Network Operating

Our new state-of-the-art grid control centre in Barrie puts the most sophisticated technology in the hands of Hydro One's staff so they can better manage our network. By gathering together employees from 13 different operating centres under one roof, Hydro One has reduced costs and improved our operating performance. We've also introduced new Network Management System software, improved backup facilities, tightened security and bettered our crisis management capabilities.

For our customers who have regular contact with our Network Operating group, you can access your customer-specific information on our Network Operating website (password protected).

Power Quality Inquiries

Power Quality (PQ) refers to characteristics of electricity at a given point on the delivery path, as it relates to the compatibility between the electricity supplied on a network and the loads connected to that network. In short, everything in between "power is off" and "power is on" relates to Power Quality. As the transmission system is interconnected, in some cases, one customer's equipment can adversely affect the quality of electrical supply to another customer. For example, large motors, arc furnaces, a large number of non-linear loads such as variable speed drives, or power factor correction capacitors, can all contribute to power quality disturbances. It is also possible that normal switching on Hydro One's network equipment may adversely affect your equipment or operations.

Hydro One is responding to our customers' PQ issues with a Power Quality Inquiry Response Process. For more PQ event definitions, visit our Power Quality section.
