- Rajasthan has invited bids for up to 2.45 GW of solar power combined with 1.6 GW/6.4 GWh of battery energy storage at the Pugal Solar Park, with bids due by March 9, 2026.
- The projects will be developed in two lots and must be commissioned within 24 months, building on the state’s recent success in awarding large-scale standalone BESS tenders.
Rajasthan, India, continues to strengthen its commitment to renewable energy. To this end, the state has invited bids for a major solar and energy storage project. Rajasthan Solar Park Development Company Ltd. (RSDCL), a subsidiary of the Rajasthan Renewable Energy Corporation, has launched a competitive tender.
The tender covers up to 2.45 GW of solar photovoltaic capacity. In addition, it includes 1.6 GW/6.4 GWh of battery energy storage systems (BESS). Notably, RSDCL will develop the projects at the Pugal Solar Park in Bikaner district, which remains a key renewable energy hub.
Moreover, RSDCL has fixed March 9, 2026, as the bid submission deadline. At the same time, the company has divided the tender into two development lots. This structure aims to attract broader market participation.
First, the initial lot includes 2 GW of solar capacity combined with 1.32 GW/5.28 GWh of BESS. Developers will construct this capacity across eight plots, each with a capacity of 250 MW. Second, the remaining lot consists of 450 MW of solar power. Alongside this, it includes 280 MW of battery storage, equivalent to 1,120 MWh. Consequently, this lot features two plots of 225 MW each.
Furthermore, the tender clearly defines the project schedule. Developers must commission their projects within 24 months from the effective date of the power purchase agreement. As a result, Rajasthan signals its intent to accelerate renewable deployment.
At the same time, the state aims to expand grid-scale storage. By pairing solar generation with battery storage systems, Rajasthan aims to enhance grid reliability. Additionally, the combination will support peak demand. It will also help manage renewable intermittency more effectively.
Notably, this tender builds on Rajasthan’s recent progress in battery storage procurement. In October 2025, Rajasthan Rajya Vidyut Utpadan Nigam Ltd (RVUNL) awarded a 1 GW/2 GWh standalone BESS project. This project benefited from a viability gap funding scheme.
Shortly afterwards, the state concluded another successful tender in November 2025. That process awarded 500 MW/2,000 MWh of standalone battery storage capacity. Together, these outcomes demonstrate a rising level of investor confidence.
Meanwhile, the current initiative reflects a clear and forward-looking strategy. Rajasthan prioritises timely execution and transparent procurement. Likewise, the state emphasises system integration. Clear milestones strengthen accountability. Similarly, defined project lots offer developers flexibility.
Overall, the combined solar and BESS tender represents a significant step forward. It supports a resilient and low-carbon power system. At the same time, it reinforces Rajasthan’s leadership in India’s clean energy transition.
