It depends.

Are you on a mountain top and terrain is flat?

Than 15W might do it with reasonable antenna.

For solid coverage that a professional station goes for at least 200W would be recommended, but many would use 1KW.

Antenna? I would consider two dipoles or an exterminatorII as a start.

I'd go with 250W:

Depending on how it works I'd consider upgrading antenna system later.

Don't forget to add stereo option.
