City of Vaughan Service Area Town of Aurora Service Area Town of Markham Service Area Town of Richmond Hill Service Area Nothing contained in this COS or in any contract for the supply of electricity by PowerStream shall prejudice or affect any rights, privileges, or powers vested in PowerStream by law under any Act of the Legislature of Ontario or the Parliament of Canada, or any regulations there under. 1.1.1 Distribution Overview PowerStream distributes electrical energy through its three phase primary distribution systems and forty-four (44) kilovolt (kV) sub transmission system at nominal operating voltages of forty-four (44) kV, twenty seven point six (27.6) kV, thirteen point eight (13.8) kV, eight point thirty-two (8.32) kV and four point sixteen (4.16) kV depending on the proximity of the Customer’s property to the nearest distribution facility, the geographic location of the property and the capacity required by the Customer. Not all voltage levels are available throughout the PowerStream service area. On the forty-four (44) kV system PowerStream services directly multiple municipal sub stations and multiple Customer owned substations. The municipal sub stations transform the forty-four (44) kV sub transmission voltage to our distribution voltages of our point sixteen (4.16) kV, eight point thirty-two (8.32) kV, thirteen point eight (13.8) kV and twenty seven point six (27.6) kV. Feeders are typically arranged to run radial out from transformer stations owned by PowerStream and Hydro One Networks Inc. Open points exist between feeders and this determines the feeder geographical coverage. These feeders directly supply pole mounted, pad mounted or vault type distribution transformers that reduce the operating voltage to Customer levels. END OF SECTION PAGE 2 OF 2
