It was later on amended on 19.11.2011. The PPA was duly approved by the Commission vide order dated 10.06.2009 in petition no.610/2009.

6. The Power Purchase Agreement dated 12.11.2006 was executed during the period when UPERC Tariff Regulations, 2004 were in force. Regulation 26 of these regulations is with regards to the LPSC and provided as under: -

“26. Late Payment Surcharge: In case the payment of bills of capacity charges and energy charges by the beneficiary (ies) is delayed beyond a period of 1 month from the date of billing, a late payment surcharge at the rate of 1.25% per month shall be levied by the generating company.”

7. As per Article 1 of the PPA, due date shall mean the 30^th day after the receipt of invoice in relation to any amount payable by UPPCL. Section 12.17 under Article 12 of the PPA is in respect of the rebates and late payment charges. The same is extracted hereinbelow: -

“Section 12.17 Rebates, Late Charges

(a) For payment of bills of Fixed Charges and Variable Charges through a Letter of Credit on presentation, a rebate of 2% shall be allowed. If the payments are made by a mode other than through the Letter of Credit, but within a period of one month of presentation of bills by ROSA, the rebate of 1% shall be allowed.
