Financial & Operating Highlights

• Year-to-date net income up 18 percent and earnings per share up 19 percent

• Announced Palomar Gas Transmission Joint Venture to develop a new natural gas pipeline into Oregon

• About 1.7 billion cubic feet (Bcf) of interstate gas storage capacity to be added to Mist field through development drilling

PORTLAND, ORE.—Northwest Natural Gas Company, dba NW Natural (NYSE: NWN), reported net income for the second quarter ended June 30, 2007 of $2.6 million, or 10 cents per share, up from $2.0 million, or 7 cents per share in the same quarter of 2006.

For the six month period, net income was $50.7 million, or $1.86 per share, compared to $43.0 million or $1.56 per share for the first six months of 2006, representing a 19 percent increase in earnings per share.

“Our strong financial performance comes from continued solid customer growth in our utility operations, strong performance from our gas storage activities, and a constant focus on the fundamentals of the business,” said Mark Dodson, chief executive officer.

“While continuing to implement our new operations model, the company is looking ahead to future growth opportunities, including the proposed Palomar pipeline project, which is expected to add incremental earnings growth in the next decade and beyond. Our overall goals remain unchanged: to deliver high-quality service to existing and future customers, while generating a strong total return for shareholders.”

Second quarter financial and operating highlights

• Higher net income and earnings per share

Net income in the second quarter of 2007 was $2.6 million or 10 cents per share, compared to $2.0 million or 7 cents per share in 2006. Results from utility operations are typically low during the second quarter due to the reduced use of natural gas in spring and early summer. The utility had a small net loss of $0.1 million, or less than 1 cent per share, compared to net income of $0.2 million, or 1 cent per share in the second quarter of 2006. Gas storage contributed $2.7 million in the second quarter of 2007, equal to 10 cents per

share. This compares with $1.8 million in the second quarter of 2006, or 6 cents per share. Other non-utility activities resulted in a negligible gain for the quarter, compared to a small loss in 2006.

• Palomar Gas Transmission LLC formed

On August 6, 2007, NW Natural and TransCanada Pipelines Limited (TransCanada) announced the formation of a joint venture to develop a new natural gas pipeline to serve Oregon and other western U.S. markets. If constructed, the new transmission line is scheduled to begin service in late 2011. Palomar Gas Transmission LLC (Palomar) was formed by NW Natural and Gas Transmission Northwest Corporation (GTN System), a subsidiary of TransCanada (NYSE, TSE: TRP), to develop, design, permit, construct and own the Palomar pipeline. Palomar will require approval from the Federal Energy Regulatory Commission (FERC) to build and operate the pipeline.

As contemplated, the 110-mile eastern section of the Palomar pipeline would connect the existing GTN System in north-central Oregon with NW Natural’s distribution system near Molalla, Oregon, 30 miles southeast of Portland. NW Natural has contracted for approximately 100 million cubic feet per day of capacity (100,000 Dth/day) on the eastern portion of the proposed Palomar pipeline for utility customers starting in 2011.

The Palomar project is being designed so that, if a liquefied natural gas (LNG) terminal is constructed on the Columbia River, the pipeline could be extended to approximately 220 miles in total length to serve the LNG terminal. NorthernStar Natural Gas, the developer of the proposed Bradwood Landing LNG terminal on the Columbia River, may elect to use capacity on the Palomar pipeline. NW Natural has also entered into an agreement with Palomar Gas Transmission for 100 million cubic feet per day of capacity (100,000 Dth/day) on the proposed western portion of the Palomar pipeline, if that section is built.

Palomar’s estimated investment for the initial 110-mile eastern section of the project is $300-350 million in current dollars, and $600-700 million to complete the full 220-mile pipeline. Initial development costs over the next two years are expected to total $25-30 million, primarily relating to permitting activities. TransCanada, through GTN, and NW Natural will be equal owners in the pipeline.

