Singareni Collieries Invites Bids for 1 MW/2.5 MWh BESS at 28 MW Solar Project

The last date for the submission of bids is June 18, 2024


Singareni Collieries Company (SCCL), a coal mining company owned by the Government of Telangana and the Government of India, has invited bids for a grid-connected battery energy storage system (BESS) of 1MW/2.50 MWh at the 28 MW solar power project in Mancherial district, Telangana.

The last date for the submission of bids is June 18, 2024. Bids will be opened on the same day.

The scope of the work includes designing, engineering, supplying, packing and forwarding, transportation, unloading, storage, installation, and testing. The successful bidder must operate and maintain the project for ten years.

The main objective of the BESS is to store the inadvertent units being transmitted to the Transmission Corporation of Telangana (TSTRANSCO) grid from the solar project. The stored power is then discharged to the SCCL grid at a specified time.

Inadvertent energy units are defined as the additional energy units generated by the solar plant that exceed SCCL’s load requirement at any given time and are exported to the TSTRANSCO grid without being accounted for.

The approximate value of the project is ₹50 million (~$602,004).

Bidders must submit an earnest money deposit (EMD) of ₹500,000 (~$6,020).

Within one month from receipt of the letter of intent, the successful bidder should submit a performance bank guarantee showing proof of net worth of ₹50 billion (~$602 million) and above for the previous financial year.

Bidders must pay an e-procurement transaction fee of 0.03% of their quoted value (based on landed cost) plus 18% GST on the transaction fee.

However, the transaction fee is capped at ₹10,000 (~$120.40) for quoted values up to ₹500 million (~$6.02 million).) and at ₹25,000 (~$301.01) for quoted values over ₹500 million (~$6.02 million). GST is applied to these capped amounts.

SCCL reserves the right to inspect the items inquired about either at the manufacturer’s or SCCL’s site. SCCL may also hire a third party, such as RITES, to conduct these inspections.

Bidders must have experience in the completion of the designing, engineering, procurement, supply, testing, and commissioning of a BESS of any chemistry, with a cumulative installed capacity of at least 200kW/500 kWh in India or 2MW/10 MWh overseas.

Among these projects, at least one BESS must be for a grid-connected solar project, and at least one must have a minimum capacity of 50kW/50 kWh in India or 500kW/1000 kWh overseas.

The systems should have been operational for at least one year before the bid opening date.

If the project was executed for the bidder’s use, a commissioning date certificate from the DISCOM/power procurement agency must be submitted.

The tender has specified that 80% of the value of the supply and service part, along with 100% of applicable taxes, duties, cess, and levies as per the order terms and conditions, will be paid within 30 days from the date of acceptance of the material at SCCL stores. The remaining 20% of the equipment value and 100% of the installation and commissioning charges will be paid within 30 days of the equipment/BESS installation and successful commissioning.

Payments for the O&M will be released every quarter at the end of each quarter for up to ten years.

Recently, SCCL floated a tender to appoint a project management consultant for a 67.5 MW solar power project.
