Government response to changing customer needs

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)

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

Asset Life Analytics

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

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
