Nokh solar park is a 925 megawatt (MW) solar project being developed in Jaisalmer district of Rajasthan, India.
Rajasthan Solarpark Development Company Limited (RSDCL), a subsidiary of Rajasthan Renewable Energy Corporation (RREC), is developing the project in partnership with National Thermal Power Corporation (NTPC).

An implementation support agreement (ISA) was signed between the companies in February 2020, under which RSDCL will develop the basic infrastructure, while NTPC will develop the solar photovoltaic (PV) projects in the solar park.
The Indian solar park project will involve an investment of more than Rs44.5bn ($589.39m), including Rs40bn ($529.7m) for the development of solar photovoltaic (PV) projects and Rs4.5bn ($59.6m) for the construction of basic infrastructure. It is being developed under the Union Ministry of New and Renewable Energy’s (MNRE) scheme for the development of solar parks and ultra-mega solar power projects and is in line with the Rajasthan Solar Energy Policy, 2011.
Scheduled to be completed by March 2022, the project is expected to contribute Rs185m ($2.4m) a year in the form of development charges to the state exchequer for 25 years. The proceeds will be used to develop the state’s renewable energy and transmission infrastructure.
Nokh solar park location
The solar park site is located at Nokh village in Tehsil Pokaran of Jaisalmer district in the state of Rajasthan.
Rajasthan is one of the most preferable destinations for solar park projects in India due to the availability of the highest number of sunny days in a year, high insolation, private non-agricultural land, and large tracts of government-owned land.
The state government’s Rajasthan Solar Energy Policy 2019 and Rajasthan Wind and Hybrid Energy Policy 2019 also support the investors.
Nokh solar park development
Nokh solar park will have four sections, with three sections of 245MW each being developed in engineering, procurement, and construction (EPC) mode and a 190MW section in developer mode.
The development of 735MW (3x245MW) balance of system package of the project includes site clearance and geotechnical investigation, design, and construction of foundation and erection of module mounting structure (MMS) for PV panels, including fixing and interconnection of PV modules. Other works include design, engineering, manufacturing, supply, transportation, installation, testing, and commissioning of solar PV panels.
The project will also involve the construction of a central monitoring and control station with switchgear room, battery room, supervisory control and data acquisition (SCADA) room, storeroom, and security cabin.
NTPC issued a tender to select developers for the 190MW section of the solar project at Nokh Solar Park in January 2021.
Power transmission details
RSDCL will build four park pooling substations and transmission lines for power evacuation from the Nokh solar park. Power will be transmitted to a 33/220kV pooling station through a 33kV capacity cable and will reach the 765kV Bhadla-II sub-station of Power Grid Corporation of India (PGCIL) from the solar park.
The company will construct 220kV and 132kV transmission lines for the solar park on a turnkey basis in Jaisalmer. Associated electrical equipment, including transformers, panels, protection system, breakers, isolators, and cables required for interfacing with the grid will also be installed.
Development of solar parks in Rajasthan by RSDCL
RSDCL is a special purpose company established for the development and management of solar parks in Rajasthan.
It developed Bhadla solar park, a 2.25GW solar complex, covering more than 14,000 acres in Jodhpur district under the MNRE scheme.
The state government plans to develop more than 1,000MW capacity solar parks in Jodhpur, Jaisalmer, Bikaner, and Barmer districts in a phased manner.
