UJVN, a Government of Uttarakhand undertaking, has invited bids for setting up a 30 MW/75 MWh standalone battery energy storage system (BESS) at the Dhakrani Hydro Electric Project in Dehradun district.

Bids must be submitted by February 25, 2026. Bids will be opened on February 28.

The project will be located near the existing 132/33 kV Dhakrani substation and will be connected at the 33 kV level. The BESS will be developed under a build-own-operate-and-transfer model.

The project is part of a larger three-package program aggregating 60 MW/150 MWh of battery storage capacity and is supported by viability gap funding of ₹1.8 million (~$19,700)/MWh through the Power System Development Fund.

Bidders must furnish an earnest money deposit of ₹15 million (~$164,400), a tender document of ₹5,000 (~$55) plus 18% GST, and a security deposit of ₹500,000 (~$5,480)/MWh, totaling ₹37.5 million (~$411,000) for 75 MWh.

Successful bidders must submit a performance bank guarantee (PBG) of ₹1.25 million (~$13,700)/MW, amounting to ₹37.5 million (~$411,000).

The estimated project cost is ₹1.71 billion (~$18.7 million). The ceiling tariff has been specified at ₹396,747 (~$4,350)/MW per month.

The scope of work includes the design, engineering, supply, installation, testing, commissioning, operation, and maintenance of the 30 MW/75 MWh BESS, including the dedicated transmission system up to the interconnection point at the state transmission utility substation.

The project must be completed within 18 months from the signing of the battery energy storage purchase agreement. Operation and maintenance must be carried out for the full contract period.

Bidders must be original equipment manufacturers of containerized BESS, having supplied a cumulative minimum of 100 MWh of BESS, including at least one successfully commissioned project of 15 MWh or higher.

Alternatively, they should have experience as engineering, procurement, and construction (EPC) contractors of BESS projects with a minimum of 20 MWh commissioned capacity.

EPC contractors/developers for renewable energy projects (solar, wind, or small hydro) with either a cumulative commissioned capacity of 45 MW or a single commissioned project of at least 15 MW, connected at 33 kV or above, and operating satisfactorily for at least six months can also submit bids.

Bidders who have executed EPC works for substations ranging from 33 kV to 400 kV, with a cumulative project value of at least ₹250 million (~$2.74 million) over the past seven years, and operating for a minimum of two years, are also eligible to bid.

Bidders must have a minimum net worth or assets under management of ₹7.4 million (~$81,100)/MW of quoted capacity, along with profitability in at least one of the last three financial years.

Any delays beyond the scheduled commissioning date until actual commissioning will attract liquidated damages. The damages will be calculated based on the delayed capacity and duration of delay.

Selected bidders must maintain a minimum annual availability of 95%. Failing to do so will result in liquidated damages,

In 2023, UJVN floated four tenders for setting up a cumulative 17.25 MW of ground-mounted grid-connected solar projects.
