A Call for Leadership – The Nation’s
aging electro-mechanical electric grid
cannot keep pace with innovations in the
digital information and telecommunications network. Power outages and
power quality disturbances cost the
economy billions of dollars annually.
America needs an electric superhighway
to support our information superhighway.
Each electric utility shall offer and
provide individual customers
upon customer request, a timebased rate schedule under which
the rate charged… varies during
different time periods

“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.

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
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

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
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

• Capital expenditure can be optimized based
on business value of various grid

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
System
Operations
Analytics
• 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
