EX-99.1

CHARLOTTE, N.C., Dec. 10 /PRNewswire-FirstCall/ — Piedmont Natural Gas (NYSE: PNY) today announced results for the fiscal year and for the fourth quarter ended October 31, 2004, subject to completion of its annual audit.

For the 2004 fiscal year, the Company reported net income of $95.2 million, or $1.27 per diluted share, which includes $4.6 million, or $0.06 per diluted share, for one-time items reported during the first fiscal quarter. These results compare with net income of $74.4 million, or $1.11 per diluted share, for the 2003 fiscal year. Weather for the 2004 fiscal year was 9% warmer than 2003, and 5% warmer than normal. Per share results reflect the two-for-one stock split that occurred in October.

For the three months ended October 31, 2004, the Company’s seasonal fourth-quarter loss was ($12.5 million), or ($0.16) per diluted share, which includes the previously announced $7.0 million accrual, or ($0.05) per diluted share, for the initial funding of the Piedmont Natural Gas Foundation. The funding of the Foundation occurred in November. These results compare with a seasonal loss of ($5.0 million), or ($0.07) per diluted share, for the prior-year fourth quarter.

Fiscal year 2004 and the fourth quarter of 2004 include the results associated with the Company’s North Carolina Natural Gas (NCNG) division, which was acquired on September 30, 2003. Fiscal year 2003 and the fourth quarter of 2003 include only one month’s results from the NCNG division.

System throughput for fiscal year 2004 totaled 201.3 million dekatherms, compared with throughput of 149.3 million dekatherms for the previous year. Throughput for the fourth quarter totaled 34.1 million dekatherms, compared with 25.3 million dekatherms for the previous year’s quarter. The annual and quarterly increases are primarily due to the acquisition of NCNG and continued customer growth across the Company’s three-state market area.

Margin for the year and quarter increased by $105.5 million and $14.4 million, respectively. These increases are primarily attributable to the NCNG acquisition, rate increases for the Company’s NCNG and Nashville Gas divisions that became effective November 1, 2003, and customer growth. Operations and maintenance expenses for the year and quarter increased primarily due to the acquisition of NCNG.

Other income (expense), net of income taxes, was $15.3 million for the year and ($4.0) million for the quarter, compared with $12.3 million and $1.3 million for the same periods of the prior year. The current year and quarter include the previously mentioned $7.0 million accrual for the initial funding of the Piedmont Natural Gas Foundation. Fiscal year 2004 results include one-time items for the gain on the sale of the Company’s propane interests and the resolution of certain disproportionate sharing issues related to the Company’s interest in the SouthStar Energy Services venture. Both occurred during the first fiscal quarter of 2004 and totaled $4.6 million, net of income taxes. The avoidance of summer seasonal propane losses as a result of the sale of that venture improved the comparisons.

Included in other income (expense) are the results from the Company’s joint venture, non-utility activities. The Company’s interest in SouthStar contributed $11.9 million to net income for fiscal 2004 and $0.4 million in the fourth quarter, compared with $6.4 million and $0.7 million for the same periods of the prior year. Two other joint ventures, Pine Needle LNG and Cardinal Pipeline, contributed combined net income of $3.5 million for fiscal 2004 and $0.9 million in the fourth quarter, compared with $3.1 million and $0.7 million for the same periods of fiscal 2003.

“We had an outstanding year in 2004, primarily as a result of our opportunistic acquisition of NCNG and the strategic restructuring and operating performance of our joint venture, non-utility activities,” commented Thomas E. Skains, Chairman, President and Chief Executive Officer. “Our strong non-utility earnings enabled us to fund the Piedmont Natural Gas Foundation which will provide valuable assistance to qualified charitable agencies and organizations where our employees live, work and provide service to our customers.”

At the Company’s regular quarterly Board of Directors meeting held today, a quarterly dividend on Common Stock of 21.5 cents per share was declared, payable January 14, 2005, to holders of record at the close of business on December 22, 2004.

The Company has recently initiated a business process improvement program across its three-state operating area in order to achieve cost efficiencies and improve customer service. Some of the process improvement initiatives scheduled for implementation include consolidating the Company’s customer call centers and regional business offices, automating meter reading functions, and consolidating some of the Company’s smaller local business offices into nearby, larger district offices.

The Company will implement these major process improvement initiatives on a phased-in schedule over the next two to three years. The impact of these initiatives in fiscal year 2005 is reflected in the Company’s previously announced earnings guidance for the year.

“We are keenly focused on continuous business process improvement and operating our gas distribution systems as efficiently and cost-effectively as possible,” commented Mr. Skains. “At the same time, we are determined to enhance and improve customer service and satisfaction which has never had a greater importance in light of current market conditions in our industry,” he said.

Piedmont Natural Gas reaffirms its guidance issued on August 27, 2004, for fiscal year 2005 earnings from continuing operations in the range of $1.23 to $1.30 per diluted share. The 2005 earnings guidance assumes normal weather, a relatively stable economy and wholesale natural gas prices in the range of prices that prevailed during fiscal year 2004. No general rate case activity is expected that would impact 2005 earnings in any of the Company’s jurisdictions.
