Realizing significant value for both company and customers

David Curtis, Director, Engineering Talent Management at Hydro One talks us through their experience with the Woodhouse Partnership and benefits of refining their asset management practices.
Reduction in ‘trouble calls’ and interruptions to customer service by 21%
Reduced SF6 Gas leaks by 26%
Improved asset analytics to identify the truly badly performing assets
Contract Objectives

“Hydro One has had a long and very productive relationship with the Woodhouse Partnership. Our first encounter occurred when Hydro One was one of the international participants in the revamping of the British Standards Institution’s Publicly Available Specification (BSI PAS) 55 that was issued in 2008. By that time, Hydro One had made the strategic decision to follow Asset Management methodology because of its anticipated efficiencies and productivity improvement. The strong leadership that Woodhouse provided in the revamping of BIS PAS 55 demonstrated to us that they could provide us with astute and experienced guidance in our application of Asset Management within Hydro One.”

“We engaged Woodhouse to provide us with an independent review of the state of Asset Management in Hydro One following the format of BIS PAS 55. This review provided us with a gap analysis between our existing asset management activities and internationally recognized good practices. We have used the results of this review to guide our further development of asset management practice within Hydro One.”

Activity Description

“Subsequent to this review, we engaged Woodhouse to assist the development of our staff, analytic approaches and tools in the further refinement of our asset management practice. There have been many success stories for Hydro One arising from this relationship. As one example, we were having problems with the performance of our SF6 breakers. Breakers are, essentially, large switches that we use to connect and disconnect large generators or loads to the grid. Breakers have an insulating medium that inhibits arcing or flash-over as the breaker makes or breaks the connection to the grid. Arcing can result in damage to equipment and is a safety hazard. With an SF6 breaker, the insulating medium is SF6 or sulphur hexafluoride gas.

“We were having problems with the performance of these breakers and these problems were resulting in interruptions to the delivery of power to our customers. With Woodhouse, we started a review of our asset management strategy with respect to our SF6 breakers and we found that there appeared to be gaps in maintenance and asset management strategy on SF6 breakers.”


Contract Project Outcomes

“We improved our asset analytics to identify the truly badly performing assets, we targeted improved maintenance and refurbishment actions at those assets, and we conducted training programs with the maintainers to address issues in the field. With this asset management strategy implementation, we reduced the trouble calls and interruptions to customer service by 21% over a period of 3 years and we reduced SF6 gas leaks by 26%.”

The Woodhouse Partnership would be delighted to show you how our gap analysis, road mapping, and implementation processes can be applied to benefit your business, contact us now for a free initial consultation. We look forward to hearing from you.


“In conclusion, Hydro One’s relationship with Woodhouse has aid us considerably in improving our asset management practice and realizing significant value for our company and our customers.”
