This is a variable-rate plan: the provider can reset its rate every month, with no formula and no cap, so projecting today's rate across a year isn't a real forecast the way it is for a fixed-rate plan. Kilowise doesn't compute an estimated annual cost for that reason. PowerToChoose's own disclosed price at standard usage tiers is below, current as of the last data refresh.
