Some locations have really high prices for electric. Some companies combine the gas and electric into one bill. Our water pump is shared with the neighbor--the combined usage is usually around $65 for the year, which we split. We use LP, so that is a separate bill. For the house (about same sq footage as yours) we run at-about $75-85 a month on the budget plan. To do this we keep the house chilly in the winter, and warm in the summer. We have a contest to see who knuckles under first and turns on the A/C--so far it has been on once for company. Agree with the above posts--talk to a company rep. Your bill sounds really high.
