Grand opening is two words, so they would only both be capitalized if they were the title of something.
That is the correct spelling, "grand re-opening." It is only occasionally hyphenated re-opening.
Grand opening is a term used when a business, public office, or private association announces the official opening of a new location. The grand opening is more of a celebration even rather than the first day of opening their doors to customers.
