Advanced Grid Analytics: Asset Lifecycle Analytics focuses on understanding when to replace assets, and how to extend the life deteriorating assets • Electrical Assets deteriorate with usage, e. g. insulation, which will deteriorate when heated • Assets of same type will fail in a similar manner System Operations Analytics • Analysis of the historic usage of assets can be used to build a pattern that indicates the expected remaining life for existing assets • Prediction of historic life is improved when augmented with data from remote asset monitoring and off-line condition monitoring Data Warehouse • As assets start to fail, Remote Asset Monitoring may detect weaknesses which are only evident when the asset is loaded above a given level e. g. Dissolved Gas Analysis on transformers Asset Life Analytics – Operations can be adjusted to protect the asset, i. e. keep it loaded at a level that will extend its life © 2007 Center.

Advanced Grid Analytics: System Planning Analytics can reduce or delay capital expenditures, as well as help design networks that are cheaper to operate • Analysis of customer load patterns provides a detailed picture of which circuits need upgrading to avoid under-loading or overloading System Operations Analytics • The results from Asset Lifecycle Analytics can be used to optimize the planning of system maintenance • Detailed information on individual customer load patterns provides an opportunity to balance the load on each phase, reducing losses on the network Data Warehouse Asset Life Analytics • Capital expenditure can be optimized based on business value of various grid components © 2007 Center. Point Energy Proprietary and Confidential Information System Planning Optimization 15
Advanced Grid Analytics: System Operations Analytics can reduce or delay capital expenditures and improve reliability • Real-time analysis of faults can enable: – Grid reconfiguration to keep the system within safe limits • Analysis of meter energization and other power flow data allows faults to be analyzed off-line such that: – Field crews, with the right skills, are dispatched to the right place, with the right tools and the right parts for the job - so that restoration is faster Data Warehouse • Real time management of power flows can avoid over-loading circuits, avoiding or delaying the need to upgrade those circuits © 2007 Center.
