The last date to submit the bids online is August 27, 2022


Kargil Renewable Energy Development Agency (KREDA) has invited bids for supplying, installing, and commissioning solar tubular (gel type) battery banks of various capacities at locations across the Kargil district in the Union Territory of Ladakh.

The successful bidder will be responsible for the maintenance of battery banks for five years from the date of installation and commissioning of battery banks.

The last date to submit the bids online is August 27, 2022. Bids will be opened on the same day.

Bidders will have to submit an amount equivalent to 2% of the project cost as an earnest money deposit. The successful bidder will be required to furnish a security deposit equivalent to 3% of the value of the contract allotted within 30 days from the date of the purchase order.

The company should be a solar battery manufacturing company in India or a solar engineering, procurement, and construction (EPC) company having an authorized dealership from the original solar battery manufacturing company in India.

Bidders must have ISO 9001 & ISO 14001 certification to design, develop, manufacture, and sell batteries. Bidders who are solar EPC companies should have ISO 9001 & ISO 14001 for quality management of systems. They should have a dealership certificate from the solar battery manufacturing company having ISO 9001 & ISO 14001 certification.

They should have completed a battery bank installation job in Ladakh for a minimum capacity of 500 kWh.

Companies with experience in executing and operating solar power projects or replacing batteries in Ladakh will be given preference during technical evaluation.

The minimum average annual turnover of the bidders during the last three financial years should be at least ₹18.8 million (~$236,261).

The battery bank would be under a comprehensive warranty of five years from the date of commissioning.

If the supplier fails to supply the total quantity or a part thereof within the stipulated time, a penalty of 0.5% per week of the undelivered portion, subject to a maximum of 15% of the cost of the undelivered portion, will be levied.

The battery should be a hi-performance valve-regulated tubular gel type with a polypropylene copolymer container. The battery should be provided with a pressure regulation valve, which should be explosion-proof. The valve unit should be such that it cannot be opened without a proper tool.

The batteries should use 2V and related capacity cells. Their capacity should be designed with an end cell voltage of 1.75 V/cell. The batteries should be suitable for recharging by means of solar modules via solar charge regulators.

In May this year, inverter manufacturer Sungrow announced that it would be supplying its storage solutions to Tata Power Solar Systems’ 60.56 MWh battery energy storage system project at Phyang, in the Leh district of Ladakh. Sungrow said that all equipment and devices would be installed swiftly as the plant is located at an altitude of 3,400 meters above sea level and in harsh geographic conditions.

Earlier, KREDA had issued a tender for 51 solar pumps with a cumulative capacity of 1.153 MW in Kargil. The scope of work included supplying, installing, and commissioning the solar pumps of various ratings at the required locations.
