** There is a Power Purchase Agreement (PPA) in place with Punjab Discom for our Biomass Power Generation business. The average billing for the preceding two fiscal years has been ₹80 crore per year. The Hon'ble Punjab State Electricity Regulatory Commission has passed an interim Order revising the tariff of Malwa Power Private Limited for a fixed tariff of Rs. 3.50 per unit as the PPA has expired on 26.04.2025, however, this rate will be revised shortly by a final Order. For ease of understanding, we have considered the order inflow and execution amount to be the same for this period.
