While a BESS project of 187.5 MW/750 MWh capacity needs to be connected Maheswaram substation, project 2 with the same capacity must be connected to the Choutuppal substation.
The projects will be set up under a build, own, operate (BOO) model with 15 years’ tenure. The project will be eligible for viability gap funding (VGF) support at INR 18 lakh/MWh.
Bidders need to pay INR 29,500 as a tender document fee. For each of the projects, bidders need to deposit INR 10 lakh (plus GST) as a bid processing fee. Further, they need to furnish INR 5 lakh/MW. Selected bidders need to deposit INR 12.5 lakh/MW as a performance bank guarantee (PBG) before signing the BESPA.
The last date for submission of bids is December 27, 2025. The techno-commercial bids will be opened on December 31, 2025.
The minimum bid size for each location must not be less than the proposed capacity at each location, i.e. 187.5 MW/750 MWh.
The BESSD shall be required to set up a BESS, with the primary objective of making the energy storage facility available to TGDISCOMs 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 the required power for charging the BESS.
The land shall be provided through a right-of-use basis by TGTRANSCO/TGGENCO to the developer, at an annual lease charge of INR 1 per acre per year.
The bidder must ensure that the BESS can charge and discharge with a C-rate of 0.25. Additionally, the BESS must be capable of being charged or discharged in blocks of either 60 MW/240 MWh or 67.5 MW/270 MWh up to the total rated capacity specified at each location/project.
The BESSD must make the BESS available for one operational cycle per day, i.e. one complete charge-discharge cycle (4 Hrs) per day. The BESSD must guarantee a minimum annual average system availability of 95 percent on an annual basis.
The tender proposes to promote only commercially established and operational technologies to minimise the technology risk and to achieve the 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 must be developed indigenously within India.
The net worth of the bidder must be at least INR 75 lakh/MW of the quoted capacity in MW, as on the last date of FY25 or as on the day at least seven days prior to the bid submission deadline.
