You can get those here, but its normally cheaper overnight when I am not using anything and more expensive during the day when I am. There isn’t much I could load shift so it probably isn’t worth it.

At some point looking to get solar and maybe a battery, the battery depends on the export rate as if only terrible rates are available it makes more sense to get a battery and possibly even cut off from the grid entirely as you still have a standing charge here even if you use nothing or only send energy back to the grid.