• Mist field to add 1.7 Bcf of reserves

NW Natural continues to expand the Mist gas storage field in northwest Oregon with the drilling of the St. Helens reservoir earlier this year and the addition of new injection and withdrawal wells. When the project is complete in November, Mist’s storage capacity will increase from 14.1 billion cubic feet (Bcf) to 15.8 Bcf. The facility will also increase throughput to 515 million cubic feet of gas per day, up from about 440 million cubic feet of gas per day.

• Customer growth remains strong in region

NW Natural’s customer growth continues at a rate higher than the national average. This growth is driven by new construction activity and conversions from other fuel sources. At June 30, 2007, the company had 640,641 customers, for a growth rate of 2.6 percent over the past 12 months.

• Operational results on target

NW Natural’s total gas sales and transportation deliveries in the second quarter of 2007, excluding deliveries of gas stored for others, were 234 million therms, or 2 percent higher than the 230 million therms delivered in 2006, due mainly to higher residential and commercial customer usage during the period. Margin from utility operations was $59.1 million, 2 percent higher than the $58.0 million of utility margin in 2006. Sales to residential and commercial customers in the second quarter of 2007 were 103 million therms, 8 percent higher than last year’s 95 million therms, due primarily to higher usage in the period resulting from weather that was 22 percent colder than in 2006 and 2 percent colder than average. Residential and commercial sales contributed $51.2 million to margin, up 8 percent from a margin contribution of $47.3 million in 2006. The company’s weather normalization and decoupling mechanisms in Oregon reduced margin by $0.8 million in the second quarter of 2007, compared to a negligible reduction to margin from these mechanisms in the second quarter of 2006. Gas deliveries to industrial customers in the second quarter were 132 million therms, down 2 percent from 134 million therms last year, while margin in this sector was $7.5 million, slightly lower than last year’s industrial margin of $7.7 million.

NW Natural continues to provide gas storage services to customers in the interstate and intrastate gas markets from its Mist gas storage field, primarily using storage capacity that has been developed in advance of core utility customers’ requirements. Earnings from gas storage in the second quarter of 2007 were $2.7 million, or 10 cents per share, compared to $1.8 million, or 6 cents per share, in the second quarter of 2006. These results include income from gas storage services as well as income from a contract with an unaffiliated energy marketing company that optimizes the company’s unused storage and pipeline transportation capacity.

NW Natural has an annual Purchased Gas Adjustment (PGA) tariff in Oregon and Washington to reflect projected gas costs in customer rates. In Oregon, the company absorbs 33 percent of any excess cost of gas, or retains 33 percent of any gas cost savings, both as compared to the projected gas commodity prices built into rates. The company also retains 33 percent of the margin when it sells surplus gas commodity off-system, and credits 67 percent to customers.

For the second quarter of 2007, $2.4 million of gas cost savings were deferred for later credit to customers due to the company’s commodity cost sharing mechanism. NW Natural’s share of the commodity savings in the quarter contributed $0.8 million to margin in the period, equivalent to 2 cents per share of earnings. In Washington, 100 percent of all gas costs are passed through to customers.

• Operations and maintenance costs kept in check

Operations and maintenance expenses in the second quarter of 2007 increased about 2 percent over last year. The increase was primarily due to higher employee benefit expenses and increased staffing related to a customer call center. Bad debt expense as a percent of revenues billed remained well below one percent (0.30 percent) for the 12 months ended June 2007.

According to Chief Financial Officer David Anderson, “We continue to see progress in keeping our O&M costs below our rate of growth as we implement our operations model changes. In addition, as announced last quarter, we committed to investing an additional $5 million in infrastructure, safety and reliability projects to take advantage of opportunities from our strong financial performance in the first quarter. We began making these investments in the second quarter, and anticipate making further improvements to our system over the balance of the year.”

