ACME Solar Holdings, through its fully owned subsidiaries, has secured battery energy storage purchase agreements (BESPA) with NHPC for a combined capacity of 275 MW/550 MWh across two standalone battery energy storage projects in Andhra Pradesh. The company clinched 50 MW/100 MWh at a rate of INR 2,10,000 per MW per month, and 225 MW/450 MWh at INR 2,22,000 per MW per month, following an e-reverse auction on June 24, 2025.
The projects are eligible for Viability Gap Funding (VGF) under the Government of India’s initiative, which offers financial assistance of INR 27 lakh per MWh or 30% of the total project cost, whichever is lower. The Letter of Award (LOA) for these projects was formally issued on July 8, 2025. ACME Solar noted that the swift transition from the LOA to signing the BESPA was facilitated by the prior identification of Andhra Pradesh as the project site.
Since the land and evacuation infrastructure will be provided by the customer, the company anticipates that the project execution will proceed without delays. These energy storage systems are slated for completion within 18 months from the signing of the BESPA.
