Tata Power Renewables Delivers 1 GW DCR Solar Project for SJVN in Rajasthan

Tata Power Renewable Energy Ltd. (TPREL), a wholly owned subsidiary of The Tata Power Company Ltd., has completed and commissioned a 1 GW domestic content requirement (DCR)–compliant solar power project for SJVN Ltd., marking the largest engineering, procurement, and construction (EPC) assignment executed by the company to date.

The utility-scale solar installation, with a capacity of 1,000 MW AC (1,400 MWp DC), has been developed across the Bandarwala and Karnisar Bhatiyan locations in Bikaner district, Rajasthan. One of the country’s largest solar projects, it will supply clean electricity to multiple states, including Rajasthan, Jammu and Kashmir, and Uttarakhand.

All 2.4 million solar modules used in the project were produced at TP Solar Ltd.’s fully integrated solar cell and module manufacturing facility in Tirunelveli, Tamil Nadu. This deployment underscores Tata Power’s focus on strengthening domestic manufacturing capabilities and supporting the Government of India’s Make in India programme.

The generated capacity has been allocated among several state utilities, with 500 MW contracted to Rajasthan Urja Vikas and IT Services Limited (RUVITL), 300 MW to Jammu and Kashmir Power Limited (JKPL), and 200 MW to Uttarakhand Power Corporation Limited (UPCL).

During its first year of operation, the solar plant is expected to generate around 2,454.84 million units of renewable electricity, helping avoid approximately 1.74 million tonnes of carbon dioxide emissions. The project contributes directly to India’s clean energy transition and long-term decarbonisation goals.

Engineered to perform reliably under extreme climatic conditions—ranging from summer temperatures of up to 50°C to winter lows of around 3°C—the project incorporates advanced DCR-compliant solar cells, mono bifacial DCR modules, precision ramming techniques, and high-efficiency inverters to maximise energy output and operational stability.

In addition to its environmental impact, the project has delivered notable socio-economic benefits. More than 300 local workers were engaged during execution, and over 25 local vendors were developed, supporting sustained employment and economic activity in the region.

Following this commissioning, TPREL’s total utility-scale renewable energy portfolio has expanded to 11.6 GW, including 4.9 GW executed as third-party EPC projects. Tata Power currently operates 5.8 GW of its own renewable capacity—comprising 4.7 GW of solar and 1.1 GW of wind energy—with an additional 5.8 GW under various stages of development.
