Uttarakhand Power Corporation (UPCL) has floated three tenders for developing standalone battery energy storage systems (BESS) with a cumulative capacity of 100 MW/250 MWh across various substations in Uttarakhand.

The total capacity for Cluster A is 36 MW/90 MWh to be connected at substations in Rudrapur, Kashipur, Haldwani, and Pithhoragarh. Capacity offered for Cluster B at Dehradun (Urban) and Dehradun (Rural) is 23 MW/57.5 MWh, and for Cluster C at Tehri, Haridwar and Roorkeе is 41 MW/102.5 MWh.

The approximate project costs for Cluster A, B, and C are INR 180.50 crore, INR 115.50 crore, and INR 206.30 crore, respectively.

The projects must be set up under the Build, Own and Operate (BOO)model. The projects will be eligible for Viability Gap Funding (VGF) support of up to INR 18 lakh/MWh.

Bidders need to pay INR 29,500 each as a tender document fee for all the three tenders. The processing fee for the tenders for Cluster A, B and C are INR 8.45 lakh, INR 5.40 lakh and INR 9.63 lakh, respectively. Further, they need to furnish INR 3.61 crore for Cluster A, INR 2.31 crore for Cluster B and INR 4.13 crore for Cluster C, as an earnest money deposit (EMD).

The last date for submission of bids is September 15, 2026. The techno-commercial bids will be opened on September 16, 2026.

The selected BESS developer will be responsible for site survey, design, financing, supply, installation, testing, commissioning, operation and maintenance of a grid-connected BESS. The system will provide storage capacity to UPCL for on-demand charging and discharging, based on dispatch instructions from the SLDC/UPCL System Operations Wing.

The complete scope relating to the establishment of the BESS, including its interconnection with the 33 KV UPCL distribution network, shall be the sole responsibility of the BESSD.

UPCL shall provide land within its 33/11 kV substations for installation of the BESS at Right of Use (ROU). Ownership of the land shall remain vested with UPCL, and no right, title, or interest shall be deemed to be transferred to the BESSD.

The primary applications envisaged for the BESS are energy time-shift (arbitrage) and ramping support. However, for increasing the utilisation of the BESS and improving the economic viability, BESS must be capable of other use cases, such as frequency support (ancillary services), capacity upgrade deferral, resource adequacy, and backup supply to critical loads (e.g., black start), etc.

The BESSD must ensure that the BESS installed is of requisite quality as per BESS industry practices and refurbished battery cells are not used in the project.

The BESSD must make the BESS available for 2 operational cycles per day, i.e. 2 complete charge-discharge cycles per day. BESSD must guarantee a minimum system availability of 95 percent on an annual basis.
