UJVNL, a Government of Uttarakhand undertaking, has floated two tenders to set up 15 MW/37.5 MWh standalone Battery Energy Storage Systems (BESS) each in the Udham Singh Nagar and Dehradun districts of Uttarakhand.

The first project will be set up in Khatima, in the district of Udham Sigh Nagar, and the second will be developed at Tiloth, in the Uttarkashi district.

The estimated cost of each project is ₹854.5 million (~$9.45 million).

The last date to submit bids for both tenders is February 25, 2026. Bids will be opened on February 28.

Bidders must submit an earnest money deposit of ₹7.5 million (~$82,918). Successful bidders must furnish a performance bank guarantee of ₹ 18.75 million (~$207,296).

UJVNL has proposed a ceiling tariff of ₹396,747 (~$4,386)/MW/month for both projects.

The Battery Energy Storage Purchase Agreement (BESPA) will be signed between UJVNL and the successful bidders within 30 days of issuance of the Letter of Acceptance (LoA) and will remain in effect for 12 years from the commercial operation date.

The BESS should be designed for interconnection with the nearest 33/11 kV substation of UJVNL at 33kV.

Bidders should be an original equipment manufacturer of containerized BESS, holding an Indian manufacturing license agreement with BESS manufacturers who have supplied a cumulative BESS capacity of at least 100 MWh, and with one reference project of at least 15 MWh capacity successfully commissioned.

Alternatively, bidders must meet at least one of the following criteria:

• They must be engineering, procurement, and construction (EPC) developers of battery energy storage systems (BESS) with at least one commissioned BESS plant of a minimum 20 MWh capacity.
• EPC developers of renewable energy projects with a cumulative commissioned capacity of at least 45 MW.
• EPC developers of a single renewable energy project of at least 15 MW capacity that has been commissioned and has been in operation for a minimum of six months
• EPC developers for the design, engineering, and construction of substations with voltage levels ranging from 400 kV to 33 kV, with a cumulative project cost of at least ₹250 million (~$2.76 million) executed in the last seven years and in operation for at least the last two years.

The net worth of bidders should be at least ₹7.4 million (~$81,813)/MW as on the last date of the previous financial year.

The energy scheduled for discharge in a given cycle during a year should be more than or equal to the minimum dispatchable energy capacity at the end of the year. Successful bidders should guarantee a minimum system availability of 95% on an annual basis.

Recently, UJVNL invited bids for setting up a 30 MW/75 MWh standalone BESS at the Dhakrani Hydro Electric Project in Dehradun district.

Earlier, UJVNL had floated four tenders for setting up a cumulative 17.25 MW of ground-mounted grid-connected solar projects.
