UPPCL Invites Bids for 300 MW/1,200 MWh Standalone Battery Energy Storage System in Uttar Pradesh

The Uttar Pradesh Power Corporation Limited (UPPCL) has issued a Request for Selection (RfS) document for setting up a 300 MW/1200 MWh standalone Battery Energy Storage System (BESS) in Uttar Pradesh. This project will be established under a “BOOT” (Build, Own, Operate, Transfer) model, and the bidding process will be conducted through e-Tender and e-Reverse Auction.

Developers interested in this project need to submit an Earnest Money Deposit (EMD) of ₹7,40,000 per MW in the form of a bank guarantee. Additionally, a Performance Bank Guarantee (PBG) of ₹18,50,000 per MW per project will be required.

The goal is to select Battery Energy Storage System Developers (BESSD) to set up a 1,200 MWh (300 MW x 4 hours) BESS at designated load centers in Uttar Pradesh. These systems will be used on demand, based on a tariff-based competitive bidding process. The selected developers will enter into a Battery Energy Storage Purchase Agreement (BESPA) with UPPCL, adhering to the terms and conditions outlined in the RfS and BESPA.

With advancements in technology, renewable energy has become a cost-effective solution for meeting energy needs. However, integrating more renewable energy can create challenges due to its variable nature and supply-demand mismatches. To address these issues, integrating Energy Storage Systems (ESS) is crucial. The Central Electricity Authority (CEA) has highlighted that Pumped Hydro Storage Systems and Battery Energy Storage Systems are viable options for providing necessary storage capacity. The CEA study projects a need for a battery storage capacity of 8,680 MW/34720 MWh by 2027-28, in addition to 7,446 MW of Pumped Hydro Storage.

UPPCL aims to use energy storage systems on an “on-demand” basis during peak and off-peak hours. Proposals are invited for setting up a 1,200 MWh BESS, which will involve a contract capacity of 300 MW/1,200 MWh. Bidders can offer capacities in multiples of 50 MW, from a minimum of 50 MW to a maximum of 300 MW. The project capacity will be located near an existing substation in the intra-state network. UPPCL will facilitate land allocation for the project on a lease or right-to-use basis, managed by UPPTCL.

The selected bidder will be allowed to choose a project location from the options provided after the e-Reverse Auction. The Contracted Capacity will be 300 MW/1,200 MWh, and UPPCL will schedule charging of the BESS to match the desired discharge amount, accounting for energy losses during conversion. For example, for a 200 MW/800 MWh capacity, assuming a Round-Trip Efficiency (RtE) of 95%, UPPCL will supply 842.11 MWh of charging energy to achieve an 800 MWh discharge. The minimum energy scheduled for discharge will meet or exceed the minimum dispatchable energy capacity specified in the RfS.
