Extension of timelines for mega power projects extends security validity and delays final certificate submission deadlines. Amendment to Condition No.93 of Notification No.12/2012-Customs increases the prescribed terms by substituting the original shorter time references with longer ones, thereby extending the validity of securities in the form of Fixed Deposit Receipts or Bank Guarantees and extending the period within which provisional mega power projects must furnish the final mega power project certificate. The amendment adjusts only these temporal parameters without altering other eligibility criteria or the types of acceptable securities.
