ACME Solar Holdings Ltd has signed a Power Procurement Agreement (PPA) with the Solar Energy Corporation of India (SECI) for 300 MW of assured peak power supply, backed by 1,200 MWh of energy storage. The agreement was signed through its subsidiary, ACME Greentech Twenty Pvt Ltd, under SECI’s Firm and Dispatchable Renewable Energy (FDRE-IX) tranche at a tariff of ₹6 per unit. The agreement became effective on October 6, 2026.
The project is designed to supply reliable renewable electricity during evening and night-time peak demand periods, when solar power generation is limited. It is expected to support grid stability as India increases the share of renewable energy in its electricity mix.
Under the agreement, ACME Solar will supply 4 MWh of electricity per MW of contracted capacity for four hours daily during non-solar hours. The project will maintain a minimum monthly availability of 90%, ensuring that the contracted power supply is available during the specified periods.
Solar and Battery Storage to Support Peak Power Supply
The project will combine solar power generation with a Battery Energy Storage System (BESS) to meet its supply commitments. It will also use the night-time grid connectivity already available to the company, supporting the delivery of renewable electricity beyond daylight hours.
Firm and Dispatchable Renewable Energy projects are designed to provide power according to specified schedules and availability requirements. By combining renewable generation with battery storage, such projects can help address the variability of solar power and meet demand during peak hours.
ACME Solar’s Contracted Portfolio Reaches 8,370 MW
Following the agreement, ACME Solar’s under-construction portfolio with signed PPAs stands at 4,310 MW, out of a total under-construction contracted capacity of 5,380 MW, according to the company.
ACME Solar has a diversified contracted portfolio of 8,370 MW across solar, battery energy storage, FDRE, hybrid and wind projects. The company has an operational generation capacity of around 3,123 MW, along with 4.96 GWh of operational battery energy storage capacity.
The latest agreement adds to the company’s FDRE portfolio and reflects the growing role of energy storage in supplying renewable power during periods when solar generation is unavailable.
