Facilitating Growth in Texas

Source: Texas Comptroller of Public Accounts

Texas faces the challenge of

increasing energy demand, while

keeping costs affordable, ensuring

reliability and minimizing

environmental impact

• Texas added more than 4 million

people over the past 10 years;

population expected to increase 82

percent by 2060

= Resource adequacy issues

(energy, water, etc.)

• ERCOT predicts peak demand will

increase by 10 percent between now

and 2015

ERCOT Resource Adequacy

“All of the Above” Includes Demand-side

Resource adequacy is typically focused on the supply side of the equation,

which has been a challenge in Texas…

• Clean air rules

• Drought/water scarcity

• ERCOT competitive market structure

… But demand-side advances that Oncor and other utilities have been

making today can help consumers save money, improve reliability and

reduce supply-side constraints

Our Investments: Solving Real Problems

Building more than 1,000 miles of the

CREZ transmission grid to help meet

increasing demand with wind power and

other energy sources

Installing advanced meters to help

customers better manage their energy usage

and improve operational efficiency

Leveraging advanced technology to keep

pace with the operational demands of a 21st

century economy:

• Distribution automation

• Dynamic transmission line ratings

• FACTS technology

CREZ Transmission Build-out

• Texas posted a 13 percent increase in energy generated by

renewable sources in 2011

• ERCOT set a new wind power record on March 18, 2012

(7,917 MW; 24% of load at the time)

In 2005, the Texas Legislature

launched plans for developing

transmission infrastructure to

meet growing electric demands by

tapping Texas wind and solar

power, with the identification of

Competitive Renewable Energy

Zones (CREZ)

Oncor is one of eight companies

currently involved in the construction

and development process of CREZ

transmission lines, on track for

completion by year end 2013

Advanced Meters

More than 2.9 million advanced meters

installed On track for 2012 completion

System handling ~9 billion transactions

per month

Common Texas Web Portal launched

March 2010 “Green Button” compatible June 2012

Since March 2009, have executed 4.5 million

service orders remotely Eliminating 22.5 million miles driven

Saving 1.9 million gallons of fuel and 18,000 tons

of CO2

Biggest Energy Saver contest launched in

2011 to promote benefits Average savings of 26 percent for the top 10

percent of all contestants

Advanced Meters: Enhancing Reliability

Oncor’s Outage Management System (OMS)

integrated to AMS March 2012

Approximately 20% of

outages are resolved

without a customer ever

calling in the outage

~3% are meter removals,

transformer clearances,

tampering, data model, etc.

90% are confirmed

outages

To date, there have been no unexplained “false positives”

About 7% are found to be

power quality issues that

would have resulted in

an outage

Empowering Customer Energy

Management

In-home Energy Monitors

• To date, 14,581 in-home energy monitors have

been registered via the Smart Meter Texas web

portal

• Studies have shown that when customers are

provided energy-use information they can help

save 10-15%

“Smart” Thermostats

• Retail energy providers in ERCOT also offer

thermostats to help customers manage their

energy use

Energy Efficiency

From 2007-2011, Oncor spent more

than $300 million on energy efficiency

programs, which reduced:

• More than 485 MW of peak demand

• More than 1.335 million MWhs

• Annual greenhouse gas equivalent of

removing 180,501 cars from Texas

roads

Take a Load Off, Texas reached more

than 4 million customers and more

than 130,000 students through our 6th

grade curriculum program

Energy Efficiency In Action: Lady Bird

Johnson Middle School (Irving, TX)

Oncor worked with school administrators to create the largest “Net Zero” middle school in the U.S., producing more energy than it consumes through energy efficiency technologies and renewable power generation. Results have included:

• Solar Photovoltaic Roof Units

– 474 kW

– 913,133 kWh for $700,391

• Efficient Lighting

– 23 kW

– 108,400 kWh for $9,202

• Geothermal Units

– 68 kW

– 117,984 kWh for $28,558
