The company’s winning bid stood at Rs 4.35 per unit.

The bid is aimed at the procurement of power by the Indian Railways, which requires a consistent power profile throughout the day due to its unique load requirements. Under the tender, the Railways will enter into a direct Power Purchase Agreement (PPA) with the winning bidders, eliminating intermediaries.

The tariff discovered in the auction highlights the competitiveness of renewable energy in providing high CUF power around the clock through co-located solar, wind, and battery solutions at competitive prices.

As per the tender, ACME Solar will supply renewable energy complemented with dispatchable sources and/or Energy Storage Systems (ESS) from ISTS-connected projects to ensure firm, round-the-clock clean power. The project requires a minimum annual availability of 75% for the first three years from commissioning, increasing to 85% thereafter. Achieving this will involve optimal deployment of solar, battery, and complementary wind power.

ACME Solar is expected to commission the project within 30 months of signing the PPA, leveraging available land and connectivity within its existing portfolio.
