Nope, the most we've ever paid for powershop power was 23 cents per unit, the least 9 cents. We've gone from having over $500 bills in winter, to this last one the biggest we had was just under $300. That's one heck of a difference for doing nothing different but change power companies.
If you don't buy the power yourself, they automatically buy it at the lowest normal price (that isn't the best deal tho, that's when it's on special which it always is).
Hope that helps .
