Notes to Consolidated Financial Statements (Unaudited)
------------------------------------------------------


Note 1: Basis of Presentation
-----------------------------

   PG&E Gas Transmission, Northwest Corporation (GTN), incorporated in
California in 1957, is affiliated with, but is not the same company as, Pacific
Gas and Electric Company, the gas and electric company serving Northern and
Central California. PG&E Corporation is the ultimate corporate parent for both
GTN and Pacific Gas and Electric Company.

   The accompanying unaudited consolidated financial statements, which have been
prepared in accordance with interim period reporting requirements, reflect the
results for GTN and its wholly owned subsidiaries, Pacific Gas Transmission
Company and Pacific Gas Transmission International, Inc.

   GTN and its subsidiaries are collectively referred to herein as the
"Company." This information should be read in conjunction with the Consolidated
Financial Statements and Notes to Consolidated Financial Statements included in
Item 8, Financial Statements and Supplementary Data, in the Company's Form 10-K
for the fiscal year ended December 31, 1999.

   In the opinion of management, the accompanying statements reflect all
adjustments necessary to present a fair statement of the financial position and
results of operations for the interim periods.  All material adjustments are of
a normal recurring nature unless otherwise disclosed in this Form 10-Q.
Subsidiary intercompany accounts and transactions have been eliminated.  Prior
year's amounts in the consolidated financial statements have been reclassified
where necessary to conform to the 2000 presentation.  Results of operations for
interim periods are not necessarily indicative of results to be expected for a
full year.

Note 2: Commitments and Contingencies
--------------------------------------

   In the normal course of business, the Company is named as a party in a number
of claims and lawsuits.  In the past, substantially all of these have been
litigated or settled with no significant impact on either the Company's results
of operations, financial position, or cash flows.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
            -------------------------------------------------
            CONDITION AND RESULTS OF OPERATIONS
            -----------------------------------


GENERAL
-------

   The unaudited consolidated financial statements include GTN and its wholly
owned subsidiaries.

   GTN and its subsidiaries are collectively referred to herein as the
"Company." This information should be read in conjunction with the Consolidated
Financial Statements and Notes to Consolidated Financial Statements included in
Item 8, Financial Statements and Supplementary Data in the Company's Form 10-K
for the fiscal year ended December 31, 1999.

   The following discussion includes forward-looking statements that involve a
number of risks, uncertainties, and assumptions.  When used in Management's
Discussion and Analysis of Financial Condition and Results of Operations, words
such as "estimates," "expects," "intends," "anticipates," "plans," and similar
expressions identify those statements which are forward-looking.  Actual results
may differ materially from those expressed in the forward-looking statements.
The important factors that could cause actual results to differ materially from
those expressed in the forward-looking statements include, but are not limited
to, the ongoing restructuring of the gas industry, changes in future rate-
making, increasing competition for natural gas supplies, and the ability of the
Company to expand its core pipeline business.

   GTN's transportation system provides access to natural gas from producing
fields in western Canada and extends from the British Columbia-Idaho border to
the Oregon-California border.  GTN's transportation system also provides service
to various delivery points in Idaho, Washington, and Oregon.  GTN's natural gas
transportation services are regulated by the Federal Energy Regulatory
Commission (FERC or the Commission).  Various safety issues are subject to the
jurisdiction of the United States Department of Transportation.

CHANGING REGULATORY ENVIRONMENT
-------------------------------

   In February 2000, FERC issued Order 637 to promote competition in the short-
term transportation market.  The order lifted the rate cap for short-term
capacity release transactions for a period of two years and established new
reporting requirements that would increase price transparency for short-term
capacity.  The removal of the price cap only applies to capacity release
transactions and is unlikely to provide any material short-term benefits to GTN.
The Order also modified regulations related to certain pipeline system
operations, such as scheduling procedures, capacity segmentation and penalties.
GTN will be required to make minor changes to its system to implement the new
regulations.  FERC also issued a Statement of Policy in September 1999
addressing certification of new interstate natural gas facilities.  Among other
things, this Statement of Policy has modified on a prospective basis the
Commission's guidelines for evaluating the market need and pricing of new
pipeline capacity.

   These regulatory initiatives are not expected to have a material impact on
GTN's financial position, liquidity or results of operations in the foreseeable
future.