• Moody’s Investors Service changes company’s debt rating outlook to positive from stable and NW Natural completes $250 million credit facility

Moody’s Investors Service changed NW Natural’s ratings outlook to positive from stable in July 2007. According to Moody’s, the change in outlook reflects the company’s improving credit status as evidenced by the company’s growth in earnings, strong balance sheet and cash flows from operations, conservative financial management and manageable customer growth under a supportive regulatory framework. The company’s senior secured debt rating of A2, the senior unsecured debt rating of A3 and its commercial paper rating of P-1 were reaffirmed.

On May 31, 2007, NW Natural established a $250 million syndicated credit facility, which is used primarily to provide back-up support for notes issued under its commercial paper program. This credit facility, which has a five-year term, replaced credit lines totaling $200 million that were due to expire in 2010.

Year-to-date (six month) financial and operating highlights

• Higher net income and earnings per share

For the six month period, net income increased 18 percent to $50.7 million or $1.86 per share, compared to $43.0 million, or $1.56 per share, in the same period in 2006. NW Natural’s utility operations contributed $46.0 million or $1.69 per share in the first six months of 2007, compared to $39.7 million, or $1.44 per share in 2006 for a 17 percent increase in earnings per share. Gas storage contributed $4.5 million in the period, or 16 cents per share, compared to $3.3 million in 2006, or 12 cents per share. Other non-utility activities resulted in net income of $0.2 million, or 1 cent per share, compared to $0.1 million, or less than 1 cent per share in 2006.

• Operating results show higher sales and efficiency gains

NW Natural’s total gas sales and transportation deliveries in the first six months of 2007, excluding deliveries of gas stored for others, were 647 million therms, up 1.5 percent from 2006 due to higher residential and commercial volumes. Margin from utility operations was $194.7 million, compared to $180.4 million in 2006, or 8 percent higher than last year’s first six months.

Gas sales to residential and commercial customers in the first six months of 2007 were 363 million therms, up 4 percent from 2006 on strong customer growth and from weather that was 7 percent colder than last year but average for the period. Residential and commercial sales contributed $164.6 million to margin, up 5 percent from $157.4 million in 2006, due mainly to customer growth and colder weather than last year. The company’s weather normalization and decoupling mechanisms contributed a net $0.4 million to margin for the first six months of 2007. This compares to a margin contribution of $0.8 million from these mechanisms for the same period in 2006.

Gas deliveries to industrial customers in the first six months of 2007 were 284 million therms, down 1 percent from 288 million therms in the same period last year. Contribution to margin from sales and transportation in these markets was $15.9 million, compared to $16.2 million, down 2 percent from last year.

For the first six months of the year, $24.1 million of gas costs were deferred for later credit to customers due to the company’s commodity cost sharing mechanism. NW Natural’s share of the commodity savings contributed $10.6 million to margin for the first six months of the year, equivalent to 24 cents per share of earnings. All gas costs are passed through to customers in Washington.

• Cash flows and capital structure

Cash provided by operations in the first six months of 2007 was $180.3 million, compared to $134.7 million in the same period in 2006. Cash flows reflect improved operating results, deferred gas costs and working capital differences. Cash used in investing activities totaled $52.5 million, up from $37.6 million in 2006, mainly reflecting increased investment in gas storage facilities.

NW Natural’s capitalization at June 30, 2007 reflected 52.2 percent common equity, 44.2 percent long-term debt, and 3.6 percent short-term debt, compared to 51.4 percent common equity, 41.4 percent long-term debt, and 7.2 percent short-term debt at June 30, 2006.

During the first half of the year, NW Natural repurchased 509,500 shares of its common stock as part of the company’s previously announced share repurchase program. As of June 30, 2007, the company had 26.8 million shares outstanding.

Outlook for 2007

NW Natural confirmed its prior estimate that its full-year earnings per share in 2007 will be in the range of $2.50 to $2.65.

The company continues to target long-term earnings per share growth of 5 percent or more and to maintain a dividend payout ratio of 60 to 70 percent of earnings.
