Jim Lazar spoke at the Hawaii Power Summit in Honolulu about time-of-use rates, and in particular, moving the current Hawaii commercial rate design from one that rewards a high load factor to one that rewards customers who adjust their loads to better fit a solar-heavy power system. He recommends confining the demand charge to the 5 – 9 PM hours (the “neck” of the duck curve) and converting the flat energy rate to a time-of-use rate lowest during the daytime hours.
