A power plant-integrated measurement and monitoring system, comprising: a first sampling port disposed in a first set of pipelines in the power plant that convey liquid fuel from a liquid fuel source to a dirty storage tank, the first sampling port configured to provide a load sample of the fuel, the load sample representing the fuel provided by the fuel source prior to storage, processing, or both; a second sampling port disposed in a second set of pipelines in the power plant downstream from a downstream component, the downstream component configured to store, process, or store and process the fuel downstream from the dirty storage tank, and the second sampling port configured to provide a sample of the fuel downstream of the downstream component representative of fuel after processing, storage, or both of the fuel by the downstream component; and an automated analyzer device configured to: analyze the load sample to determine quality attributes of the load sample; analyze the post-downstream component sample to determine quality attributes of the post-downstream component; and provide the quality attributes of the load sample md the quality attributes of the post-downstream component sample to a distributed control system, the distributed control system configured to identify anomalies in the fuel and attribute the anomalies as either an initial quality of the liquid fuel as it is supplied by the fuel source or likely caused by the downstream component; wherein the plant-integrated measurement and monitoring system is configured to report the conditions of and/or adjust the operation of equipment in the power plant based in part on an analyzed quality of the liquid fuel samples provided at said first and second sampling ports (36, 44) of the power plant. a first sampling port disposed in a first set of pipelines in the power plant that convey liquid fuel from a liquid fuel source to a dirty storage tank, the first sampling port configured to provide a load sample of the fuel, the load sample representing the fuel provided by the fuel source prior to storage, processing, or both; a second sampling port disposed in a second set of pipelines in the power plant downstream from a downstream component, the downstream component configured to store, process, or store and process the fuel downstream from the dirty storage tank, and the second sampling port configured to provide a sample of the fuel downstream of the downstream component representative of fuel after processing, storage, or both of the fuel by the downstream component; and an automated analyzer device configured to: analyze the load sample to determine quality attributes of the load sample; analyze the post-downstream component sample to determine quality attributes of the post-downstream component; and provide the quality attributes of the load sample md the quality attributes of the post-downstream component sample to a distributed control system, the distributed control system configured to identify anomalies in the fuel and attribute the anomalies as either an initial quality of the liquid fuel as it is supplied by the fuel source or likely caused by the downstream component; analyze the load sample to determine quality attributes of the load sample; analyze the post-downstream component sample to determine quality attributes of the post-downstream component; and provide the quality attributes of the load sample md the quality attributes of the post-downstream component sample to a distributed control system, the distributed control system configured to identify anomalies in the fuel and attribute the anomalies as either an initial quality of the liquid fuel as it is supplied by the fuel source or likely caused by the downstream component; wherein the plant-integrated measurement and monitoring system is configured to report the conditions of and/or adjust the operation of equipment in the power plant based in part on an analyzed quality of the liquid fuel samples provided at said first and second sampling ports (36, 44) of the power plant.
