The initial budget for the aid amounts to 660 million euros, however, the initial amount is expected to be increased to 1,320 million euros in the total program.

The autonomous communities will be able to use the budget throughout the national territory until 2023. In addition, they will have to commit 80% of the initial budget during the first year or they must reimburse 50% of what has been committed within 15 months from the publication in the BOE of the Royal Decree.
