Time-of-use rates (TOU) paid by residential and small business customers include the global adjustment charge. The Ontario Energy Board reviews time-of-use rates every six months. These regulated rates are based on projections of consumption−how much power consumers will use−combined with the estimated cost of power over that time period. If the previous projection was either too high or low, that will also be accounted for in the new rates.
New rates take effect May 1 and November 1 of each calendar year.
