As others have said you have to be in an area with cheap power. There are 3 counties in central WA that have their own dams, and thus very cheap power. (Chelan, Douglas, Grant)
For example :
Electric rates
Beginning Jan. 1, 2012, Chelan County PUD moved to a flat residential rate for electricity of just 2.7 cents per kilowatt hour. That's one of the lowest rates in the nation. This new approach to rates will lower bills for most residential customers. Read more about the new rate structure.
Residential monthly energy charge per kWh:
2.7 centsMonthly basic charge: $7.70
Unfortunately Benton County is just 1 county too far south and my local PUD charges $0.06/KWH
