ACME Solar Secures 300 MW SECI Contract at ₹6/kWh

ACME Solar Holdings has secured 300 MW of contracted capacity under the Solar Energy Corporation of India's latest peak power tender.

The Gurugram-based renewable energy developer emerged as a successful bidder in the e-reverse auction conducted by the Solar Energy Corporation of India (SECI) under the FDRE-IX tender framework. Announced via official stock exchange disclosures in August 2026, the win involves supplying assured peak power backed by battery storage, underlining a critical push toward dispatchable green energy integration across India's interstate transmission network.

Project Parameters and Tariff Structure

Under the terms of the competitive bidding process, ACME Solar secured the 300 MW capacity at a discovered tariff of ₹6.00 per kilowatt-hour (kWh). The firm and dispatchable renewable energy (FDRE) model mandates that developers guarantee power delivery during high-demand intervals. Specifically, the company will supply 1,200 MWh of power daily across a dedicated four-hour peak window. To achieve this, the project integrates advanced generation assets with a 1.2 GWh battery energy storage system (BESS) component, lifting the company's total PPA-signed storage pipeline to approximately 15 GWh.

Execution Readiness and Land Acquisition

Company officials noted that project execution timelines will benefit from a high degree of pre-development preparation. ACME Solar already holds the requisite interstate transmission system (ISTS) connectivity grant and has acquired a major portion of the land parcels required for installation. Securing land and grid access beforehand addresses common bottlenecks that typically delay utility-scale renewable energy infrastructure deployment across the country.

Official Sources and Corporate Disclosures

According to official regulatory filings submitted to the National Stock Exchange of India (NSE) and the Bombay Stock Exchange (BSE), the Letter of Award formalizes ACME Solar's expanding footprint in peak-load management tenders. Supplementary market updates published via the Ministry of New and Renewable Energy (MNRE) highlight that firm renewable contracts are central to stabilizing grid frequency amid rising national electricity demand.

"According to officials, integrating battery storage with utility-scale solar projects ensures reliable round-the-clock power delivery, matching discom requirements during critical peak-demand hours."

Practical Implications for Energy Markets and Investors

For power distribution companies and industrial consumers, assured peak power supply reduces reliance on fossil-fuel peaking stations during high-demand surges. For institutional investors, expanding battery storage pipelines reinforces ACME Solar's competitive positioning in complex, high-value renewable tenders that demand guaranteed delivery schedules.
