Tata Power Powers Rajasthan With 190 MW Renewable + Storage Breakthrough

Tata Power Renewable Energy Limited (TPREL) has commissioned a landmark 190.5 MW Firm and Dispatchable Renewable Energy (FDRE) project at Kalasar, Bikaner, Rajasthan. Integrated with a 115 MWh Battery Energy Storage System (BESS), the project ensures reliable, round-the-clock renewable power supply to key state discoms.

Firm and Dispatchable Renewable Energy (FDRE) is renewable power engineered to behave like conventional electricity — combining solar, wind, and battery storage to deliver reliable, schedulable supply that utilities can depend on, including during peak demand hours.

FDRE represents the second phase of India’s renewable energy journey: moving from capacity addition to dependability. With installed solar capacity crossing 150 GW in March 2026, FDRE ensures that this massive renewable base can be harnessed in a way utilities can plan around. It is now one of the defining procurement formats in India’s utility‑scale renewable energy market.

Project Overview

• Capacity: 190.5 MW FDRE (part of a larger 460 MW FDRE initiative under SJVN FDRE Tranche-1)
• Location: Kalasar, Bikaner, Rajasthan
• Technology: Advanced Battery Energy Storage System (115 MWh), Harmonic Filter Bank, and Static Var Generator systems
• Beneficiaries: Haryana Power Purchase Centre (HPPC), Maharashtra State Electricity Distribution Company (MSEDCL), and Noida Power Company Limited (NPCL)

Strategic Significance

• Reliable Renewable Supply: FDRE projects overcome intermittency by combining solar with storage, ensuring dispatchable clean energy
• Portfolio Expansion: TPREL’s renewable capacity now stands at 12.4 GW (6.9 GW operational: 5.6 GW solar + 1.3 GW wind; 5.5 GW under implementation)
• National Targets: Supports India’s 500 GW non-fossil fuel capacity goal by 2030 and Tata Power’s Net Zero by 2045 commitment
• Execution Excellence: Despite global supply chain challenges, Tata Power completed the switchyard in 3 months and harmonic filter bank in 1 month
