51317--9796-Alignment of Reject/Ranking Criteria With Mitigation Methods and its Impact on O&M Funds

Service and design life estimates are converging for many transmission and distribution assets. This report provides an approach to understanding the significance of reject and ranking criteria and how they may become a barrier to good asset management or a path to improving system reliability and grid resiliency.

Service life and design life estimates are quickly converging for many transmission and distribution assets. Replacement costs have escalated due to new constraints that were not considered in early days of developing the power grid. As a consequence the maintenance funds must be optimized to maximize results of the life extension methods.This may be achieved by modeling the margins between operating loads and the structure conditions to study the impact of the ranking criteria on population distributions. Aligning the mitigation methods efficacy and cost with the ranking criteria then provides an understanding of the balance between risk and cost.This report provides an approach to understanding the significance of reject and ranking criteria and how it may become a barrier to good asset management or a path to improving system reliability and grid resiliency.Keywords:Inspection and assessment Reject and Ranking criteria Asset Management Operations and Maintenance

Key words: Power transmission, power distribution, Inspection and assessment, Reject and Ranking criteria, Asset Management, Operations and Maintenance
