In my area, summer "peak hours" often make up half my electricity usage. The off-peak hours are the other half. The price at peak times is more than double the flat rate, but only 30% cheaper for off-peak. I'm already reducing my energy use as much as is comfortable, if I want to maintain that I'd be paying more money than the flat rate. The scheme only saves energy if its not optional.
