Maharashtra Invites PPP Bids for 200 MW Floating Solar Project with BESS and 22.5 MW Yeldari Hydroelectric Plant Modernisation
The Water Resources Department of the Government of Maharashtra has invited bids from eligible developers and contractors for two renewable energy projects under the Public-Private Partnership (PPP) model. The projects comprise the modernisation of the existing 22.5 MW Yeldari Hydroelectric Power Plant and the development of a 200 MW Floating Solar Photovoltaic (FSPV) project integrated with a Battery Energy Storage System (BESS) on the Purna Project reservoir.
The tender has been issued by the Executive Engineer, Purna Irrigation Division, Basmathnagar, through E-Tender Notice No. 02 for the financial year 2026–27. The projects are located in Parbhani and Hingoli districts of Maharashtra and are aimed at enhancing renewable energy generation while making efficient use of existing water infrastructure.
Under the first component of the tender, the selected developer will undertake the upgradation, operation, maintenance, and management of the 22.5 MW Yeldari Hydroelectric Power Plant, which forms part of the Purna Irrigation Project. The initiative is intended to improve the plant’s operational efficiency, ensure reliable maintenance, and maximise renewable electricity generation from the existing hydropower asset.
The second component involves the development of a 200 MW Floating Solar Photovoltaic (FSPV) project integrated with a Battery Energy Storage System (BESS) on the reservoir of the Purna Project. The project aims to utilise the reservoir’s water surface for clean energy generation while incorporating battery storage to enhance grid stability and improve the integration of renewable power.
According to the tender schedule, the notice was issued on 24 July 2026. The detailed bid documents will be available from 28 July 2026 to 11 August 2026, while the technical bids are scheduled to be opened on 12 August 2026.
The department has stated that details relating to the Earnest Money Deposit (EMD) and Performance Bank Guarantee (PBG) have not been included in the preliminary tender notice. Interested bidders are required to refer to the complete tender documents available on the Maharashtra Government’s official e-tendering portal for information on bid security, eligibility criteria, financial requirements, and other contractual conditions.
The department has also advised bidders to submit all proposals through the official e-tender portal and to regularly monitor the portal for any corrigenda, amendments, or additional instructions, as no separate notifications will be issued through other communication channels.
The twin projects reflect Maharashtra’s continued focus on expanding its renewable energy portfolio through innovative PPP models that combine hydropower modernisation, floating solar technology, and battery energy storage. The integration of floating solar with an existing reservoir is expected to optimise the utilisation of water infrastructure, strengthen grid reliability through energy storage, and contribute to the state’s clean energy objectives.
