Regulated Business Model


Large Remote Generation


Less Restrictive Environmental Constraints


“Overbuild” to Account for Reliability and Load Growth


“Understanding” Customer Base



Now


Equivalent or Increased Reliability Objectives


Customer More Sensitive and less tolerant of Outages and Power Quality


Emerging “Customer Choice”


Significant Emission Restrictions


Distributed and Renewable Energy Resources


Infrastructure Overbuild Limitations


Equipment Utilization Approaching Design Limitations in Loading and Lifecycle


Compounded by Aging Workforce Issues

ESRI, SmallWorld and Intergraph GIS solutions.

Existing

Future


Committee continually expands CIM data model to cover a broader range of
applications which will support exchange of data between Asset
Management, Network Modeling, and Distribution Management System
components. This evolution will lead to condition

decision support and operational contingency planning.

What Exists Today And Future Functionality To
Deliver Smart Grid Data?


Broadband wired, wireless and BPL networks already exist


Wireless mesh networks can support incorporation of grid asset
communication, but currently require additional infrastructure to reduce
recursive communication between meters and meters to towers. These could
be converted to broadband IP
-
based networks as cost comes down.


Domain provisioning available to support low latency communication

Existing

Future


WiMax, LTE (
Long Term Evolution (3GPP 4G technology)

at various frequencies
(licensed and unlicensed) and white space frequency spectrums will emerge
that will support more robust IP communications as wireless surpasses most
wired broadband networks, with dynamic encryption key generation for
