Just to clarify I am in WA.
Interesting FUD, happens my power company is aware I was mining and didn't AND STILL DOES NOT CARE as long as I keep the bill paid up.
I am also in Washington State.
I suspect there is something else going on here the OP isn't talking about.
Yes companies do usually like to sell their goods and are happy when you purchase more. Something is up, again I am betting they are worried it was a grow operation or something similar.
