All bids must include a bid security of ₹100 million ($1.19 million) for Indian bidders and $1.19 million for foreign bidders.

Eligibility Criteria

To qualify, bidders must have experience in manufacturing and supplying batteries for at least 40 MW grid-connected BESS, with at least one system having a capacity of 10 MW or higher. The reference BESS should have been operational for a minimum of six months prior to the bid opening date. Integrators of grid-connected BESS projects meeting these criteria are also eligible to bid.

Indian bidders need to have a technical collaboration agreement, a manufacturing license, or a joint venture with a battery manufacturer. This agreement should remain valid through the operation and maintenance period of the project.

Technical and Financial Requirements

Bidders are required to have executed an industrial project in sectors such as power, steel, oil and gas, petrochemical, fertilizer, cement, coal mining, or other process industries within the last ten years. The value of such projects must be at least ₹1.65 billion (~$19.75 million) in a single project, which should have been operational for at least one year before the bid opening date.

Additionally, bidders must have executed at least one electrical substation of 33 kV or above voltage level, including equipment like 33 kV or higher voltage circuit breakers and power transformers. This substation should have been operational for at least one year prior to the bid opening date.

Financially, bidders must demonstrate an average annual turnover of ₹1.65 billion (~$19.75 million) over the last three financial years. Their net worth on the last day of the most recent financial year should be at least 100% of their paid-up share capital.

Recent and Related Developments

In December, Jayram Industries India secured a contract from NTPC Renewable Energy to commission a 250 kW/1,200 kWh BESS supporting solar power projects at the Khavda Renewable Energy Park in Gujarat. Furthermore, NTPC Renewable Energy previously issued a tender for the design, engineering, manufacturing, supply, installation, and commissioning of a 250 MW/500 MWh grid-connected standalone BESS near the Fatehgarh-III ISTS substation in Rajasthan.


This tender from NTPC represents a major step in expanding India's battery energy storage capabilities, aligning with the country’s broader renewable energy goals. Interested bidders are encouraged to review the detailed requirements and prepare their submissions before the July 18, 2024 deadline.
