                  SOUTHEAST SUPPLY HEADER SIGNS ANCHOR SHIPPER

                CENTERPOINT ENERGY & DUKE ENERGY GAS TRANSMISSION
                          CONTINUE DEVELOPING PIPELINE

HOUSTON - Southeast Supply Header, LLC, has signed an agreement with Florida
Power and Light Company (FPL) for firm transportation service on its proposed
pipeline that will bring natural gas from east Texas and north Louisiana to
growing U.S. markets.

The agreement subscribes approximately half of the planned 1 billion cubic feet
per day capacity on the proposed Southeast Supply Header pipeline, which is
expected to be in service in June 2008. The agreement is contingent upon a
decision by the Florida Public Service Commission for FPL to recover the costs
it will incur under the agreement. That approval is expected in the fall of this
year.

During an open season held earlier this year, a number of other shippers
expressed interest in the project. Southeast Supply Header, LLC, is continuing
discussions with other interested shippers for the remaining capacity on the
pipeline.

The Southeast Supply Header is a joint venture between subsidiaries of
CenterPoint Energy, Inc. (NYSE: CNP) and Duke Energy Gas Transmission (DEGT).
The 270-mile, 36-inch diameter pipeline will extend from the Perryville Hub in
northeast Louisiana, which is owned by CenterPoint Energy's subsidiary,

Gas Transmission Company, to Gulfstream Natural Gas System, which is 50 percent
owned by an affiliate of DEGT. Along the route, the Southeast Supply Header will
access several major pipelines serving the eastern United States and have access
to several storage facilities.

"We are pleased to have FPL anchoring the Southeast Supply Header," said Cy
Zebot, chief commercial officer of CenterPoint Energy's pipelines group. "The
level of FPL's commitment is essential to achieving the scale needed to support
the capital investment required by such a project. We believe that FPL and its
customers will benefit from the supply diversity and flexibility that this
project will provide."

"This pipeline will help manage the growing appetite for natural gas in Florida
by providing access to natural gas onshore production from Texas and Louisiana,
by significantly increasing natural gas deliverability into both pipelines that
serve a majority of Florida, and by enhancing supply security and reliability
when weather events threaten production in the Gulf of Mexico," said Terry
Morrison, vice president of FPL's Energy Marketing & Trading division.

"We are very pleased to have reached this agreement with FPL," said Guy Buckley,
group vice president, DEGT. "The demand for natural gas continues to grow in the
Southeast and FPL plays a critical role in serving this region. The Southeast
Supply Header will ensure reliable access to growing supply regions through
interconnects with major interstate natural gas pipelines and provide supply
diversity for southeast and northeastern U.S. markets."

In June and July of 2006, Open Houses were held along the pipeline route to
introduce the project to local communities and begin the collaborative work

necessary to design a route that strikes a balance among affected landowners,
the environment and construction requirements.

The pre-filing process with the Federal Energy Regulatory Commission (FERC) has
been initiated, and an application is expected to be filed in November. Once the
project is approved by FERC, construction is anticipated to begin in the
November 2007 timeframe, with an expected in-service date of mid-2008.
