Power Grid Corporation of India Limited (POWERGRID) has invited bids for a major intra-state transmission project in Maharashtra aimed at strengthening the regional power grid. The project will be implemented through the Tariff-Based Competitive Bidding (TBCB) route and focuses on building high-voltage transmission infrastructure to support growing electricity demand and renewable energy integration in the state.
The tender, issued under reference number CC/T/W-AIS/DOM/A00/26/03327, is titled Package SS 151T. It mainly involves the construction of a new 765 kV Air Insulated Substation (AIS) along with expansion work at several other substations in the region. The key component of the project is the development of a 765/400/220 kV AIS substation at Balsane in Dhule district. This new facility is expected to play an important role in strengthening transmission capacity and improving power flow in northern Maharashtra.
Along with the construction of the Balsane substation, the selected contractor will also carry out extension work at three other substations. These include the proposed 400 kV Malegaon substation, the existing 220 kV Shivajinagar substation, and the 220 kV Vikharan substation connected to a MAHAGENCO solar facility. The expansion of these substations is expected to support better power evacuation from renewable energy projects and improve grid reliability in the Dhule and Malegaon regions.
The project is considered an important step in Maharashtra’s broader energy infrastructure strategy. With solar power capacity increasing in the state, new transmission infrastructure is required to ensure that renewable electricity can be efficiently transmitted to demand centers. Strengthening the grid will also help maintain stability and reduce congestion in the regional network.
According to the tender notice, the project falls under the open category for works in the power and energy sector. The preliminary notification lists the estimated tender value as zero, which generally means that the final cost will be determined through the competitive bidding process. Interested bidders are required to pay a non-refundable tender fee of ₹25,000.
The notice also mentions that the Earnest Money Deposit (EMD) is listed as zero in the summary details. However, as per typical POWERGRID project procedures, the selected bidder will likely be required to provide a Performance Bank Guarantee after the contract is awarded. This performance security usually ranges between 3 percent and 10 percent of the contract value to ensure timely completion of the project.
The bidding process will be conducted online through the PRANIT portal under RFX number 5002005158. Document sale began on March 5, 2026, and will continue until March 14, 2026. Bidders must submit their technical and commercial proposals by March 16, 2026, at 11:00 AM, while the bids are scheduled to be opened at 11:30 AM on the same day.
The tender process is being managed by Umesh Kumar Yadav, Manager at POWERGRID’s corporate office in Gurugram, Haryana. With the TBCB route encouraging competitive pricing and technical capability, the project is expected to attract strong participation from infrastructure companies experienced in extra-high voltage substation development.
