AIR QUALITY
We are pleased to report that our regulatory
compliance rate for air quality reached
98.8 percent in 2002. While many factors
contribute to this success, our commitment to
the environment runs throughout our
organization, beginning with plant managers,
engineers and operators who are charged with
being responsible for meeting all relevant local,
state and federal air-quality standards. Air
quality is a serious and time-consuming business,
and everyone at TXU works hard to make sure
that we achieve air-quality compliance.
NITROGEN OXIDE REDUCTIONS
HELP CLEAN THE AIR
Many metropolitan areas in the United States
remain challenged by high summer ground-level
ozone, and Texas is no exception. While
nitrogen oxide (NOx) emissions from mobile
sources like cars, trucks and diesel equipment
can be large contributors to high ozone levels,
factories and power plants can be contributors
as well.

TXU has taken a leadership role in Texas to
ensure that our NOx emission rates are good
and getting better. We have taken consistent
action over a number of years to reduce these
rates, and today these emission rates are 18
percent below the national average. As an
example, between 1990 and 2000 the company
saw a customer increase of 25 percent and still
was able to decrease NOx rates by 70 percent.
Even as we make today’s NOx reductions, we are
also planning for tomorrow’s reductions and
already have specific plans to remain compliant
with ever-changing laws and regulations.
DALLAS/FORT WORTH AREA NOx
RATE REDUCTIONS
With natural gas-fired power plants in and
around the ozone non-attainment area of the
Dallas/Fort Worth Metroplex, our NOx emission
reductions are important to air quality. Since
1997, we have made technical changes at these
plants to reduce NOx emission rates by more
than 42 percent. Through
