The energy criticality can be overlain on top of the asset overall criticality as shown on the Criticality and Energy Prioritization Chart. If the Sewage Lift Pump was also a high risk asset based on probability of failure and consequence of failure, it would be an extremely critical item for the utility to consider. If it appears critical only based on the energy considerations, it should be included within the context of all highly critical assets.
Overlaying the criticality of assets based on probability and consequence with energy criticality can identify assets that may be high in both categories. These assets would be extremely critical to the utility in terms of replacement. A discussion of decision making based on criticality is presented in Chapter 6. Both of the energy-related quad charts are available in Appendix C
