The Tamil Nadu Green Energy Corporation Limited has invited bids to develop a 15 MW grid-connected solar power project along with a 15 MW/45 MWh battery energy storage system. The tender is an open bid under a two-part system and will also include an e-reverse auction. The request for selection was issued on November 19, 2025, in the evening, and bidders are required to follow all the terms and conditions mentioned in the tender document without asking for any changes.

A pre-bid meeting has been planned for November 27, 2025, at 11:30 in the morning at the TANTRANSCO building in Chennai. Interested bidders can send their questions by email until December 4, 2025, and the corporation expects to publish its replies by December 8, 2025. These steps are meant to ensure that all participants have access to the same information before preparing their bids. The financial requirements for taking part in this tender are significant, especially the bid security amount of one crore rupees, which can be paid online or through a bank guarantee. Once a bidder is selected and receives the letter of award, they must also provide a performance bank guarantee of five crore rupees within 30 days.

The online submission window for bids will open on December 10, 2025, in the late afternoon. Bidders will have time until December 26, 2025, at 2:00 PM to upload their documents. The techno-commercial bids will be opened the next day on December 27, 2025, at 3:00 PM. The date and time for the e-reverse auction will be communicated individually to the bidders who qualify after the techno-commercial evaluation. This process is designed to ensure fair competition and transparent selection.
