Do I need to provide IDwhen I vote by absentee ballot in Delaware

You do not need to include ID if you've already voted in Delaware at least once. If you are a first-time Delaware voter, and you registered by mail, and you did NOT include a copy of your ID with your voter registration form, then you MUST include a copy with your absentee ballot application. Acceptable forms of ID include: a COPY of a current and valid photo identification OR a COPY of a current utility bill, bank statement, government check, paycheck or other government document that shows your name and Delaware address.
