Duty exemption for power project inputs narrowed to specified projects and time-limited eligibility under amended notification. Notification No. 34/2012 amends the prior Central Excise exemption framework by substituting open-ended references to goods 'required for setting up' or 'supplied to' mega/ultra-mega power projects with explicit cross-references to newly inserted List 10 and List 11, enumerating named projects and specific expansion units. Conditions No. 42 and 43 in the Annexure are amended to require certification before a specified cut-off date for eligibility, converting the exemption into a project-specific, time-limited regime and including corrigenda to certain project entries.
