The Godavari Marathwada Irrigation Development Corporation (GMIDC) has issued an Expression of Interest (EOI) for the development of a 200 MW Floating Solar PV (FSPV) project integrated with a co-located Battery Energy Storage System (BESS). The project is slated for the reservoir surface of the Purna Project, specifically the Yeldari and Siddheshwar Dams in the Hingoli district of Maharashtra. Prospective bidders must submit proposals under a Public-Private Partnership (PPP) model by the deadline of August 11, 2026.
Key Project Specifications & Scope

| Issuing Authority | Godavari Marathwada Irrigation Development Corporation (GMIDC) |
| Project Type | Floating Solar PV (FSPV) + co-located Battery Energy Storage System (BESS) |
| Capacity | 200 MW |
| BESS Parameters | Base requirement: Minimum 2-hour duration. Storage power capacity requirements vary by source (250% of contracted RE capacity per some announcements; 50% per others); bidders should verify requirements in the final DPR. Modular augmentation to 4-hour duration required if COD slips beyond FY 2029-30. |
| Location | Reservoir surface of Purna Project (Yeldari & Siddheshwar Dams), Hingoli district, Maharashtra |
| Site Area | Approximately 300 Hectares (Feasible water surface area identified at feasibility stage; subject to DPR confirmation) |
| Contract Model | Public-Private Partnership (PPP) |
Scope of Work:
- Design and engineering of the integrated FSPV and BESS facility.
- Supply of all required equipment, modules, and storage components.

Implementation Context: Pradhan Mantri Surya Sarovar Yojana (PM-SSY)
This initiative aligns with the national Pradhan Mantri Surya Sarovar Yojana (PM-SSY) scheme, approved on July 31, 2026. The PM-SSY framework targets the establishment of 5,000 MW of floating solar capacity paired with energy storage across India’s reservoirs to optimize water surface utility and reduce land acquisition requirements. The project supports Maharashtra’s state policy to achieve a 65% renewable energy share in its total electricity demand by FY 2035-36.
Important Timelines & Submission Details
