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
