  3. CenterPoint Energy – Houston • Chartered in 1882 • 5,000 square-mile service area • 3 million metered customers • 73.6 billion kilowatt hours delivered yearly for about 60 certified competitive retailers • Transmission and Distribution System • 3,640 miles of transmission lines • 41,913 miles of distribution lines • 225 substations Challenge: Effectively monitor and control millions of meters, line devices and miles of delivery wire which if laid end to end almost circle the earth twice around the equator

  4. Government Response to Changing Customer Needs Dept of Energy & FERC DOE “Grid 2030” “A National Vision for Electricity’s Second 100 years” A Call for Leadership – The Nation’s aging electro-mechanical electric grid cannot keep pace with innovations in the digital information and telecommuni-cations network. Power outages and power quality disturbances cost the economy billions of dollars annually. America needs an electric superhighway to support our information superhighway. (US DOE July 2003) PURPA - Pubic Utility Commission Each electric utility shall offer and provide individual customers upon customer request, a time-based rate schedule under which the rate charged… varies during different time periods (Public Utilities Regulatory Policy Act - PURPA) FERC “Assessment of Demand Response & Advanced Metering” Demand response has an important role to play in both wholesale and retail markets... Staff encourages states to consider ways to actively encourage demand response at a retail level. (August 2006 Staff Report)

  5. Government Response to Changing Customer Needs PURPA - Pubic Utility Commission Each electric utility shall offer and provide individual customers upon customer request, a time-based rate schedule under which the rate charged… varies during different time periods (Public Utilities Regulatory Policy Act - PURPA) • Texas-Set 3.0 PUC Terms & Conditions • Same day reconnect for non-pay • More timely completion of DNP, move-in and move-out work • Fewer allowed estimated readings • TDU accountable for bill after 3rd consecutive estimate • No aging of DNP workloads • (August 25, 2006) • Texas PUC Projects • Advanced metering and • time-differentiated pricing • Hardening of the Grid • Terms & Conditions • Texas Nodal • (August 2006)

  6. Business Transformation with an “Intelligent Grid”The Intelligent Utility Network: • Improves reliability • Increases Competition • Improves customer satisfaction • Easy fast and accurate customer switching • Removes barriers for smaller REP entry • Enables hardening of the grid

  7. What is the Intelligent Grid? Internet Web Services The Intelligent Grid links electricity with communications and computer control to create a highly automated, responsive and resilient power delivery system.

  14. Advanced Grid Analytics: Asset Lifecycle 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 • 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 • 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 • Operations can be adjusted to protect the asset, i.e. keep it loaded at a level that will extend its life System Operations Analytics System Planning Optimization Data Warehouse Asset Life Analytics

  15. Advanced Grid Analytics: System Planning 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 • 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 • Capital expenditure can be optimized based on business value of various grid components System Operations Analytics System Planning Optimization Data Warehouse Asset Life Analytics

  16. System Operations Analytics System Planning Optimization Data Warehouse Asset Life Analytics Advanced Grid Analytics: System Operations 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 • Real time management of power flows can avoid over-loading circuits, avoiding or delaying the need to upgrade those circuits

  17. The cost/benefit value of an Intelligent Grid is asymmetrical while the benefits are shared end-to-end across utilities, retailers, system operators and customers.
