Integrated Energy and CommunicationsSystem Architecture (IECSA)

IECSA is an open, standards-based systemsarchitecture for the data communications networks

and intelligent equipment necessary to support thepower delivery infrastructure of the future.


4/15

IECSA Project Objectives

Develop a complete set of systems requirements and architecturedocuments to support industry-wide enterprise architecture for aself-healing grid and integrated consumer communicationsinterface.

Contribute project results as appropriate to relevant standardsdevelopment organizations and industry consortia to effectivelymove the development of key open standards forward to developa robust industry infrastructure.

Apply systems engineering to the development of the architectureincluding but not limited to: the elicitation and management ofsystem requirements, analysis of requirements and developmentof proposed architectural designs, evaluation of architecturaldesigns and the use of standardized industry notation fordocumentation of architectural views.

Identify the potential for infrastructure sharing and synergybetween power engineering operations and other applicationdomains.

Approaches to Technology Development

Develop a technology, find uses for it Identify a problem, select or develop a technology to solve it Identify domain requirements, select, develop or improve

technologies that address the requirements

FCC Goals

The FCC wants to leverage broadband power line technology to:1. improve the competitiveness of the broadband service

market;2. increase the availability of broadband services in

underserved areas;

3. encourage the uses of these advanced technologies toimprove safety and efficiency of power distribution byadding intelligent networking capabilities to the electric grid
