"Uttarakhand is turning up the power on grid flexibility — 250 MWh of standalone battery storage up for grabs in one of India’s largest state-backed BESS tenders!"
Uttarakhand Power Corporation Limited (UPCL) has issued a tender for standalone Battery Energy Storage System (BESS) projects totaling 100 MW/250 MWh across the state. The initiative aims to enhance grid stability, renewable energy integration, and peak load management.
The bid submission deadline is March 10, 2026, with bid opening scheduled for March 11, 2026. This tender represents one of the largest state-backed BESS initiatives in northern India to date.
The tender is divided into three clusters:
1) Cluster A (36 MW/90 MWh): Rudrapur, Kashipur, Haldwani, Pithoragarh
2) Cluster B (23 MW/57.5 MWh): Dehradun (Urban & Rural)
3)Cluster C (41 MW/102.5 MWh): Tehri, Haridwar, Roorkee
Each cluster includes specific financial requirements, including earnest money deposits, performance guarantees, and tender fees, reflecting the scale of investment and developer responsibility.
Scope of Work
● Developers are responsible for:
● Design, engineering, supply, installation, testing, and commissioning of grid-connected BESS projects
● Operation and maintenance over a 12-year contract period
● Integration with UPCL’s 33 kV substations and SCADA-based monitoring
● Deployment of Battery Management Systems (BMS) and Energy Management Systems (EMS), with EMS developed domestically
Projects must meet 95 % availability and ≥85 % AC-to-AC round-trip efficiency, ensuring reliable grid support.
Eligibility Criteria
● Prior experience in ≥63 MWh standalone BESS projects commissioned before March 31, 2025
● OR experience in hybrid solar + BESS projects of equivalent scale
● Demonstrated capability in substation design/construction (400 kV to 33 kV) with operational experience of at least two years
Strategic Significance
The tender underscores Uttarakhand’s commitment to energy storage, renewable energy integration, and grid flexibility. It also reflects India’s broader policy push toward domestic energy storage deployment and encourages private sector participation in large-scale BESS projects.
Timeline
● Bid Submission: March 10, 2026
● Bid Opening: March 11, 2026
● Project Completion: Within 12 months of BESPA signing
● Contract Duration: 12 years
This BESS tender is expected to accelerate India’s energy storage market, attract experienced developers, and strengthen Uttarakhand’s renewable energy infrastructure.
