Gujarat Urja Vikas Nigam Ltd (GUVNL) has issued a new tender for Phase IV of its Battery Energy Storage System (BESS) projects, reflecting the growing momentum in India’s energy storage sector. This follows the success of previous tenders, where Phase II and Phase III saw the award of projects with capacities of 250 MW/500 MWh each, achieved at a competitive rate of ₹3.72 lakh/MW/month. The latest tender aims to harness the potential of BESS technology to further strengthen grid stability in Gujarat.
Key Details of the Phase IV Tender
Project Scope: The tender invites bids for the development of 400 MW/800 MWh standalone BESS projects, with an additional Green Shoe Option for another 400 MW/800 MWh. These systems will be developed under a Build-Own-Operate (BOO) model, with the successful bidders assuming responsibility for the entire lifecycle of the projects.
On-Demand Energy Storage: GUVNL plans to utilize these BESS installations on an “On-Demand” basis, tailored to meet the dynamic energy requirements of State DISCOMs during both peak and off-peak hours. This strategic approach aims to optimize energy storage usage and ensure reliable grid performance.
Battery Energy Storage Purchase Agreement (BESPA): The successful bidders will enter into a 12-year BESPA with GUVNL, under which they will provide energy storage services through a competitive tariff-based reverse auction (eRA) process. This agreement will outline the terms for charging and discharging the BESS, aligning with GUVNL’s operational needs.
Infrastructure and Interconnection: The BESS developers (BESSD) will be responsible for the design, construction, and interconnection of the BESS with the Gujarat State Transmission Utility (GETCO) network. This includes all infrastructure development up to the interconnection point and ensuring compliance with regulatory standards.
Green Shoe Option: To accommodate future expansion, GUVNL has included a Green Shoe Option, allowing for additional capacity. The system will be charged using power drawn from the GETCO network, and energy injection will be managed in accordance with dispatch instructions from the State Load Dispatch Centre (SLDC), in consultation with GUVNL.
Transmission and Maintenance Responsibilities: The BESSD will maintain the transmission system up to the interconnection point, covering all associated costs. Beyond this point, GUVNL will bear transmission charges and losses as per the prevailing regulations.
Operational Limits: The tender specifies a maximum cooling time of 1 hour between charge and discharge cycles, with a recovery time for a full cycle not exceeding 2 hours. The BESS must maintain a minimum system availability of 95% annually and a Round Trip Efficiency (RtE) of 85%.
Project Location and Land Allocation: The project will be strategically located near key substations within the Gujarat Energy Transmission Corporation (GETCO) network, each with specific capacity allocations:
400 kV Pachchham GIS: Up to 200 MW
220 kV Dholera GIS: Up to 250 MW
400 kV Bhachunda GIS: Up to 180 MW
220 kV Savdasna Muvada (Lunawada) AIS: Up to 50 MW
220 kV Tharad AIS: Up to 100 MW
220 kV Sadla AIS: Up to 100 MW
220 kV Radhanpur AIS: Up to 50 MW
220 kV Khanpur AIS: Up to 100 MW
These sites have been selected for their strategic importance in stabilizing the regional grid and optimizing energy distribution. GUVNL will provide a total of 166,931 square meters of land on a right-of-use basis at a nominal lease rate of ₹1 per plot per year. The L1 bidder, identified through the e-Reverse Auction, will have the first right to choose their preferred location among these substations, ensuring flexibility and strategic placement for maximum operational efficiency.
