- Project-7: Gajuwaka SS with a capacity of 25 MW/50 MWh - INR 1 lakh
The BESS developer must set up, operate and maintain a Battery Energy Storage System (BESS), with the primary objective of making the energy storage facility available to State DISCOMs/ SLDC for charging/discharging of the BESS, on an ‘on demand’ basis.
Setting up of the BESS and interconnection of the BESS with the State Transmission Utility (STU) network and entire operation and maintenance including safety of the equipment/personnel will be under the scope of the BESSD.
Scheduling of charging and discharging of the system will be under the scope of SLDC/DISCOMs. The State DISCOMs will provide required power for charging BESS.
The bidder is required to design the BESS, ensuring that the BESS can charge and discharge with a C-rate of 0.5. Additionally, the BESS must be capable of being charged or discharged in blocks of either 50 MW/100 MWh or 75 MW/150 MWh. Each BESS block must be operated independently to comply DISCOMs/SLDC instructions.
The BESSD must guarantee a minimum annual average system availability of 95 percent on annual basis.
The land shall be provided through Right-of-Use basis by APTRANSCO to the developer, at an annual lease charge of INR 1 per acre per year.
The RfS proposes to promote only commercially established and operational technologies to minimise the technology risk and to achieve timely commissioning of the project. Further, the BESSD must ensure that refurbished battery cells are not used in the project and the application software of the Energy Management System (EMS) of the BESS shall be developed indigenously within India.
As for financial eligibility, the net worth of the bidder must be at least INR 30 lakh/MWh as on the last date of FY 2024-25 or as on the day at least 7 days prior to the bid submission deadline.
