The Rajasthan Renewable Energy Corporation (RREC) has announced a plug-and-play solar park for 2,450 MW solar and 5,000 MWh battery energy storage system (BESS) projects in Pugal, Rajasthan.

The solar park is expected to be commissioned in 2028.  It will be set up at an estimated project cost of ₹13.76 billion (~$155 million).

The blended cost of setting up the solar plus BESS projects at the Pugal solar park will be ₹81.8 million (~$922,254)/MW.

The park will be divided into three lots: Lot 1 (1,000 MW), Lot II (1,000 MW), and Lot III (450 MW).

The 4,353-hectare solar park is being developed by Rajasthan Solar Park Development Company (RSDCL), a subsidiary of RREC.

Projects will be required to maintain a minimum capacity utilization factor (CUF) of 19% and a maximum CUF of 30%. The BESS projects will be set up for a 4-hour single-cycle operation.

Project developers will receive connectivity from the state transmission utility.  They can plug their projects into the designated 33 kV bay inside the park’s pooling stations.

The Rajasthan Vidyut Prasaran Nigam is also developing a 765/400 kV grid sub-station for the solar park.

With the plug-and-play model of solar parks, neither developers face any challenges in obtaining the right-of-way for their projects, nor do they have to deal with land acquisition challenges.

Rajasthan Urja Vikas and IT Nigam will offtake the power generated and sign power purchase agreements with the developers for 25 years.

According to estimates, Rajasthan is expected to experience an average evening peak deficit of 11 GWh by FY 2031. The solar park will focus on procuring power from the projects on a firm and dispatchable renewable energy basis to meet the deficit.

Rajasthan has 24 GW of interstate transmission system (ISTS) connectivity already utilized and 91 GW more expected by 2030. It also has available state-transmission utility connectivity of 23 GW, with an additional 19 GW expected by 2030.

Aligning with the Central Electricity Authority’s mandates, project developers will have to maintain GPS-enabled automatic weather stations.

Tender Details

The government agency will issue a tender for setting up the 2,450 MW solar projects with 1,250 MW/5,000 MWh BESS on November 28, 2025. RSDCL will acquire the land from the state government on a lease basis and sub-lease it to project developers.

Selected project developers will be required to pay ₹3.3 million (~$37 million)/MW for infrastructure and connectivity, and ₹118,000 (~$1,330.39)/hectare for land at the district level committee (DLC) rate. They will also have to pay annual recurring charges for operation and maintenance of the park at ₹230,000 (~$2,593.13)/MW with an annual escalation of 5.85%. The yearly charges will also include a land lease amounting to 7.5% of the DLC rate, with a 5% yearly escalation.

In September 2025, Rajasthan Rajya Vidyut Utpadan Nigam issued requests for proposals to prepare feasibility-cum-detailed project reports for developing solar parks with a cumulative capacity of 31.6 GW across six locations in Rajasthan.
