Acme Solar Secures 300 MW Capacity In SECI Peak Tender

ACME Solar Holdings has secured 300 MW at 6 rupees per kWh in SECI's peak power tender, supplying 1,200 MWh over four hours.

Expanding Peak Power Capacity in India

NEW DELHI — ACME Solar Holdings Limited has expanded its footprint in India's grid-connected renewable energy sector by winning 300 MW of capacity in the competitive auction administered by the Solar Energy Corporation of India (SECI). The auction, part of SECI’s Firm and Dispatchable Renewable Energy (FDRE) framework, targets reliable, round-the-clock power management through storage-backed assets.

According to auction results released in August 2026, the tender framework sought to procure a total of 6,000 MWh of peak power capacity from 1,500 MW of interstate transmission system (ISTS)-connected renewable projects. ACME Solar secured its 300 MW allocation—translating to 1,200 MWh of storage-backed supply over a four-hour duration—at a competitive discovery tariff of 6 rupees per kWh, running parallel alongside awards secured by NTPC Renewable Energy and Waaree Energies.

Storage Integration and Grid Reliability

The integration of firm and dispatchable renewable energy (FDRE) represents a pivotal shift in India's clean energy strategy, transitioning from basic intermittent generation to guaranteed peak-hour delivery. By combining utility-scale solar generation with advanced battery energy storage systems (BESS), developers can mitigate the intermittency challenges traditionally associated with photovoltaic power plants.

Industry analysts note that pricing discovered near the 6 rupees per kWh threshold reflects the real cost of incorporating multi-hour storage infrastructure to meet high-demand evening peaks. This project configuration ensures that utilities can maintain grid stability and satisfy mandatory renewable purchase obligations without risking supply deficits during non-solar hours.

Quote Section

"According to officials, the incorporation of storage-backed peak power tenders is essential for ensuring grid resilience and fulfilling long-term clean energy delivery commitments across regional distribution networks."

Why It Matters

For utility providers and industrial consumers, the deployment of 4-hour peak power blocks ensures guaranteed energy availability during high-demand intervals, reducing reliance on fossil-fuel peaking plants. For investors and renewable energy developers, securing long-term PPAs at stable tariffs provides predictable cash flows while validating the commercial viability of large-scale battery storage integration in India.
