Tata Power commissions captive solar energy project in Bikaner
Source:renewable-watch ↗
Why It Matters
This development underscores the transition of Rajasthan's Bikaner region into a critical solar power hub for both grid-scale and industrial captive projects. It highlights corporate-led decarbonisation strategies (e.g., Tata Steel's captive solar procurement) and showcases advancements in domestic solar module manufacturing and firm, dispatchable renewable energy (FDRE) configurations.
Summary
Tata Power Renewable Energy Limited (TPREL) has commissioned a 72.5 MW captive solar energy project at Kalasar in Bikaner, Rajasthan, to supply green power to Tata Steel Limited. Developed by TPREL subsidiary TP Vardhman Surya Limited using in-house manufactured TP Solar modules, the project will generate 166 MUs of electricity annually and offset around 118,856 tonnes of carbon emissions. The commissioning highlights Bikaner's rapid development as a renewable energy hub, adding to TPREL's growing portfolio of 12.3 GW of renewable assets.
Key Points
- Tata Power Renewable Energy Limited (TPREL) commissioned a 72.5 MW captive solar power project at Kalasar in Bikaner, Rajasthan, for Tata Steel Limited.
- The project was developed via TPREL's subsidiary, TP Vardhman Surya Limited, and is estimated to generate 166 Million Units (MUs) of clean energy annually.
- It is expected to reduce carbon dioxide emissions by approximately 118,856 tonnes every year.
- The plant utilizes 171,360 solar modules manufactured in-house by TP Solar Limited.
- This project pushes TPREL's total renewable capacity to 12.3 GW, with 7 GW operational (5.7 GW solar, 1.3 GW wind) and 5.3 GW under progress.
- Earlier in August 2026, TPREL also commissioned a 190.5 MW solar Firm and Dispatchable Renewable Energy (FDRE) project at the same location (Kalasar, Bikaner) under SJVN's FDRE Tranche-1.

Prelims Trap
The Kalasar project is a state-utility solar park developed to supply grid electricity to Rajasthan state discoms.
Aspirants often confuse private 'captive' solar setups developed for specific industrial giants with public solar parks (like Bhadla) meant for state utility/discom grid distribution.
Static Concepts Connected
What are key provisions of Rajasthan's Solar Energy Policy 2019?
- Target Capacity: Aims to achieve a target of 30 GW (30,000 MW) solar power capacity in the state by FY 2024-25.
- Captive Use: Promotes captive solar plants by offering exemptions on electricity duty and facilitating third-party open access.
- Land Concessions: Simplifies land allocation of government wasteland at concessional rates, driving projects in districts like Bikaner and Jaisalmer.
What is Firm and Dispatchable Renewable Energy (FDRE)?
- Grid Stability: Combines solar or wind power with energy storage systems to deliver stable, non-intermittent renewable power.
- Demand Matching: Mimics conventional power generation, allowing distribution companies to meet peak demand hours reliably without grid fluctuations.
Cross-Topic Patterns
Captive RE + Industrial Decarbonisation
Captive solar projects in Rajasthan's wastelands enable heavy industries like steel to meet mandatory Renewable Purchase Obligations (RPO) and decarbonise energy-intensive manufacturing.
Western Wastelands + Green Transmission
Solar expansion into Bikaner highlights the geography of desert wasteland utilization coupled with the Phase-II Green Energy Corridor for interstate power evacuation.
RPSC may target Bikaner's emerging solar hubs and captive power exemptions in multi-statement questions on Rajasthan's energy sector.
