Financial and Security Stipulations
The financial parameters governing participation and performance are summarized below:
| Parameter | Financial Requirement |
| Tender Processing Fee | INR 40,000 + GST |
| Earnest Money Deposit (EMD) | INR 7,500 per MW per month (Total: INR 18 Lakhs) |
| Contract Performance Guarantee (CPG) | INR 50,000 per MW per month (Total: INR 1.2 Crores) |
| SECI Trading Margin* | INR 0.07/kWh |
*The SECI trading margin is an administrative fee charged to the buying entity (TSECL) and does not constitute a bidder-side requirement for submission or fulfillment.
The EMD must be submitted as a Bank Guarantee (BG) or electronic Bank Guarantee (e-BG). The successful bidder is required to provide the CPG within seven days of selection to maintain contractual compliance.
Operational and Deviation Clauses
The tender establishes specific protocols for transmission costs and supply variances.
Transmission Charges
Responsibility for transmission-related costs is divided at the delivery point. The bidder bears all open access charges and transmission costs required to reach the delivery point (Tripura State Periphery). TSECL is responsible for all costs beyond this point, including transmission withdrawal charges (T-GNA), State Transmission Utility (STU) charges, losses, scheduling charges, and State Load Despatch Centre (SLDC) application fees.
Deviation Settlement
A deviation settlement mechanism manages variances between scheduled energy and actual delivery on a monthly basis. A deviation limit of 15% of the contracted energy is permitted for both the buyer and the seller. If actual scheduling deviates from the contracted energy by more than 15%, the defaulting party must pay compensation to the non-defaulting party. This compensation is calculated at 20% of the tariff for the quantum of the shortfall that exceeds the 15% limit.
Bidding Schedule and Technical Evaluation
The following deadlines apply to the procurement process:
- Online Bid Submission End Date: May 4, 2026 (18:00 hrs)
- Offline Bid Submission End Date: May 6, 2026 (18:00 hrs)
- Technical Bid Opening: May 7, 2026 (10:00 hrs)
The selection process follows a single-stage, two-envelope competitive bidding method, comprising a techno-commercial evaluation (First Envelope) and an Initial Price Offer (Second Envelope).

The e-RA features an initial duration of 120 minutes, with 10-minute auto-extensions triggered by any lower bids received in the final 10 minutes. The minimum bid decrement is set at INR 0.01.
