Singareni Collieries Invites Bids for Battery Energy Storage System at Solar Project

Telangana (Natural Energy News): Singareni Collieries Company Limited (SCCL), a prominent coal mining company owned by the Government of Telangana and the Government of India, has announced an invitation for bids for a grid-connected Battery Energy Storage System (BESS) of 1 MW/2.5 MWh. This system will be part of the 28 MW solar power project in the Mancherial district of Telangana.

The deadline for bid submission is June 18, 2024, with bids being opened on the same day. The project aims to enhance energy management by storing excess energy generated by the solar plant, which exceeds SCCL’s immediate requirements and is inadvertently transmitted to the Transmission Corporation of Telangana (TSTRANSCO) grid. This stored energy will then be discharged to the SCCL grid at specific times.

Project Scope and Financial Details

The scope of work for this project is extensive, covering design, engineering, supply, packing and forwarding, transportation, unloading, storage, installation, and testing. The successful bidder will also be responsible for the operation and maintenance of the project for ten years. The estimated value of the project is ₹50 million (~$602,004).

To participate, bidders must submit an earnest money deposit (EMD) of ₹500,000 ($6,020). Additionally, within one month of receiving the letter of intent, the successful bidder must provide a performance bank guarantee demonstrating a net worth of ₹50 billion ($602 million) or more for the previous financial year.

Bidding and Transaction Requirements

Bidders are required to pay an e-procurement transaction fee of 0.03% of their quoted value, plus 18% GST on the transaction fee. This fee is capped at ₹10,000 ($120.40) for quoted values up to ₹500 million ($6.02 million) and ₹25,000 (~$301.01) for values exceeding ₹500 million, with GST applied to these capped amounts.

SCCL reserves the right to inspect the items either at the manufacturer’s site or at SCCL’s site. Third-party inspections by entities like RITES may also be employed.

Experience and Operational Criteria

To qualify, bidders must demonstrate experience in the design, engineering, procurement, supply, testing, and commissioning of a BESS of any chemistry. They must have a cumulative installed capacity of at least 200 kW/500 kWh in India or 2 MW/10 MWh overseas. At least one of these projects must be a grid-connected solar project, and another must have a minimum capacity of 50 kW/50 kWh in India or 500 kW/1000 kWh overseas. These systems must have been operational for at least one year prior to 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.

Payment Terms

The tender specifies that 80% of the value of the supply and service part, along with 100% of applicable taxes, duties, cess, and levies, 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 successful BESS installation and commissioning. Payments for operation and maintenance will be released quarterly for up to ten years.

This tender is part of SCCL's ongoing efforts to expand its renewable energy portfolio, as evidenced by its recent tender to appoint a project management consultant for a 67.5 MW solar power project.
