3. U.S. Divided into Eight
Reliability Regions
• The eight reliability regions in the FERC
continental U.S. are subject to the
oversight and enforcement authority of NERC
the North American Electric Reliability
Corporation (NERC), which is subject to
the Federal Energy Regulatory
Commission’s (FERC) oversight. NERC
is responsible for developing standards
to ensure and improve reliability for
delivery of electricity on the bulk power
system.
• Electric systems in Texas are located
within four separate reliability regions:
- Texas Regional Entity (TRE),
which oversees participants in the
Electric Reliability Council of
Texas (ERCOT);
- SERC Reliability Corporation;
- Southwest Power Pool (SPP); and
- Western Electricity Coordinating
Council (WECC).
(ERCOT)

Electric Usage Up

7. Background
• Heating Degree Days (HDDs) are an indicator of how cold it is,
and how much energy is required to heat one’s home
• HDDs are calculated each day as follows: 65° – (Avg. Temp)
• A higher number of HDDs indicates colder conditions
• In Dec 09 and Jan 10, areas in Texas experienced more HDDs
than normal – as a result, energy usage increased
• Parts of Texas are in the midst of one of the coldest winters on
record

• Using Killeen as an example, heating degree days are far higher than last year,
making increased electric consumption and bringing higher bills.

Increased Energy Usage
Texas power usage sets
another winter record
January 8, 2010
Electricity usage in Texas rose Friday as arctic air covered most of the state, hitting
another winter power record after setting one just the night before, according to initial data
from the state grid operator.
The Electric Reliability Council of Texas (ERCOT) said power use as of 8 a.m. CST (9
a.m. EST) reached 55,856 megawatts, surpassing the winter peak set Thursday evening of
52,001 MW and the previous record of 50,408 MW in February 2007.
ERCOT reported no major power problems.
Temperatures across Texas are running about 15 to 20 degrees Fahrenheit below normal,
according to DTN Meteorlogix.

10. Key Factors Affecting Electricity
Consumption in Winter
• Age of home
• Size of home
• Insulation
• Efficiency of heating equipment
• Thermostat setting
• Seasonal lighting
• Longer use of lighting
• Increased use of electronics
• Increased run times for pool equipment

12. Energy Efficiency Tips
• Check insulation
• Install a programmable thermostat
• Check your air filter
• Change light bulbs to compact fluorescents
• Avoid lighting empty rooms
• Caulk and weather-strip all doors and windows
• Keep shades and curtains open during the day on the south
side of your home
• Make sure radiators and vents aren’t blocked
• Make sure fireplace damper is closed when not in use

13. Energy Efficiency in Texas:
Overview
• Texas continues to be an energy leader through policies designed to improve
the state’s energy efficiency programs and bring improved technologies to the
electric market.
– Utility-run programs have reduced customer consumption, thereby reducing the need
for the construction of new generation.
– Advanced metering provides information and opportunities that enable customers to
take better control of their energy consumption and bills.
– Houston and Dallas-Fort Worth ranked 1 and 2 nationally in number of homes that
qualified for EPA’s “Energy Star” designation.
• The Texas Electric Choice Act requires electric utilities to provide energy
efficiency programs and incentives, including efficiency programs for low-income
customers.
• ERCOT competitive retailers are developing innovative plans and products
designed to help customers use less energy (e.g., customer education
programs, energy audits, programs to benefit from use of Internet-controllable
thermostats, etc.)

14. Energy Efficiency Programs
Have Exceeded Goals
Total Energy Savings by Investor-Owned Utilities
2003 - 2008
• In 2008, utilities in Texas achieved 202 MW of peak demand reduction in 2008, which was
76% above their 115 MW goal.
• Utility programs implemented for the years 1999 through 2008 have put measures in place
that produced 1,125 MW of peak demand reduction and 3,014 GWh of energy savings.

15. Energy Efficiency Resources
• Customers can contact their electric utility to find out what programs
are available, or to find a contractor or vendor who participates in the
state energy efficiency programs.
• Customers can call 2-1-1, the Texas Health and Human Service
Commission's information and referral network to learn about programs
available in the area.
• Additional resources:

16. Benefits of Advanced Metering
• Advanced meters and other new technologies
and associated infrastructure will provide information
and opportunities that will enable customers to better
understand the impact of controlling their energy
consumption.
• By controlling their energy consumption, customers
can better manage their bills and lessen their
environmental impact.
• Advanced meters will allow for more automation of utility functions such
as meter reading and connections/disconnections, which help to reduce
costs.

18. Advanced Metering Activities
in Texas
• The approved deployment plan for CenterPoint Energy calls for installation of advanced
meters over five years beginning in March 2009. In 2009, CenterPoint Energy was named
as a recipient of a Federal Smart Grid Investment Grant that should enable installation of all
meters by late 2012. Through year-end 2009, CenterPoint Energy installed 152,275
advanced meters, and another 42,815 were installed in January 2010.
• Oncor’s approved deployment plan initiated in late 2008 will have installation of advanced
meters completed by the end of 2012. To date, Oncor has installed 709,435 meters.
• The AEP Texas deployment plan was approved in December 2009 and installation of
advanced meters will be completed by the end of 2013. To date, nearly 5,000 meters have
been installed in Portland, Texas, in order to conduct a system acceptance test. Full-scale
deployment will begin in the second quarter of 2010.
• The cost for the meters and associated communications and computer equipment will be
recovered through a monthly surcharge, which can be adjusted over time to reflect both the
inclusion of AMS costs in future base rates and variances between the estimated versus the
actual cost of implementing the deployment plan. The respective surcharges for both Oncor
and CenterPoint Energy take into account the savings advanced meters are expected to
bring each company.
