Hydro One replaces over 11,000 wood poles to maintain system reliability

TORONTO, June 11, 2013 /CNW/ - Hydro One crews across the province are replacing 11,000 poles this year across its 120,000 kilometer distribution system. The $82 million investment is imperative to maintaining system reliability and public safety.

"This investment is part of an ongoing program to continually assess the condition of our power system and make significant upgrades to improve overall reliability," said Mitch Ouellette, Director, Distribution Asset Management, Hydro One. "This work is a reflection of Hydro One's proactive approach to monitoring and improving our distribution system to deliver value to our customers."

The poles slated for replacement were identified through Hydro One's pole testing and assessment program. All power lines, poles and related equipment owned and operated by Hydro One are inspected periodically to identify any potential problems so that they can be corrected without causing an unplanned power interruption. Over time, pole quality can be affected by decay and rot, insect and rodent damage or mechanical impact. Wood poles that are in need of replacement are more susceptible to damage from strong winds and severe storms.

Wood poles that need to be replaced during an unplanned outage as a result of a failure can take substantially more time  to replace and can leave customers in the dark when they most need to use electricity. With 1.7 million wood poles in Hydro One's distribution system across Ontario, more than 340,000 will need to be replaced in the next 10 years. The average life span of a wood pole is approximately 62 years.

Hydro One delivers electricity safely, reliably and responsibly to homes and businesses across the province of Ontario and owns and operates Ontario's 29,000 km high-voltage transmission network that delivers electricity to large industrial customers and municipal utilities, and a 121,000 km low-voltage distribution system that serves about 1.3 million end-use customers and smaller municipal utilities in the province. Hydro One is wholly owned by the Province of Ontario.
