Rejigging the systemIn addition to the damage at the Merivale station, 90 hydro poles had fallen, pulling wires down with them. High-voltage power comes into the Hydro One station, gets transformed into lower-voltage power, and goes out through multiple wires to about 20 Hydro Ottawa substations, which in turn feed power into communities and, eventually, into every single home in Ottawa. If the rest of the city was going to get power, the brains at Hydro One were going to have to build a different kind of bridge between the Hydro One and Hydro Ottawa networks. 3rd time's the charmBy Sunday morning, Hydro One thought they could do it and told Hydro Ottawa to expect a power-up around noon. On Saturday morning, Hydro Ottawa CEO Bryce Conrad was warning of a 'multi-day' power outage lasting into the week.
