The Uttar Pradesh Power Corporation Limited (UPPCL), under the Government of Uttar Pradesh, has issued a tender on August 12, 2024, seeking to engage Battery Energy Storage System Developers (BESSDs) for the deployment of a 1200 MWh (300 MW x 4 hours) Battery Energy Storage System (BESS) at two strategic load centers across the state. The project aims to provide "on-demand" energy storage services, leveraging the Build-Own-Operate-Transfer (BOOT) model under a Tariff-based Competitive Bidding process. The pre-bid and final submission dates for this tender are expected to be clarified by UPPCL.
The tender outlines critical responsibilities for the selected BESSD, including the design, development, and commissioning of a BESS that can provide energy storage services, specifically for charging and discharging electricity as per the demands of UPPCL. A notable feature of the tender is the flexibility granted to the BESSD in terms of energy sourcing; the BESS can be charged using any energy source, without the necessity for the developer to own the source. UPPCL will retain oversight of the charging and discharging operations for the contracted capacity, ensuring operational control.
A Battery Energy Storage Purchase Agreement (BESPA) will be executed between UPPCL and the selected BESSD for 12 years, with provisions for the transfer of the project to UPPCL upon the expiration of the BESPA term. This transfer will be conducted on an "as is where is" basis, with the system required to be in working condition and meeting the predefined energy throughput criteria as stipulated in the BESPA.
The BESS is to be connected at specific points within the state's electrical grid: a 132 kV Bay at the 132 kV Substation in Hasayan (Hathras), capable of handling 100 MW, and a 220 kV Bay at the 765 kV Substation in Dahi Chowki (Unnao), capable of accommodating 200 MW. For these installations, a total of 32,000 square meters of land will be made available on a lease or right-to-use basis, facilitated by UPPCL in coordination with the Uttar Pradesh Power Transmission Corporation Limited (UPPTCL).
To incentivize participation, the tender offers a substantial capital state subsidy of ₹2.50 crore per MW.
Technical specifications and financial commitments are detailed within the tender. Bidders must submit a minimum bid capacity of 50 MW, ensuring a minimum system availability of 95% annually. The BESS must maintain a round-trip efficiency (RtE) of 85%, with a permissible capacity degradation of up to 2.5% annually. The project is to be completed within 18 months from the execution of the BESPA.
Financial requirements for participation include a tender document and processing fee totaling ₹1.25 lakh + GST, an Earnest Money Deposit (EMD) of ₹7.40 lakh per MW, and a Performance Bank Guarantee of ₹18.50 lakh per MW per project.
The earlier BESS tender floated by UPPCL for 40 MWh was cancelled at that time even after auction.
This tender marks a significant step forward in UPPCL’s efforts to modernize and stabilize the state’s power grid by integrating advanced energy storage solutions. The implementation of this BESS will not only enhance grid reliability but also support Uttar Pradesh’s broader energy transition goals.
