ACME Solar Holdings Limited (ACME Solar) has emerged as the winning bidder for 130 MW under the e-Reverse auction conducted by REMC Limited’s (REMCL) 1000 MW Round-the-Clock (RTC) Renewable Energy project tender.
The company’s winning bid was Rs 4.35 per unit. The Letter of Award (LOA) is expected to be awarded within the timelines prescribed in the tender document.
This bid is for the procurement of power by the end user, i.e., Indian Railways, which requires a consistent power profile throughout the day due to its unique load requirements. The Railways will enter into a direct Power Purchase Agreement (PPA) with the winning bidders without any intermediary.
This bid and tariff demonstrates the competitiveness of renewable energy to provide high CUF power throughout the day by co-locating Solar/wind and battery at the most competitive price.
As part of this winning bid, ACME Solar will be required to 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, in line with the obligations laid out in the tender document. It mandates a minimum annual availability of 75% for the first three contractual years from commissioning and 85% thereafter. This will necessitate a multiplier of contracted capacity of solar and battery installation with an optimal amount of complementary wind power as and when required.
ACME Solar will commission this project within 30 months of signing the PPA. This commissioning will be expedited by the availability of land and connectivity within the ACME portfolio.
