair allocation of power generation benefits.
Step 3: Power Purchase Agreements (PPAs)
Each consumer signs a Power Purchase Agreement outlining:
- Tariff structure
- Power allocation
- Contract duration
- Rights and obligations
Step 4: Open Access Approvals
The SPV obtains required approvals from relevant electricity authorities to transmit electricity through the grid.
Step 5: Energy Delivery and Billing
Electricity generated by the solar plant is delivered through the grid to participating consumers.
Consumers pay based on their agreed allocation while benefiting from reduced electricity costs. :contentReference[oaicite:4]{index=4}
