Rajasthan is set to strengthen its renewable energy infrastructure with the launch of a 2,450 MW solar photovoltaic (PV) initiative at the Pugal Solar Park, alongside a 1,600 MW/6,400 MWh Energy Storage System (ESS) to enhance grid stability and support large-scale renewable integration.
The Rajasthan Solar Park Development Company Limited (RSDCL) has issued a global tender to select developers for the ambitious project. The tender follows a global tariff-based competitive bidding process, employing a single-stage, two-envelope system followed by an e-reverse auction, ensuring transparency and cost efficiency in developer selection.
Chosen developers will be responsible for establishing the solar projects and connecting them to the State Transmission Utility (STU) network. The power generated will primarily be supplied to Rajasthan Urja Vikas and IT Services Limited (RUVITL), contributing to the state’s energy security and sustainability objectives.
The project’s energy storage component is a central feature, designed to store excess solar power and dispatch it during peak demand, thereby improving grid reliability and facilitating integration of intermittent renewable energy. This large-scale ESS positions the Pugal Solar Park as a key milestone in India’s energy transition strategy.
RSDCL has set financial participation requirements for bidders, including an Earnest Money Deposit (EMD) of INR 13,82,000 per MW, a Performance Bank Guarantee (PBG) for the project lifecycle, a non-refundable tender document fee of INR 50,000 plus GST, and a bid processing fee of INR 20,00,000 plus GST.
The tender schedule is clearly defined: registration and document downloads began on 9 January 2026, with a pre-bid meeting on 22 January 2026. Bid submission closes on 9 March 2026, followed by technical bid opening on 12 March 2026, financial bid opening on 3 April 2026, and the e-reverse auction on 10 April 2026. The Letter of Award (LoA) is expected by 21 April 2026, with the Power Purchase Agreement (PPA) and Implementation Support Agreement (ISA) to be signed within 30 days.
The project has a 24-month completion period from the signing of the PPA, and the agreements are expected to remain valid for 25 years post commencement of supply.
Once operational, the Pugal Solar Park and its integrated energy storage system will not only increase Rajasthan’s renewable capacity but also serve as a model for large-scale solar-plus-storage projects across India, supporting the country’s 500 GW renewable energy target by 2030.
