NTPC Renewable Energy, a wholly-owned subsidiary of NTPC, has reissued the tender for the supply of battery energy storage systems (BESS) for solar power projects at the Khavda Renewable Energy Park in the Kutch region of Gujarat.

The tender was previously issued in November last year.

NTPC Renewable Energy has modified the bid submission date, security amount, and eligibility criteria in the new issue.

The last date to submit the bids is July 27, 2023. Bids will be opened on the same day.

Bidders must submit ₹1 million (~$12,189) as a bid security deposit.

The battery storage should be of a minimum capacity of 250 kW, 1200 kWh until the end of the third year.

The successful bidder will be responsible for the comprehensive operation and maintenance of BESS for three years from commissioning the project’s full capacity.

The scope of work includes design, engineering, manufacturing, supply, packing and forwarding, transportation, unloading storage, installation, testing, and commissioning of BESS for solar power projects at the Khavda Renewable Energy Park.

To be eligible, bidders should have supplied batteries for grid-connected and off-grid BESS of a cumulative installed capacity of at least 150 kW and 150 kWh. Out of this, at least one BESS project should be at least 50 kW and 50 kWh capacity.

The reference BESS project should have been operational for at least six months before the bid opening date.

Alternatively, the bidder as an engineering, procurement, and construction (EPC) contractor should have executed BESS projects, solar projects, wind power projects, and substations for a value of ₹41 million (~$499,733) or more in a single project in the last ten years. The reference project should have been operational for at least months before the bid opening date.

Further, the average annual turnover of bidders should be less than ₹51.5 million (~$627,713) for any three financial years out of the preceding five financial years as of the bid opening date.

If the bidder does not meet the annual turnover criteria, its holding company must meet the stipulated turnover requirements, provided that its net worth is at least equal to or more than its paid-up share capital.

The net worth of bidders on the last day of the preceding financial year should not be less than 100% of the bidder’s paid-up share capital.

NTPC has stated that any bidder from a country that shares a land border with India will be eligible to bid in the tender only if the bidder is registered with the competent authority.

In April this year, NTPC Renewable Energy invited bids for interstate transmission system (ISTS)-connected energy storage projects of 9,000 MWh capacity with a minimum of 1,500 MW capacity to be installed anywhere in India.

Earlier, NTPC Renewable Energy had issued an invitation for bids for the design, engineering, manufacturing, supply, installation, and commissioning of a 250 MW/500 MWh grid-connected standalone BESS near Fatehgarh-III ISTS substation in Rajasthan.
