Architecture Tenets

InteroperableThe architecture will be capable

of integrating solutions fromdifferent vendors seamlessly into

multi-vendor solutions.

OpenThe architecture will enable theeasy integration of third-party or

in-house applications or products.

SecureSecurity will be build into the

design of the architecture and itscomponents, in such a way that

future systems can sustainknown or future forms of cyber

attacks.

ScalableThe architecture will be

configurable to meet the needsof small and large users alike,

using a common set of components and products.

ExpandableThe architecture will be able to

be expanded vertically andhorizontally, to accommodate

future end users needs, withouta wholesale replacement of its

hardware or software

components.

FlexibleThe architecture will enable theeasy addition or replacement of

its components, without awholesale replacement of the

system.

MaintainableThe architecture will minimize the

costs associated with routinemaintenance of the applications anddata. In particular, it will provide thecapability to maintain displays and

data concurrently, and will provide asingle access point for each

component

UsableThe architecture will promote

situation awareness by leveragingadvanced user interface concepts,and provide users with a common

look-and-feel, regardless of thenumber or origin of underlying

applications.

Independent The architecture will be

independent of underlying third-party technologies and products.

This will include as a minimum theOperating System, the Database

Management System and the

Middleware.

AccessibleIt will be possible for third-party or

in-house developers to accessshared data and services from

existing applications, relying solelyon existing documentation and

minimum amount of training.

Enables BusinessContinuity

The architecture will make provision for the mechanisms necessary to supportend users specific disaster scenarios

and associated requirements, up to thephysical loss of all facilities in a given

geographic area.

Standardized The architecture will promote a

high level of standardization andinterchangeability of its

components, and will adhere toapplicable Standards.



Scaled Deployment and the Smart Grid Investment GrantProgram

Midwest Focus

Scaled deployment of Automated Meter Infrastructure, Distribution Automation,Communications Network and Back office systems

Deployment underway in OH. Regulatory filings made in IN. Discussions underway in

KY. Carolinas’ Focus

Acceleration of routine system enhancements that’s been underway for several years

Evaluation of technology that would allow us to leverage our existing automated meter reading technology

Smart Grid Investment Grant $200 million for power delivery system modernization efforts in Ohio, Indiana, Kentucky

and both Carolinas.

Additional $4 million for transmission upgrades in the Carolinas

Additional $3.5 million for workforce development and training

Estimated job creation = approximately 1,000 across all five states10



THE “KEY ROOM”

11



Envision Energy

Umbrella project designed to test / pilot a number of newenergy technologies, including: Home Energy Management (phase 2)

First phase resulted in positive results with customers

saving an average of 8% each month Rooftop Solar Panels

Plug-in Electric Vehicle Charging

Energy Storage

Energy Optimization Distribution Energy Resource Management System

Smart Appliances

Weather Monitoring12



Envision: Charlotte

13

Envision: Charlotte is a unique public-private collaborationthat is leading Charlotte to become a global model for

environmental sustainability and measurable community results.

City initiative to improve overall sustainability inside Charlotte’s I-277 loop

Goal = reduce energy usage by 20% by 2016, avoiding 220,000 metrictons of greenhouse gases

Leverages digital smart grid technologies (Smart Energy Now) to

aggregate energy usage of 70+ buildings and display it on monitors as oneoverall number

Working prototype of lobby displays



SmartBuilding AdvantageSM

End-to-end pilot programleveraging smart gridtechnologies to gain energyefficiencies in commercial

buildings Early participants have

averaged 27% annual savingsand payback periods of two to

four years Sample of Current Customers:

Davidson College, CatawbaCollege, Presbyterian Hospital

Digital, smart grid technology is changing how we provide

energy to our customers. With detailed, frequent informationabout their electricity use, customers will have more control

and more choices. They'll be able to make better-informed

decisions about how they use electricity, saving them money

and benefiting the environment."

— Jim Rogers, Duke Energy chairman, president and CEO



Temas

Smart Grids continuarán en un proceso de evolución Smart Grid es el catalizador de cambio en nuestras operaciones de entrega

Aunque hay beneficios importantes para los clientes ……

Ahorros de costos donde hay flexibilidad de ajustar el consumo dentro del día

Información que ayuda a los clientes manejar mejor su demanda total (MW yMWh)

Vehículos eléctricos

……los beneficios de Smart Grid tienen que ver más con

modernización de la red eléctrica y optimización de generación Redes de distribución más confiables

Reducción en la necesidad para nueva capacidad de generación

Mejor utilización de generación de alta eficiencia

15



Temas - 2

Se debe manejar cuidadosamente las expectativas de los‘stakeholders’ en cuanto a ahorros y beneficios para la sociedad Value proposition no está efocada en una reducción inmediata de costos

Establecer programas pilotos con clientes que tienen mejor probabilidades de recibir beneficios a través de flexibilidad en su usode electricidad con tiempo Industriales

Intermedios grandes: universidades y hospitales

Vehículos eléctricos

16



Temas - 3

Estar preparados a responder a preocupaciones de clientes sobreprivacidad (de consumo)

Papel de gobiernos: Crear una plataforma a través de la cual los stakeholders puedan operar (p.e.

crear estandares) Dar un tratamento regulatorio razonable de los costos de los programas

Promover un entendimiento que hay beneficios tanto en el largo plazo como enel corto plazo

ADVANCED METERING INFRASTRUCTURE(AMI)

Smart Energy & The Smart Grid



These smart meters send metering data from the meter back to the Ambient Communications Node viaPower Line Carrier (PLC) technology. These smart meters have internal disconnect/reconnect capabilities.

ECHELON ELECTRIC “SMART” METER




These communication boxes send metering data (gas & electric) back to our systems.

AMBIENT COMMUNICATIONS NODE




These communication boxes send metering data (gas & electric) back to our systems.

AMBIENT COMMUNICATIONS NODE (CONT.)




DISTRIBUTION AUTOMATION (DA)





COMMUNICATIONS TO SUBSTATIONS/ RTUSServes as communication ‘pipe’ and ‘gateway’ into substation

S t E & Th S t G id




AUTOMATED CIRCUIT BREAKERS AND RELAYSAllows remote operation of breakers (open, close, block, un-block, e-tag) and remote data

acquisition (status, loading, fault current, voltage, PF, relay settings)
