Uttarakhand Issues Tender for 16 MW/40 MWh Battery Storage Project in Haridwar

The Uttarakhand Jal Vidyut Nigam Limited (UJVNL), a state government undertaking, has invited bids for the development of a 16 MW/40 MWh battery energy storage system (BESS) at the Pathri substation and hydroelectric project in Haridwar district.

The project will be supported through viability gap funding. Interested bidders must submit their proposals by March 5, 2026, with bid opening scheduled for March 7, 2026.

The estimated cost of the project is Rs 882.4 million (~$9.74 million). Bidders are required to furnish an earnest money deposit of Rs 8 million, along with a document fee of Rs 5,000 plus 18% GST and a processing fee of Rs 400,000 plus 18% GST.

Successful bidders will be required to provide a bank guarantee of Rs 20 million, calculated at Rs 1.25 million per MW, and a payment security deposit of Rs 500,000 per MWh prior to commissioning. They will also enter into a 12-year battery energy storage purchase agreement with UJVNL.

The scope of work includes the design, procurement, installation, testing, operation, and maintenance of the BESS, along with the development of a dedicated transmission network up to the interconnection point. Selected bidders must obtain all necessary approvals, including environmental clearances, water use permissions, and clearance from the Chief Electrical Inspector.

The project mandates a minimum monthly AC-to-AC round-trip efficiency of 85%, and only commercially proven battery technologies may be deployed. Permitted technologies include lead-acid, lithium-ion, solid-state, and flow batteries.

The BESS must be commissioned within 18 months of award. Any delays or failure to meet performance benchmarks, including efficiency norms, will attract liquidated damages.

Eligibility criteria require bidders to meet at least one of several technical qualifications, including prior experience in manufacturing, EPC execution, or development of large-scale BESS or renewable energy projects, as well as experience in substation construction. Financial requirements include a minimum net worth of Rs 7.4 million per MW of quoted capacity and profitability in at least one of the last three financial years.
