Duke Energy Gas Transmission Receives Continuing Excellence Award from EPA
HOUSTON -- Duke Energy Gas Transmission (DEGT) has received a 2005 Natural Gas STAR Continuing Excellence Award from the United States Environmental Protection Agency (EPA). The award was given on Oct. 25 in recognition of DEGT’s ongoing efforts to reduce methane released into the atmosphere during the course of standard natural gas transportation operations. Methane is the primary component of natural gas.
DEGT’s U.S. transmission and storage business first entered the Natural Gas STAR program in 2000 and received a “Transmission Partner of the Year” award from EPA in 2002 after only one year of eligibility.
Methane can escape during pipeline venting and repair or, to a lesser extent, from valves and seals at compressor stations. DEGT uses four methods to reduce emissions: hot taps for new connections, sleeve repairs, pipeline pull downs and emergency shutdown practices.
Since the company’s original Natural Gas STAR recognition -- when it achieved 535 MMcf (million cubic feet) of avoided methane emissions in 2001 -- DEGT has reported avoided annual methane emissions of 931 MMcf in 2002; 1,030 MMcf in 2003; and 1,479 MMcf in 2004. In 2004 alone, the avoided methane emissions resulted in estimated cost savings of $8.9 million.
“We appreciate EPA’s recognition of our ongoing efforts to reduce methane emissions,” said Martha Wyrsch, president and chief executive officer of DEGT. “We are honored and proud to be known as good environmental stewards. Our efforts have also benefited our customers, saving money by reducing the amount of natural gas that in the past might have been lost during the transportation process.”
From 1993 to 2004, DEGT has quantified methane emission reduction of almost 7 billion cubic feet.
Membership in the Natural Gas STAR program is voluntary; about 100 natural gas-related companies are members.
DEGT’s methods of reducing methane emissions:
“We receive no monetary incentives from EPA to perform these emission reductions,” Wyrsch said. “However, implementing cost-effective measures to reduce the amount of natural gas otherwise vented to the atmosphere is good for our business. Our participation in the Natural Gas STAR program further builds our relationship with EPA and demonstrates our commitment to environmental stewardship.”
