Boro,
As someone who deals with mineral management situations daily, (oil/natural gas/coal), be cautious and realistic. Remember you are negotiating with a power company, if you become too much of an @$$ they can and will use their right of Eminent domain.
Eminent domain, an action of the state to seize a citizen's private property, expropriate property, or seize a citizen's rights in property with due monetary compensation, but without the owner's consent. The property is taken either for government use or by delegation to third parties who will devote it to public or civic use or, in some cases, economic development. The most common uses of property taken by eminent domain are for public utilities, highways, and railroads.
