ACME Solar Holdings Ltd (ACME Solar) has announced that the company has been awarded a Letter of Award (LOA) for a 220 MW Solar with Battery Energy Storage System (BESS) project by Rewa Ultra Mega Solar (RUMSL).
The project is part of a 440 MW tender floated by RUMSL for the Morena Solar Park in Madhya Pradesh. The tender was floated under tariff-based competitive guidelines (TBCB) for which an e-reverse auction was conducted in September 2025.
The project requires supplying power with a maximum annual CUF of 35 percent, along with 4 hours of peak supply (2 hours each in the morning and evening) at 95 percent annual availability. Charging energy for the evening peak will be sourced from the solar plant, while energy for the morning peak will be supplied free of cost by the procurer during night hours, ACME Solar stated.
It further added that the land and evacuation infrastructure above 33 kV level would be provided by RUMSL as part of the facilities offered by the solar park developer. Additionally, the project also incorporates the benefit of reduced GST rates already passed through and will be required to adhere only to ALMM List-I.
The project would combine Solar and BESS technologies to meet the supply obligations for the Power Purchase Agreement (PPA) tenor of 25 years. Going forward, PPA would be signed with Madhya Pradesh Power Management Company (MPPMCL) and RUMSL, the company said.
ACME Solar has a diversified portfolio of 8,071 MW spanning solar, wind, storage, FDRE and hybrid solutions and an operational contracted capacity of 2,966 MW and under-construction contracted capacity of 5,105 MW, including about 17 GWh of BESS installation. The under-construction PPA signed portfolio stands at 2,664 MW, the company stated.
