Yes, but why would anyone charge at peak time? The whole point of Time-of-Day use and rates is to discourage folks from putting extra demand on the grid during the worst times of the day. Tell us what your off-peak rates are? At your peak rates, you might as well Supercharge, it would be faster and cheaper even if you didn't get FUSC.
If your local utility provider in California hasn't already switched to TOD billing and you're still on the old tier system, then look into solar power payment plans or lease. It will cost zero out of pocket and the companies will take care of the maintenance. The solar system is sized based on your 12-month average use so that it helps lower you back into tier 1 or, at worst, tier 2 rates. That provides a huge savings.
