Power Grid Corporation of India Limited (POWERGRID) has invited bids for the development of a large Battery Energy Storage System (BESS) project in Punjab, marking another step toward strengthening India’s renewable energy infrastructure and improving grid reliability. The tender is issued under reference number CC/T/W-MISC/DOM/A00/26/03168 and forms part of a broader national effort to integrate renewable energy sources such as solar and wind into the power grid more efficiently.
The project, titled Punjab-BESS-02, involves the installation of a 100 MW/200 MWh standalone battery energy storage facility in Patiala, Punjab. This installation is part of a larger program to develop 500 MW/1000 MWh of energy storage capacity across the state through the Tariff-Based Competitive Bidding (TBCB) route. Battery energy storage systems play a crucial role in modern power systems by storing electricity when generation is high and supplying it back to the grid when demand increases.
The upcoming storage facility in Patiala will help manage fluctuations in renewable power generation. Solar and wind energy production often varies depending on weather conditions, which can create challenges for maintaining a stable electricity supply. By storing excess power during periods of high generation and releasing it during peak demand hours, the BESS will help reduce pressure on conventional thermal power plants and improve overall grid stability.
The project has been categorized under “Power/Energy Projects” and falls under the “Works” contract category. Once operational, the standalone battery system will function as a large electricity reservoir for the grid, helping maintain a balance between power supply and demand in the region.
POWERGRID has outlined a clear timeline for the tender process. The sale of tender documents began on March 3, 2026, at 5:00 PM and will continue until March 16, 2026, at 11:55 PM. Interested bidders must submit their soft copy bids by March 18, 2026, at 11:00 AM. The technical bids will be opened on the same day at 11:30 AM.
The tender includes certain financial requirements for participating companies. A non-refundable tender fee of ₹25,000 is required to access the tender documents. Although the summary indicates an Earnest Money Deposit (EMD) of ₹0 at the initial stage, bidders will be required to provide bid security as detailed in the complete tender documents available on the PRANIT portal. Additionally, a Performance Bank Guarantee (PBG) will be required to ensure the long-term operation and reliability of the storage system.
The procurement process is being managed through POWERGRID’s PRANIT e-tendering platform under RFX Number 5002005154. The tender process is being overseen by Sandeep Panwar, Chief Manager in the Contract Service Department at POWERGRID’s Gurgaon office.
The planned battery storage project is expected to support Punjab’s growing renewable energy capacity while improving grid flexibility and ensuring a more reliable electricity supply in the state.
