SECI Finalises 4,800 MWh FDRE Auction Results

The Solar Energy Corporation of India Ltd. (SECI) has concluded its latest Firm & Dispatchable Renewable Energy (FDRE) Auction — Tranche VII, awarding contracts for 4,800 MWh of assured peak-power supply from renewable projects paired with storage systems.

Under this auction, SECI sought bids for projects capable of supplying 1,200 MW of clean energy for four hours each day during peak demand hours (evening to morning) by combining renewable energy with energy storage systems (ESS).

Four companies emerged as winners after competitive bidding:

Adyant Enersol (Datta Infra) secured 100 MW with the lowest tariff of ₹6.27 per kWh.
Serentica Renewables India won 600 MW at ₹6.28 per kWh.
AMPIN Energy Transition (operating as AMPIN Energy Utility Nine) was awarded 199 MW at the same tariff.
ACME Solar Holdings was allocated 301 MW using the bucket-filling method at ₹6.28 per kWh.

All tariffs discovered in this auction fell in a tight range between ₹6.27 and ₹6.28 per kWh, indicating a competitive pricing environment for dispatchable renewable power.

The auction was originally floated in October 2025, with specific requirements that developers must supply at least 4 MWh per MW of contracted capacity for any four hours every day. Projects must also meet minimum availability levels — 70 % monthly and 85 % annually — ensuring reliability beyond just solar generation hours.

Under the tender’s terms, winning developers are required to build and integrate renewable generation assets with battery storage, secure grid connectivity, and comply with technical and cybersecurity norms. They may also source up to 5 % of annual renewable energy from green markets or bilateral arrangements to help meet supply obligations.

This auction is seen as part of India’s broader effort to support clean energy capacity that can meet peak power demand reliably, strengthening grid stability while advancing the country’s renewable goals.
