Cascade Natural Gas Corporation Announces Fiscal Year 2004 Third Quarter and
Year-to-Date Results

     SEATTLE--(BUSINESS WIRE)--July 27, 2004--Cascade Natural Gas Corporation
(NYSE:CGC) reported a loss of $666,000 or $0.06 per share for the fiscal third
quarter ended June 30, 2004, compared to a loss of $2.0 million or $0.18 per
share for the third quarter ended June 30, 2003. Year to date earnings were
$15.9 million or $1.42 per share, compared to $11.6 million or $1.04 per share
last year.

     Third Quarter Results

     Total operating margins (revenue minus gas costs and revenue taxes) were
down $691,000 from the quarter ended June 30, 2003.

     --   Reductions in residential and commercial per-customer consumption
          attributable, in large part, to 20% warmer temperatures based on
          degree days, accounted for a $1.4 million decrease in
          quarter-to-quarter operating margins.

     --   The Company had an average of 215,000 residential and commercial
          customers in the quarter compared to the fiscal 2003 third quarter, an
          increase of 8,093, or 3.9%, which added $406,000 in operating margin.

     --   Distribution service margins from electric generation customers were
          up for the quarter $210,000 or 14%.

     --   Operating margin from distribution services for industrial customers
          other than electric generators improved by $45,000. Margin from gas
          management and other services was up $71,000 net of a $117,000
          negative mark-to-market valuation for a fixed price swap and cap
          supporting gas sales to a group of industrial customers.

     Cost of Operations (operating expense, depreciation and amortization, and
property and miscellaneous taxes) was $2.7 million lower than the third quarter
last year. In the 2003 third quarter there was a $1.5 million retirement plan
curtailment charge as part of changes made to benefit plans to lower costs.
Re-measurement of Cascade's retiree medical expense, resulting from the recently
enacted Medicare prescription drug subsidy, reduced fiscal year 2004 third
quarter expense $158,000. Excluding the effect of the 2003 curtailment charge
and the Medicare subsidy, benefits expense was $435,000 lower in the current
year third quarter reflecting mainly improvements from benefit plans changes
introduced in July 2003. Consulting expenses were lower by $514,000 in the
current quarter due to completion in 2003 of consulting projects related to
benefits changes and installation of an internal control system for
documentation and reporting. Depreciation expense increased $180,000 from the
fiscal year 2003 third quarter.

     Year-to-Date Results

     Year-to-date operating margin was up $3.0 million over the fiscal 2003.
Residential and commercial margin contributed $871,000 to the increase, due to
higher per-customer consumption levels in December and January and $2.1 million
due to the addition of customers. Electric generation margins were down $666,000
for the period stemming from lower deliveries to electric generation customers
due, in part, to higher gas prices. There was also a $371,000 increase in
industrial distribution margin and $295,000 higher gas management services and
other operating margin including a $358,000 year-to-date favorable
mark-to-market valuation for a fixed price swap and cap supporting gas sales to
a group of industrial customers. Also affecting the gas management services
comparison is the fiscal year 2003 $865,000 gas supply termination charge.
     On a year-to-date basis, total cost of operations was lower than fiscal
2003 by $3.5 million. The favorable result stems from benefit expense savings,
lower project consulting expense, the Medicare prescription drug subsidy, and
the retirement plan curtailment charge in fiscal year 2003. Cascade elected to
implement the effect of the Medicare prescription subsidy on a retroactive basis
to the second quarter resulting in a $158,000 reduction for the second quarter,
$158,000 for the third quarter and prospectively $158,000 for the fourth
quarter. Year-to-date expense is reduced $316,000 and for the full year the
effect will be $474,000. Depreciation expense was up $415,000 for the year
consistent with additions to plant.

     Capital Expenditures

     Third quarter net capital expenditures were $9.6 million and for the
year-to-date expenditures were $29.4 million out of a total updated budget for
the fiscal year of $38.0 million. The major expenditure continues to be the
automated meter-reading project started in July of 2003. This year $9.2 million
has been expended installing the new features on customer meters, and
project-to-date expenditures have been $12.8 million of a total project budget
of $16 million. It is expected the project will be completed by September 30,
2004.

     Full Fiscal Year Expectations

     The Company confirms its earlier fiscal year 2004 guidance of $1.05 to
$1.15.
     The Company previously announced its declaration of a $0.24 per share
quarterly dividend on common stock, payable August 13, 2004, to shareholders of
record at the close of business July 30, 2004.