ACCOUNTING FOR THE EFFECTS OF REGULATION
----------------------------------------

   GTN currently accounts for the financial effects of regulation in accordance
with the provisions of Statement of Financial Accounting Standards (SFAS) No.
71, "Accounting for the Effects of Certain Types of Regulation."  As a result of
applying the provisions of SFAS No. 71, GTN has accumulated approximately $41.9
million of regulatory assets and $4.7 million of regulatory liabilities as of
June 30, 2000.

  Net Income - Income for the three and six month periods ended June 30, 2000
increased $1.7 million and $2.3 million, respectively, compared to the same
periods in 1999. The increases in the 2000 periods were primarily the result of
higher operating revenues.

  Operating Revenues - Operating revenues for the three and six month periods
ended June 30, 2000 increased $4.7 million and $3.8 million, respectively,
compared to the same periods in 1999. The increases in the three month and six
month periods ended June 2000 reflect a refund to customers of $3.9 million in
GRI surcharges in May 1999 as ordered by FERC, effectively reducing revenues in
the 1999 reporting periods. The additional increase in the three months ended
June 2000 was due to greater short-term firm and interruptible service revenues.

  Operating Expenses - The components of total operating expenses are as
follows:

</TABLE>


  For the three and six month periods ended June 30, 2000, compared with the
same periods in 1999, operating expenses increased $1.8 million and decreased
$0.4 million, respectively. The increase in the three-month period reflects
increased administrative and general expenses driven primarily by a credit of
$3.9 million for the Gas Research Institute refund in 1999, partially offset by
lower operations and maintenance expenses in 2000. Total operating expenses were
comparable in the six month periods ended June 30, 2000 and 1999 as additional
reorganization costs in 1999 partly offset the effect of the Gas Research
Institute refund.

  Interest Expense - Interest expense for the three and six month periods ended
June 30, 2000 decreased $0.3 million and $0.1 million, respectively, compared to
the same periods in 1999. The lower average debt balance was somewhat offset by
higher interest rates. For the three months ended June 30, 2000 and 1999, the
average interest rate was approximately 7.6 percent and 7.2 percent,
respectively, while the average balance of long-term debt (excluding capital
lease obligations) outstanding was $522 million and $570 million, respectively.
For the six months ended June 30, 2000 and 1999, the average interest rate was
approximately 7.5 percent and 7.2 percent, respectively, while the average
balance of long-term debt (excluding capital lease obligations) outstanding was
$538 million and $574 million, respectively.

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

  Sources of Capital - The Company's capital requirements are funded from cash
provided by operations and, to the extent necessary, external financing and
capital contributions from its parent company. GTN has paid dividends as part of
a balanced approach to managing its capital structure, funding its operations
and capital expenditures, and maintaining appropriate cash balances.

  Net Cash Provided by Operating Activities - For the six months ended June 30,
2000, net cash provided by operating activities was $64.4 million, compared with
$55.2 million for the same period in 1999. The $9.2 million increase was
primarily due to the timing of payment on affiliate balances and additional net
income.

  Net Cash Used in Investing Activities - For the six months ended June 30,
2000, compared to the same period in 1999, net cash used in investing activities
decreased $12.4 million. The decrease primarily reflects lower construction
expenditures in 2000.

  Net Cash Used in Financing Activities - For the six months ended June 30,
2000, cash used in financing activities was $59.7 million reflecting a net
decrease in long-term debt. For the six months ended June 30, 1999, cash used in
financing activities was $38.3 million resulting from a $30 million dividend and
from a net decrease in long-term debt of $8.3 million.

NEW ACCOUNTING STANDARD
-----------------------

  SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities",
as amended by SFAS No. 138, will require the recognition of all derivatives, as
defined in the Statement, on the balance sheet at fair value. Derivatives, or
any portion thereof, that are not effective hedges must be adjusted to fair
value through income. If the derivative is an effective hedge, depending on the
nature of the hedge, changes in the fair value of derivatives either will be
offset against the change in fair value of the hedged assets, liabilities, or
firm commitments through earnings or will be recognized in other comprehensive
income until the hedged item is recognized in earnings. GTN is currently
evaluating the potential impact of SFAS No. 133. GTN expects to adopt the new
Statement no later than January 1, 2001.
