Examples of Cable Evaluation Experience


Portland General Electric serves over 800,000 customers in Western Oregon. As part of their Strategic Asset Management Program development in 2013, they developed an economic life model to evaluate cable. Because PGE’s field crews have collected detailed failure data going back nearly 40 years, robust and customized correlations between age and insulation type were possible. PGE’s cable model recommends a large program of replacement and injection of aging XLPE cable. This recommendation is working its way through the budgeting and capital review process on its way to the rate case.

Toronto Hydro is a large regulated utility serving over 700,000 customers in the greater Toronto area. Their asset management team developed and implemented a cable tool as part of their Feeder Investment Model. The Feeder Investment Model, including cable analysis, has been used by Toronto Hydro’s regulatory group as part of multiple rate cases before the Ontario Energy Board, requesting spending increases for, among other things, cable intervention. The approach was singled out by the OEB for praise in their opinion.

Tacoma Power is a municipal utility serving 160,000 customers in the Puget Sound region. They implemented an economic life model for planning cable investments in 2010 and are now using it as the basis for the a large budget for cable replacement and injection.

PowerStream serves nearly 400,000 customers in communities near Toronto. They implemented an underground cable model in 2008, used to provide a long-range cable intervention strategy. PowerStream was created by consolidating multiple smaller utilities, so finding consistent and reliable data was a challenge. They relied heavily on the experience of subject- matter experts to approximate installation history and customer information.

Idaho Power is a private, regulated utility serving 400,000 customers in Idaho, Utah, and Oregon. They developed a cable model in 2008, which was the basis for a long-range cable replacement and injection program. Meanwhile, Idaho Power continues to evaluate and improve input assumptions and data.
