The Hon’ble Punjab State Electricity Regulatory Commission (PSERC) had passed an interim Order revising the tariff of Malwa Pow er Private Limited for a fixed tariff of Rs. 3.50 per unit as the PPA was expired on 26.04.2025, then the Company had filed the review petition for revision of these tariff rates. Vide PSERC’s Final order dated 27 March 2026, tariff rate for FY 2025 (cid:1)(cid:230)26 was fixed at Rs 5.224/kWh (Rs 0.97 fixed + Rs 4.254 variable) with an annual excalation of 5% on variable cost. Hence the ta riff rate for FY 2026-27 shall be Rs. 5.437 per kWh. As menioned in the Press Release uploaded in NSE & BSE on 01/04/2026, the Compa ny has filed an appeal before the APTEL, New Delhi and challenge the order passed by the PSERC determining the tariff for the plant with a prayer to increase the tariff as per the CERC Regulations. Further, the projected revinue for FY 27 shall be ~ Rs. 47.71 crores which includes Rs. 23.4 crores from the pallete plant. Tariff of DEE Development Engineers Limited (Power Division) were revised to Rs. 5.877 per unit by Hon’ble PSERC vide its order dated 20.08.2025, however, the Company had filed appeal before hon’ble High Court of Punjab & Haryana against the order of Hon’ble PSERC. The Hon(cid:146)ble High Cou rt, vide its order dated 23rd October, 2025, has stayed the operation of the Commission(cid:146)s order. As a result: a) The Company shall continue to supply electricity to PSPCL at the prevailing tariff of (cid:4)_ 7.47 per unit. b) Any recovery claimed by PSPCL on account of tariff differential shall remain withheld until the final disposal of the matter by the Hon(cid:146)ble High Court. The total value of orders executed during the period represents the aggregate amount of invoices raised on customers. However, the revenue recognized under Indian GAAP (Ind AS 115 (cid:150) Revenue from Contracts with Customers) may differ from the invoiced amount, owing to the application of vari ous Incoterms and performance obligations under respective contracts. Consequently, revenue recognition is aligned with the transfer of control of goods or s ervices to the customer, and not merely based on invoicing milestones. Accordingly, the revenue recognized during the reporting period may be lower than the total invo iced value for the same period. # Exchange rates for existing export orders of DEE Thailand considered at 1 THB =2.87705 INR.
