Companies
BARREL has been promoted and nurtured by its Founder Promoter, Stena Shah, alongside trusted partners who provide technical, management, and strategic support. The group ecosystem spans multiple companies, each aligned to advance energy innovation, sustainability, and community empowerment.
The Manee Foundation
Principle
Across all group companies, a non-dilutable 26% equity stake is permanently embedded for Manee Foundation — a Section 8 non-profit entity promoted by the common promoters of BARREL. This stake cannot be reduced, sold, or transferred under any circumstance, ensuring every group company carries a permanent social dividend that funds education, rural development, and clean energy access for underserved communities.

Project Execution Vehicles
Group SPVs
As mandated by government policy, every energy project requires a dedicated Special Purpose Vehicle. BARREL creates and manages these SPVs through the project lifecycle before transferring them to clients and investors upon completion.
100% Controlled During Execution
BARREL holds 100% of each SPV during project execution — maintaining full control over quality, timelines and compliance throughout the build phase.
Note: Manee Foundation does not hold equity in SPVs, as these are transitional entities created solely for project execution. The 26% Foundation mandate applies only to permanent group companies.
Typical Post-Completion Allocation
- BARREL — Project Developer Retained
- Client (minimum) 26%
- Investor 74%
- Or as mutually agreed Flexible
