Increase shareholder value Increasing costs Labor Gas – Overall rates Copper, aluminum, steel – Transformers / conductors Vehicle Fuel Taxes and franchise fees Continued regulatory pressure to decrease rates Regulatory reliability concerns / awareness Northeast blackout Hurricane impacts Increasing Deregulated Texas Electric Market Demands on performance Increased management / accounting controls – Sarbanes / Oxley Aging workforce – both internal and field (Knowledge / Skill Transfer costs) Electric Utility Energy Market Changes Rapidly Changing Customer Needs

Current Electric Utility Environment The overall utility environment is demanding higher performance in an ever increasing cost environment.

“The greatest challenge facing electric distribution is responding to rapidly changing customer needs for electricity. Increased use of information technologies, computers, and consumer electronics has lowered the tolerance for outages, fluctuations in voltages and frequency levels, and other power quality disturbances.

power delivery system” Dynamically optimize the performance and robustness

• f the system

Continuous Monitoring

Quickly react to disturbances to minimize impact

Real Time Sensing & Responding

Identify and repair intermittent grid problems to minimize outages

Preventive

The smart grid initiative focuses on installing the smart meter system as a first stage to allow consumers to begin taking advantage of the benefits of smart

• meters. The next stage is to focus on grid automation.

Smart grid benefits

Key Stakeholder Consumers Electric Utility Retailers

• Enables more effective loading of utility assets (lines, transformers…)
• Enables increased monitoring and diagnostics to enhance the life of

utility assets

• Improved line fault detection and diagnostics
• Power quality and reliability improvements
• Friendly access to detailed consumption information to make informed

choices and enable faster transactions

• Enables and promotes energy conservation
• Expands retailer’s ability to offer new service offerings
• Enables time-of-use rates and critical peak pricing
• Establishes platform to offer future home appliance monitoring and

control

Environment

• Enables demand-side management
• Facilitates integration of solar and wind generation into grid
• Promotes energy efficiency through immediate energy consumption

awareness

Benefits

A smart grid will transform the way we buy, deliver and use electricity
