The Problem
 Transmission Network planned operational changes must be
submitted, evaluated for regional reliability, approved or rejected, and
put into service through a managed process between an ERCOT and
member T&D Companies or other transmission service providers
 The existing processes are not fully automated and, therefore, labor
intensive and time consuming.
 Lack of uniform, automated electronic coordination also provides
opportunities for data errors in model changes through data translation
between applications and companies.
 Model inconsistencies between or within organizations cause
inaccuracies in reliability evaluation
 Partially automated processes and inconsistent models cause a
significant direct negative bottom line impact.

The Solution:
Siemens – Network (Common) Model Management System
(NMMS)
 A single coordinated master data source providing capability to feed
mission critical Operations, Maintenance and Planning applications
 Provides integrated tools to efficiently coordinate the workflow followed
in managing transmission network changes for the ERCOT and TSO’s
 Electronic submittal of planned network model changes in a standard
format
 Supports automated process for electronic approval or rejection
 Integrated tools enable rapid modification and resubmission of rejected
plans
 Supports convenient secure electronic access to approved plans
 Provides for integrated managed coordination of TSO planned network
changes with operations for the development of commissioning plans
 Support Audit and Dispute Resolution

Value Proposition/Benefits
 Significantly Reduced workload for ISO/RTO and T&D Planning and
Operations Staff
 Better control and accuracy of the Operating Model leading to
improved reliability management of the overall transmission network
(RTO and T&D)
 Improved Model accuracy leads to improved accuracy of congestion
management and resultant settlement financial solution by the RTO
 Improved Model provides accurate external network models for TFO
operations
 Provides a well synchronized method and tools to and initialization
planning models from the current operations model
