Solar Energy Corporation of India (SECI) has awarded tender contracts for four Firm and Dispatchable Renewable Energy (FDRE) projects totaling 1.2 GW of power and 4.8 GWh of storage capacity in India’s Tranche VII auction. This was after conducting a competitive e-reverse auction in October 2025. The winning bidders – Adyant Enersol, Serentica Renewables India, AMPIN Energy Utility Nine, and ACME Solar Holdings – secured capacity at tariff levels clustered near ₹6.27–6.28 per kWh. Under the FDRE terms, developers must integrate solar generation with co-located battery energy storage systems (BESS). They also ought to ensure a daily supply of 4 MWh per MW for a four-hour peak period. Additionally, availability minimums of 70% monthly and 85% annually, full responsibility for land, statutory clearances, grid connectivity, and transmission costs also fall in the developers’ field.

The Four Dispatchable Renewable Projects Awarded in India’s FDRE Tranche VII Auction

1. Adyant Enersol (Datta Infra) Solar-BESS Project

Project Overview

Capacity: 100 MW

Supply: 400 MWh

Tariff: ₹6.27/kWh which was the lowest-priced bid.

Technology: Solar PV plus BESS

Contractor Role

Engineering, Procurement and Construction (EPC): Adyant Enersol is responsible for full Build-Own-Operate (BOO) delivery, including solar array installation, BESS procurement and integration, and system commissioning.

Land and Statutory Approvals: Developer will secure land, environmental and statutory clearances, and grid connectivity with interstate transmission system.

Peak Power Delivery: Will supply 4 MWh per MW daily over four specified peak hours with more than 70% monthly and more than 85% availability annually.

Supply Start Deadline: Within 24 months of PPA signing.

Adyant Enersol will build and operate a solar-plus-storage plant focused on peak evening supply. As the lowest-tariff bidder among the FDRE Tranche VII auction projects, this installation signals strong cost competitiveness in India’s dispatchable renewables portfolio.

2. Serentica Renewables India Solar PV-BESS Installation

Project Overview

Capacity: 600 MW

Supply: 2,400 MWh

Tariff: ₹6.28/kWh

Contractor Role

EPC: Serentica is responsible for EPC of solar and BESS infrastructure.

Serentica Renewables will deliver the largest single allocation of India’s FDRE Tranche VII auction projects.

3. AMPIN Energy Utility Nine

Project Overview

Capacity: 199 MW with

Supply: 796 MWh

Tariff: ₹6.28/kWh

Contractor Role

EPC: AMPIN is responsible for EPC.

Peak Supply: Must deliver 4 MWh per MW over four peak hours daily with stipulated performance metrics.

AMPIN Energy Utility Nine, part of AMPIN Energy Transition, will bring its cross-state portfolio of solar, wind, hybrid and storage assets to the FDRE framework. The developer has an existing footprint across more than 20 Indian states.

4. ACME Solar Holdings Solar and Battery Storage Project

Project Overview

Capacity: 301 MW with 1,204 MWh assured daily.

Tariff: ₹6.28/kWh

Contractor Role

EPC: ACME Solar will lead EPC delivery, BESS procurement and integration.

Regulation and Transmission: ACME is responsible at its own cost.

Peak Power Delivery: Must meet the SECI requirement of 4 MWh per MW for four peak hours daily.

ACME Solar clinched 301 MW under the bucket-filling allocation mechanism. The project adds to its diversified portfolio that now exceeds 8 GW of contracted capacity across solar, wind, storage, hybrid, FDRE and round-the-clock installations.

Sector Impact and Outlook on India’s FDRE Tranche VII Auction Projects

India’s FDRE Tranche VII auction projects are expected to start supplying assured peak energy within 24 months of Power Purchase Agreement (PPA) signing. This aligns with government goals to enhance grid reliability while increasing solar and storage integration. The auction’s competitive tariffs that were tightly clustered near ₹6.27-6.28/kWh also point toward the strengthening economics for firm renewables across the Indian supply chain.
