Notwithstanding its natural advantages due to economies of scale and service territory density, Toronto Hydro currently charges 28% more for distribution service than the average of the distribution rates charged by the province’s other large urban distributors. Toronto Hydro’s record on rates charged to small and medium-sized business is much worse.
Attached are surveys of the core distribution rates of each utility for residential customers as well as for small businesses with demand less than 50 kW and medium-sized businesses with demand of 1 MW. The methodology for determining the core distribution rates of each utility is consistent with the corrected version of the analysis presented in Part 113 of this series. Excluded from these surveys are charges included in distribution rates but recovered on behalf of entities other than Toronto Hydro, such as contributions to the “Smart Metering entity”. Also excluded are temporary charges such as rate riders for Global Adjustment deferral account clearance, stranded meter assets recovery, other deferral and variance account clearance, tax adjustments, foregone revenue, CGAAP/CWIP differential, Smart Grid funding adder, and the Ontario Clean Air Benefit. The rates for each utility are taken from the applicable rate order of the OEB.
What the surveys show is that small businesses with demand less than 50 kW served by Toronto Hydro pay core distribution rates 57% more than the arithmetic average of rates for identical customers served by the next nine largest urban power distributors in Ontario. Medium-sized businesses with demand of 1 MW served by Toronto Hydro pay rates 62% more than the average of identical customers served by Toronto Hydro’s peers.
